NUCLEIC ACID MOLECULES ASSOCIATED WITH PLANT CELL PROLIFERATION AND GROWTH AND USES THEREOF

Abstract: The present invention provides a gene encoding ANT-like polypeptide comprising in the N-terminal to C-terminal direction two AP2 DNA binding domains followed in the C-terminal by an amino acid subsequence selected from the group consisting of Xaa-Ser-Ser-Ser-Arg-Glu, Aaa-Ser-Asn-Ser-Arg-Glu, and Asn-Ser-Ser-Ser-Arg-Asn, wherein Xaa is an amino acid residue selected from the group consisting of Gly, Ala, Val, Leu, and Ile. Such gene encoding ANT-like polypeptide can be over-expressed in a transgenic plant to provide agronomically desired traits based on increased size of plant organs.

Description: NUCLEIC ACID MOLECULES ASSOCIATED WITH PLANT CELL PROLIFERATION AND GROWTH AND USES THEREOF FIELD OF THE INVENTION Described herein are inventions in the field of plant molecular biology and plant genetic engineering, including isolated nucleic acid molecules encoding AINTEGUMENTA-like {ANT- like) polypeptides that are useful in improving agronomic, horticultural and quality traits of plants. In addition, polypeptides so encoded and antibodies capable of binding the polypeptides are encompassed by the present invention. The present invention also relates to methods of identifying and isolating nucleic acid molecules encoding ANT-like polypeptides. Also disclosed are polypeptides, antibodies, recombinant DNA constructs, transgenic plants characterized by the increased size of plant organs, methods for making and using the nucleic acid molecules, polypeptides, antibodies, and recombinant DNA constructs. BACKGROUND OF THE INVENTION One of the goals of plant genetic engineering is to produce plants with agronomically, horticulturally or economically important characteristics or traits. Traits of particular interest include high yield, improved quality and high stability. Although the yield from a plant is influenced greatly by external environmental factors, it appears that the yield of the plant is determined, in part, by the intrinsic size of various organs/tissues (such as seeds, fruits, roots, leaves, tubers, stems, and bulbs) which are in turn determined by internal developmental factors. Enhancement of the yield of a plant may be achieved by genetically modifying the plant so that the intrinsic size of plant organs is increased. Plants have unique developmental features that distinguish them from other eukaryotes. Plant cells do not undergo migration. It is thus believed that cell division and cell expansion are the predominant mechanisms by which the number and position of organ primordia are determined and also by which the intrinsic size and shape of each of plant organs are controlled. It is also believed that there are developmental regulators that control cell proliferation and growth and intrinsic size of plant organs. When interacting with external environmental factors, the developmental regulators determine the eventual size of plant organs. Therefore, identification/isolation of developmental regulators that control cell proliferation and growth and the intrinsic size of organs would be desirable. Such developmental regulators could be used in the genetic engineering to produce transgenic plants having increased intrinsic size of organs of interest and subsequently higher yield. Gu et al. {Development 725:1509-1517 (1998)) recently reported that the Arabidopsis AGL8 gene, a MADS-box gene, might be involved in mediating cell differentiation in Arabidopsis plants during fruit and leaf development. Like AGAMOUS and other plant MADS- box genes, AGL8 encodes a polypeptide of about 260 amino acids including a highly conserved DNA-binding MADS domain of about 56 amino acids (Riechmann and Meyerowitz, Biol. Chem. 57S:1079-1101 (1997)). They also reported that the ectopic expression of the AGL8 gene under control of a constitutive promoter in Arabidopsis plants could increase the size of seeds and fruits and delay senescence in the transgenic Arabidopsis plants (WO 99/00503). The Arabidopsis APETALA2 {AP2) gene has recently been shown to be able to control seed mass in transgenic Arabidopsis and tobacco plants (WO 97/14659). The AP2 polypeptide contains two tandemly repeated 68-amino acid motifs designated as AP2 DNA binding domain (Jofuku, et al, Plant Cell 5:1211-1225 (1994), which are homologous to the DNA binding domain of ethylene response element binding polypeptides. Several studies suggested that the AP2 gene is a homeotic gene which controls three processes during flower development in Arabidopsis plants: (1) the establishment of flower meristem identity (Irish and Sussex, Plant cell 2:741-753 (1990); Bowman et al, Development 119:121-143 (1993)); (2) the specification of flower organ identity and regulation of floral organogenesis (Komaki et al, Development 104: 195-203 (1988); Bowman et al, Plant Cell 1:31-42 (1989); Bowman et al, Development 112:1-20 (1991); Kunst et al, Plant Cell 1:1195-1208 (1989); Jofuku et al, Plant Cell 5:1211- 1225 (1994)); and (3) the temporal and spatial regulation of flower homeotic gene activity (Drews et al, Cell 55:991-1002 (1991)). Genetic studies have shown that AP2 gene is also required for normal ovule and seed development (Jofuku et al, Plant Cell 5:1211-1225 (1994); Leon-Kloosterziel et al, Plant Cell 5:385-392 (1994); and Modrusan et al, Plant Cell 5:339-349 (1994)). Transgenic Arabidopsis plants, where the AP2 gene was expressed in the antisense orientation under the control of the cauliflower mosaic virus 35S constitutive promoter, produced seed with increased mass and total protein and fatty acid contents (WO 97/14659). Arabidopsis and tobacco transgenic plants, where the AP2 gene was overexpressed in the sense orientation under control of the cauliflower mosaic virus 35S constitutive promoter, produced seed with decreased mass and decreased total protein content (WO 97/14659). It has been shown by two recent studies that the AINTEGUMENTA {ANT) gene of Arabidopsis might play a role in regulating cell growth and cell numbers during organogenesis (Mizukami and Fisher, Proc. Natl. Acad. Sci. USA 97:942-941 (2000); Krizek, Develop. Genet. 25:224-236 (1999)). The ANT gene belongs to the large AP2 gene family and encodes a transcription factor that may play a critical role in regulating ovule and female gametophyte development (Klucher et al, Plant Cell 5:137-153 (1996); Elliott et al, Plant Cell 5:155-168 (1996)). In one study (Mizukami and Fisher, Proc. Natl. Acad. Sci. USA 97:942-941 (2000)), it was reported that when the ANT gene was ectopically expressed in Arabidopsis plants under the control of a cauliflower mosaic virus 35S constitutive promoter, the leaves, stems, pedicels, sepals, petals, stamens, gynocia, ovules, and fruits of the transgenic plants were dramatically enlarged without altering their superficial morphology. Mass of leaves and flowers was increased as much as three times over those in control plants, due to the ectopic expression of the ANT gene. Ectopic expression of the ANT gene in tobacco plant also resulted in organs of increased size comparing to wild type. However, the transgenic plants containing a 35S/ ANT expression construct were male sterile and most transgenic plants containing a 35S/ ANT expression construct were also female sterile. Only Tl plants expressing relatively low levels of the ANT gene could generate seeds when pollinated by hand with wild-type pollen. In the other study, Krizek (Krizek, Develop. Genet. 25:224-236 (1999)) reported that ectopic expression of the ANT gene under the control of a cauliflower mosaic virus 35S constitutive promoter produced larger floral organs without altering the number and shape of these organs. The transgenic plants containing a 35SΛ4NE expression construct were male sterile and showed severe reduction in female fertility. Krizek did not observe the increased size of vegetative organs. No DNAs encoding ^ 4NE-like polypeptides in other plants, especially corn, soybean, rice and cotton, have been isolated, sequenced or functionally characterized. Considering that the complex nature of organ size control in plants and that the genetic basis for plant interspecies diversity of phenotype might be minor changes in the structure or expression of orthologous regulatory genes (Doebley and Lukens, Plant Cell i0:1075-1082 (1998); Somerville and Somerville, Science 255:380-383 (1999)), there is a great deal of interest in identifying in plants the genes that, like ANT gene, may be used to control the intrinsic organ size of plants when ectopically expressed in plant cells and subsequently enhance the economic yield of plants. SUMMARY OF THE INVENTION The present invention, in one aspect, provides an isolated nucleic acid molecule comprising a nucleotide sequence or complement thereof, wherein the nucleotide sequence encodes an ^ 4NE-like polypeptide having in the Ν-terminal to C-terminal direction two AP2 DΝA binding domains followed in the C-terminal by an amino acid subsequence selected from the group consisting of Xaa-Ser-Ser-Ser-Arg-Glu, Xaa-Ser-Asn-Ser-Arg-Glu, and Asn-Ser-Ser- Ser-Arg-Asn, wherein Xaa is an amino acid residue having an aliphatic side chain and selected from the group consisting of Gly, Ala, Val, Leu, and He.

The isolated nucleic acid molecules of the present invention may further comprise an operably linked promoter or partial promoter region. The promoter can be a constitutive promoter, an inducible promoter or a tissue-specific promoter.

The tissue-specific promoter can be active in vegetative tissue or reproductive tissue. The tissue-specific promoter active in reproductive tissue can be a seed-specific promoter. The tissue-specific promoter active in vegetative tissue can be a root-specific, shoot-specific, meristem-specific or leaf-specific promoter. The isolated nucleic acid molecule of the present invention can still further comprise a 5' non-translated sequence, 3' non-translated sequence, introns, or the combination thereof.

The present invention also provides a transformed plant comprising in its genome an isolated nucleic acid molecule which comprises: (A) a 5' non-coding sequence which functions in the cell to cause the production of an mRΝA molecule; which is operably linked to (B) a structural nucleotide sequence, wherein the structural nucleotide sequence encodes a polypeptide the amino acid sequence of which has at least 60% sequence identity to a member selected from group consisting of SΕQ ID ΝOs: 2, 4, 6, 9, 11, and 13; which is operably linked to (C) a 3' non- translated sequence that functions in said cell to cause termination of transcription. The present invention also provides a method for increasing the size of one or more plant organs of a plant by expressing ectopically a nucleic acid molecule that encode a polypeptide the amino acid sequence of which has at least 60% sequence identity to a member selected from the group consisting of SΕQ ID ΝOs: 2, 4, 6, 9, 11, and 13 or comprises in the Ν-terminal to C- terminal direction two AP2 DΝA binding domains followed in the C-terminal by an amino acid subsequence selected from group consisting of Xaa-Ser-Ser-Ser-Arg-Glu, Xaa-Ser-Asn-Ser- Arg-Glu, and Asn-Ser-Ser-Ser-Arg-Asn, wherein Xaa is an amino acid residue having an aliphatic side chain and selected from the group consisting of Gly, Ala, Nal, Leu, and lie.

The exogenous nucleic acid molecule may optionally include introns, 5' untranslated leader sequences or other nucleotide sequences designed to enhance transcription and/or translation. The present invention further provides a plant tissue, such as a seed, which is derived from a transformed plant of the present invention. The present invention also further provides a method for selecting a plant having increased size of plant organs, said method comprising the steps of: (A) obtaining genomic DΝA from a plurality of plants; (B) analyzing genomic DΝA from each of the plurality of plants to determine the presence or absence of a DΝA marker that is genetically linked to a nucleotide sequence complementary to a nucleotide sequence selected from the group consisting of SΕQ ID ΝOS: 1, 3, 5, 1, 10, and 12 or complements thereof; and (C) selecting said plant containing said DΝA marker.

The invention can be more fully understood from the following detailed description and the accompanying Sequence Listing which form a part of this application. DETAILED DESCRIPTION OF THE INVENTION The present invention is based, in part, on the isolation and characterization of nucleic acid molecules encoding ^NE-like polypeptides from plants including soybean, maize, rice, and cotton. The ,4NE-like polypeptides of the present invention, like the ANT polypeptide of Arabidopsis, contain two highly conserved AP2 DΝA-binding domains. It has also been discovered that the ^4NE-like polypeptides of the present invention and the Arabidopsis ANT polypeptide comprise three highly conserved regions in the Ν-terminal before the AP2 DΝA binding domains, and one conserved region in the end of the C-terminal. However, the polypeptides encoded by the nucleic acid molecules disclosed herein share less than 60% amino acid sequence identity to the Arabidopsis ANT polypeptide or less than 60%> nucleotide sequence identity to the nucleic acid molecule encoding Arabidopsis ANT polypeptide, as shown in Tables 1 and 2. In addition, the C-terminal of each of the ANT-like polypeptides disclosed herein is longer than that of the Arabidopsis ANT polypeptide after the AP2 DNA binding domains. Finally, two additional conserved regions (shaded) in the C-terminus are only present in the ANT-like polypeptides of the present invention but absent in the Arabidopsis ANT polypeptide. A "crop ANT protein" as used herein is a protein with substantial identity to SEQ ID NOs: 2, 4, 6, 9, 11, and 13 or which comprises a polypeptide having in the N-terminal to C-terminal direction two AP2 DNA binding domains followed in the C-terminal by an amino acid subsequence selected from the group consisting of Xaa-Ser-Ser-Ser- Arg-Glu (SEQ ID NO: 25), Xaa-Ser-Asn- Ser-Arg-Glu (SEQ ID NO: 26), and Asn-Ser-Ser-Ser-Arg-Asn (SEQ ID NO: 27), wherein Xaa is an amino acid residue selected from the group consisting of Gly, Ala, Val, Leu, and He.

In a preferred embodiment, the amino acid subsequence is selected from the group consisting of Ser-Ser-Leu-Xaa-Thr-Ser-Xaa-Ser-Ser-Ser- Arg-Glu, Ser-Ser-Leu-Xaa-Pro-Ser-Xaa-Ser-Asn-Ser-Arg-Glu, Ser-Ser-Leu-Xaa-Thr-Ser-Xaa- Ser-Asn-Ser-Arg-Glu, and Ser-Leu-Xaa-Asn-Ser-Ser-Ser-Arg-Asn. In a particular preferred embodiment, the polypeptide of the present invention further comprises a second amino acid subsequence selected from the group consisting of Leu-Gly-Phe-Ser-Leu-Ser, Leu-Gly-Phe-Ser- Leu-Thr, Met-Pro-Leu-Lys-Ser-Asp-Gly-Ser, Met-Pro-Leu-Arg-Ser-Asp-Gly-Ser, Met-Pro-Ile- Lys-Ser-Asp-Gly-Ser, Pro-Lys-Leu-Glu-Asp-Phe, and Pro-Lys-Val-Glu-Asp-Phe. The term "nucleic acid molecule" as used herein means a deoxyribonucleic acid (DNA) molecule or ribonucleic acid (RNA) molecule. Both DNA and RNA molecules are constructed from nucleotides linked end to end, wherein each of the nucleotides contains a phosphate group, a sugar moiety, and either a purine or a pyrimidine base. Nucleic acid molecules can be a single or double-stranded polymer of nucleotides read from the 5' to the 3' end. Nucleic acid molecules may also optionally contain synthetic, non-natural or altered nucleotide bases that permit correct read through by a polymerase and do not alter expression of a polypeptide encoded by that nucleic acid molecule. The term "an isolated nucleic acid molecule" as used herein means a nucleic acid molecule that is no longer accompanied by some of materials with which it is associated in its natural state or to a nucleic acid molecule the structure of which is not identical to that of any of naturally occurring nucleic acid molecule. Examples of an isolated nucleic acid molecule include: (1) DNAs which have the sequence of part of a naturally occurring genomic DNA molecule but are not flanked by two coding sequences that flank that part of the molecule in the genome of the organism in which it naturally occurs; (2) a nucleic acid molecule incorporated into a vector or into the genomic DNA of a prokaryote or eukaryote in a manner such that the resulting molecule is not identical to any naturally occurring vector or genomic DNA; (3) a separate molecule such as a cDNA, a genomic fragment, a fragment produced by polymerase chain reaction (PCR), or a restriction fragment; (4) recombinant DNAs; and (5) synthetic DNAs. An isolated nucleic acid molecule may also be comprised of one or more segments of cDNA, genomic DNA or synthetic DNA. It is also contemplated by the inventors that the isolated nucleic acid molecules of the present invention also include known types of modifications, for example, labels which are known in the art, methylation, "caps", substitution of one or more of the naturally occurring nucleotides with an analog. Other known modifications include intemucleotide modifications, for example, those with uncharged linkages (methyl phosphonates, phosphotriesters, phosphoamidates, carbamates, etc.) and with charged linkages (phosphorothioates, phosphorodithioates, etc.), those containing pendant moieties, such as, proteins (including nucleases, toxins, antibodies, signal peptides, poly-L-lysine, etc.), those with intercalators (acridine, psoralen, etc.), those containing chelators (metals, radioactive metals, boron, oxidative metals, etc.), those containing alkylators, and those with modified linkages. The term "nucleotide sequence" as used herein means both the sense and antisense strands of a nucleic acid molecule as either individual single strands or in the duplex. It includes, but is not limited to, self-replicating plasmids, chromosomal sequences, and infectious polymers ofDNA or RNA. A nucleotide sequence is said to be the "complement" of another nucleotide sequence if they exhibit complete complementarity. As used herein, molecules are said to exhibit "complete complementarity" when every nucleotide of one of the sequences is complementary to a nucleotide of the other. As used herein both terms "a coding sequence" and "a structural nucleotide sequence" mean a nucleotide sequence which is translated into a polypeptide, usually via mRNA, when placed under the control of appropriate regulatory sequences. The boundaries of the coding sequence are determined by a translation start codon at the 5 '-terminus and a translation stop codon at the 3 '-terminus. A coding sequence can include, but is not limited to, genomic DNA, cDNA, and recombinant nucleotide sequences. The ^INE-like polypeptides of the invention, like other polypeptides, have different domains which perform different functions. Thus, the coding sequences need not be full length, so long as the desired functional domain of the polypeptide is expressed. The distinguishing features of ANT-like polypeptides are discussed in detail in Examples. The term "recombinant DΝAs" or "recombinant DΝA molecules" as used herein means DΝAs that contains a genetically engineered modification through manipulation via mutagenesis, restriction enzymes, and the like. The nucleic acid itself can come form either naturally occurring sources or can be created in the laboratory. It can also include all vectors created by DΝA engineering, for example, all the DΝA molecules included herein designated by pMOΝ. For example, it can include molecules containing naturally occurring DΝA or cDΝA, or DΝA molecules of synthetic origin in a plasmid, or isolated. The term "synthetic DΝAs" as used herein means DΝAs assembled from oligonucleotide building blocks that are chemically synthesized using procedures known to those skilled in the art. These building blocks are ligated and annealed to form DΝA segments which are then enzymatically assembled to construct the entire DΝA. "Chemically synthesized", as related to a sequence of DΝA, means that the component nucleotides were assembled in vitro. Manual chemical synthesis of DΝA may be accomplished using well established procedures, or automated chemical synthesis can be performed using one of a number of commercially available machines. Both terms "polypeptide" and "protein", as used herein, mean a polymer composed of amino acids connected by peptide bonds. An amino acid unit in a polypeptide (or protein) is called a residue. The terms "polypeptide" and "protein" also applies to any amino acid polymers in which one or more amino acid residue is an artificial chemical analogue of a corresponding naturally occurring amino acid, as well as to any naturally occurring amino acid polymers. The essential nature of such analogues of naturally occurring amino acids is that, when incorporated into a polypeptide, that polypeptide is specifically reactive to antibodies elicited to the same polypeptide but consisting entirely of naturally occurring amino acids. It is well known in the art that proteins or polypeptides may undergo modification, including but not limited to, disulfide bond formation, gamma-carboxylation of glutamic acid residues, glycosylation, lipid attachment, phosphorylation, oligomerization, hydroxylation and ADP-ribosylation. Exemplary modifications are described in most basic texts, such as, for example, Proteins - Structure and Molecular Properties, 2nd ed., T. E. Creighton, W. H. Freeman and Company, New York (1993), herein incorporated by reference in its entirety. Many detailed reviews are available on this subject, such as, for example, those provided by Wold, F., Post-translational Protein Modifications. Perspectives and Prospects, pp. 1-12 in Post-translational Covalent Modification of Proteins, B. C. Johnson, Ed., Academic Press, New York (1983); Seifter et al., Meth. Enzymol 182:626-M (1990) and Rattan et al., Protein Synthesis: Post-translational Modifications and Aging, Ann. N.Y. Acad. Sci. 555:48-62 (1992), herein incorporated by reference in their entirety. Modifications can occur anywhere in a polypeptide, including the peptide backbone, the amino acid side-chains and the amino or carboxyl termini. In fact, blockage of the amino or carboxyl group in a polypeptide, or both, by a covalent modification, is common in naturally occurring and synthetic polypeptides and such modifications may be present in polypeptides of the present invention, as well. For instance, the amino terminal residue of polypeptides made in E. coli or other cells, prior to proteolytic processing, almost invariably will be N-formylmethionine. During post-translational modification of the polypeptide, a methionine residue at the NH 2 terminus may be deleted. Accordingly, this invention contemplates the use of both the methionine-containing and the methionine-less amino terminal variants of the polypeptide of the invention. Thus, as used herein, the terms "protein" and "polypeptide" include any protein or polypeptide that is modified by any biological or non- biological process. The terms "amino acid" and "amino acids" refer to all naturally occurring amino acids and, unless otherwise limited, known analogs of natural amino acids that can function in a similar manner as naturally occurring amino acids. This definition is meant to include norleucine, ornithine, homocysteine, and homoserine. The term "amino acid sequence" means the sequence of amino acids in a polypeptide (or protein) that is written starting with the amino-terminal (N-terminal) residue and ending with the carboxyl-terminal (C-terminal) residue. The term "an amino acid subsequence" means a portion of the amino acid sequence of a polypeptide. An amino acid subsequence generally has a length of 3 to 50 amino acid residues. Both terms "substantially purified polypeptide" and "substantially purified protein", as used herein, means a polypeptide or protein that is separated substantially from all other olecules normally associated with it in its native state andp is the predominant species present in a preparation. A substantially purified molecule may be greater than 60% free, preferably 75% free, more preferably 90% free, and most preferably 95% free from the other molecules (exclusive of solvent) present in the natural mixture. As used herein the term "AP2 DNA binding domain" means a 68 amino acid motif found in the Arabidopsis APETALA2 {AP2) polypeptide as reported by Jofuku, et al, Plant Cell 5: 121 1-1225 (1994) and in WO 97/14659 as being homologous to the DNA binding domain of ethylene response element binding proteins. With reference to Figures 2a and 2b for pmposes of defining amino acid sequence of polypeptides of the present invention an AP2 DNA binding domain means an amino acid motif the amino acid sequence of which is determined to have at least 85% sequence identity to the amino acid sequence of the Arabidopsis ANT polypeptide (gi 1244708) between amino acid 281 and amino acid 354 or between amino acid 383 and amino acid 448, using the Gap program in the WISCONSIN PACKAGE version 10.0-UNIX from Genetics Computer Group, Inc. based on the method of Needleman and Wunsch (J. Mol. Biol. 48:443-453 (1970), herein incorporated by reference in its entirety) using the set of default parameters for pairwise comparison (for amino acid sequence comparison: Gap Creation Penalty = 8, Gap Extension Penalty = 2). "Percentage of sequence identity" is determined by comparing two optimally aligned sequences over a comparison window, wherein the portion of the polynucleotide or amino acid sequence in the comparison window may comprise additions or deletions (i.e., gaps) as compared to the reference sequence (which does not comprise additions or deletions) for optimal alignment of the two sequences. The percentage is calculated by determining the number of positions at which the identical nucleic acid base or amino acid residue occurs in both sequences to yield the number of matched positions, dividing the number of matched positions by the total number of positions in the window of comparison and multiplying the result by 100 to yield the percentage of sequence identity. As used herein the term "_4NE-like polypeptide" means a polypeptide, wherein the overexpression of an exogenous nucleic acid molecule encoding said polypeptide in a transgenic plant wherein the amino acid sequence of said polypeptide is substantially identical to a sequence selected from the group consisting of SEQ ID Nos: 2, 4, 6, 9, 11, and 13. Preferably, the overexpression of an exogenous nucleic acid molecule encoding an ANT-like polypeptide of the present invention under the control of a constitutive promoter in a transgenic plant will have minimal effects on the female fertility or male fertility or both thereof of the trangenic plant. The term "intrinsic size" as used herein means the size of an organ or tissue of a plant, that is grown under optimal growth conditions, at maturity or any other defining time in its life cycle. Both terms "substantially identical" and "substantial identity", used in reference to amino acid sequences or nucleotide sequences, means that one amino acid sequence or one nucleotide sequence has at least 60% sequence identity compared to the other amino acid sequence or nucleotide sequence as a reference sequence using the Gap program in the WISCONSIN PACKAGE version 10.0-UNIX from Genetics Computer Group, Inc. based on the method of Needleman and Wunsch (J. Mol. Biol. 48:443-453 (1970), herein incorporated by reference in its entirety) using the set of default parameters for pairwise comparison (for amino acid sequence comparison: Gap Creation Penalty = 8, Gap Extension Penalty = 2; for nucleotide sequence comparison: Gap Creation Penalty = 50; Gap Extension Penalty = 3). One aspect of the present invention provides an isolated nucleic acid molecule comprising a nucleotide sequence or complement thereof, wherein the nucleotide sequence encodes a polypeptide having an amino acid sequence that has at least 60% sequence identity, preferably at least 70% or 75% sequence identity, more preferably at least 80% or 85% sequence identity, even more preferably at least 90% or 95% sequence identity, and most preferably at least 98% sequence identity to a member selected from group consisting of SEQ ID NOs: 2, 4, 6, 9, 11, and 13. Polypeptides which are "substantially similar" share sequences as noted above except that residue positions which are not identical may differ by conservative amino acid changes. Conservative amino acid substitutions refer to the interchangeability of residues having similar side chains. "Conservative amino acid substitutions" mean substitutions of one or more amino acids in a native amino acid sequence with another amino acid(s) having similar side chains. Conserved substitutes for an amino acid within a native amino acid sequence can be selected from other members of the group to which the naturally occurring amino acid belongs. For example, a group of amino acids having aliphatic side chains is glycine, alanine, valine, leucine, and isoleucine; a group of amino acids having aliphatic-hydroxyl side chains is serine and threonine; a group of amino acids having amide-containing side chains is asparagine and glutamine; a group of amino acids having aromatic side chains is phenylalanine, tyrosine, and tryptophan; a group of amino acids having basic side chains is lysine, arginine, and histidine; and a group of amino acids having sulfur-containing side chains is cysteine and methionine. Preferred conservative amino acids substitution groups are: valine-leucine, valine-isoleucine, phenylalanine-tyrosine, lysine-arginine, alanine-valine, aspartic acid-glutamic acid, and asparagine-glutamine. One skilled in the art will recognize that the values of the above substantial identity of nucleotide sequences can be appropriately adjusted to determine corresponding sequence identity of two nucleotide sequences encoding the polypeptides of the present invention by taking into account codon degeneracy, conservative amino acid substitutions, reading frame positioning and the like. Substantial identity of nucleotide sequences for these purposes normally means sequence identity of at least 35%. As used herein yeast regularly refers to Saccharomyces cerevissiae but could also include Schizosacchoramyces pombe and other varieties (from the genus Pichia, for example). Corn refers to Zea Mays and all species and varieties that can be bred with it. Wheat refers to all of Triticum aestivum varieties including but not limited to spring, winter, and all facultative wheat varieties. Wheat includes any other wheat species, including but not limited to durum wheat {Triticum durum), spelt {Triticum spelta), emmer {Triticum dicoccum), and wild wheat {Triticum monococcum). Wheat also includes any species that can be bred with any of the aforementioned wheat species and offspring of said crosses (including triticale, a hybrid of wheat and rye). Soybeans refers to Glycine max or Glycine soja and any species or variety that can be bred with them. Rice refers to Oryza sativa and any species or variety that can be bred with it. Barley refers to Hordeum vulgare and any species or variety that can be bred with it. Oats refers to Avena sativa and any species or variety that can be bred with it.

Cotton refers to all plants in the genus Gossypium and all plants that can be bred with them. The term "codon degeneracy" means divergence in the genetic code permitting variation of the nucleotide sequence without effecting the amino acid sequence of an encoded polypeptide. The skilled artisan is well aware of the "codon-bias" exhibited by a specific host cell in usage of nucleotide codons to specify a given amino acid. Therefore, when synthesizing a gene for ectopic expression in a host cell, it is desirable to design the gene such that its frequency of codon usage approaches the frequency of preferred codon usage of the host cell. In another aspect, the present invention provides an isolated nucleic acid molecule comprising a nucleotide sequence or complement thereof, wherein the nucleotide sequence hybridizes under stringent conditions to the complement of a second nucleotide sequence encoding a polypeptide having an amino acid sequence selected from the group consisting of SΕQ ID Nos: 2, 4, 6, 9, 11, and 13. Hybridization conditions are sequence dependent and will be different in different circumstances. As used herein "stringent conditions" are selected to be about 5 °C lower than the thermal melting point (Tm) for the specific sequence at a defined ionic strength and pH. The "thermal melting point" is the temperature (under defined ionic strength and pH) at which 50% of a target molecule hybridizes to a completely complementary molecule. Appropriate stringent conditions which promote DNA hybridization, for example, 6.0 X sodium chloride/sodium citrate (SSC) at about 45°C, followed by a wash of 2.0 X SSC at 50°C, are known to those skilled in the art or can be found in Current Protocols in Molecular Biology, John Wiley & Sons, N.Y. (1989), 6.3.1-6.3.6, incorporated herein by reference in its entirety. For example, the salt concentration in the wash step can be selected from a low stringent condition of about 2.0 X SSC at 50°C to a high stringency of about 0.2 X SSC at 50°C. In addition, the temperature in the wash step can be increased from low stringent conditions at room temperature, about 22°C, to high stringent conditions at about 65°C. Both temperature and salt concentration may be varied, or either the temperature or the salt concentration may be held constant while the other variable is changed. For the purposes of this disclosure, stringent conditions include at least one wash in 2.0 X SSC at a temperature of at least about 50°C for 20 minutes, or equivalent conditions. In a preferred embodiment, an isolated nucleic acid molecule of the present invention comprises a nucleotide sequence or complement thereof, wherein the nucleotide sequence hybridizes under moderately stringent conditions such as 2.0 X SSC and about 65°C to the complement of a second nucleotide sequence encoding a polypeptide having an amino acid sequence selected from the group consisting of SEQ ID Nos: 2, 4, 6, 9, 11, and 13. In a particularly preferred embodiment, an isolated nucleic acid molecule of the present invention comprises a nucleotide sequence or complement thereof, wherein the nucleotide sequence hybridizes under high stringency conditions such as 0.2 X SSC and about 65°C to the complement of a second nucleotide sequence encoding a polypeptide having an amino acid sequence selected from the group consisting of SEQ ID Nos: 2, 4, 6, 9, 11, and 13. The nucleic acid molecules encoding an ^ 4NE-like polypeptide of the present invention may be combined with other non-native, or "heterologous" sequences in a variety of ways. By "heterologous" sequences it is meant any sequence which is not naturally found joined to the nucleotide sequence encoding ^4NE-like polypeptide, including, for example, combinations of nucleotide sequences from the same plant which are not naturally found joined together, or the two sequences originate from two different species. In another aspect, the present invention provides an isolated nucleic acid molecule comprising a structural nucleotide sequence and operably linked regulatory sequences, wherein the structural nucleotide sequence encodes a polypeptide having an amino acid sequence that is substantially identical to a member selected from group consisting of SΕQ ID ΝOs: 2, 4, 6, 9, 11, and 13. The term "operably linked", as used in reference to a regulatory sequence and a structural nucleotide sequence, means that the regulatory sequence causes regulated expression of the operably linked structural nucleotide sequence. "Expression" means the transcription and stable accumulation of sense or antisense RNA derived from the nucleic acid molecule of the present invention. Expression may also refer to translation of mRNA into a polypeptide. "Sense" RNA means RNA transcript that includes the mRNA and so can be translated into polypeptide or protein by the cell. "Antisense RNA" means a RNA transcript that is complementary to all or part of a target primary transcript or mRNA and that blocks the expression of a target gene (U.S. Pat. No. 5,107,065, incorporated herein by reference). The complementarity of an antisense RNA may be with any part of the specific gene transcript, i.e., at the 5' non-coding sequence, 3' non- translated sequence, introns, or the coding sequence. "RNA transcript" means the product resulting from RNA polymerase-catalyzed transcription of a DNA sequence. When the RNA transcript is a perfect complementary copy of the DNA sequence, it is referred to as the primary transcript or it may be a RNA sequence derived from post-transcriptional processing of the primary transcript and is referred to as the mature RNA. The term "overexpression" means the expression of a polypeptide encoded by an exogenous nucleic acid molecule introduced into a host cell, wherein said polypeptide is either not normally present in the host cell, or wherein said polypeptide is present in said host cell at a higher level than that normally expressed from the endogenous gene encoding said polypeptide. By "ectopic expression" it is meant that expression of a nucleic acid molecule encoding a polypeptide in a cell type other than a cell type in which the nucleic acid molecule is normally expressed, at a time other than a time at which the nucleic acid molecule is normally expressed or at a expression level other than the level at which the nucleic acid molecule normally is expressed. "Antisense inhibition" means the production of antisense RNA transcripts capable of suppressing the expression of the target polypeptide. "Co-suppression" means the production of sense RNA transcripts capable of suppressing the expression of identical or substantially similar foreign or endogenous genes (U.S. Patent No. 5,231,020, incorporated herein by reference). The term "a gene" means the segment of DNA that is involved in producing a polypeptide. Such segment of DNA includes regulatory sequences preceding (5' non-coding sequences) and following (3' non-coding sequences) the coding region as well as intervening sequences (introns) between individual coding segments (exons). A "Native gene" means a gene as found in nature with its own regulatory sequences. "Chimeric gene" means any gene that is not a native gene, comprising regulatory and coding sequences that are not found together in nature. Accordingly, a chimeric gene may comprise regulatory sequences and coding sequences that are derived from different sources, or regulatory sequences and coding sequences derived from the same source, but arranged in a manner different than that found in nature. "Endogenous gene" means a native gene in its natural location in the genome of an organism. A "foreign gene" means a gene not normally found in the host organism, but that is introduced into the host organism by gene transfer. Foreign genes can comprise native genes inserted into a non-native organism, or chimeric genes. A "transgene" is a gene that has been introduced into the genome by a transformation procedure. "Regulatory sequences" mean nucleotide sequences located upstream (5' non-coding sequences), within, or downstream (3' non-translated sequences) of a structural nucleotide sequence, and which influence the transcription, RNA processing or stability, or translation of the associated structural nucleotide sequence. Regulatory sequences may include promoters, translation leader sequences, introns, and polyadenylation recognition sequences. The term "promoter sequence" means a nucleotide sequence that is capable of, when located in cis to a structural nucleotide sequence encoding a polypeptide, functioning in a way that directs expression of one or more mRNA molecules that encodes the polypeptide. Such promoter regions are typically found upstream of the trinucleotide ATG sequence at the start site of a polypeptide coding region. Promoter sequences can also include sequences from which transcription of transfer RNA (tRNA) or ribosomal RNA (rRNA) sequences are initiated. Transcription involves the synthesis of a RNA chain representing one strand of a DNA duplex. By "representing" it is meant that the RNA is identical in sequence with one strand of the DNA; it is complementary to the other DNA strand, which provides the template for its synthesis. Transcription takes place by the usual process of complementary base pairing, catalyzed and scrutinized by the enzyme RNA polymerase. The reaction can be divided into three stages described as initiation, elongation and termination. Initiation begins with the binding of RNA polymerase to the double stranded (DS or ds) DNA. The sequence of DNA required for the initiation reaction defines the promoter. The site at which the first nucleotide is incorporated is called the start-site or start-point of transcription. Elongation describes the phase during which the enzyme moves along the DNA and extends the growing RNA chain. Elongation involves the disruption of the DNA double stranded structure in which a transiently unwound region exists as a hybrid RNA-DNA duplex and a displaced single strand of DNA. Termination involves recognition of the point at which no further bases should be added to the chain. To terminate transcription, the formation of phosphodiester bonds must cease and the transcription complex must come apart. When the last base is added to the RNA chain, the RNA-DNA hybrid is disrupted, the DNA reforms into a duplex state, and the RNA polymerase enzyme and RNA molecule are both released from the DNA. The sequence of DNA required for the termination reaction is called the terminator. The promoter sequence consists of proximal and more distal upstream elements, the latter elements often referred to as enhancers. Accordingly, an "enhancer" is a DNA sequence which can stimulate promoter activity and may be an innate element of the promoter or a heterologous element inserted to enhance the level or tissue-specificity of a promoter. Promoters may be derived in their entirety from a native gene, or be composed of different elements derived from different promoters found in nature, or even comprise synthetic DNA segments. It is understood by those skilled in the art that different promoters may direct the expression of a gene in different tissues or cell types, or at different stages of development, or in response to different environmental conditions. Promoters which are known or are found to cause transcription of DNA in plant cells can be used in the present invention. Such promoters may be obtained from a variety of sources such as plants and plant viruses. A number of promoters, including constitutive promoters, inducible promoters and tissue-specific promoters, that are active in plant cells have been described in the literature. It is preferred that the particular promoter selected should be capable of causing sufficient expression to result in the production of an effective amount of a polypeptide to cause the desired phenotype. In addition to promoters that are known to cause transcription of DNA in plant cells, other promoters may be identified for use in the current invention by screening a plant cDNA library for genes that are selectively or preferably expressed in the target tissues and then determine the promoter regions. The term "constitutive promoter" means a regulatory sequence which causes expression of a structural nucleotide sequence in most cells or tissues at most times. Constitutive promoters are active under most environmental conditions and states of development or cell differentiation. A variety of constitutive promoters are well known in the art. Examples of constitutive promoters that are active in plant cells include but are not limited to the nopaline synthase (NOS) promoters; the cauliflower mosaic virus (CaMV) 19S and 35S (sometimes called 35S herein, or a derivative of which is called e35S {US patents 5,359,142, 5,196,525, 5,322,938, 5,164,316, and 5,424,200}); the tobacco mosaic virus promoter; the figwort mosaic virus promoters; and actin promoters, such as the Arabidopsis actin gene promoter (see, e.g., Huang et al, Plant Mol. Biol. 55:125-139 (1997), herein incorporated by reference in its entirety). The term "inducible promoter" means a regulatory sequence which causes conditional expression of a structural nucleotide sequence under the influence of changing environmental conditions or developmental conditions. Examples of inducible promoters include but are not limited to the light-inducible promoter from the small subunit of ribulose-l,5-bis-phosphate carboxylase (ssRUBISCO); the drought-inducible promoter of maize (Busk et al, Plant J. 11: 1285-1295 (1997), herein incorporated by reference in its entirety); the cold, drought, and high salt inducible promoter from potato (Kirch, Plant Mol. Biol. 55:897-909 (1997), herein incorporated by reference in its entirety); a nitrate-inducible promoter derived from the spinach nitrite reductase gene (Back et al, Plant Mol. Biol. 17:9 (1991), herein incorporated by its entirety); salicylic acid inducible promoter (Uknes et al, Plant Cell 5:159-169 (1993); Bi et al, Plant J. 5:235-245 (1995) herein incorporated by reference in their entireties); the auxin- response elements El promoter fragment (AuxREs) in the soybean (Glycine max L.) (Liu et al, Plant Physiol 115:391-401 (1997), herein incorporated by reference in its entirety); the auxin- responsive Arabidopsis GST6 promoter (also responsive to salicylic acid and hydrogen peroxide) (Chen et al, Plant J. 10: 955-966 (1996), herein incorporated by reference in its entirety); the auxin-inducible parC promoter from tobacco (Sakai et al, Plant Cell Physiol. 57:906-913 (1996), herein incorporated by reference in its entirety); a plant biotin response element (Streit et al, Mol. Plant Microbe Interact. 10:933-931 (1997), herein incorporated by reference in its entirety); the promoter responsive to the stress hormone abscisic acid (Sheen et al, Science 274:1900-1902 (1996), herein incorporated by reference in its entirety); the maize In2-2 promoter activated by benzenesulfonamide herbicide safeners (De Neylder et al, Plant Cell Physiol 55:568-577 (1997), herein incorporated by reference in its entirety); a tetracycline- inducible promoter, such as the promoter for the Avena sativa L. (oat) arginine decarboxylase gene (Masgrau et al, Plant J. 11:465-413 (1997), herein incorporated by reference in its entirety); and a salicylic acid-responsive element (Stange et al, Plant J. 77:1315-1324 (1997), herein incorporated by reference in its entirety). The term "tissue-specific promoter" means a regulatory sequence that causes transcriptions or enhanced transcriptions of DNA in specific cells or tissues at specific times during plant development, such as in vegetative tissues or reproductive tissues. Examples of tissue-specific promoters under developmental control include promoters that initiate transcription only (or primarily only) in certain tissues, such as vegetative tissues, e.g., roots, leaves or stems, or reproductive tissues, such as fruit, ovules, seeds, pollen, pistols, flowers, or any embryonic tissue. Reproductive tissue specific promoters may be, e.g., ovule-specific, embryo-specific, endosperm-specific, integument-specific, seed coat-specific, pollen-specific, petal-specific, sepal-specific, or some combination thereof. One skilled in the art will recognize that a tissue-specific promoter may drive expression of operably linked sequences in tissues other than the target tissue. Thus, as used herein a tissue-specific promoter is one that drives expression preferentially in the target tissue, but may also lead to some expression in other tissues as well. Another set of preferred promoters are root enhanced or specific promoters such as the CaMN derived 4 as-1 promoter or the wheat POX1 ( also sometime called poxl) promoter (U.S. Pat. No. 5,023,179, specifically incorporated herein by reference; Hertig et al., 1991). A variety of promoters specifically active in vegetative tissues, such as leaves, stems, roots and tubers, can be used to express the nucleic acid molecules of the present invention. Examples of tuber-specific promoters include but are not limited to- the class I and II patatin promoters (Bevan et al., EMBO J. 8: 1899-1906 (1986); Koster-Topfer et al, Mol Gen Genet. 279: 390-396 (1989); Mignery et al., Gene. 62: 27-44 (1988); Jefferson et al, Plant Mol. Biol 14: 995-1006 (1990), herein incorporated by reference in their entireties), the promoter for the potato tuber ADPGPP genes, both the large and small subunits; the sucrose synthase promoter (Salanoubat and Belliard, Gene. 60: 47-56 (1987), Salanoubat and Belliard, Gene. 84: 181-185 (1989), herein incorporated by reference in their entirety); and the promoter for the major tuber proteins including the 22 kd protein complexes and proteinase inhibitors (Hannapel, Plant Physiol. 101: 703-704 (1993), herein incorporated by reference in its entirety). Examples of leaf- specific promoters include but are not limited to the ribulose biphosphate carboxylase (RBCS or RuBISCO) promoters (see, e.g., Matsuoka et al, Plant J. 5:311-319 (1994), herein incorporated by reference in its entirety); the light harvesting chlorophyll a/b binding protein gene promoter (see, e.g., Shiina et al, Plant Physiol. 775:477-483 (1997); Casal et al. , Plant Physiol. 775:1533- 1538 (1998), herein incorporated by reference in their entireties); and the Arabidopsis thaliana myb-related gene promoter (Atmyb5) (Li et al, FEBS Lett. 379:111-121 (1996), herein incorporated by reference in its entirety). Examples of root-specific promoter include but are not limited to the promoter for the acid chitinase gene (Samac et al, Plant Mol. Biol. 25: 587-596 (1994), herein incorporated by reference in its entirety); the root specific subdomains of the CaMN35S promoter that have been identified (Lam et al, Proc. Natl. Acad. Sci. (U.S.A.) 55:7890-7894 (1989), herein incorporated by reference in its entirety); the ORF13 promoter from Agrobacterium rhizogenes which exhibits high activity in roots (Hansen et al, Mol. Gen. Genet. 254:331-343 (1997), herein incorporated by reference in its entirety); the promoter for the tobacco root-specific gene RB7 (US Patent 5,750,386; Yamamoto et al, Plant Cell 5:371-382 (1991), herein incorporated by reference in its entirety); and the root cell specific promoters reported by Conkling et al. (Conkling et al, Plant Physiol. 95:1203-1211 (1990), herein incorporated by reference in its entirety). Another class of useful vegetative tissue-specific promoters are meristematic (root tip and shoot apex) promoters. For example, the "SHOOTMERISTEMLESS" and "SCARECROW" promoters, which are active in the developing shoot or root apical meristems (Di Laurenzio et al, Cell 86:423- 433 (1996); Long, Nature 379:66-69 (1996); herein incorporated by reference in their entireties), can be used. Another example of a useful promoter is that which controls the expression of 3-hydroxy-3- methylglutaryl coenzyme A reductase HMG2 gene, whose expression is restricted to meristematic and floral (secretory zone of the stigma, mature pollen grains, gynoecium vascular tissue, and fertilized ovules) tissues (see, e.g., Enjuto et al, Plant Cell. 7:517-527 (1995), herein incorporated by reference in its entirety). Also another example of a useful promoter is that which controls the expression of knl-related genes from maize and other species which show meristem-specific expression (see, e.g., Granger et al, Plant Mol. Biol. 57:373-378 (1996); Kerstetter et al, Plant Cell 5:1877-1887 (1994); Hake et al, Philos. Trans. R. Soc. Lond. B. Biol Sci. 550:45-51 (1995), herein incorporated by reference in their entireties). Another example of a meristematic promoter is the Arabidopsis thaliana KNAT1 promoter. In the shoot apex, KNAT1 transcript is localized primarily to the shoot apical meristem; the expression of KNATI in the shoot meristem decreases during the floral transition and is restricted to the cortex of the inflorescence stem (see, e.g., Lincoln et al. , Plant Cell 6: 1859-1876 (1994), herein incorporated by reference in its entirety). Suitable seed-specific promoters can be derived from the following genes: MAC1 from maize (Sheridan et al, Genetics 142:1009-1020 (1996), herein incorporated by reference in its entirety); Cat3 from maize (GenBank No. L05934, Abler et al, Plant Mol. Biol. 22:10131-1038 (1993), herein incorporated by reference in its entirety); vivparous-1 from Arabidopsis (Genbank No. U93215); Atimycl from Arabidopsis (Urao et al, Plant Mol. Biol. 52:571-57 (1996); Conceicao et al, Plant 5:493-505 (1994), herein incorporated by reference in their entireties); napA from Brassica napus (GenBank No. J02798); the napin gene family from Brassica napus (Sjodahl et al, Planta 197:264-211 (1995), herein incorporated by reference in its entirety).

USA 91:5161-5165 (1994), all of which are herein incorporated by reference in their entireties) can also be used. The egg and central cell specific MEA (FIS1) and FIS2 promoters are also useful reproductive tissue-specific promoters (Luo et al., Proc. Natl. Acad. Sci. USA, 97:10637-10642 (2000); Nielle-Calzada, et al, Genes Dev. 13:2971-2982 (1999); herein incorporated by reference in their entireties). A maize pollen-specific promoter has been identified in maize (Guerrero et al, Mol. Gen. Genet. 224:161-168 (1990), herein incorporated by reference in its entirety). Other genes specifically expressed in pollen have been described (see, e.g., Wakeley et al., Plant Mol. Biol. 37:187-192 (1998); Ficker et al., Mol. Gen. Genet. 257:132-142 (1998); Kulikauskas et al., Plant Mol. Biol. 34:809-814 (1997); Treacy et al., Plant Mol. Biol. 34:603-611 (1997); all of which are herein incorporated by reference in their entireties). Promoters derived from genes encoding embryonic storage proteins, which includes the gene encoding the 2S storage protein from Brassica napus (Dasgupta et al, Gene 133:301-302 (1993), herein incorporated by reference in its entirety); the 2s seed storage protein gene family from Arabidopsis; the gene encoding oleosin 20kD from Brassica napus (GenBank No. M63985); the genes encoding oleosin A (GenBank No. U09118) and oleosin B (GenBank No. U09119) from soybean; the gene encoding oleosin from Arabidopsis (GenBank No. Z17657); the gene encoding oleosin 18kD from maize (GenBank No. J05212, Lee, Plant Mol. Biol. 26:1981-1987 (1994), herein incorporated by reference in its entirety); and the gene encoding low molecular weight sulphur rich protein from soybean (Choi et al, Mol. Gen. Genet. 246:266- 268 (1995), herein incorporated by reference in its entirety), can also be used. Promoters derived from zein encoding genes (including the 15 kD, 16 kD, 19 kD, 22 kD, 27 kD, and gamma genes) (Pedersen et al, Cell 29: 1015-1026 (1982), herein incorporated by reference in its entirety) can be also used. The zeins are a group of storage proteins found in maize endosperm. Other promoters known to function, for example, in maize, include the promoters for the following genes: waxy, Brittle, Shrunken 2, Branching enzymes I and II, starch synthases, debranching enzymes, oleosins, glutelins, and sucrose synthases. A particularly preferred promoter for maize endosperm expression is the promoter for the glutelin gene from rice, more particularly the Osgt-1 promoter (Zheng et al., Mol. Cell Biol. 13: 5829-5842 (1993), herein incorporated by reference in its entirety). Examples of promoters suitable for expression in wheat include those promoters for the ADPglucose pyrophosphorylase (ADPGPP) subunits, the granule bound and other starch synthases, the branching and debranching enzymes, the embryogenesis-abundant proteins, the gliadins, and the glutenins. Examples of such promoters in rice include those promoters for the ADPGPP subunits, the granule bound and other starch synthases, the branching enzymes, the debranching enzymes, sucrose synthases, and the glutelins. A particularly preferred promoter is the promoter for rice glutelin, Osgt-1. Examples of such promoters for barley include those for the ADPGPP subunits, the granule bound and other starch synthases, the branching enzymes, the debranching enzymes, sucrose synthases, the hordeins, the embryo globulins, and the aleurone specific proteins. A tomato promoter active during fruit ripening, senescence and abscission of leaves and, to a lesser extent, of flowers can be used (Blume et al, Plant J. 72:731-746 (1997), herein incorporated by reference in its entirety). Other exemplary promoters include the pistol specific promoter in the potato (Solarium tuberosum L.) SK2 gene, encoding a pistil-specific basic endochitinase (Ficker et al, Plant Mol. Biol. 55:425-431 (1997), herein incorporated by reference in its entirety); the Blec4 gene from pea (Pisum sativum cv. Alaska), active in epidermal tissue of vegetative and floral shoot apices of transgenic alfalfa. This makes it a useful tool to target the expression of foreign genes to the epidermal layer of actively growing shoots. The tissue specific E8 promoter from tomato is also useful for directing gene expression in fruits. It is recognized that additional promoters that may be utilized are described, for example, in U.S. Patent Nos. 5,378,619, 5,391,725, 5,428,147, 5,447,858, 5,608,144, 5,608,144, 5,614,399, 5,633,441, 5,633,435, and 4,633,436, all of which are herein incorporated in their entirety. In addition, a tissue specific enhancer may be used (Fromm et al, The Plant Cell 7:977-984 (1989), herein incorporated by reference in its entirety). It is further recognized that since in most cases the exact boundaries of regulatory sequences have not been completely defined, DNA fragments of different lengths may have identical promoter activity. "For example" means an instance serving to illustrate a precept or to act as an exercise, and is not inclusive of all the possible examples, or embodiments, and acts as only a single representative of a much larger class. "i. e." or "e.g." means in (for) example and can be read as "for example". The "translation leader sequence" means a DNA sequence located between the promoter sequence of a gene and the coding sequence. The translation leader sequence is present in the fully processed mRNA upstream of the translation start sequence. The translation leader sequence may affect processing of the primary transcript to mRNA, mRNA stability or translation efficiency. Examples of translation leader sequences have been described (Turner and Foster, Molecular Biotechnology 5:225 (1995), herein incorporated by reference in its entirety). The "3' non-translated sequences" means DNA sequences located downstream of a structural nucleotide sequence and include sequences encoding polyadenylation and other regulatory signals capable of affecting mRNA processing or gene expression. The polyadenylation signal functions in plants to cause the addition of polyadenylate nucleotides to the 3' end of the mRNA precursor. The polyadenylation sequence can be derived from the natural gene, from a variety of plant genes, or from T-DNA. An example of the polyadenylation sequence is the nopaline synthase 3' sequence (NOS 3'; Fraley et al, Proc. Natl. Acad. Sci. USA 80: 4803-4807 (1983), herein incorporated by reference in its entirety). The use of different 3' non-translated sequences is exemplified by Ingelbrecht et al, Plant Cell 7:671-680 (1989), herein incorporated by reference in its entirety. "Propogule" includes all products of meiosis and mitosis, including but not limited to, seed and parts of the plant able to propogate a new plant. For example, propogule includes a shoot, root, or other plant part that is capable of growing into an entire plant. Propogule also includes grafts where one portion of a plant is grafted to another portion of a different plant (even one of a different species) to create a living organism. Propogule also includes all plants and seeds produced by cloning or by bringing together meiotic products, or allowing meiotic products to come together to form an embryo or fertilized egg (naturally or with human intervention). The isolated nucleic acid molecules of the present invention may also include introns. Generally, optimal expression in monocotyledonous and some dicotyledonous plants is obtained when an intron sequence is inserted between the promoter sequence and the structural gene sequence or, optionally, may be inserted in the structural coding sequence to provide an interrupted coding sequence. An example of such an intron sequence is the HSP 70 intron described in WO 93/19189, herein incorporated by reference in its entirety. The laboratory procedures in recombinant DNA technology used herein are those well known and commonly employed in the art. Standard techniques are used for cloning, DNA and RNA isolation, amplification and purification. Generally enzymatic reactions involving DNA ligase, DNA polymerase, restriction endonucleases and the like are performed according to the manufacturer's specifications. These techniques and various other techniques are generally performed according to Sambrook et al., Molecular Cloning - A Laboratory Manual, 2nd. ed., Cold Spring Harbor Laboratory, Cold Spring Harbor, New York (1989). Another aspect of the present invention relates to an isolated nucleic acid molecule having a nucleotide sequence selected from the group consisting of SEQ ID NOS: 1, 3, 5, 7, 8, 10, and 12 or complements thereof, that contains DNA markers. DNA markers of the present invention include "dominant" or "codominant" markers. "Codominant markers" reveal the presence of two or more alleles (two per diploid individual) at a locus. "Dominant markers" reveal the presence of only a single allele per locus. The presence of the dominant marker phenotype (e.g., a band of DNA) is an indication that one allele is present in either the homozygous or heterozygous condition. The absence of the dominant marker phenotype (e.g. absence of a DNA band) is merely evidence that "some other" undefined allele is present. In the case of populations where individuals are predominantly homozygous and loci are predominately dimorphic, dominant and codominant markers can be equally valuable. As populations become more heterozygous and muti-allelic, codominant markers often become more informative of the genotype than dominant markers. Examples of DNA markers include restriction fragment length polymorphism (RFLP), random amplified fragment length polymorphism (RAPD), simple sequence repeat polymorphism (SSR), cleavable amplified polymorphic sequences (CAPS), amplified fragment length polymorphism (AFLP), and single nucleotide polymorphism (SNP). DNA markers can be developed from nucleic acid molecules using restriction endonucleases, the PCR and/or DNA sequence information. Methods for isolating DNA markers are well known in the art (see for example, Birren and Lai, Nonmammalian Genomic Analysis, Academic Press, Inc, San Diego, California, USA; London, England, UK, pp. 75-134 (1996); Brown et al, Methods of Genome Analysis in Plants, ed. Jauhar, CRC Press, Inc,. Boca Raton, Florida, USA; London, England, UK (1996), both of which are herein incorporated by reference in their entirety). RFLP markers are codominant and highly abundant in plant genomes and have a medium level of polymorphism. RFLP is resulted from single base changes or insertions/deletions. The RFLP markers can be developed by a combination of restriction endonuclease digestion and Southern blotting hybridization. CAPSs are codominant markers and highly abundant in plant genomes and have a medium level of polymorphism. CAPS is resulted from single base changes and insertions/deletions. The CAPs markers can be developed from restriction endonuclease digestion of PCR products. RAPDs are dominant markers and very highly abundant in plant genomes and have a medium level of polymorphism. RAPD is result from single base changes and insertions and deletions in plant genomes. The RAPDs markers can be developed from DNA amplification with random primers. AFLP markers are both dominant and codominant. They are highly abundant in plant genomes and exhibit a medium level of polymorphism. AFLP is resulted from single base changes, insertions, and deletions. The AFLP markers can be developed by PCR of a subset of restriction fragments from extended adapter primers. SSR is resulted from repeat length changes. SSR markers are codominant and exhibit a medium degree of abundance in plant genomes and a high level of polymorphism. On average, 1 SSR is found every 21 and 65 kb in dicots and monocots. Fewer CG nucleotides are found in dicots than in monocots. There is no correlation between abundance of SSRs and nuclear DNA content. The abundance of all tri and tetranucleotide SSR combination jointly have been reported to be equivalent to that of the total di-nucleotide combinations. Mono- di- and tetra-nucleotide repeats are all located in noncoding regions of DNA while 57% of those trinucleotide SSRs containing CG were located within gene coding regions. All repeated trinucleotide SSRs composed entirely of AT are found in noncoding regions, (Brown et al, Methods of Genome Analysis in Plants, ed. Jauhar, CRC Press, Inc, Boca Raton, Florida, USA; London, England, UK, pp. 147-159, (1996)). The development of SSRs requires DNA sequence information. SSRs can be identified in SEQ NOS: 1, 3, 5, 7, 8, 10, and 12 or complements thereof by using the BLASTN program to examine sequences for the presence/absence of SSRs. SNP is resulted from single base changes. They are highly abundant and exhibit a myriad of polymorphism (Rafalski, et al, In: Nonmammalian Genomic Analysis, ed. Birren and Lai, Academic Press, San Diego, CA, pp. 75-134 (1996), the entirety of which is herein incorporated by reference). Development of SNPs also requires DNA sequence information. Isolation and identification of nucleic acid molecules encoding ^ 4NE-like polypeptides from soybean, corn, rice and cotton are described in detail in Examples. All or a substantial portion of the nucleic acid molecules of the present invention may be used to isolate cDΝAs and nucleic acid molecules encoding homologous polypeptides from the same or other plant species. A "substantial portion" of a nucleotide sequence comprises enough of the sequence to afford specific identification and/or isolation of a nucleic acid molecule comprising the sequence. Nucleotide sequences can be evaluated either manually by one skilled in the art, or by using computer based sequence comparison and identification tools that employ algorithms such as BLAST (Basic Local Alignment Search Tool; Altschul et al. JMol Biol. 275:403-410 (1993); see also www.ncbi.nlm.nih.gov/BLAST/). In general, a sequence of thirty or more contiguous nucleotides is necessary in order to putatively identify a nucleotide sequence as homologous to a gene. Moreover, with respect to nucleotide sequences, gene-specific oligonucleotide probes comprising 30 or more contiguous nucleotides may be used in sequence-dependent methods of gene identification (e.g., Southern hybridization) and isolation (e.g., in situ hybridization of bacterial colonies or bacteriophage plaques). In addition, short oligonucleotides of 12 or more nucleotides may be used as amplification primers in PCR in order to obtain a particular nucleic acid molecule comprising the primers. The skilled artisan, having the benefit of the sequences as reported herein, may now use all or a substantial portion of the disclosed sequences for purposes known to those skilled in this art. Accordingly, the instant invention comprises the complete sequences as reported in the accompanying Sequence Listing, as well as substantial portions of those sequences as defined above. Isolation of nucleic acid molecules encoding homologous polypeptides using sequence- dependent protocols is well known in the art. Examples of sequence-dependent protocols include, but are not limited to, methods of nucleic acid molecule hybridization, and methods of DNA and RNA amplification as exemplified by various uses of nucleic acid molecule amplification technologies (e.g., polymerase chain reaction, ligase chain reaction). For example, structural nucleic acid molecules encoding other ANT-like polypeptide, either as cDNAs or genomic DNAs, could be isolated directly by using all or a substantial portion of the nucleic acid molecules of the present invention as DNA hybridization probes to screen cDNA or genomic libraries from any desired plant employing methodology well known to those skilled in the art. Methods for forming such libraries are well known in the art. Specific oligonucleotide probes based upon the nucleic acid molecules of the present invention can be designed and synthesized by methods known in the art. Moreover, the entire sequences of the nucleic acid molecules can be used directly to synthesize DNA probes by methods known to the skilled artisan such as random primer DNA labeling, nick translation, or end-labeling techniques, or RNA probes using available in vitro transcription systems. In addition, specific primers can be designed and used to amplify a part or all of the sequences. The resulting amplification products can be labeled directly during amplification reactions or labeled after amplification reactions, and used as probes to isolate full length cDNA or genomic DNAs under conditions of appropriate stringency. Alternatively, the nucleic acid molecules of interest can be amplified from nucleic acid samples using amplification techniques. For instance, the disclosed nucleic acid molecules may be used to define a pair of primers that can be used with the polymerase chain reaction (Mullis, et al, Cold Spring Harbor Symp. Quant. Biol. 57:263-273 (1986); Erlich et al, EP 50,424; EP 84,796, EP 258,017, EP 237,362; Mullis, EP 201,184;, Mullis et al, US 4,683,202; Erlich, US 4,582,788; and Saiki, R. et al, US 4,683,194, all of which are herein incorporated by reference in their entireties) to amplify and obtain any desired nucleic acid molecule directly from mRNA, from cDNA, from genomic libraries or cDNA libraries. PCR and other in vitro amplification methods may also be useful, for example, to clone nucleotide sequences that encode for polypeptides to be expressed, to make nucleic acid molecules to use as probes for detecting the presence of the desired mRNA in samples, for nucleic acid sequencing, or for other purposes. In addition, two short segments of the nucleic acid molecules of the present invention may be used in polymerase chain reaction protocols to amplify longer nucleic acid molecules encoding homologues of an ._4NE-like polypeptide from DΝA or R A. For example, the skilled artisan can follow the RACE protocol (Frohman et al., Proc. Νatl. Acad. Sci. USA 85:8998 (1988), herein incorporated by reference in its entirety) to generate cDΝAs by using PCR to amplify copies of the region between a single point in the transcript and the 3' or 5' end. Primers oriented in the 3' and 5' directions can be designed from the nucleic acid molecules of the present invention. Using commercially available 3 'RACE or 5 'RACE systems (Gibco BRL, Life Technologies, Gaithersburg, Maryland U.S.A.), specific 3' or 5' cDΝA fragments can be isolated (Ohara et al., Proc. Νatl. Acad. Sci. USA 86:5673 (1989); Loh et al., Science 243:217 (1989), both of which are herein incorporated by reference in their entireties). Products generated by the 3' and 5' RACE procedures can be combined to generate full-length cDΝAs (Frohman and Martin, Techniques 1: 165 (1989), herein incorporated by reference in its entirety). Nucleic acid molecules of interest may also be synthesized, either completely or in part, especially where it is desirable to provide plant-preferred sequences, by well-known techniques as described in the technical literature. See, e.g., Carruthers et al., Cold Spring Harbor Symp. Quant. Biol. 47:411-418 (1982), and Adams et al., J. Am. Chem. Soc. 105:661 (1983), both of which are herein incorporated by reference in their entireties. Thus, all or a portion of the nucleic acid molecules of the present invention may be synthesized using codons preferred by a selected plant host. Plant-preferred codons may be determined, for example, from the codons used most frequently in the proteins expressed in a particular plant host species. Other modifications of the gene sequences may result in mutants having slightly altered activity. Availability of the nucleotide sequences encoding ^ 4NE-like polypeptides facilitates immunological screening of cDΝA expression libraries. Synthetic polypeptides representing portions of the amino acid sequences of v4NE-like polypeptides may be synthesized. These polypeptides can be used to immunize animals to produce polyclonal or monoclonal antibodies with specificity for polypeptides comprising the amino acid sequences. These antibodies can be then be used to screen cDΝA expression libraries to isolate full-length cDΝA clones of interest (Lemer, Adv. Immunol. 36: 1 (1984); Sambrook et al., Molecular Cloning: A Laboratory Manual; Cold Spring Harbor Laboratory Press: Cold Spring Harbor, (1989)). It is understood that people skilled in the art are familiar with the standard resource materials which describe specific conditions and procedures for the construction, manipulation and isolation of antibodies (see, for example, Harlow and Lane, In Antibodies: A Laboratory Manual, Cold Spring Harbor Press, Cold Spring Harbor, New York (1988)). Another aspect of the present invention relates to methods for obtaining a nucleic acid molecule comprising a nucleotide sequence encoding an ^ 4NE-like polypeptide the amino acid sequence of which has at least 60% sequence identity to a member selected from the group consisting of SΕQ ID Νos: 2, 4, 6, 9, 11, and 13. One method of the present invention for obtaining a nucleic acid molecule encoding all or a substantial portion of the amino acid sequence of an ^ 4NE-like polypeptide comprising: (a) probing a cDΝA or genomic library with a hybridization probe comprising a nucleotide sequence encoding all or a substantial portion of a polypeptide having an amino acid sequence set forth in any of SΕQ ID Νos: 2, 4, 6, 9, 11, and 13 or an amino acid sequence set forth in any of SΕQ ID Νos: 2, 4, 6, 9, 11, and 13 with conservative amino acid substitutions; (b) identifying a DΝA clone that hybridizes under stringent conditions to the hybridization probe; (c) isolating the DΝA clone identified in step (b); and (d) sequencing the cDΝA or genomic fragment that comprises the clone isolated in step (c) wherein the sequenced nucleic acid molecule encodes all or a substantial portion of the amino acid sequence of the v4NE-like polypeptide. Another method of the present invention for obtaining a nucleic acid molecule encoding all or a substantial portion of the amino acid sequence of an ANT-like polypeptide comprising: (a) synthesizing a first and a second oligonucleotide primers, wherein the sequences of the first and second oligonucleotide primers encode two different portions of a polypeptide having an amino acid sequence selected from the group consisting of SEQ ID Nos: 2, 4, 6, 9, 11, and 13; and (b) amplifying and obtaining the nucleic acid molecule directly from mRNA samples, from genomic libraries or from cDNA libraries using the first and second oligonucleotide primers of step (a) wherein the nucleic acid molecule encodes all or a substantial portion of the amino acid sequence of the ^ 4NE-like polypeptide. The isolated nucleic acid molecules of the present invention can also be used in antisense technology to suppress endogenous ANT-like gene expression. To accomplish this, a nucleic acid molecule derived from a nucleotide sequence selected from the group consisting of SΕQ ID NO: 1, 3, 5, 7, 8, 10, and 12 is cloned and operably linked to a promoter such that the antisense strand of RNA will be transcribed. The construct is then transformed into plants and the antisense strand of RNA is produced. In plant cells, it has been suggested that antisense RNA inhibits gene expression by preventing the accumulation of mRNA which encodes the enzyme of interest (see, e.g., Sheehy et al, Proc. Nat. Acad. Sci. USA 55:8805-8809 (1988), and U.S. Patent No. 4,801,340; both of which are herein incorporated by reference in their entireties). The nucleic acid segment to be introduced generally will be substantially identical to at least a portion of the endogenous ^ 4NE-like gene or genes to be repressed. The sequence, however, need not be perfectly identical to inhibit expression. The recombinant vectors of the present invention can be designed such that the inhibitory effect applies to other genes within a family of genes exhibiting homology or substantial homology to the target gene. For antisense suppression, the introduced sequence also need not be full length relative to either the primary transcription product or fully processed mRΝA. Generally, higher homology can be used to compensate for the use of a shorter sequence. Furthermore, the introduced sequence need not have the same intron or exon pattern, and homology of non-coding segments may he equally effective. Normally, a sequence of between about 30 or 40 nucleotides and about full length nucleotides should be used, though a sequence of at least about 100 nucleotides is preferred, a sequence of at least about 200 nucleotides is more preferred, and a sequence of about 500 to about 1700 nucleotides is especially preferred. Catalytic RNA molecules or ribozymes can also be used to inhibit expression of ^ 4NE-like genes. It is possible to design ribozymes that specifically pair with virtually any target RΝA and cleave the phosphodiester backbone at a specific location, thereby functionally inactivating the target RΝA. In carrying out this cleavage, the ribozyme is not itself altered, and is thus capable of recycling and cleaving other molecules, making it a true enzyme. The inclusion of ribozyme sequences within antisense RΝAs confers RΝA-cleaving activity upon them, thereby increasing the activity of the recombinant DΝA constructs. A number of classes of ribozymes have been identified. One class of ribozymes is derived from a number of small circular RΝAs which are capable of self-cleavage and replication in plants. The RΝAs replicate either alone (viroid RΝAs) or with a helper virus (satellite RΝAs). Examples include RΝAs from avocado sunblotch viroid and the satellite RΝAs from tobacco ringspot virus, lucerne transient streak virus, velvet tobacco mottle virus, Solanum nodiflorum mottle virus and subterranean clover mottle virus. The design and use of target RΝA- specific ribozymes is described in Haseloff et al. Nature 334:585-591 (1988), herein incorporated by reference in its entirety. The isolated nucleic acid molecules of the present invention can also be used in sense cosuppression to modulate expression of endogenous v4NE-like genes. The suppressive effect may occur where the introduced sequence contains no coding sequence per se, but only intron or untranslated sequences homologous to sequences present in the primary transcript of the endogenous sequence. The introduced sequence generally will be substantially identical to the endogenous sequence intended to be repressed. This minimal identity will typically be greater than about 65 %, but a higher identity might exert a more effective repression of expression of the endogenous sequences. Substantially greater identity of more than about 80% is preferred, though about 95% to absolute identity would be most preferred. As with antisense regulation, the effect should apply to any other proteins within a similar family of genes exhibiting homology or substantial homology. For sense suppression, the introduced sequence, needing less than absolute identity, also need not be full length, relative to either the primary transcription product or fully processed mRNA. This may be preferred to avoid concurrent production of some plants which are overexpressed. A higher identity in a shorter than full length sequence compensates for a longer, less identical sequence. Furthermore, the introduced sequence need not have the same intron or exon pattern, and identity of non-coding segments will be equally effective. Normally, a sequence of the size ranges noted above for antisense regulation is used. Changes in plant phenotypes can be produced by specifically inhibiting expression of one or more genes by antisense inhibition or cosuppression (U.S. Patent Nos. 5,190,931, 5,107,065 and 5,283,323, herein incorporated by reference in their entireties). An antisense or cosuppression construct would act as a dominant negative regulator of gene activity. While conventional mutations can yield negative regulation of gene activity, these effects are most likely recessive. The dominant negative regulation available with a transgenic approach may be advantageous from a breeding perspective. In addition, the ability to restrict the expression of specific phenotype to the reproductive tissues of the plant by the use of tissue specific promoters may confer agronomic advantages relative to conventional mutations which may have an effect in all tissues in which a mutant gene is ordinarily expressed. The person skilled in the art will know that special considerations are associated with the use of antisense or cosuppression technologies in order to reduce expression of particular genes. For example, the proper level of expression of sense or antisense genes may require the use of different chimeric genes utilizing different regulatory elements known to the skilled artisan. Once transgenic plants are obtained by one of the methods described above, it will be necessary to screen individual transgenic plants for those that most effectively display the desired phenotype. Accordingly, the skilled artisan will develop methods for screening large numbers of transformants. The nature of these screens will generally be chosen on practical grounds, and is not an inherent part of the invention. For example, one can screen by looking for changes in gene expression by using antibodies specific for the polypeptide encoded by the gene being suppressed, or one could establish assays that specifically measure enzyme activity. A preferred method will be one which allows large numbers of samples to be processed rapidly, since it will be expected that a large number of transformants will be negative for the desired phenotype. All or a substantial portion of the nucleic acid molecules of the present invention may also be used as probes for genetically and physically mapping the genes that they are a part of, and as markers for traits linked to those genes. Such information may be useful in plant breeding in order to develop lines with desired phenotypes. For example, the nucleic acid molecules of the present invention may be used as restriction fragment length polymorphism (RFLP) markers. Southern blots (Maniatis et al., Molecular Cloning: A Laboratory Manual, Second Edition (1989) Cold Spring Harbor Laboratory, Cold Spring Harbor, NN., herein incorporated by reference in its entirety) of restriction-digested plant genomic DΝA may be probed with the nucleic acid fragments of the present invention. The resulting banding patterns may then be subjected to genetic analyses using computer programs such as MapMaker (Lander et al, Genomics 7:174- 181 (1987), herein incorporated by reference in its entirety) in order to construct a genetic map. In addition, the nucleic acid fragments of the present invention may be used to probe Southern blots containing restriction endonuclease-treated genomic DΝAs of a set of individuals representing parent and progeny of a defined genetic cross. Segregation of the DΝA polymorphisms is noted and used to calculate the position of the nucleotide sequence of the present invention in the genetic map previously obtained using this population (Botstein et al, Am. J. Hum. Genet. 52:314-331 (1980), herein incorporated by reference in its entirety). The production and use of plant gene-derived probes for use in genetic mapping is described in Bernatzky and Tanksley, Plant Mol. Biol. Reporter 4:31-41 (1986), herein incorporated by reference in its entirety. Numerous publications describe genetic mapping of specific cDNA clones using the methodology outlined above or variations thereof. For example, F2 intercross populations, backcross populations, randomly mated populations, near isogenic lines, exotic germplasms, and other sets of individuals may be used for mapping. Such methodologies are well known to those skilled in the art. Nucleic acid probes derived from the nucleic acid molecules of the present invention may also be used for physical mapping (i.e., placement of sequences on physical maps; see Hoheisel et al, In: Nonmammalian Genomic Analysis: A Practical Guide, Academic press 1996, pp. 319- 346, and references cited therein). In another embodiment, nucleic acid probes derived from the nucleic acid molecules of the present invention may be used in direct fluorescence in situ hybridization (FISH) mapping (Trask, Trends Genet. 7:149-154 (1991), herein incorporated by reference in its entirety). Although current methods of FISH mapping favor use of large clones (several to several hundred KB; see Laan et al, Genome Res. 5:13-20 (1995), herein incorporated by reference in its entirety), improvements in sensitivity may allow performance of FISH mapping using shorter probes. A variety of nucleic acid amplification-based methods of genetic and physical mapping may be carried out using the nucleotide molecules of the present invention. Examples include allele-specific amplification (Kazazian et al., J. Lab. Clin. Med. 77:95-96 (1989), herein incorporated by reference in its entirety), polymorphism of PCR-amplified fragments (CAPS; Sheffield et al, Genomics 75:325-332 (1993), herein incorporated by reference in its entirety), allele-specific ligation (Landegren et al, Science 2^7:1077-1080 (1988) herein incorporated by reference in its entirety), nucleotide extension reactions (Sokolov et al., Nucleic Acid Res. 75:3671 (1990) herein incorporated by reference in its entirety), Radiation Hybrid Mapping (Walter et al, Nat. Genet. 7:22-28 (1997) herein incorporated by reference in its entirety) and Happy Mapping (Dear and Cook, Nucleic Acid Res. 17:6195-6801 (1989) herein incorporated by reference in its entirety). For these methods, the sequence of a nucleic acid fragment is used to design and produce primer pairs for use in the amplification reaction or in primer extension reactions. The design of such primers is well known to those skilled in the art. In methods employing PCR-based genetic mapping, it may be necessary to identify DNA sequence differences between the parents of the mapping cross in the region corresponding to the nucleotide sequence. This, however, is generally not necessary for mapping methods. Isolated nucleic acid molecules of the present invention may find use in the identification of loss of function mutant phenotypes of a plant, due to a mutation in one or more endogenous genes encoding the ANT-like polypeptides. This can be accomplished either by using targeted gene disruption protocols or by identifying specific mutants for these genes contained in a population of plants carrying mutations in all possible genes (Ballinger and Benzer, Proc. Natl. Acad Sci USA 55:9402-9406 (1989); Koes et al, Proc. Natl. Acad. Sci. USA 92:8149-8153 (1995); Bensen et al, Plant Cell 7:75-84 (1995) all of which are incorporated herein by reference in their entirety). The latter approach may be accomplished in two ways. First, short segments of the nucleic acid molecules of the present invention may be used in polymerase chain reaction protocols in conjunction with a mutation tag sequence primer on DNAs prepared from a population of plants in which mutator transposons or some other mutation-causing DNA element has been introduced. The amplification of a specific DNA fragment with these primers indicates the insertion of the mutation tag element in or near the plant gene encoding ^ 4NE-like polypeptides. Alternatively, the nucleic acid molecules of the present invention may be used as a hybridization probe against PCR amplification products generated from the mutation population using the mutation tag sequence primer in conjunction with an arbitrary genomic site primer, such as that for a restriction enzyme site-anchored synthetic adapter. With either method, a plant containing a mutation in the endogenous gene encoding the ^NT-like polypeptides can be identified and obtained. This mutant plant can then be used to determine or confirm the natural function of the ANT-like polypeptides disclosed herein. Methods for introducing genetic mutations into plant genes are well known. For instance, seeds or other plant material can be treated with a mutagenic chemical substance, according to standard techniques. Such chemical substances include, but are not limited to, the following: diethyl sulfate, ethylene imine, ethyl methanesulfonate and Ν-nitroso-Ν-ethylurea. Alternatively, ionizing radiation from sources such as, for example, X-rays or gamma rays can be used. Desired mutants are selected by assaying for increased seed mass, oil content and other properties. Methods for determining gene expression, even expression of a gene from an introduced transgene are common in the art, and include RT-PCR, Northern blots, and Taqman®. Taqman® (PΕ Applied Biosystems, Foster City, CA) is described as a method of detecting and quantifying the presence of a DNA or RNA/cDNA molecule and is fully described in the instructions provided by the manufacturer, and at their website. Briefly, in the case of a genomic sequence a FRET oligonucleotide probe is designed which overlaps the genomic flanking and insert DNA junction. The FRET probe and PCR primers (one primer in the insert DNA sequence and one in the flanking genomic sequence) are cycled in the presence of a thermostable polymerase and dNTPs. Hybridization of the FRET probe results in cleavage and release of the fluorescent moiety away from the quenching moiety on the FRET probe. A fluorescent signal indicates the presence of the flanking/transgene insert DNA due to successful amplification and hybridization. Substantially Purified Polypeptides The present invention, in another aspect, provides a substantially purified polypeptide the amino acid sequence of which comprises in the N-terminal to C-terminal direction two AP2 DNA binding domains followed in the C-terminal by an amino acid subsequence selected from group consisting of Xaa-Ser-Ser-Ser-Arg-Glu, Xaa-Ser-Asn-Ser-Arg-Glu, and Asn-Ser-Ser-Ser- Arg-Asn, preferably selected from the group consisting of Ser-Ser-Leu-Xaa-Thr-Ser-Xaa-Ser- Ser-Ser-Arg-Glu, Ser-Ser-Leu-Xaa-Pro-Ser-Xaa-Ser-Asn-Ser-Arg-Glu, Ser-Ser-Leu-Xaa-Thr- Ser-Xaa-Ser-Asn-Ser-Arg-Glu, and Ser-Leu-Xaa-Asn-Ser-Ser-Ser-Arg-Asn wherein Xaa is an amino acid residue having an aliphatic side chain and selected from the group consisting of Gly, Ala, Nal, Leu, and He. In a particular preferred embodiment, the substantially purified polypeptide of the present invention further comprises a second amino acid subsequence selected from the group consisting of Leu-Gly-Phe-Ser-Leu-Ser, Leu-Gly-Phe-Ser-Leu-Thr, Met-Pro- Leu-Lys-Ser-Asp-Gly-Ser, Met-Pro-Leu-Arg-Ser-Asp-Gly-Ser, Met-Pro-Ile-Lys-Ser-Asp-Gly- Ser, Pro-Lys-Leu-Glu-Asp-Phe, and Pro-Lys-Val-Glu-Asp-Phe. In some groups of amino acids, the side chains are described as having aliphatic side chains. Aliphatic side chains are often designated as a side chain of organic chemical compounds in which the carbon atoms are linked in open chains, for example Gly, Ala, Val, Leu, and He. The present invention, in another aspect, provides a substantially purified polypeptide the amino acid sequence of which is encoded by a first nucleotide sequence which specifically hybridizes under stringent conditions to the complement of a second nucleotide sequence selected from the groups consisting of SEQ ID NO: 1, 3, 5, 7, 8, 10, and 12. The present invention, in another aspect, provides a substantially purified polypeptide the amino acid sequence of which is encoded by a nucleotide sequence that has at least 60% sequence identity, preferably at least 70% or 75% sequence identity, more preferably at least 80%) or 85%o sequence identity, even more preferably at least 90% or 95%) sequence identity, most preferably at least 98%> sequence identity to a member selected from the group consisting of SEQ ID NOs: 1, 3, 5, 7, 8, 10, and 12. The present invention, in another aspect, provides a substantially purified polypeptide the amino acid sequence of which has at least 60% sequence identity, preferably at least 70% or 75%) sequence identity, more preferably at least 80% or 85%> sequence identity, even more preferably at least 90% or 95% sequence identity, and most preferably at least 98% sequence identity to a sequence selected from the group consisting of SEQ ID Nos: 2, 4, 6, 9, 11, and 13. The polypeptides of the present invention may be produced via chemical synthesis, or more preferably, by expression in a suitable bacterial or eukaryotic host. Suitable methods for expression are described by Sambrook, et al , (In: Molecular Cloning, A Laboratory Manual, 2nd Edition, Cold Spring Harbor Press, Cold Spring Harbor, New York (1989)), herein incorporated by reference in its entirety), or similar texts. The polypeptides of the present invention may also include fusion polypeptides. A polypeptide that comprises one or more additional polypeptide regions not derived from that polypeptide is a "fusion" polypeptide. Such molecules may be derivatized to contain carbohydrate or other moieties (such as keyhole limpet hemocyanin, etc.). Fusion polypeptide of the present invention are preferably produced via recombinant means. The polypeptide molecules of the present invention may also include polypeptides encoded by all or a substantial portion of polypeptide-encoding sequences set forth in SEQ ID NOs: 1, 3, 5, 7, 8, 10, and 12 or complements thereof or, fragments or fusions thereof in which conservative, non-essential, or not relevant, amino acid residues have been added, replaced, or deleted. An example of such a homologue is the homologue polypeptide (or protein) from different species. Such a homologue can be obtained by any of a variety of methods. For example, as indicated above, one or more of the disclosed sequences (all or a substantial portion of a polypeptide-encoding sequences selected from the group consisting of SEQ ID NOs: 1 , 3, 5, 7, 8, 10, and 12 and complements thereof) will be used to define a pair of primers that may be used to isolate the homologue-encoding nucleic acid molecules from any desired species. Such molecules can be expressed to yield homologues by recombinant means. Another aspect of the present invention provides antibodies, single-chain antigen binding molecules, or other proteins that specifically bind to the polypeptides of the present invention and their homologues, fusions or fragments thereof. Such antibodies may be used to quantitatively or qualitatively detect the polypeptides of the present invention. As used herein, an antibody is said to "specifically bind" to a polypeptide molecule of the present invention if such binding is not competitively inhibited by the presence of non-related molecules. The antibodies that specifically bind the polypeptides of the present invention may be polyclonal or monoclonal, and may comprise intact immunoglobulins, or antigen binding portions of immunoglobulins (such as (F(ab'), F(ab')2) fragments, or single-chain immunoglobulins producible, for example, via recombinant means). It is understood that practitioners are familiar with the standard resource materials which describe specific conditions and procedures for the construction, manipulation and isolation of antibodies (see, for example, Harlow and Lane, In Antibodies: A Laboratory Manual, Cold Spring Harbor Press, Cold Spring Harbor, New York (1988), the entirety of which is herein incorporated by reference). Nucleic acid molecules that encode all or part of the ANT-like polypeptides of the present invention can be expressed, via recombinant means, to yield polypeptides that can in turn be used to elicit antibodies that are capable of binding the expressed polypeptides. It may be desirable to derivatize the obtained antibodies, for example with a ligand group (such as biotin) or a detectable marker group (such as a fluorescent group, a radioisotope or an enzyme). Such antibodies may be used in immunoassays for that polypeptide. In a preferred embodiment, such antibodies can be used to screen cDNA expression libraries to isolate full-length cDNA clones of ^ 4NE-like genes (Lemer, Adv. Immunol. 36: 1 (1984); Sambrook et al., Molecular Cloning: A Laboratory Manual; Cold Spring Harbor Laboratory Press: Cold Spring Harbor, (1989)). Plant Recombinant DΝA Constructs and Transformed Plants The isolated nucleic acid molecules of the present invention can find particular use in creating transgenic plants in which ANT or ^NE-like polypeptides are overexpressed. Overexpression of ANT or ANT-like polypeptides in a plant can increase the size of plant organs, e.g., seeds, fruits, roots, tubers, stems, bulbs and leaves, and thereby lead to improvement in the yield of the plant. It would also be desirable to produce a plant by the overexpression of ANT or ANT-like polypeptides that is itself larger, for example increased height and/or size. It will be particularly desirable to increase seed size, seed proteins, seed oils, and seed carbohydrates in crop plants in which seed are used directly for animal or human consumption or for industrial purposes. Examples of such crops include soybean, canola, rape, cotton (cottonseeds), sunflower, and grains such as corn, wheat, rice, rye, and the like. The term "transgenic plant" means a plant that contains an exogenous nucleic acid, which can be derived from the same plant species or from a different species. By "exogenous" it is meant that a nucleic acid molecule originates from outside the plant which the nucleic acid molecule is introduced. An exogenous nucleic acid molecule can have a naturally occurring or non-naturally occurring nucleotide sequence. One skilled in the art understands that an exogenous nucleic acid molecule can be a heterologous nucleic acid molecule derived from a different plant species than the plant into which the nucleic acid molecule is introduced or can be a nucleic acid molecule derived from the same plant species as the plant into which it is introduced. Plant cell, as used herein, includes without limitation, seeds suspension cultures, embryos, meristematic regions, callus tissue, leaves, roots, shoots, gametophytes, sporophytes, pollen and microspores. The term "genome" as it applies to plant cells encompasses not only chromosomal DNA found within the nucleus, but organelle DNA found within subcellular components of the cell. DNAs of the present invention introduced into plant cells can therefore be either chromosomally integrated or organelle-localized. The term "genome" as it applies to bacteria encompasses both the chromosome and plasmids within a bacterial host cell. Encoding DNAs of the present invention introduced into bacterial host cells can therefore be either chromosomally integrated or plasmid-localized. Exogenous nucleic acid molecules may be transferred into a plant cell by the use of a recombinant DNA construct (or vector) designed for such a purpose. The present invention also provides a plant recombinant DNA construct (or vector) for producing transgenic plants, wherein the plant recombinant DNA construct (or vector) comprises a structural nucleotide sequence encoding an ^ 4NE-like polypeptide. Method which are well known to those skilled in the art may be used to prepare the plant recombinant DΝA construct (or vector) of the present invention. These method include in vitro recombinant DΝA techniques, synthetic techniques, and in vivo genetic recombination. Such techniques are described in Sambrook et al., Molecular Cloning, A Laboratory Manual, Cold Spring Harbor Press, Plainview, Ν.Y. (1989); and Ausubel et al., Current Protocols in Molecular Biology, John Wiley & Sons, New York, N.Y. (1989). A plant recombinant DNA construct (or vector) of the present invention contains a structural nucleotide sequence encoding an NE-like polypeptide of the present invention and operably linked regulatory sequences or control elements. Exemplary regulatory sequences include but are not limited to promoters, translation leader sequences, introns, 3' non-translated sequences. The promoters can be constitutive, inducible, or tissue-specific promoters. A plant recombinant DΝA construct (vector) of the present invention will typically comprise a selectable marker which confers a selectable phenotype on plant cells. Selectable markers may also be used to select for plants or plant cells that contain the exogenous nucleic acid molecules encoding polypeptides of the present invention. The marker may encode biocide resistance, antibiotic resistance (e.g., kanamycin, G418 bleomycin, hygromycin, etc.), or herbicide resistance (e.g., glyphosate, etc.). Examples of selectable markers include, but are not limited to, a neo gene (Potrykus et al., Mol. Gen. Genet. 799:183-188 (1985)) which codes for kanamycin resistance and can be selected for using kanamycin, G418, etc.; a bar gene which codes for bialaphos resistance; a mutant EPSP synthase gene (Hinchee et al, Bio/Technology 5:915-922 (1988)) which encodes glyphosate resistance; a nitrilase gene which confers resistance to bromoxynil (Stalker et al., J. Biol. Chem. 255:6310-6314 (1988)); a mutant acetolactate synthase gene (ALS) which confers imidazolinone or sulphonylurea resistance (European Patent Application 154,204 (Sept. 11, 1985)); and a methotrexate resistant DHFR gene (Thillet et al, J. Biol Chem. 255:12500-12508 (1988)). A plant recombinant DNA construct (vector) of the present invention may also include a screenable marker. Screenable markers may be used to monitor expression. Exemplary screenable markers include a β-glucuronidase or uidA gene (GUS) which encodes an enzyme for which various chromogenic substrates are known (Jefferson, Plant Mol. Biol, Rep. 5:387-405 (1987); Jefferson et al, EMBO J. 5:3901-3907 (1987)); an R-locus gene, which encodes a product that regulates the production of anthocyanin pigments (red color) in plant tissues (Dellaporta et al, Stadler Symposium 77:263-282 (1988)); a β-lactamase gene (Sutcliffe et al, Proc. Natl. Acad. Sci. (U.S.A.) 75:3737-3741 (1978)), a gene which encodes an enzyme for which various chromogenic substrates are known (e.g., PAD AC, a chromogenic cephalosporin); a luciferase gene (Ow et al, Science 254:856-859 (1986)) a xylE gene (Zukowsky et al, Proc. Natl. Acad. Sci. (U.S.A.) 50:1101-1105 (1983)) which encodes a catechol dioxygenase that can convert chromogenic catechols; an α-amylase gene (Ikatu et al, Bio/Technol 5:241-242 (1990)); a tyrosinase gene (Katz et al., J. Gen. Microbiol. 729:2703-2714 (1983)) which encodes an enzyme capable of oxidizing tyrosine to DOPA and dopaquinone which in turn condenses to melanin; an α-galactosidase, which will turn a chromogenic α-galactose substrate. Included within the terms "selectable or screenable marker genes" are also genes which encode a secretable marker whose secretion can be detected as a means of identifying or selecting for transformed cells. Examples include markers which encode a secretable antigen that can be identified by antibody interaction, or even secretable enzymes which can be detected catalytically. Secretable proteins fall into a number of classes, including small, diffusible proteins detectable, e.g., by ELISA, small active enzymes detectable in extracellular solution {e.g., α-amylase, β-lactamase, phosphinothricin transferase), or proteins which are inserted or trapped in the cell wall (such as proteins which include a leader sequence such as that found in the expression unit of extension or tobacco PR-S). Other possible selectable and/or screenable marker genes will be apparent to those of skill in the art. In addition to a selectable marker, it may be desirous to use a reporter gene. In some instances a reporter gene may be used with or without a selectable marker. Reporter genes are genes which are typically not present in the recipient organism or tissue and typically encode for proteins resulting in some phenotypic change or enzymatic property. Examples of such genes are provided in K. Wising et al. Ann. Rev. Genetics, 22, 421 (1988), which is incorporated herein by reference. Preferred reporter genes include the beta-glucuronidase (GUS) of the uidA locus of E. coli, the chloramphenicol acetyl transferase gene from Tn9 of E. coli, the green fluorescent protein from the bioluminescent jellyfish Aequorea victoria, and the luciferase genes from firefly Photinus pyralis. An assay for detecting reporter gene expression may then be performed at a suitable time after said gene has been introduced into recipient cells. A preferred such assay entails the use of the gene encoding beta-glucuronidase (GUS) of the uidA locus of E. coli as described by Jefferson et al., (Biochem. Soc. Trans. 15, 17-19 (1987)) to identify transformed cells. In preparing the recombinant DNA constructs (vectors) of the present invention, the various components of the construct or fragments thereof will normally be inserted into a convenient cloning vector, e.g., a plasmid that is capable of replication in a bacterial host, e.g., E. coli. Numerous cloning vectors exist that have been described in the literature, many of which are commercially available. After each cloning, the cloning vector with the desired insert may be isolated and subjected to further manipulation, such as restriction digestion, insertion of new fragments or nucleotides, ligation, deletion, mutation, resection, etc. so as to tailor the components of the desired sequence. Once the construct has been completed, it may then be transferred to an appropriate vector for further manipulation in accordance with the manner of transformation of the host cell. A plant recombinant DNA construct (vector) of the present invention may also include a chloroplast transit peptide, in order to target the polypeptide of the present invention to the plastid. The term "plastid" means the class of plant cell organelles that includes amyloplasts, chloroplasts, chromoplasts, elaioplasts, eoplasts, etioplasts, leucoplasts, and proplastids. These organelles are self-replicating, and contain what is commonly referred to as the "chloroplast genome," a circular DNA molecule that ranges in size from about 120 to about 217 kb, depending upon the plant species, and which usually contains an inverted repeat region. Many plastid-localized polypeptides are expressed from nuclear genes as precursors and are targeted to the plastid by a chloroplast transit peptide (CTP), which is removed during the import steps. Examples of such chloroplast polypeptides include the small subunit of ribulose-l,5-biphosphate carboxylase (ssRUBISCO, SSU), 5-enolpyruvateshikimate-3-phosphate synthase (EPSPS), ferredoxin, ferredoxin oxidoreductase, the light-harvesting-complex protein I and protein II, and thioredoxin F. It has been demonstrated that non-plastid polypeptides may be targeted to the chloroplast by use of polypeptide fusions with a CTP and that a CTP sequence is sufficient to target a polypeptide to the plastid. Those skilled in the art will also recognize that various other recombinant DNA constructs can be made that utilize the functionality of a particular plastid transit peptide to import the enzyme into the plant cell plastid depending on the promoter tissue specificity. The present invention also provide a transgenic plant comprising in its genome an isolated nucleic acid which comprises: (A) a 5' non-coding sequence which functions in the cell to cause the production of a mRNA molecule; which is operably linked to (B) a structural nucleotide sequence encoding an ^ 4NE-like polypeptide of this invention; which is operably linked to (C) a 3' non-translated sequence that functions in said cell to cause termination of transcription. Preferably, the amino acid sequence of the ANT-like polypeptide has at least 60%> sequence identity, at least 65% sequence identity, at least 70% sequence identity, or at least 75% sequence identity to a member selected from the group consisting of SΕQ ID ΝOs: 2, 4, 6, 9, 11, and 13. More preferably, the amino acid sequence of the ^ 4NE-like polypeptide has at least 80% sequence identity, at least 85% sequence identity, or at least 90% sequence identity to a member selected from the group consisting of SΕQ ID ΝOs: 2, 4, 6, 9, 11, and 13. Even more preferably, the amino acid sequence of the the NE-like polypeptide has at least 95% or 98% sequence identity to a member selected from the group consisting of SEQ ID NOs: 2, 4, 6, 9, 11, and 13. Most Preferably, the amino acid sequence of the ANT-like polypeptide is selected from the group consisting of SEQ ID NOs: 2, 4, 6, 9, 11, and 13. The above described polypeptide can also have one of the sequences set forth in SEQ ID NOs: 2, 4, 6, 9, 11, and 13 with conservative amino acid substitutions. Transgenic plants of the present invention preferably have incorporated into their genome or transformed into their chloroplast or plastid genomes an exogenous nucleic acid molecule (or "transgene"), that comprises at least a structural nucleotide sequence that encodes an ylNE-like polypeptide having an amino acid sequence selected from the group consisting of SΕQ ID ΝOs: 2, 4, 6, 9, 11, and 13. Transgenic plants are also meant to comprise progeny (descendant, offspring, etc.) of any generation of such a transgenic plant. A seed of any generation of all such transgenic plants wherein said seed comprises a DΝA sequence encoding the ^ 4NE-like polypeptide of the present invention is also an important aspect of the invention. In one embodiment, the transgenic plants of present invention will have increased size of seeds, fruits, roots, tubers, stems, bulbs and leaves due to the overexpression of an exogenous nucleic acid molecule encoding an ^ 4NE-like polypeptide. In a preferred embodiment, the transgenic plants of present invention will have increased size of seeds, fruits, roots, and tubers. In a more preferred embodiment, the transgenic plants of present invention will have increased size of seeds and fruits. In a particularly preferred embodiment, the transgenic plants of present invention will have increased size of seeds and proportionally increased contents of seed proteins, seed oils or seed carbohydrates. The term "increased size", as used herein in reference to an organ (e.g., seed, root, shoot, stem, etc.) of the transgenic plant of the present invention, means that the organ has a significantly greater volume or dry weight or both as compared to the volume or dry weight of same organ of a corresponding wild type plant. It is recognized that there can be natural variation in the size of an organ of a particular plant species. However, the organ of increased size of the trangenic plant of the present invention can be identified by sampling a population of that organs and determining that the normal distribution of the organ sizes is greater, on average, than the normal distribution of the organ sizes of a wild type plant. The volume or dry weight of an organ is, on average, usually at least 5% greater, 10% greater, 30%) greater, 50%. greater, 75% greater, more usually at least 100%) greater, and most usually at least 200%> greater than in the corresponding wild type plant species. The DNA constructs of the present invention may be introduced into the genome of a desired plant host by a variety of conventional transformation techniques, which are well known to those skilled in the art. Preferred methods of transformation of plant cells or tissues are the Agrobacterium mediated transformation method and the biolistics or particle-gun mediated transformation method. Suitable plant transformation vectors for the purpose of Agrobacterium mediated transformation include those derived from a Ti plasmid of Agrobacterium tumefaciens, as well as those disclosed, e.g., by Herrera-Estrella et al., Nature 303:209 (1983); Bevan, Nucleic Acids Res. 12: 8711-8721 (1984); Klee et al., Bio-Technology 3(7): 637-642 (1985); and EPO publication 120,516. In addition to plant transformation vectors derived from the Ti or root- inducing (Ri) plasmids of Agrobacterium, alternative methods can be used to insert the DNA constructs of this invention into plant cells. Such methods may involve, but are not limited to, for example, the use of liposomes, electroporation, chemicals that increase free DNA uptake, free DNA delivery via microprojectile bombardment, and transformation using viruses or pollen. A plasmid expression vector suitable for the introduction of a nucleic acid encoding an ^ 4NE-like polypeptide in monocots using electroporation or particle-gun mediated transformation is composed of the following: a promoter that is constitutive or tissue-specific; an intron that provides a splice site to facilitate expression of the gene, such as the Hsp70 intron (PCT Publication WO93/19189); and a 3' polyadenylation sequence such as the nopaline synthase 3' sequence (ΝOS 3'; Fraley et al., Proc. Νatl. Acad. Sci. USA 80: 4803-4807(1983)). This expression cassette may be assembled on high copy replicons suitable for the production of large quantities of DΝA. An example of a useful Ti plasmid cassette vector for plant transformation is pMOΝ- 17227. This vector is described in PCT Publication WO 92/04449, herein incorporated by reference in its entirety, and contains a gene encoding an enzyme conferring glyphosate resistance (denominated CP4), which is an excellent selection marker gene for many plants. The gene is fused to the Arabidopsis ΕPSPS chloroplast transit peptide (CTP2) and expressed from the FMN promoter as described therein. Certain portions of pMOΝ vectors described herein (i.e. in the figures) have elements described in said PCT publication. All transformation vectors include a left border (LB), right border (RB), orf-7, p-NOS, NOS 3', and a selectable marker, in addition to other element required for propagation in bacteria, insertion into plant genomic DNA, and propagation in callus and mature plants. When adequate numbers of cells (or protoplasts) containing the exogenous nucleic acid molecule encoding an .^NE-like polypeptide are obtained, the cells (or protoplasts) can be cultured to regenerated into whole plants. Such regeneration techniques rely on manipulation of certain phytohormones in a tissue culture growth medium, typically relying on a biocide and/or herbicide marker which has been introduced together with the desired nucleotide sequences. Choice of methodology for the regeneration step is not critical, with suitable protocols being available for hosts from Leguminosae (alfalfa, soybean, clover, etc.), Umbelliferae (carrot, celery, parsnip), Cruciferae (cabbage, radish, canola/rapeseed, etc.), Cucurbitaceae (melons and cucumber), Gramineae (wheat, barley, rice, maize, etc.), Solanaceae (potato, tobacco, tomato, peppers), various floral crops, such as sunflower, and nut-bearing trees, such as almonds, cashews, walnuts, and pecans. See, for example, Ammirato et al., Handbook of Plant Cell Culture - Crop Species. Macmillan Publ. Co. (1984); Shimamoto et al., Nature 338:274-276 (1989); Fromm, UCLA Symposium on Molecular Strategies for Crop Improvement, April 16-22, 1990. Keystone, CO (1990); Nasil et al., Bio/Technology 8:429-434 (1990); Nasil et al., Bio/Technology 10:667-674 (1992); Hayashimoto, Plant Physiol. 93:857-863 (1990); and Datta et al., Bio-technology 8:736-740 (1990). Plant regeneration from cultured protoplasts is described in Evans et al., Protoplasts Isolation and Culture, Handbook of Plant Cell Culture, pp. 124-176, MacMillilan Publishing Company, New York, 1983; and Binding, Regeneration of Plants, Plant Protoplasts, pp. 21-73, CRC Press, Boca Raton, 1985. Regeneration can also be obtained from plant callus, explants, organs, or parts thereof. Such regenration techniques are described generally in Klee et al., Ann. Rev. Plant Phys. 38:467-486 (1987). A transgenic plant formed using Agrobacterium transformation methods typically contains a single exogenous gene on one chromosome. Such transgenic plants can be referred to as being heterozygous for the added exogenous gene. More preferred is a transgenic plant that is homozygous for the added exogenous gene; i.e., a transgenic plant that contains two added exogenous genes, one gene at the same locus on each chromosome of a chromosome pair. A homozygous transgenic plant can be obtained by sexually mating (selfing) an independent segregant transgenic plant that contains a single exogenous gene, germinating some of the seed produced and analyzing the resulting plants produced for the exogenous gene of interest. A explanation of what Agrobacterium is, and how it has come to be used in the art can be seen in Box 21.1, p. 1108, in the text Biochemistry and Molecular Biology of Plants, editors Buchanan, Gruissem, and Jones, American Society of Plant Physiologists, Rockville, MD (ISBN 0-943088- 39-9). The development or regeneration of transgenic plants containing the exogenous nucleic acid molecule that encodes a polypeptide of interest is well known in the art. Preferably, the regenerated plants are self-pollinated to provide homozygous transgenic plants, as discussed above. Otherwise, pollen obtained from the regenerated plants is crossed to seed-grown plants of agronomically important lines. Conversely, pollen from plants of these important lines is used to pollinate regenerated plants. A transgenic plant of the present invention containing a desired ^ 4NE-like polypeptide is cultivated using methods well known to one skilled in the art. Plants that can be made to have increased size of plant organs by practice of the present invention include, but are not limited to, Acacia, alfalfa, aneth, apple, apricot, artichoke, arugula, asparagus, avocado, banana, barley, beans, beet, blackberry, blueberry, broccoli, brussels sprouts, cabbage, canola, cantaloupe, carrot, cassava, cauliflower, celery, cherry, cilantro, citrus, Clementines, coffee, corn, cotton, cucumber, Douglas fir, eggplant, endive, escarole, eucalyptus, fennel, figs, gourd, grape, grapefruit, honey dew, jicama, kiwifruit, lettuce, leeks, lemon, lime, Loblolly pine, mango, melon, mushroom, nut, oat, okra, onion, orange, an ornamental plant, papaya, parsley, pea, peach, peanut, pear, pepper, persimmon, pine, pineapple, plantain, plum, pomegranate, poplar, potato, pumpkin, quince, radiata pine, radicchio, radish, raspberry, rice, rye, sorghum, Southern pine, soybean, spinach, squash, strawberry, sugarbeet, sugarcane, sunflower, sweet potato, sweetgum, tangerine, tea, tobacco, tomato, turf, a vine, watermelon, wheat, yams, and zucchini. Plant organs (e.g., seed) obtained from the transgenic plants of the present invention can be analyzed according to well known procedures to identify organs with desired trait. Increased size can be determined by weighing organs (e.g., seed) or by visual inspection. Protein content is conveniently measured by the method of Bradford et al., Anal. Biochem.. 72: 248 (1976). Oil content can be determined using NIR spectroscopy or standard procedures such as gas chromatography. The present invention also provides parts of the transgenic plants of the present invention. Plant parts, without limitation, include seed, endosperm, ovule and pollen. In a particularly preferred embodiment of the present invention, the plant part is a seed. The present invention also further provides method for generating a transgenic plant having increased size of one or more plant organs, the method comprising the steps of: a) introducing into the genome of the plant an exogenous nucleic acid molecule comprising in the 5' to 3' direction i) a promoter that functions in the cells of said plant, said promoter operably linked to; ii) a structural nucleotide sequence encoding an ^ 4NE-like polypeptide the amino acid sequence of which is substantially identical to a member selected from the group consisting of SΕQ ID Νos: 2, 4, 6, 9, 11, and 13, said structural nucleotide sequence operably linked to; iii) a 3' non-translated nucleotide sequence that functions in said cells of said plant to cause transcriptional termination; b) obtaining transformed plant cells containing the nucleotide sequence of step (a); and c) regenerating from said transformed plant cells a transformed plant in which said ^ 4NE-like polypeptide is overexpressed. Larger seeds, or seeds with different characteristics than normal (i.e. increased or decreased starch, sugar, or oil) of plants can be used to improve the efficiency of many processes in industrial plants. For example, ethanol can be produced from com or other starchy grain. The grain is first ground into meal and then is slurried with water to form a mash. Enzymes are added to the mash to convert the starch to the simple sugar, dextrose. Ammonia is also added for pH control and as a nutrient to the yeast. The mash is processed through a high temperature, cook step to reduce bacteria levels ahead of fermentation. The mash is cooled and transferred to the fermenters where yeast is added and the conversion of sugar to ethanol and carbon dioxide begins. After fermentation, the resulting "beer" is transferred to distillation where the ethanol is separated from the residual "stallage". The ethanol is concentrated to 190 proof using conventional distillation and then is dehydrated to approximately 200 proof in a molecular sieve system. After this anhydrous ethanol is blended with about 5% denaturant and it is ready for shipment to gasoline terminals or retailers. The above process is known as "dry milling", there is also a process called "wet milling". Larger seeds, or seeds with more starch, might be expected to create a greater per seed yield of ethanol that conventional seeds. The United States and the rest of the world use com primarily as livestock feed. 61% of the world com production in 1997 was consumed as animal feed. In the United States, com represents 86% of the grain used as feed. Dent com is the most important commercial type of corn grown in the United States. Predominantly yellow or white, the dent com kernel forms a dent on the crown of the kernel at maturity. Other major commercial types of com include: flint com, sweet com, and popcorn. Specialty corns grown commercially in the United States include waxy com, high-amylose com, high-oil com, and high-lysine com. The com or other seed produced as part of the present invention could be used as feed com, and might be expected to carry more net value per seed than conventional, non-transgenic seed. The following examples are provided to better elucidate the practice of the present invention and should not be interpreted in any was to limit the scope of the present invention. Those skilled in the art will recognize that various modifications, truncations, etc., can be made to the methods and genes described herein while not departing from the spirit and scope of the present invention. In the following examples references to proprietary database and proprietary libraries, e.g., of DNA clones, describe private databases and libraries available to the inventors ■ from Monsanto Biotechnology LLC. Example 1 This example illustrates how cDNA clones encoding soybean ^4NE-like polypeptides were identified and isolated. To identify soybean ANT-like genes in propriety databases, a similarity analysis using the BLAST software (Basic Local Alignment Search Tool, Altschul et al., J. Mol. Biol. 215:403-410 (1990), herein incorporated by reference in its entirety) was performed. The amino acid sequence of the ^4rαbz op ^NE (gl244708) polypeptide was used as a query to search and align soybean DΝA databases that were translated in all six reading frames, using the TBLASTΝ algorithm provided by the ΝCBI. Such similarity analysis of the proprietary databases resulted in the identification of numerous ΕSTs and cDΝA contigs which have Ε value as high as 8.00Ε-92, or a P score as high as 337, with the alignment predominantly limited to the AP2 DNA binding domain. To determine whether the identified clones comprise coding sequences encoding the homologues of the Arabidopsis ANT, all the hits were subjected to contig assembly using the GCG Assembly algorithm provided by Incyte Genomics, Inc. (Palo Alto, CA), which resulted in the formation of 36 contigs for the top 100 hits. Seven clones, LIB3242-515-P1-J1-C1, LIB3242-362-Ql-Jl-Bl, LIB3242-345-Ql-Jl-Fl,LIB3209-010-Ql-Bl-B7, LIB3242-690-P1-J1- E6, LIB3139-020-P1-N1-D12, AND 701124935H1, each containing a putative ATG start codon and each representing one of the top seven contigs with respect to similarity to the Arabidopsis ANT, were chosen for full-length insert sequencing. The subsequent alignment of the obtained full-length sequences with the Arabidopsis ANT polypeptide showed that they share little similarity to the Arabidopsis ANT outside the AP2 DΝA binding domain, suggesting that those sequences are not likely ANT-like polypeptide coding sequences. Considering the fact the AP2 DΝA binding domain-containing genes represent a large family of plant genes with highly conserved AP2 DΝA-binding domain, it would be unlikely that ^ 4NE-like polypeptide coding sequence could be faithfully identified by conventional BLAST search for top hits. This could explain why the top blast hits in the above standard sequence comparison might not be NE-like polypeptide coding sequences. The inventors of the present invention predicted that the functional (transcriptional activating) domains are likely to reside in the flanking sequences and sequence similarity in such regions with the Arabidopsis ANT might be expected for genes performing similar functions. Based on the assumption, all hits with a Ε value below 1Ε-7 were analyzed to look for sequence similarity to the Ν-terminal of the Arabidopsis ANT polypeptide before the two AP2 DΝA binding domains. Three sequences (ESTs) were identified, which rank 45 th , 61 st , and 66 th , respectively, in the BLAST list, all of three sequences showing modest similarity (E value ranging from 2.00E-15 to 4.00E-10) to the sequence of the Ν-terminal before the two AP2 DΝA binding domains of the Arabidopsis ANT polypeptide. Two of these three sequences were subsequently linked together using sequence contig analysis. A second round of BLAST was performed using the identified ESTs as queries, which resulted in the identification of two potentially full-length cDΝAs (containing a putative ATG translation start), namely LIB3242- 100-Q1-J1-E2 (plasmid CPR67663) and LIB3242-078-P1-J1-F10 (plasmid CPR67626). When cDNA libraries are primed with poly-dT as a primer, the primer sits on the 3' end of the mRNA. Reverse transcriptase uses this poly-dT as a primer and extends a DNA polynucleotide (often called a cDNA or copy DNA) using the mRNA as a template. Often, the reverse transcriptase does not extend the new DNA polynucleotide the entire length of the mRNA, resulting in truncated transcripts. One way to find putative full length clones is to look for the putative ATG (AUG), the probable translation start site. The entire inserts of CPR67663 and CPR67626 were sequenced, and the full-length sequences of these two cDNAs were named as GmANTl (SEQ ID NO: 1) and GmANT2 (SEQ ID NO: 3), respectively. GmANTl and GmANT2 were translated into amino acid sequences (SEQ ID NO: 2 and SEQ ID NO: 4) using the standard genetic code, as shown in the Sequence Listing. Pfam protein domain search showed that both GmANTl and GmANT2 polypeptides each contain two typical AP2 DNA-binding domains. Three major observations were made when translated GmANTl, GmANT2 and the conventional top BLAST hits described above were aligned with Arabidopsis ANT. First, the two AP2 DNA binding domains of GmANTl and GmANT2 polypeptides share even better homologies with the Arabidopsis ANT polypeptide than the top hits with Arabidopsis ANT polypeptide, suggesting that GmANTl and GmANT2 may have ^ 4NE-like activity. Second, by sequence comparison of ANT, GmANTl and GmANT2 polypeptides, four highly conserved segments were identified in the N-terminal before the AP2 DNA binding domains (Figure 1), suggesting that these regions may play some functional roles. In addition, they may be used as a signature in identifying other ANT homologs from other plants. Third, the C-terminal sequences of GmANTl and GmANT2 polypeptides after the AP2 DNA binding domains bear little, if any, homology to that of ANT but they share conserved segments (Figure 1) with each other, suggesting that those portions of the sequences may not only perform additional or distinguishable function from the Arabidopsis ANT polypeptide, but may also be used to identify similar genes that would otherwise be missed if the C-terminal after AP2 DNA binding domains of the Arabidopsis ANT polypeptide was used as query sequence. This C-terminal region distinguishes the novel sequences claimed in the present invention from Arabidopsis ANT polypeptide and can be used by someone skilled in the art to further identify sequences related to this present invention. For an example of how the cDNA libraries used in this example were constructed, see Example 6. Example 2 This example illustrates how rice ^NE-like genes were identified and how a cDΝA clone encoding a rice ^ 4NE-like polypeptide was isolated. The Ν-terminal of 297 amino acid residues of the GmANTl polypeptide (N- terminal 297 amino acids of SΕQ ID NO: 2), which corresponds to the region of amino acid sequence prior to the AP2 DNA binding domains (sometimes referred to herein as "GmANT with AP2 binding domains deleted"), was used as the query sequence to carry out similarity analysis of proprietary rice databases, using similar procedures as described in Example 1. Six rice BAC contigs were identified to contain potential open reading frames with E values ranging from 5e- 17 to 9e-07. These six contigs were derived from two chromosomal loci. By comparing open reading frames that encode ANT-like polypeptides, it has been found that the identified six contigs could be represented by two contigs OJ000103_04.0303.C9 and OJ000315_30.0419.C7, respectively, since five of the six contigs all contain an open reading frame that encodes the same .^NT-like polypeptide. When using the C-terminal of 200 amino acid residues of GmANTl after the AP2 DNA binding domains as the query sequence in the similarity analysis of proprietary rice databases, the same six contigs were also identified. However, when the C-terminal of 200 amino acid residues of the Arabidopsis ANT polypeptide after the AP2 DNA binding domains was used as the query sequence, the six rice BAC contigs were not identified. A combination of GenScan (Burge and Karlin, J. Mol. Biol. 268: 78-94 (1997), herein incorporated by reference in its entirety) and GenMark (Lukashin and Borodovsky, Nucleic Acid Res. 26: 1107-1115 (1998), herein incorporated by reference in its entirety) algorithms predicted an open reading frame (ORF) from each of the two rice BAC contigs. The software GeneMark.hmm (version 2.2) was used to predict genes/exons. The predicted exons from OJ000103_04.0303.C9 encodes a polypeptide of 540 amino acid residues and the coding sequence was designated as OsANTl, and the predicted exons from OJ000315_30.0419.C7 (SEQ ID NO: 7) encodes a polypeptide of 669 amino acid residues and the coding sequence is designated as OsANT2 (SEQ ID NO: 8). RT-PCR was performed to isolate the full-length cDNA that might have been transcribed from the above predicted gene OsANTl. Two primers, GAGCGTGTGCATGGTTGGTG (pOsANTl- 10) (SEQ ID NO: 23) and CTCGAGGCATCTGTCCAGGCTGCAAAAAC (pOsANTl-2) (SEQ ID NO: 24) were designed for RT-PCR cloning, where pOsANTI-10 anneals at -8 upstream to the start of the predicted open reading frame and pOsANTl-2 anneals at the stop of the predicted open reading frame. Total rice RNAs were isolated from roots, leaves and panicles, and were subjected to first-strand cDNA synthesis using Superscript II reverse transcriptase (BRL/Life Technologies Inc., Gaithersburg, MD), using conditions recommended by the manufacturer. The synthesized rice cDNAs were then used as the template for PCR amplification using the gene-specific primers pOsANTI-10 and pOsANTl-2 and the Platinum High Fidelity Taq DNA Polymerase (BRL/Life Technologies Inc., Gaithersburg, MD). PCR cycling conditions were as follows: 94°C, 40 seconds, followed 30 cycles of 94°C, 25 seconds; 55°C, 30 seconds and 68°C, 2 minutes 30 seconds. The amplification product was verified and purified by agarose gel eletrophoresis. The rice ANT cDΝA, named as OsANTl, was amplified from the rice panicle RΝAs, but not from that of roots and leaves, suggesting tissue-differential expression of the gene. The purified OsANTl cDΝA was then cloned into TA vector (Invitrogen Corporation, San Diego, CA), and a PCR-error-free clone was identified by sequencing (sequencing techniques for this and other examples are described in example 23). The coding region (SΕQ ID ΝO:5) of OsANTl is 1926 bp, which encodes a polypeptide (SΕQ ID NO: 6) of 641 amino acid residues. Sequence comparison showed multiple deviations in gene structure of the authentic OsANTl from the predicted one. Polypeptide sequence analysis show that the OsANTl polypeptide shares high homology with ANT, GmANTl and GmANT2 polypeptides at the AP2 DNA binding domains, shares conserved segments at the N-terminal, and shares conserved segments with GmANTl and GmANT2 polypeptides, but not ^ 4NE polypeptide, at the C-terminal. For an example of how the cDΝA libraries used in this example were constructed, see Example 6. Example 3 This example illustrates how cDΝA clones encoding cotton ANT-like polypeptides were identified and isolated. To identify cotton cDNA clones encoding ANT-like polypeptides, the N-terminal 297 amino acid sequence of GmANTl was used as the query sequence to search proprietary cotton DNA databases employing a similarity analysis using the BLAST software (Basic Local Alignment Search Tool, Altschul et al., J. Mol. Biol. 215:403-410 (1990), herein incorporated by reference in its entirety) (similar techniques were employed as in Example 1). These databases included EST sequences from cotton. Three proprietary cDNA clones, LIB3582-058-P1-K1-E4, LIB3829-001-Q1-K6-E4 and LIB3582-030-P1-K1-D12, were identified as the only hits that showed appropriate homology, with scores of E= 4e-12, 3e-l l and le-05, respectively. The first two clones were partial, while the third one, LIB3582-030-Pl-Kl-D12,appeared to be a full length clone. This determination was made by looking for the start codon, AUG, the putative start codon was only present in clone LIB3582-030-P1-K1-D12.. Full length sequence was determined as in example 1. Sequencing confirmed that SEQ ID NO: 10 is a full-length cDNA that shares homology to the Arabidopsis ANT polypeptide (Figures 1 and 2) both in and outside the AP2 DNA binding domains. This gene was named GhANTl (Figure 2; SEQ ID NO: 10). GhANTl (SEQ ID NO: 10) is 1758 bp in length, encoding a polypeptide (SEQ ID NO: 11) of 585 amino acid residues. For an example of how the cDNA libraries used in this example were constructed, see Example 6. Example 4 This example illustrates how nucleotide sequences encoding maize ANT-like polypeptides were identified. It was believed by the inventors that using ^ 4NE-like genes from monocots instead of their dicot counterparts to search for AΝT like sequences in other monocots might lead to better matches as evolutionary divergence would be expected to be less significant. The rice OsANTl with its AP2 DΝA-binding domain deleted (SΕQ ID No. 6; OsANTl -AP2 is equivalent to amino acids 1-288 and 457-642 joined together) was used instead of the Gm ANTI used in example 3. . The search was done employing a similarity analysis using the BLAST software (Basic Local Alignment Search Tool, Altschul et al., J. Mol. Biol. 215:403-410 (1990), herein incorporated by reference in its entirety) of proprietary databases (search was similar to that done in example 1). Such a search identified, in addition to a number of partial genomic DNA sequences, a cDNA clone, LIB3245-486-P1-K1-D7, with an E value of le-05. The full length insert of this cDNA clone (plasmid CPR82516) was sequenced and designated as ZmANTl (SEQ ID NO: 12). Sequence analysis indicates that it is a partial coding sequence that encodes the C-terminal of 255 amino acid residues of a corn v4NE-like polypeptide (SΕQ ID NO: 13), sharing close to 60%> sequence identity to the OsANTl polypeptide (see Table I) For an example of how the cDNA libraries used in this example were constructed, see Example 6. Example 5 Sequence comparison of ANT and yliVT-like polypeptides The data in Table 1 represents a calculation of the percentage sequence identity of the amino acid sequences set forth in SEQ ID Nos: 2, 4, 6, 9, 11, and 13 and Arabidopsis ANT polypeptide (gil244708). Sequence alignments and calculations of percentage sequence identity were performed using Gap in the WISCONSIN PACKAGE version 10.0-UNIX from Genetics Computer Group, Inc. based on the method of Needleman and Wunsch (J. Mol. Biol. 48:443-453 (1970)) using the set of default parameters for pairwise comparison (Gap Creation Penalty = 8; Gap Extension Penalty = 2). Table 1 shows that the amino acid sequences of the NE-like polypeptides of the present invention have less than 60% sequence identity to that of the Arabidopsis ANT polypeptide. The data in Table 2 represents a calculation of the percentage sequence identity of the nucleotide sequences set forth in SΕQ ID Νos: 1, 3, 5, 1, 8, 10, and 12 and Arabidopsis ANT (gi 1244707). Sequence alignments and percent identity calculations were performed using Gap in the WISCONSIN PACKAGE version 10.0-UNIX from Genetics Computer Group, Inc. based on the method of Needleman and Wunsch (J. Mol. Biol. 48:443-453 (1970)) using the set of default parameters for pairwise comparison (Gap Creation Penalty = 50; Gap Extension Penalty = 3). Table 2 shows that the nucleotide sequences encoding the NE-like polypeptides of the present invention have less than 60% sequence identity to the nucleotide sequence encoding the Arabidopsis ANT polypeptide. The deduced amino acid sequence of the Arabidopsis ANT polypeptide (g 1244708, Klucher et al, Plant Cell 8:137-153 (1996)) is compared with those of the ^NE-like polypeptides of the present invention, including GmA Tl and GmANT2 polypeptides from soybean, OsANTl and OsANT2 polypeptides from rice, GhANTl polypeptide from cotton, and ZmANTl polypeptide (partial sequence) from com (Figure 2). The multiple alignment was performed using the software CLUSTALW version 1.74 from the public domain (Thompson et al, Nucleic Acids Res. 22:4673-4680 (1994), herein incorporated by reference in its entirety) using default parameters. Figure 2 shows that all the ^ 4NE-like polypeptides of the present invention and the Arabidopsis ANT polypeptide contain two highly conserved DΝA-binding motifs (domains), one located at 281-354, the other at 383-448, with reference to the Arabidopsis ANT polypeptide. The extra 14 amino acid residues of the OsAΝT2 polypeptide within the second AP2 DNA binding domain is likely a result of inaccurate gene prediction from rice genomic sequences in that region. The comparison also identifies several conserved regions outside the AP2 DNA binding domains, both at the N- and the C-termini. There are at least three regions (shaded) in the N- terminus that are highly conserved across all the 4NE-like polypeptides. There are also three conserved regions (shaded) in the C-terminus, with the Arabidopsis ANT polypeptide showing the least homology, especially for the first two regions. All these conserved sequences outside the AP2 DΝA binding domain are unique to the ^ 4NE-like genes, suggesting that they may be important for ._4NE-like function, and may be used as the signature sequences in the identification of coding sequences encoding other ^ 4NE-like polypeptides. The relative relatedness (phylogenic tree) of GhANTl, ANT, GmANTl, GmANT2, OsANTl and ZmANTl is shown in Figure 3 (for SΕQ ID's, see figure). The multiple alignment was first performed according to the procedure described for Figure 2 and then the phylogenic tree was constructed using the software PHYLIP (Phylogeny Inference Package) version 3.5c provided as : "Felsenstein, J. 1993. PHYLIP version 3.5c. Distributed by the author. Department of Genetics, University of Washington, Seattle." Subroutines and parameters used were: "seqboot" (parameter: -D 'Molecular sequences' -R 100 -J 'Bootstrap' ), "protdist" (parameter: - P 'PAM', -M 'Yes 100'), "kitsch" (parameter: -U 'Yes', -P 2.00000, -L 'No' -R 'No' -S 'No' -J 'No' -M 'Yes, 100' - 'No' ) , and "consense" (parameter: -R 'Yes'). Genome-wide search suggests that Arabidopsis has only one ANT gene (gl244708), while unexpectedly rice apparently has two NE-like genes (OsANTl and OsAΝT2). Figure 3 show that the ^ 4NE-like genes appear diverged between monocots and dicots and that the cotton GhANTl may not bethe closest ^NE-like gene from that species. Example 6 This example illustrates how cDNA libraries (Table 4), which contain cDNA clones identified in Example 1 through Example 4, were constructed. Table 4. cDNA libraries from soybean, cotton, and corn The cDNA library (LIB3209) is generated from soybean cultivar Asgrow 3244 (Asgrow Seed Company, Des Moines, Iowa U.S.A.) partially to fully opened flower tissue. Partially to fully opened flower tissue is harvested from plants grown in an environmental chamber under 12hr daytime/12hr nighttime cycles. The daytime temperature is approximately 29°C and the nighttime temperature approximately 24°C. Soil is checked and watered daily to maintain even moisture conditions. A total of 3 grams of flower tissue is harvested and immediately frozen in dry ice. The harvested tissue is then stored at -80°C until RNA preparation. The RNA is purified from the stored tissue and the cDNA library is constructed as described in Example 21. The normalized cDNA library (LIB3139) is prepared from soybean cultivar Asgrow 3244 roots harvested from plants grown in a field. Plants are uprooted and roots are quickly rinsed in a pail of water. Roots are then cut from the plants, placed immediately in 14ml polystyrene tubes and immersed in dry-ice. The collected root samples are then transferred to a -80°C freezer for storage. A first root sample is collected from 76 plants at the V4 stage; a second root sample {ca. 28g), from 15 days after flowering (DAF) plants; a third root sample {ca. 61g), from 25 DAF plants; a fourth root sample {ca. 38g), from 35 DAF plants; a fifth root sample {ca. 28g), from 45 DAF plants; a sixth root sample {ca. 22g), from 55 DAF plants; a seventh root sample {ca. 27g), from 65 DAF plants; and a eighth root sample {ca. 40g), from 75 DAF plants. Total RNA (Soy6) is prepared from the first root sample; total RNA (Soy25), from the second root sample; total RNA (Soy29), from the combination of equal amounts of the third and fourth root sample; total RNA (Soy31), from the combination of equal amounts of the fifth and sixth root sample; and total RNA (Soy39), from the combination of equal amounts of the seventh and eighth root sample. The RNA is purified from the stored tissue and four cDNA library are constructed as described in Example 21. Equal amounts of DNA materials from the four cDNA libraries, in the form of double stranded DNA, are mixed and used as the starting material for normalization. Biotinylated genomic soybean DNA is used as the driver for the normalization reaction. Double stranded plasmid DNA representing approximately 1X10 6 colony forming units is used as the target. The double stranded plasmid DNA is isolated using standard protocols. Approximately 4 micrograms of biotinylated genomic DNA is mixed with approximately 6 micrograms of double stranded plasmid DNA and allowed to hybridize. Genomic DNA-plasmid DNA hybrids are captured on Dynabeads M280 Streptavidin (Dynal Biotech, Oslo, Norway). The dynabeads with captured hybrids are collected with a magnet. Captured hybrids are eluted in water. The resulting clones are subjected to a second round of hybridization identical to the first. The SOYMON019 cDNA library is generated from soybean cultivars Cristalina (USDA Soybean Germplasm Collection, Urbana, Illinois U.S.A.) and FT 108 (Monsoy, Brazil) (tropical germ plasma) root tissue. Roots are harvested from plants grown in an environmental chamber under 12hr daytime/12hr nighttime cycles. The daytime temperature is approximately 29°C and the nighttime temperature approximately 24°C. Soil is checked and watered daily to maintain even moisture conditions. Approximately 50g and 56g of roots are harvested from each of the Cristalina and FT 108 cultivars and immediately frozen in dry ice. The harvested tissue is then stored at -80°C until RNA preparation. The RNA is purified from the stored tissue and the cDNA library is constructed as described in Example 21. The SOYMON032 cDNA library is prepared from the Asgrow cultivar A4922 (Asgrow Seed Company, Des Moines, Iowa U.S.A.) rehydrated dry soybean seed meristem tissue. Surface sterilized seeds are germinated in liquid media for 24 hours. The seed axis is then excised from the barely germinating seed, placed on tissue culture media and incubated overnight at 20°C in the dark. The supportive tissue is removed from the explant prior to harvest. Approximately 570mg of tissue is harvested and frozen in liquid nitrogen. The harvested tissue is then stored at -80°C until RNA preparation. The RNA is purified from the stored tissue and the cDNA library is constructed as described in Example 21. The SOYMON038 cDNA library is generated from soybean variety Asgrow A3237 (Asgrow Seed Company, Des Moines, Iowa U.S.A.) rehydrated dry seeds. Explants are prepared for transformation after germination of surface-sterilized seeds on solid tissue media. After 6days, at 28°C and 18 hours of light per day, the germinated seeds are cold shocked at 4°C for 24 hours. Meristemic tissue and part of the hypocotyl is remove and cotyledon excised. The prepared explant is then wounded for Agrobacterium infection. The 2 grams of harvested tissue is frozen in liquid nitrogen and stored at -80°C until RNA preparation. The RNA is purified from the stored tissue and the cDNA library is constructed as described in Example 21. The SOYMON037 cDNA library is generated from soybean cultivar A3244 (Asgrow Seed Company, Des Moines, Iowa U.S.A.) etiolated axis and radical tissue. Seeds are planted in moist vermiculite, wrapped and kept at room temperature in complete darkness until harvest. Etiolated axis and hypocotyl tissue is harvested at 2, 3 and 4 days post-planting. A total of 1 gram of each tissue type is harvested at 2, 3 and 4 days after planting and immediately frozen in liquid nitrogen. The harvested tissue is then stored at -80°C until RNA preparation. The RNA is purified from the stored tissue and the cDNA library is constructed as described in Example 21. The LIB3582 cDNA library is generated from 24 dpa (days post anthesis) seed axis harvested from cotton plants. The Gossypium hirsutum variety Coker 312 is used for collection. Seeds are planted in trays containing potting soil premixed with fertilizers. Plants are grown in a greenhouse in 16hr day / 8 hr night cycles with an average relative humidity of ca. 50%. Daytime and night time temperature are 90°F and 74°F respectively. Daytime light levels are measured at 600-1000 mEinsteins/m 2 . Plants are watered daily in the morning and as needed in the afternoon. Plants receive 1 or 2 applications of Pix to control excessive growth. Bolls are removed from the plants 24 dpa and opened and tissues are divided to harvest seeds. The harvested seeds are dissected to remove axis from other tissues. The harvested axis tissue is immediately frozen in liquid nitrogen and stored at -80°C until total RNA preparation. The RNA is prepared from the stored tissue and the cDNA library is constructed as described in Example 22. The LIB3829 cDNA library is prepared from gynoecium tissue from 1/3 grown squares (ca. 0.4 cm floral bud) harvested from cotton plants. The Gossypium hirsutum variety Nucotton33B is used for collection. Seeds are planted in trays containing potting soil premixed with fertilizers. Plants are grown in a greenhouse in 16hr day / 8 hr night cycles with an average relative humidity of ca. 50%. Daytime and night time temperature are 90°F and 74°F respectively. Daytime light levels are measured at 600-1000 mEinsteins/m 2 . Plants are watered daily in the morning and as needed in the afternoon. Plants receive 1 or 2 applications of Pix to control excessive growth. 1/3 grown squares (ca. 0.4 cm floral bud) are harvested from cotton plants. The harvested squares are dissected to remove gynoecium from other tissues. The harvested gynoecium tissue is immediately frozen in liquid nitrogen and stored at -80°C until total RNA preparation. The RNA is prepared from the stored tissue and the cDNA library is constructed as described in Example 22. The SATMON012 cDNA library is generated from 2 day post germination maize (DK604, Dekalb Genetics, Dekalb, Illinois U.S.A.) seedlings. Seeds are planted on a moist filter paper on a covered tray that is kept in the dark until germination (one day). Then the trays containing the seeds are moved to the greenhouse and grown at 15hr daytime/9 hr nighttime cycles until 2 days post germination. The daytime temperature is approximately 80°F and the nighttime temperature is approximately 70°F. Tissue is collected when the seedlings are 2 days old. At the two day stage, the coleorhiza is pushed through the seed coat and the primary root (the radicle) is pierced the coleorhiza but is barely visible. Also, at this two day stage, the coleoptile is just emerging from the seed coat. The 2 days post germination seedlings are then immersed in liquid nitrogen and crashed. The harvested tissue is stored at -80°C until preparation of total RNA. The RNA is purified from the stored tissue and the cDNA library is constructed as described in Example 21. Example 7 Construction of pMON57913 pMON57913 is a binary vector for Agrobacterium-mediated transformation and constitutive expression of ANT in Arabidopsis. To clone the Arabidopsis ANT, two gene specific primers, ANT-1 and ANT-2, were designed based on the ANT sequence information {U41339) from the National Center for Biotechnology Information, which is part of the National Library of Medicine, in turn part of the National Institutes of Health (NCBI). The sequence for ANT-1 is CGCGGCGAATTCATGAAGTCTTTTTGTGATAATG (SEQ ID NO: 14), which anneals at the translational start site of ANT and introduces an EcoRI site at the 5' end, while the sequence of ANT-2 is CGCGGCGTCGACGAATCAGCCCAAGCAGC (SEQ ID NO: 15), which anneals at the last codon of ANT and introduces a Sail site at the end of the primer. RT-PCR was performed to isolate Arabidopsis ANT. Specifically, cDNAs were prepared from young Arabidopsis seedling RNAs with Superscript II reverse transcriptase using procedures recommended by the manufacturer (BRL/Life Technologies, Inc., Gainthersburg, MD). PCR was then performed to amplify the NEcDNA using the above prepared cDNA as the template, and ANT-1 and ANT-2 as the primers. The thermal cycling conditions were as follows: 94°C, 40 second, followed by 30 cycles of 94°C, 25 seconds; 55°C, 30 seconds and 68°C, 2 minutes 30 seconds. The amplified ANT cDNA was purified by gel-electrophoresis, and ligated to TA cloning vector using procedures recommended by the manufacturer (Invitrogen Corporation, San Diego, CA). The ligation mix was transformed into E. coli cells for plasmid propagation (Sambrook et al., Molecular Cloning: A Laboratory Manual, 2 nd Edition, Cold Spring Harbor Press, 1989). The transformed cells were plated on appropiate selective media (Sambrook et al., Molecular Cloning: A Laboratory Manual, 2 nd Edition, Cold Spring Harbor Press, 1989) and colonies were scored hours or days later. Plasmids were prepared from individual colonies and full-insert sequence was determined. A number of sequencing techniques are known in the art, including fluorescence-based sequencing methodologies. These methods have the detection, automation and instrumentation capability necessary for the analysis of large volumes of sequence data. Currently, the 377 DNA Sequencer (Perkin-Εlmer Corp., Applied Biosystems Div., Foster City, CA) allows the most rapid electrophoresis and data collection. With these types of automated systems, fluorescent dye-labeled sequence reaction products are detected and data entered directly into the computer, producing a chromatogram that is subsequently viewed, stored, and analyzed using the corresponding software programs. These methods are known to those of skill in the art and have been described and reviewed (Birren et al, Genome Analysis: Analyzing DNA,1, Cold Spring Harbor, New York (1999), the entirety of which is herein incorporated by reference). To clone ANT into an expression vector, the ANT coding sequence from a clone was released from the TA vector by digesting with EcoRI and Sail. This linear DNA segment was then religated to the binary vector pMON23435, that had been linearized by EcoRI and Xhol, using T4 DNA ligase (BRL/Life Technologies, Inc., Gainthersburg, MD). The ligation reaction was performed according to the manufacturer's instruction. The resulting plasmid was confirmed by restriction mapping (for example, see Griffiths, et al, An Introduction to Genetic Analysis, 6 th Edition pρ449-451, ISBN 0-7167-2604-1, W.H. Freeman and Co., New York) and sequencing. As the chosen EcoRI-XhoI cloning site in the vector was flanked by a CaMN e35S promoter at the upstream (5') and an epitope tag (Flag, which encodes the oligo peptide DYKDDDK, SIGMA, St Louis) at the downstream (3 '), the Arabidopsis ANT in this construct is thus tagged at the C-terminus by the Flag epitope tag and will be driven transcriptionally by the CaMV e35S promoter upon transformation in Arabidopsis. Example 8 Construction of pMOΝ57914 pMON57914 was constructed in the same way as for pMON57913 (see Example 7) except that the vector pMON23435 was digested with EcoRI and Sail. It thus contains the ANT gene without the Flag, under the control of the e35S promoter for Arabidopsis transformation and constitutive expression. Example 9 Construction of pMON57955 pMON57955 is a binary vector with GmANTl (SEQ ID NO 2) plus the Flag under the control of the e35S promoter. A pair of PCR primers, GmANTl-1 (SEQ ID NO: 16) and GmANTl-2 (SEQ ID NO: 17), were designed which anneal at the translational start and stop, respectively, with pGmANTl-2 introducing an Xhol site at the end of the coding sequence in order for an in-frame fusion with the Flag, as described in Example 7. These two primers were used to amplify the GmANTl using the plasmid CPR67663 (see Example 1) as the template. The PCR reaction conditions were as described in Example 7. PCR-amplified GmANTl was cloned into the TA vector, and from which an error-free clone was identified, using procedures essentially the same as described in Example 7. To clone the GmANTl gene into a binary vector for plant transformation and expression, the GmANTl -containing TA plasmid was digested with EcoRI and Xhol, and the insert was purified by gel-electrophoresis, which was then ligated to pMON23450 linearized by the same enzymes. Example 10 Construction of pMON57925 pMON57925 is a binary vector with GmANT2 gene plus the Flag at the C-terminus under the control of the CaMN e35S promoter. A pair of PCR primers, GmAΝT2-l (Seq ID NO: 18) and GmANT2-2 (SEQ ID NO: 19), were designed which anneal at the translational start and stop, respectively, with pGmANT2-2 introducing an Xhol site at the end of the coding sequence. After digestion with the restriction enzyme Xhol, and religation to the appropriate plasmid an in- frame fusion with the Flag can be created, as described in Example 7. These two primers were used to amplify the GmANT2 using the plasmid CPR67626 (see Example 1) as the template. The PCR reaction conditions, the TA cloning procedure and error-free clone screening were essentially the same as described in Example 9. Once an error-free clone was obtained, GmANT2 was released from the TA vector by digesting with EcoRV and Xhol, followed by purification from the gel. To prepare the binary vector for the cloning of GmANT2, pMON34450 was first digested with Bglll, followed by Klenow treatment to blunt the ends and, after inactivation of the enzyme, further digesting the plasmid with Xhol. The resulting vector was ligated to the GmANT2 fragment, which was then propagated in E. coli., and a correct clone was identified by restriction mapping and sequencing. Example 11 Construction of pMON57926 pMON57926 is a binary vector with GmANTl (Figure 1 ; SEQ ID NO: 2) plus the Flag under the control of the Arabidopsis Napin promoter for seed specific expression (US patent 6,281,410, for example, see Example 2). To prepare the GmANTl fragment, the same GmANTl -containing TA vector as described in Example 9 was digested by EcoRV and Xhol. To prepare the expression vector for cloning, pMON57233, which has the Napin promoter and the Flag flanking the cloning site, was first digested with Bglll, followed by Klenow treatment to blunt the ends; after inactivation of the Klenow enzyme, the linearized vector was further digested by Xhol, which was then purified and ligated to the prepared GmANTl gene fragment as in Example 9. Example 12 Construction of pMON57927 pMON57927 is a binary vector in which GmANT2 gene with the Flag at the C-terminus is under the control of the Napin promoter for seed-specific expression. Essentially the same procedure was used in the construction as that in Example 11, except that the GmANT2- containing TA plasmid from Example 10 was used as the GmANT2 source. Example 13 Construction of pMON57928 pMON57928 is a binary vector with the Arabidopsis ANT gene plus the Flag under the control of the Napin promoter for seed-specific expression. To prepare the insert, the ANT cassette as described in Example 7 was released from pMON57913 by first digesting with EcoRI, followed by Klenow treatment to blunt the restriction ends. EcoRI creates DNA ends with 5' single stranded DNA overhangs. An enzyme with a DNA polymerization activity (such as the Klenow fragment of DNA polymerase I from E. Coli) can be used to add nucleotides to in order to fill in said overhang, creating a "blunt" end (Sambrook et al., Molecular Cloning: A Laboratory Manual, 2 nd Edition, Cold Spring Harbor Press, 1989). The linearized pMON57913 was further digested with Sail, and the released ANT plus Flag was purified by gel- electrophoresis. The binary expression vector containing the Napin promoter was prepared essentially the same way as that for Example 11. The prepared vector and insert were ligated by T4 DNA ligase, and the construction was confirmed by restriction mapping. Example 14 Construction of pMON57930 pMON57930 is a binary vector in which ANT gene plus the Flag is under the control of the RUBISCO small subunit promoter, SSUIA, for shoot-specific expression (US Patent 5,498,830). The ANT cassette was prepared essentially the same way as that of Example 13. The binary expression vector was pMON57231, which contains the promoter SSUIA, followed by cloning sites including Ncol and Sail. PMON57231 was first digested with Ncol, followed by Klenow treatment to generate a blunt end. After inactivation of the Klenow polymerase, the linearized pMON57231 was further digested with Sail, and the resulting vector was purified by gel-electrophoresis. The purified vector was then ligated to the prepared ANT cassette using standard procedures and manufacturer supplied directions as described in Example 7. Example 15 Construction of pMON57931 pMON57931 is a binary vector with ^ 4NE gene alone (without the epitope Flag, see example 14 for example with Flag) driven by the pSSUlA promoter for shoot-specific expression in plants. To prepare the ANT coding sequence, pMOΝ57914 as described in Example 8 was first digested by EcoRI, followed by treatment with Klenow to generate a blunt- end; after Klenow inactivation, the linearized plasmid was further digested with Sail. The resulting ANT fragment was purified by gel-electrophoresis, and ligated to pMON57231 that was linearized and prepared the same way as that in Example 14. Example 16 Construction of pMON57932 pMON57932 is a binary vector with ANT gene plus the Flag driven by a root-specific promoter, the tobacco RB7 promoter. The ANT cassette was prepared essentially the same as described in Example 13. The binary vector was prepared as follows: pMON57253, which carries the RB7 promoter, was first digested with Bglll, followed by Klenow treatment to blunt the end; the linearized plasmid was further digested by Sail, followed by gel purification. The prepared ANT gene and the pMON57253 were ligated and clones selected and verified using standard procedures as described in above examples. Example 17 Construction of pMON57933 pMON57933 is a binary vector with ^4NE gene alone driven by the RB7 promoter for root-specific expression. Identical procedures were used for the construction as that for Example 16, except that the ANT fragment was prepared as described in Example 15. Example 18 Construction of pMOΝ47934 pMON57934 is a binary vector in which the rice OsANTl polypeptide coding sequence was tagged at the 3' end with the Flag epitope sequence and is driven by the e35S promoter for constitutive plant expression. The OsANTl full-length cDNA was first cloned to a TA vector by RT-PCR, as described in Example 3. The resulting plasmid was then cut with EcoRI to release the OsANTl coding sequence, followed by the purification of the OsANTl gene by gel- electrophoresis. The binary vector pMON23450 was cut with EcoRI and then dephosphorylated by CIAP treatment (New England Biolabs, MA), followed by ligation to the prepared OsANTl gene and propagation in E. coli using standard procedures as described above. The petunia HSP 70 leader used in this construct is described in US patent 5,659,122. Example 19 Construction of pMON57988 PMON57988 is a binary vector for the constitutive expression of the Arabidopsis ANT gene in com. The promoter is the rice actin promoter, P-ractl, from pMON25455. The construction of pMON57988 took two steps: the first step involved the synthesis of the ANT expression cassette in an intermediate vector, the second the construction of the binary expression vector. To construct the expression cassette, pMON57914, which contains the ^4NE gene and was described in Example 8, was first digested with Smal and EcoRI, followed by Klenow treatment to blunt the sticky end generated by EcoRI. The resulting 2330 bp fragment, which included the entire ANT coding sequence and the E9 3 ' terminator, was gel purified. To construct the ^ 4NE expression cassette in an intermediate vector, pMOΝ25455, which contains the R-actl promoter, was digested with Smal and Ncol, followed by Klenow treatment to blunt the end generated by Ncol. The resulting vector fragment, now having the GUS gene removed, was gel purified and ligated to the y4NE-containing fragment prepared above, followed by propagation in Ε. coli. As the ANT insertion could take place in both orientations, plasmids with the correct orientation where P-ractl was in front of ANT was determined by restriction mapping. The identified plasmid was named pMOΝ57989. To put the ANT expression cassette in a binary vector, the cassette was released from pMON57989 by digesting with Notl, followed by gel purification; the binary portion of pMON36176 was also generated by digesting the plasmid with Notl, followed by dephosphorylation with CIAP and gel purification. The prepared ANT cassette and the pMON36176 vector were then ligated and propagated in Ε. coli. Plasmids were prepared from individual colonies for restriction analysis, and a clone with head to head (P-ractl/ANT vs. P-35S/Kan) configuration was selected as pMON57988. This plasmid contains lox sites which can be used to excise the selectable marker using the cre/lox system. Example 20 Construction of pMON57991 pMON57991 was a binary vector in which the Arabidopsis ANT gene was driven by the wheat POX1 (also termed poxl) promoter for root-enhanced expression in plants. Similarly as in Example 19, the construction took two steps: the first step involved the synthesis of the ANT expression cassette with the POX1 promoter in an intermediate vector, the second the mobilization of the cassette into a binary vector. To construct the expression cassette, a 2330 bp fragment including the entire ANT coding sequence and the E9 3' terminator was prepared from pMON57914, as described in Example 19. The promoter POX1 was obtained by digesting pMON36304 with Smal and Ndel, followed sequentially by Klenow filled-in, CIAP (Calf intestinal alkaline phosphotase) dephosphorylation and gel purification. Ligation of the above prepared fragments generated plasmid pMON57996, upon discrimination from those with a wrong orientation as described in Example 19. The ANT expression cassette from this intermediate plasmid was then mobilized to the binary vector pMON36176 using the same procedure as described in Example 19, resulting in the construction of pMON57991. Example 21 The stored RNA is purified using Trizol reagent from Life Technologies (Gibco BRL, Life Technologies, Gaithersburg, Maryland U.S.A.), essentially as recommended by the manufacturer. Poly A+ RNA (mRNA) is purified using magnetic oligo dT beads essentially as recommended by the manufacturer (Dynabeads, Dynal Corporation, Lake Success, New York U.S.A.). Construction of plant cDNA libraries is well-known in the art and a number of cloning strategies exist. A number of cDNA library construction kits are commercially available. The Superscript™ Plasmid System for cDNA synthesis and Plasmid Cloning (Gibco BRL, Life Technologies, Gaithersburg, Maryland U.S.A.) is used, following the conditions suggested by the manufacturer. Example 22 For RNA preparation, the stored cotton tissue is grounded thoroughly in liquid nitrogen and then incubated with a high SDS solution (about 2.5% SDS by weight, 0.1 M Tris-HCl (pH7.5), 2.5 M sodium perchlorate, 0.1% b-mercaptoethanol by volume) and insoluble PNPP (about 8.5% by weight) for about 30 minutes at the room temperature. Nucleic acids are then precipitated after filtration. The total RNA is isolated from the precipitate using Trizol reagent from Life Technologies (Gibco BRL, Life Technologies, Gaithersburg, Maryland U.S.A.), essentially as recommended by the manufacturer. Poly A+ RNA (mRNA) is purified using magnetic oligo dT beads essentially as recommended by the manufacturer (Dynabeads, Dynal Corporation, Lake Success, New York U.S.A.).

The Superscript™ Plasmid System for cDNA synthesis and Plasmid Cloning (Gibco BRL, Life Technologies, Gaithersburg, Maryland U.S.A.) is used, following the conditions suggested by the manufacturer. Example 23 This example illustrates how rice BAC library is constructed and how BAC contigs are obtained. The rice BAC library may be constructed in the pBeloBACl l or similar vector. BAC vector, pBeloBACl l, is derived from the endogenous E. coli F-factor plasmid, which contains genes for strict copy number control and unidirectional origin of DNA replication. Additionally, pBeloBACll has three unique restriction enzyme sites {Hind III, Bam HI and Sph I) located within the E cZ gene which can be used as cloning sites for megabase-size plant DNA. Indigo, another BAC vector contains Hind III and Eco RI cloning sites. This vector also contains a random mutation in the LacZ gene that allows for darker blue colonies. Megabase-size DNA of high quality with minimal breakage can be prepared using protoplast method. The protoplast method involves preparing young leaves which are manually feathered with a razor-blade before being incubated for four to five hours with cell-wall- degrading enzymes and then isolating protoplasts. Megabase-size DNA may also be prepared using the universal nuclei method developed by Zhange et al. {Plant J. 7:175-184 (1995), herein incorporated by reference in its entirety). In the universal nuclei method, fresh or frozen tissue is homogenized with a blender or mortar and pestle and then nuclei are isolated. Once protoplasts or nuclei are produced, they are embedded in an agarose matrix as plugs or microbeads. The agarose provides a support matrix to prevent shearing of the DNA while allowing enzymes and buffers to diffuse into the DNA. The DNA is purified and manipulated in the agarose and is stable for more than one year at 4°C. Once high molecular weight DNA has been prepared, it is fragmented to the desired size range by partial restriction enzyme (e.g., Eco RI or other enzymes) digestion. The advantage of partial restriction enzyme digestion is that no further enzymatic modification of the ends of the restriction fragments are necessary. Four common techniques that can be used to achieve reproducible partial digestion of megabase-size DNA are 1) varying the concentration of the restriction enzyme, 2) varying the time of incubation with the restriction enzyme 3) varying the concentration of an enzyme cofactor {e.g., Mg 2+ ) and 4) varying the ratio of endonuclease to methylase. After partial digestion of megabase-size DNA, the DNA is run on a pulsed-field gel, and DNA in a size range of 100-500 kb is excised from the gel. This DNA is ligated to the BAC vector or subjected to a second size selection on a pulsed field gel under different running conditions. Studies have previously reported that two rounds of size selection can eliminate small DNA fragments co-migrating with the selected range in the first pulse-field fractionation. Such a strategy results in an increase in insert sizes and a more uniform insert size distribution. A practical approach to performing size selections is to first test for the number of clones/microliter of ligation and insert size from the first size selected material. If the numbers are good (500 to 2000 white colony/microliter of ligation) and the size range is also good (50 to 300 kb) then a second size selection is practical. When performing a second size selection one expects a 80 to 95% decrease in the number of recombinant clones per transformation. Twenty to two hundred nanograms of the size-selected DNA is ligated to dephosphorylated BAC vector (molar ratio of 10 to 1 in BAC vector excess). Most BAC libraries use a molar ratio of 5 to 15 : 1 (size selected DNA:BAC vector). Transformation is carried out by electroporation and the transformation efficiency for BACs is about 40 to 1,500 transformants from one microliter of ligation product or 20 to 1000 transformants/ng DNA. The quality of a BAC library can be assessed by determining the genome coverage of a BAC library-average insert size, average number of clones hybridizing with single copy probes, and chloroplast DNA content. The determination of the average insert size of the library is assessed in two ways. First, during library construction every ligation is tested to determine the average insert size by assaying 20-50 BAC clones per ligation. DNA is isolated from recombinant clones using a standard mini preparation protocol, digested with Not I to free the insert from the BAC vector and then sized using pulsed field gel electrophoresis (Maule, Molecular Biotechnology 9:107- 126 (1998), herein incorporated by reference in its entirety). To determine the genome coverage of the library, it is screened with single copy RFLP markers distributed randomly across the genome by hybridization. Microtiter plates containing BAC clones are spotted onto Hybond membranes. Bacteria from 48 or 72 plates are spotted twice onto one membrane resulting in 18,000 to 27,648 unique clones on each membrane in either a 4X4 or 5X5 orientation. Since each clone is present twice, false positives are easily eliminated and true positives are easily recognized and identified. Finally, the chloroplast DNA content in the BAC library is estimated by hybridizing three chloroplast genes spaced evenly across the chloroplast genome to the library on high density hybridization filters. A number of sequencing techniques are known in the art, including fluorescence-based sequencing methodologies. These methods have the detection, automation and instrumentation capability necessary for the analysis of large volumes of sequence data. Currently, the 377 DNA Sequencer (Perkin-Elmer Corp., Applied Biosystems Div., Foster City, CA) allows the most rapid electrophoresis and data collection. With these types of automated systems, fluorescent dye-labeled sequence reaction products are detected and data entered directly into the computer, producing a chromatogram that is subsequently viewed, stored, and analyzed using the corresponding software programs. These methods are known to those of skill in the art and have been described and reviewed (Birren et al, Genome Analysis: Analyzing DNA,1, Cold Spring Harbor, New York (1999), the entirety of which is herein incorporated by reference). PHRED is used to call the bases from the sequence trace files. Phred was developed at the Univerity of Washington and can be found by going to the university website, and searching for "phred". Quoting from their website, "Phred reads DNA sequencer trace data, calls bases, assigns quality values to the bases, and writes the base calls and quality values to output files. Phred can read trace data from SCF files and ABI model 373 and 377 sequencer chromat files, automatically detecting the file format. After calling bases, phred writes the sequences to files in either FASTA format, the format suitable for XBAP, PHD format, or the SCF format. Quality values for the bases are written to FASTA format files or PHD files, which can be used by the phrap sequence assembly program in order to increase the accuracy of the assembled sequence." Phred uses Fourier methods to examine the four base traces in the region surrounding each point in the data set in order to predict a series of evenly spaced predicted locations. That is, it determines where the peaks would be centered if there were no compressions, dropouts, or other factors shifting the peaks from their "true" locations. Next, PHRED examines each trace to find the centers of the actual, or observed peaks and the areas of these peaks relative to their neighbors. The peaks are detected independently along each of the four traces so many peaks overlap. A dynamic programming algorithm is used to match the observed peaks detected in the second step with the predicted peak locations found in the first step. After the base calling is completed, contaminating sequences (E. coli, BAC vector sequences > 50 bases and sub-cloning vector are removed and constraints are made for the assembler. Contigs are assembled using CAP3 (Huang, et al, Genomics 46: 37-45 (1997) the entirety of which is herein incorporated by reference). Example 24 This example illustrates how Agrobacterium cells are transformed and how transformed cells are cultured. Transformation: 1. Electroporate 2 μl of DNA construct into 20 μl of ABI competent cells; 2. Pipette transformed cells directly onto LB plates containing Spectinomycin (75μιg/ml), Kanamycin (50μg/ml), Chloramphenicol (25μg/ml). Add 50 μl of SOC media to plate and spread; 3. Incubate plated transformation at 28°C for 2 days (or can grow over weekend). ABI Cell Culture: 1. Pick 3 colonies per ABI plate and grow each in 4ml LB media containing Spectinomycin (75μg/ml), Kanamycin (50μg/ml), Chloramphenicol (25μg/ml); 2. Incubate 4 ml cultures of at 28°C, shaking, for 2 days, (culture tubes should be at an angle). Glycerol Stocks, & DNA Preps: 1. Make three 1 ml ABI glycerol stocks per 4 ml culture, using 500μl of culture and 500μl of 40%) glycerol. Freeze and store at -80°C. 2. Miniprep remaining culture (about 2.5ml), using a Qiagen miniprep kit and protocol (Qiagen Genomics, Inc., Seattle, WA), ensuring add PB buffer wash step and EB buffer (lOmM Tris- Cl, pH 8.5)_to 70°C before eluting DNA from column. The resulting volume per miniprep sample should be 50μl. Digest Confirmation: 1. Using the Pollux and construct maps,determine whether the plasmids transformed into the bacteria are, in fact, the plasmids transformed. Restriction enzymes are selected that allow this by finding appropriate enzymes that cut in both the insert and the plasmid and allow the discrimination of this specific plasmid from some or all others. 2. Digest 17μl miniprep DNA per digest, resulting in a final digest volume of 20μl; 3. Run 20μl of each digest on 1% agarose gel vs. 1Kb DNA ladder; and 4. For 2 of 3 confirmed clones, streak LB plates containing Spectinomycin (75μg/ml), Kanamycin (50μg/ml), Chloramphenicol (25μg/ml) from ABI glycerol stocks and allow to grow at 28°C for 2 days (or can grow over weekend). Sequencing for insert verification (as an alternative to, or in addition to, digest confirmation): 1. In addition to the above digest confirmation, it would be possible to confirm the insert integrity and type by DNA sequencing. 2. A DNA primer would be selected 50-500 base pairs from the junction between the plasmid (backbone) DNA and the insert DNA. Said primer's 3' end would face toward the insert, 3. An appropriate DNA sequencing reaction and read on a poly acrylamide gel or other column could be used to determine the sequence of the DNA. 4. One would specifically look for the DNA sequence at the junction to determine whether said sequence was appropriate and determine whether sequence of said insert was as the researcher expected. Example 25 Arabidopsis plants may be transformed by any one of many available methods. For example, Arabidopsis plants may be transformed using In planta transformation method by vacuum infiltration (see, Bechtold et al, In planta Agrobacterium mediated gene transfer by infiltration of adult Arabidopsis thaliana plants. CR Acad. Sci. Paris Sciences de la vie/life sciences 316: 1194-1199 (1993), herein incorporated by reference in its entirety). This example illustrates how Arabidopsis plants are transformed. Stock Plant Material and Growth Conditions Prepare 2.5 inch pots with soil and cover them with a mesh screen, making sure that the soil is not packed too tightly and the mesh is in contact with the soil surface (this ensures that the germinating seedlings will be able to grow through the mesh). Sow seeds and cover with a germination dome. Vernalize seeds for 3-4 days. Grow plants under conditions of 16 hours light / 8 hours dark at 20-22° C, 70%> humidity. Water twice weekly, and fertilize from below with 1/2 X (half of the strength recommended by the manufacturer) Peters 20-20-20 fertilizer (from Hummert International, Earth City, MO). Add micronutrients (Hummert's Dyna-grain Soluble Trace Elements) (in full strength recommended by the manufacturer) every other week. After about 1-2 weeks, remove the dome and thin the pots to one or two plants per pot. Clip the primary bolt, when it develops, to encourage more secondary bolt formation. In 5-7 days the plants will be ready for infiltration. Agrobacterium Preparation (Small scale and Large scale cultures): Agrobacterium strain ABI is streaked onto an LB plate containing Spectinomycin 100 mg/L, Streptomycin 100 mg/L, Chloramphenicol 25mg/L, and Kanamycin 50mg/L (denoted SSCK). Two days prior to infiltration, a loop of Agrobacterium is placed into a tube containing 10 mis LB/SSCK and put on a shaker in the dark at 28°C to grow overnight. The following day, the Agrobacterium is diluted 1:50 in 400 mis YEP/SSCK and put on a shaker at 28°C to grow for 16-20 hours. (Note: we have found the transformation rate is significantly better when LB is used for the first overnight growth and YEP is used for the large scale overnight culture). Infiltration Harvest the Agrobacterium cells by pouring into a 500 ml centrifuge bottle and spinning at 3500 rpm for 20-25 minutes. Pour off the supernatant. Dry the pellet and then resuspend in 25 ml Infiltration Medium (MS Basal Salts 0.5%, Gamborg's B-5 Vitamins 1%, Sucrose 5%, MES 0.5 g/L, pH 5.7) with 0.44 nM benzylaminopurine (BAP) (10 μl of a 1.0 mg/L stock in DMSO per liter) and 0.02% Vac-In-Stuff (Silwet L-77) from Lehle Seeds (Round Rock, TX). The BAP and Silwet L-77 are added fresh the day of infiltration. Add 200 μl of Silwet L-77, and 20 μl of BAP (0.5 mg/L stock). Using Infiltration Medium as your blank, take the OD 6 oo of a 1:10 dilution of the Agrobacterium suspensions. Calculate the volume needed for 400 ml of Agrobacterium suspension/infiltration medium, OD600 = 0.6, for the vacuum infiltration. Equation: (final volume * (final OD600) = Volume needed for final OD600 of 0.6 OD600 Place resuspended culture in a Rubbermaid container inside a vacuum dessicator. Invert pots containing plants to be infiltrated into the solution so that the entire plant is covered, including the rosette, but not too much of the soil is submerged. Soak the plants with water for at least 30 min. prior to infiltration. (This keeps the soil from soaking up the Agrobacterium suspension). Draw a vacuum of- 23-27 in. Hg for 10 min. Quickly release the vacuum. Briefly drain the pots, place them on their sides in a diaper-lined tray, cover the tray with a dome to maintain humidity, and return to growth chamber. The following day, uncover the pots, set them upright, and remove the diaper. Do not water plants for ~ 5 days. After the 5 days are up, allow the plants to be watered and to continue to grow under the same conditions as before. (The leaves that were infiltrated may degenerate but the plant should survive until it is finished flowering). Harvesting and Sterilizing Seed Cone the plants, individually, by using the Lehle Aracons (Lehle Seeds, Round Rock, TX) approximately 2 weeks after infiltration. After all of the seed is matured and has set (~ 4 weeks post-infitration), remove the plants from water to dry down the seeds. Approximately 2 weeks later harvest the seeds by cutting the branches below the cone. Clean the seed by using a sieve to catch the silique and branch material and allow the seed to go through. Place the seed in an envelope or in 15ml conical tubes. Transfer desired amount of seeds to 15ml conical tubes prior to sterilization. Loosen the lid to the conicals and place them on their side in a vacuum dessicator with a beaker containing 400 ml of bleach Clorox (Clorox Company, Oakland, CA) and 4 ml of Hydrochloric Acid. (Add the HCl to the Clorox in a fume hood). Pull a vacuum just to seal the dessicator, and close the suction (i.e. so that the dessicator is still under a vacuum but the vacuum is not still being directly pulled) for ~ 16 hrs. After sterilization, release the vacuum and place tubes containing seed in a sterile hood (keep caps loose so gas can still be released). Plate ("sprinkle") the seed on selection plates containing MS Basal Salts 4.3 g/L, Gamborg'a B-5 (500 X) 2.0 g/L, Sucrose 10 g/L, MES 0.5 g L, and 8 g/L Phytagar (Life Technologies, Inc., Rockville, MD) with Carbenicillin 250mg/L, Cefotaxime 100 mg/L. Selection levels will either be kanamycin 60 mg/L, Glyphosate 60μM, or Bialaphos lOmg/L. A very small amount of seed can be first plated out to check for contamination. If there is contamination, re-sterilized seeds for ~ 4 more hours and check for contamination again. The second sterilization is usually not necessary, but sometimes the seed harbors a fungal contaminant and repeat sterilizations are needed. (The sterilization duration generally is shorter than 16 hours because of significantly decreased germination rates starting at 24 hr. sterilization duration). Seal plates with parafilm and place in a cold room to vernalize for ~ 2-4 days. After seeds are vernalized, place in percival with cool white bulbs. Transfer to Soil After 5-10 days at -26° C and a 16/8 light cycle, the transformants will be visible as green plants. After another 1-2 weeks, plants will have at least one set of true leaves. Transfer plants to soil, cover with a germination dome, and move to a growth chamber with normal Arabidopsis growth conditions. Keep covered until new growth is apparent (usually 5-7 days). Example 26 This example illustrates how the shoot biomass of Arabidopsis plants can be increased by ectopically expressing the crop ^ 4NE-like genes in transgenic Arabidopsis plants. The soybean NE-like genes, GmANTl and GmANT2, which were identified and cloned according to the procedure described in Example 1, were constructed into a binary vector for transgenic expression under the control of the CaMN e35S promoter, as described in Examples 9 and 10, respectively. The rice AΝT-like gene, OsANTl, which was identified and cloned according to the procedure described in Example 2, was constructed into a binary vector for transgenic expression under the control of the CaMV e35S promoter, as decribed in Example 18. The Arabidopsis ANT gene was cloned and constructed into a binary vector for the Agrobacterium-mediated transformation and constitutive expression of ANT in Arabidopsis plants under the control of the CaMN e35S promoter, as described in Examples 7 and 8. Agrobacterium transformation with the above constructed vectors were carried out according to the protocol described in Example 24. Arabidopsis transformation and subsequent generation of transgenic plants were performed as described in Example 25. Tl seeds of the transgenic plants were sowed in potted soil along with wild-type plants (controls), and were vernalized for three days before moving to a growth chamber. The plants were grown under the following conditions: at 22°C, 24 hours constant light with light intensity of 170-200 μm Einstein m ' V 1 , and a humidity of 70%. Plants were also grown under short day conditions, with 10 hours of light period. Plants were fertilized twice a week using Peters 20-20- 20 fertilizer (in half strength) from Hummert International, Earth City, MO). Plants were monitored for both vegetative and reproductive growth. Under both long day and short day conditions, the transgenic plants expressing the Arabidopsis ANT had similar above ground vegetative vigor as the wild-type control plants. However, the transgenic plants expressing the crop AΝT-like genes had more vigorous shoot growth. For example, under short day growth conditions, the leaf area of transgenic plants expressing the rice OsANTl was increased by 40% at day 42. Example 27 This example illustrates that the ectopic expression of Arabidopsis ANT and the crop AΝT-like genes in Arabidopsis transgenic plants resulted in increase in the growth and biomass of roots. Previous studies have suggested that the ectopic expression of the Arabidopsis ANT had no effect on root development of transgenic plants (Krizek, Developmental Genetics 25: 224-236 (1999); Y Mizukami and R L Fischer, Proc. Νatl. Acad. Sci. 97: 942-947 (2000); both of which are herein incorporated by reference in their entirety). The data included herein suggests that the ectopic expression of the Arabidopsis ANT as well as other crop AΝT-like genes can cause increase in root growth. Transgenic plants expressing the Arabidopsis AΝT and those expressing the rice OsANTl, both driven by the e35S promoter, were produced as described in Example 26. In addition, transgenic plants expressing the AΝT driven by the root-specific promoter, Rb7, were also produced as described in Examples 16, 24 and 25. The seeds were harvested for further planting and transgenic analysis. To prepare the plates for germination, 3.54 gram of the MS plant tissue culture medium (Sigma, St Louis, MO) and 0.5 gram sucrose was dissolved in one liter of deionized water, pH adjusted to 5.8 with KOH, 8 gram Phytagar (GIBCO) added before autoclaving for 21 min, followed by distributing to 9x9 cm square petri dish plates, with 35 ml per plate. To sow the seeds onto the plate, seeds were sterilized in 70% ethanol for 2 min and then in 30%> commercial bleach, 0.01%) Triton X-100 for 3 minutes, followed by 4 washes in sterile water. The sterilized seeds were laid onto the plate, which were vernalized at 4°C for 3 days before moving to the growth chamber as described in Example 26. The plates were set up in vertical position, and the root and shoot growth rate were monitored daily upon germination. Comparison of the transgenic seedlings with the wild-type demonstrates that the roots of transgenic plants were longer and bigger, and the leaves apparently more green. For example, at the fourth day after germination, the roots of the transgenic lines were about 20-40% longer than the wild-type control on the same plate. Table 5. Root length of transgenic and normal plants. Example 28 This example illustrates that the ectopic expression of ANT and ANT-like genes in transgenic Arabidopsis plants can result in increased floral organ size. Transgenic plants expressing the Arabidopsis ANT, as well as those expressing the soy GmANTl and GmANT2, all driven by the CaMN e35S promoter, were produced according to the procedures as described in Example 26. In addition, transgenic plants expressing AΝT driven by the SSUIA promoter were also produced as described in Examples 14, 24 and 25. The seeds were harvested for line advancement and further transgenic analysis. The floral organ size was measured and compared to that of wild-type plants. The results showed that transgenic plants had larger floral organs than wild-type plants. For example, the petal size of transgenic plants expressing the soy GmANTl driven by the CaMN e35S promoter was increased by up to 100% compared to that of wild-type plants, while the petal size of transgenic plants expressing AΝT driven by the SSUIA promoter was increased by 75%. Increased floral organ size can be useful in the flower industry, to produce larger flowers in roses and other commercially important flowers. Increased floral organ size can also be important as larger flowers in some plants lead to larger seeds and/or fruits. Table 6. Petal size in transgenic and normal plants. Petal size % (U) increases WT 13328+/-730 0 GmANTl 27429+A889 106 Example 29 This example illustrates that the conditional expression of ANT and the ectopic expression of the crop ANT-like genes can result in increased seed size. Transgenic plants expressing ANT under the control of the e35S promoter and the SSUIA promoter were produced as described in Example 28; transgenic plants expressing the soy GmANTl and GmANT2 were produced as described in Example 28; transgenic plants expressing the rice OsANTl were produced as described in Example 26. In all cases, transgenic plants with seeds larger than the wild-type were obtained. Furthermore, the big seed phenotype was transmitted to the next generation, at least for the transgenic plants expressing ANT from the SSUIA promoter that we have tested. For example, the size of N3 seeds of transgenic plants expressing AΝT from SSUIA were increased by 27%. Increased seed size leads to greater yield in many economically important crop plants. Increased seed size is thus one goal of genetically engineering and selection. Table 7. Seed size in transgenic and normal plants. Example 30 This example illustrates that the conditional expression of ANT and the crop ANT-like genes can increase the seed oil content. Transgenic plants expressing the ANT from the seed-specific Napin promoter were produced as described in Examples 13, 24 and 25. Biochemical analysis of the seeds from the transgenic plants showed that the seed oil content was increased compared to the wild-type control. For example, the oil content of V3 seeds tested was increased by 16%> when compared to the wild-type control. Increased oil content is also a measure of yield in many economically important plants. Soybean, com, canola and other plant oils are economically important thus increasing amount of oil per seed is advantageous. Table 8. Percentage of oil in seed of transgenic and normal plants. Example 31 This example illustrates that the conditional expression of ANT and the crop ANT-like genes can increase the seed yield. Transgenic plants expressing the ANT gene from the seed-specific Napin promoter were produced as described in Examples 13, 24 and 25. Transgenic plants were grown in controlled conditions along with wild-type plants, as described in Example 26. Seeds were harvested from individual plants at maturity. Analysis shows that the seed weight per plant was increased compared to the wild-type control. For example, the seed weight of the 1A2_V4 line was increased by 35% when compared to the wild-type control. Weight of seeds is an important characteristic of seed in crop plants, as plants that produce more seed are more desirable that those that those that produce less seed. Table 9. Seed yield increase by transgene ANT driven by the Napin promoter Example 32 In order to determine how the expression of ANT genes can affect characteristics of com, com was transformed with the ANT gene containing constructs driven by the rice actin and pox- 1 promoters. The construct containing the rice actin promoter was rACTl-ANT is pMON57988 (see Example 19). The construct containing poxl-ANT was pMON57991 (see Example 20). Transgenic corn plants were produced by an Agrobacterium mediated transformation method. Disarmed Agrobacterium strain C58 (ABI) harboring vectors of the present invention was used for all the experiments. The DNA construct is transferred into Agrobacterium by a triparental mating method (Ditta et al, Proc. Natl. Acad. Sci. 77:7347-7351). Agrobacterium ABI in glycerol stock is streaked out on solid LB medium supplemented with the antibiotics kanamycin (50mg/L), spectinomycin (100 mg/L), streptomycin (100 mg/L) and chloramphenicol (25 mg/L) and incubated at 28 °C for 2 days. Two days before Agrobacterium inoculation, one colony from the Agrobacterium plate is picked up and inoculated into 25 mL of liquid LB medium supplemented with 100 mg/L each of spectinomycin and kanamycin in a 250-mL flask. The flask is placed on a shaker at approximately 150 rpm and 27°C overnight. The Agrobacterium culture is then diluted (1 to 5) in the same liquid medium and put back to the shaker. Several hours later in the late afternoon one day before inoculation, the Agrobacterium cells are spxm down at 3500 rpm for 15 min. The bacterium cell pellet is resuspended in induction broth with 200 μM of acetosyringone and 50 mg/L spectinomycin and 25 mg/L kanamycin and the cell density is adjusted to 0.2 at O.D. 66 o. The bacterium cell culture (50 mL in each 250-mL flask) is then put back to the shaker and grown overnight. In the morning of inoculation day, the bacterium cells are spun down and washed with liquid 1/2MS VI medium (Table 1) supplemented with 200 μM of acetosyringone. After one more spinning, the bacterium cell pellet is re-suspended in Vi MS PL medium (Table 1) with 200 μM of acetosyringone (Table 1), and the cell density is adjusted to 1.0 at O.D 66 o for inoculation. After resuspension, the Agrobacterium can be stored at 4°C for up to 27 days and used as desired. Reagents are commercially available and can be purchased from a number of suppliers (see, for example Sigma Chemical Co., St. Louis, MO).

The tube is then set aside for 5 min. After the Agrobacterium suspension is removed using a transfer pipet with fine tip, the embryos are transferred to standard co-culture medium (Table 1). The embryos are placed with the scutellum side facing up. The embryos are cultured in a Percival incubator set at 23°C and dark for approximately 24 h. Selection and regeneration and growth: After the co-cultivation, the embryos are transferred from the co-culture plates onto callus induction medium, LH172 MS (Table 1) with 500 mg/L carbenicillin and 100 or 200 mg/L paromomycin. The plates are kept in a dark culture room at 27°C for approximately 2 weeks. Two weeks later, almost all the callus pieces developed individually are transferred onto MS6BAP (Table 1) with 250 mg/L carbenicillin and 100 or 200 mg/L paromomycin. The plates are kept in a culture room with 16-h light and at 27°C for 5-7 days. Then, the callus pieces are transferred onto MSOD (Table 1) with 250 mg/L carbenicillin and 100 or 200 mg/L paromomycin. In another 2 weeks, all the pieces with shoots or living tissue are transferred onto the same media in phytatrays for further growth. When the plantlets reach the lid and have a few roots, they are moved to soil in peat pots in a growth chamber. In 7 to 10 days, they are transplanted into 12-in pots and moved to the greenhouse with conditions for normal com plant growth. Example 33 The expression of an exogenous Arabidopsis ANT gene in corn plants. For expression of ANT in com, two promoters were used. One was the largely constitutive rice actin promoter (US patent 5,641 ,876), and the other the root-enhanced poxl promoter (Hertig, et al., Plant Molecular Biology 16:171). Both constructs included the 3' termination sequence from the E9 gene. The construct containing rACTl-ANT is pMON57988 (see Example 19). The construct containing poxl-ANT is pMON57991 (see Example 20). DNA of each plasmid was introduced into an Agrobacterium strain (ABI) by electroporation. Plants containing rACTl-ANT (pMON57988) were named Abby, and plants with the poxl-ANT construct were named Anny (pMON57991). Expression of the ANT gene in leaves of R0 plants (V6 - V8 stage) was analyzed using Taqman to determine levels of mRNA. Taqman is a real time sequence detection system supplied by Applied Biosystems. Taqman allows the real time quantitative determination of levels of PCR product present. In this specific case we used primers to detect the E9 termination region in order to determine expression levels. The specific primers used were: forward primer = CAACGTTCGTCAAGTTCAATGC (SEQ ID NO: 20) reverse primer - TGCCATAATACTCGAACTCAGTAGGA (SEQ ID NO: 21) probe = 6FAM-TCAGTTTCATTGCGCACACACCAGAA-TAMRA. (SEQ ID NO: 22) The FAM and TAMRA are fluorescent based dyes. The FAM is the reporter dye and the TAMRA is the quencher. Further details of the Taqman assay are available from the manufacturer (Applied Biosystems, Foster City, CA). Expression levels in transgenic plants were compared to those in a wild type control. The average relative expression compared to wild type for Abby events selected for further study ranged from 1558 to 42,027, and for Anny ranged from 739 to 6002. The lower expression in Anny was expected as in these events the ANT gene is driven by the root-enhanced promoter (and leaf tissue was analyzed). For Abby, 26 transgenic lines were selected from 37 lines. For Anny, 19 transgenic were selected from 33 R0 lines. The R0 plants were selfed to generated RI seed, and also crossed to a wild type LH172 (a specific inbred line of com available from Holden) to generate FI seed. RI seed of these events was planted in a field near Jerseryville, IL in May 2001. However, the plants were lost in a windstorm. Therefore, seed was planted in a field the Kihei, HI in August 2001 for observation and advancement to the next generation. Seed availability reduced the number of events planted to 19 for Abby, and 11 for Anny. The seed used was from a cross wherein the transgene was segregating to some offspring, but not all, thus 24 plants per row were labeled, and leaf tissue was harvested, DNA produced, and PCR was done to determine presence or absence of the gene by PCR of the E9 3' end (in a manner similar to the Taqman protocol above, using the same primers). Height of plants at the time of silking was measured (distance from soil to the collar of the flag leaf) (see example 34). Further observations are planned. Seed and ear specific traits include row number, 100- kernel weight (kernels taken from the middle of the cob), and cob length. All measurements will be correlated with presence or absence of the ANT gene. Events that demonstrate a 1 :1 segregation of the transgene will be advanced to the next generation. The next steps for these events are to determine effects of the ANT gene on plant growth and development. For the poxl-ANT events, FI seed will be germinated in the dark on rolled blotter paper at 25 °C for 5 to 7 days. Root length will be measured, and samples will be taken for PCR analysis of the transgene. We expect that plants that express the Arabidopsis ANT under a root specific promoter will have longer roots. For the constitutive rACTl promoter, we plan to generate homozygous lines before conducting further phenotype analysis. PCR-positive F2 ears (2 per event) will be selected for advancement, and. seed will be planted in Hawaii in December 2001. DNA Taqman (Applied Biosystems, Foster City, CA) will be used to determine zygosity of plants in the row (24 plants per event). All plants will be selfed. Homozygous positive and homozygous negative lines will be selected for further study. The constitutive promoter will be used to determine the effect of ANT on size of vegetative and reproductive organs. Production of larger seeds may increase yield. Alternatively, production of larger leaves may increase yield by providing more source capacity, and stimulation of root growth could provide more mineral nutrients or water to increase kernel production. The root-enhanced promoter was used to determine whether the ANT gene can promote production of bigger roots that would enable the plant to more readily obtain mineral nutrients and water. When homozygous lines are available, 12 plants per selection will be planted in a greenhouse, and the following measures will be taken: - Height will be measured each week until tasseling (see example 34 and 26). - Length of selected leaves will be measured (see example 26). - Flowering time will be recorded (see example 28). - Female and male reproductive structures of plants will be examined (see example 28). Comparisons will be made between plants that contain the said transgene(s) and the negative isolines. Root length of these selections will be measured by growing plants on the rolled blotter paper, as described for the poxl-ANT plants (see example 27 of RB7-ANT plants). We expect all of the above traits could be affected in a positive, yield enhancing direction by the expression of the ANT gene(s), as were the Arabidopsis plants in prior examples. Example 34 Aintegumenta expression in corn. Names of specific treansgenic lines may be defined elsewhere (i.e. Abby and Anny are defined in Example 33.). FI com plants containing ANT constructs were analyzed for final plant height, and seed return. It was not possible to measure other kernel and ear traits because of the highly variable rate of seed set on all the inbred ears from the nursery. No effect of the ANT gene on final plant height was observed (data not shown). However, an effect on fertility was seen with constitutive expression of ANT (Abby). Plants that contained the constitutive ANT construct did not produce seed as frequently as negative segregants. As a result, the proportion of plants with this construct (Abby) that contained the transgene was reduced in the population that produced seed, compared to the original plants in the row (Table 11). In contrast, the proportion of plants with the transgene was the same in these two populations for plants transformed with other constructs, including root-enhanced expression of ANT (Anny), and constructs containing other transegenes. These data suggest that expression of the ANT gene in reproductive organs has a negative effect on fertility. This result is consistent with the report that most Arabidopsis plants with a 35S::ANT transgene were sterile (Mizukami and Fischer, 2000), and suggests that the Arabidopsis ANT gene is having a similar effect in com as in Arabidopsis. This gene may be useful to enhance sink potential in com, using promoters that target dividing endosperm cells, but that avoid expression in certain reproductive tissues. The Anny plants will be useful to determine the effect of ANT on root growth in corn. An example of root growth in Arabidopsis is seen in Example 27. Table 11. Proportion of plants that contained the transgene is reduced in Abby population which produced seed, compared to all Abby plants in the row. Abby, ractl-ANT; Anny, poxl-ANT. Example 35 In addition to the methods mentioned above and below, recombinant DNA constructs designed for the expression of ANT could be transformed into com or other crops. A number of methods that would allow this exist. A DNA construct is transformed into a target crop of interest via an appropriate delivery system such as an Agrobacterium-mediated transformation method (see for example U. S. Patent No. 5,569,834 herein incorporated by reference in its entirety, U. S. Patent No. 5,416,011 herein incorporated by reference in its entirety, U. S. Patent No. 5,631,152 herein incorporated by reference in its entirety, U. S. Patent No. 5,159,135 herein incorporated by reference in its entirety, U. S. Patent No. 5,004,863 herein incorporated by reference in its entirety, and U. S. Provisional Appln. No. 60/111795 herein incorporated by reference in its entirety. Alternatively, a particle bombardment method may be used (see for example Patent Applns. WO 92/15675. WO 97/48814 and European Patent Appln. 586,355, and U. S. Patent Nos. 5,120,657, 5,503,998, 5,830,728 and 5,015,580, all of which are herein incorporated by reference in their entirety). A large number of transformation and regeneration systems and methods are available and well-known to those of skill in the art. The stably transformed plants and progeny are subsequently analyzed for expression of the gene in tissues of interest by any number of molecular, immunodiagnostic, biochemical, and or field evaluation methods known to those of skill in the art, including, but not limited to looking at any of a large number of phenotypic and physiologic traits (as in above examples; also transcriptional profiling; metabolic profiling, and others) in transformed plants and comparing them to plants transformed with different genes or non-transformed plants. For example, a rice (or other monocot) ANT gene under a plant promoter could be transformed into co , or another crop plant, to look at effects of monocot ANT genes in other monocots, or dicot ANT gene in other dicots, or monocot genes in dicots, or vice versa. The plasmids containing these ANT coding sequences, 5' of a promoter and 3' of a terminator would be constructed in a manner similar to those described for construction of other plasmids herein. Any number of promoters might be looked at, from tissue specific promoters, to constitutive promoters, to tissue-enhanced promoters, to myriad others within or without one of these groups. Example 36 Construction of pMON71250. ρMON71250 (Figure 19) is a bombardment construct with the rice ANTI {OsANTl) gene under the control of the Zea mays L3 (oleosin) promoter (Lee WS. et al., Proceedings of the National Academy of Science (USA) 88:6181, 1991; Lee K. et al., Plant Molecular Biology, 26:1981, 1994; Qu et al., Plant Science 72:223, 1990) for tissue-specific expression in com germ and aleurone. The OsANTl gene was PCR amplified using primers OsANTF (GGCGCGCCACAATGGCCAGCGGCGGCGGCAG SEQ ID NO: 32) and OsANTR (CCTGCAGGTCAGGCATCTGTCCAGGCTGCAA SEQ ID NO: 33) that contain Ascl and Sse838Α, respectively. The PCR amplification included an initial denaturation step of 94°C for 2 min followed by 30 cycles at 94°C for 30 sec, 58°C for 15 sec, 72°C for 1 min. The PCR product was cloned, sequencing confirmed, and subcloned into the Ascl and Sse838Λ sites of L3 expression vector pMON71050 (see attached Pollux map). The resulting construct pMON71250 was confirmed by restriction mapping and junction sequencing. The Mlul fragment containing the OsANTl cassette was purified for corn transformation via bombardment into the LH59 corn line. Example 37 Methods of microprojectile bombardment Approximately four hours prior to microprojectile bombardment, LH59 immature embryos were transferred to medium 211SN (Ν6 salts with 12% sucrose at pH 5.8, 1 mg 2,4-D, 17 mg AgNO.sub.3, 1 mg thiamine HCl, 690 mg proline, 900 mg asparagine, 100 mg casamino acids, 500 mg MES). Twenty-five immature embryos were preferably placed in a 60 x 15 mm petri dish, arranged in a 5 x 5 grid with the coleoptilar end of the scutellum pressed slightly into the culture medium at a 20 degree angle. Tissue was maintained in the dark prior to bombardment. Prior to microprojectile bombardment, a suspension of gold particles was prepared onto which the desired DNA was precipitated. Ten milligrams of 0.6 μm gold particles (BioRad) were suspended in 50 μL buffer (150 mM NaCl, 10 mM Tris-HCl, pH 8.0). Twenty five μL of a 2.4 nM solution of the desired DNA was added to the suspension of gold particles and gently vortexed for about five seconds. Seventy five μL of 0.1M spermidine was added and the solution vortexed gently for about 5 seconds. Seventy five μL of a 25% solution of polyethylene glycol (3000-4000 molecular weight, American Type Culture Collection) was added and the solution was gently vortexed for five seconds. Seventy five μL of 2.5 M CaCl 2 was added and the solution vortexed for five seconds. Following the addition of CaCl 2 , the solution was incubated at room temperature for 10 to 15 minutes. The suspension was subsequently centrifuged for 20 seconds at 12,000 rpm (Sorval MC-12V centrifuge) and the supernatant discarded. The gold particle/DNA pellet was washed twice with 100% ethanol and resuspended in 10 mL 100% ethanol. The gold particle/DNA preparation was stored at -20°C for up to two weeks. DNA was introduced into maize cells using the electric discharge particle acceleration gene delivery device (US Patent No. 5,015,580). The gold particle/DNA suspension was coated on Mylar sheets (Du Pont Mylar polyester film type SMMC2, aluminum coated on one side, over coated with PVDC co-polymer on both sides, cut to 18 mm square) by dispersion of 310 to 320 μL of the gold particle/DNA suspension on a sheet. After the gold particle suspension settled for one to three minutes, excess ethanol was removed and the sheets were air dried. Microprojectile bombardment of maize tissue was conducted as described in U.S. Patent No. 5,015,580. AC voltage may be varied in the electric discharge particle delivery device. For microprojectile bombardment of LH59 pre-cultured immature embryos, 35% to 45%> of maximum voltage was preferably used. Following microprojectile bombardment, tissue was cultured in the dark at 27°C. Selection of transformed cells Transformants were selected on culture medium comprising paromomycin, based on expression of a transgenic neomycin phosphotransferase II {nptlϊ) gene. Twenty four hours after DNA delivery, tissue was transferred to 211V medium containing 25 mg/L paromomycin (medium 211HV). After three weeks incubation in the dark at 27°C, tissue was transferred to medium 211 containing 50 mg/L paromomycin (medium 21 IG). Tissue was transferred to medium 211 containing 75 mg/L paromomycin (medium 211XX) after three weeks. Transformants were isolated following 9 weeks of selection. Regeneration of fertile transgenic plants Fertile transgenic plants were produced from transformed maize cells. Transformed callus was transferred to medium 217 (N6 salts, 1 mg/L thiamine-HCl, 0.5 mg/L niacin, 3.52 mg/L benzylaminopurine, 0.91 mg/L L-asparagine monohydrate, 100 mg/L myo-inositol, 0.5 g/L MES, 1.6 g/L MgCl 2 -6H 2 O, 100 mg/L casein hydrolysate, 0.69 g/L L-proline, 20 g/L sucrose, 2 g/L GELGRO™, pH 5.8) for five to seven days in the dark at 27°C. Somatic embryos mature and shoot regeneration began on medium 217. Tissue was transferred to medium 127T (MS salts, 0.65 mg/L niacin, 0.125 mg/L pyridoxine-HCl, 0.125 mg/L thiamine-HCl, 0.125 mg/L Ca pantothenate, 150 mg/L L-asparagine, 100 mg/L myo-inositol, 10 g/L glucose, 20 g/L L-maltose, 100 mg/L paromomycin, 5.5 g PHYTAGAR™, pH 5.8) for shoot development. Tissue on medium 127T was cultured in the light at 400-600 lux at 26°C. Plantlets are transferred to soil, preferable 3 inch pots, about four to 6 weeks after transfer to 127T medium when the plantlets are about 3 inches tall and have roots. Plants were maintained for two weeks in a growth chamber at 26°C, followed by two weeks on a mist bench in a greenhouse before transplanting to 5 gallon pots for greenhouse growth. Plants were grown in the greenhouse to maturity and reciprocal pollinations were made with the inbred LH59. Seed was collected from plants and used for further breeding activities and future testing. Planned future experiments Transgenic com data from first generation seed for pMON71250 is expected by the second quarter of 2002 and second generation data is expected by the end of 2002. First generation seed and dissected parts (germ and endosperm) will be analyzed by bench-top NMR and kernels harboring the transgene will be identified by PCR. Germ mass will be determined as part of this analysis. Differences in whole kernel %> oil, germ % oil, endosperm %> oil, germ and endosperm mass will be determined in a comparison between kernels harboring the transgene (identified by PCR) and null segregants (lacking the transgene). Analysis for protein and starch content may also be undertaken. Transgenic kernels will be analyzed for gross morphological differences, and kernels from different developmental stages may be sectioned (manually or optically) to detect morphological changes.
