FIELD OF THE INVENTION
This invention is directed to plant genetic engineering. It relates to, for example, modulating seed (and in particular endosperm, embryo and seed coat) development, flowering time, chromosomal DNA methylation and modulating transcription in plants.
BACKGROUND OF THE INVENTION
A fundamental problem in biology is to understand how seed development. In flowering plants, the ovule generates the female gametophyte, which is composed of egg, central, synergid and antipodal cells (Reiser, et al., Plant Cell, 1291–1301 (1993)). All are haploid except the central cell which contains two daughter nuclei that fuse prior to fertilization. One sperm nucleus fertilizes the egg to form the zygote, whereas another sperm nucleus fuses with the diploid central cell nucleus to form the triploid endosperm nucleus (van Went, et al., Embryology of Angiosperms, pp. 273–318 (1984)). The two fertilization products undergo distinct patterns of development. In Arabidopsis, the embryo passes through a series of stages that have been defined morphologically as preglobular, globular, heart, cotyledon and maturation (Goldberg, R. B., et al., Science (1994) 266: 605–614; Mansfield, S. G., et al., Arabidopsis: An Atlas of Morphology and Development, pp. 367–383 (1994)). The primary endosperm nucleus undergoes a series of mitotic divisions to produce nuclei that migrate into the expanding central cell (Mansfield, S. G., et al., Arab Inf Serv 27: 53–64 (1990); Webb, M. C., et al, Planta 184:187–195 (1991)). Cytokinesis sequesters endosperm cytoplasm and nuclei into discrete cells (Mansfield, S. G., et al., Arab Inf Serv 27:65–72 (1990)) that produce storage proteins, starch, and lipids which support embryo growth (Lopes, M. A. et al., Plant Cell 5:1383–1399 (1993)). Fertilization also activates development of the integument cell layers of the ovule that become the seed coat, and induces the ovary to grow and form the fruit, or silique, in Arabidopsis. 
Of particular interest are recent discoveries of genes that control seed, and in particular endosperm, development. For instance, MEDEA (MEA) (also known as FIE1 (see, e.g., copending U.S. patent application Ser. No. 09/071,838) and F644 (see, e.g., Kiyosue T, et al. (1999) Proc Natl Acad Sci U.S.A 96(7):4186–91) encodes an Arabidopsis SET domain polycomb protein that appears to play a role in endosperm development. Inheritance of a maternal loss-of-function mea allele results in embryo abortion and prolonged endosperm production, irrespective of the genotype of the paternal allele. Thus, only the maternal wild-type MEA allele is required for proper embryo, endosperm, and seed coat development (Kinoshita T, et al. (1999) Plant Cell 10:1945–52). These results reveal functions for plant polycomb proteins in the suppression of central cell proliferation and endosperm development (Kiyosue T, et al. supra).
Another gene product that controls seed development is FIE, also known as FIE3 (see, e.g., copending U.S. patent application Ser. No. 09/071,838). The FIE protein is a homolog of the WD motif-containing Polycomb proteins from Drosophila and mammals (Ohad, N. et al. Plant Cell 11(3):407–16 (1999)). In Drosophila, these proteins function as repressors of homeotic genes. Loss of function mutations in the FIE gene result in endosperm phenotypes that are identical to medea loss of function mutations. A female gametophyte with a loss-of-function allele of fie undergoes replication of the central cell nucleus and initiates endosperm development without fertilization. These results suggest that the FIE Polycomb protein functions to suppress a critical aspect of early plant reproduction, namely, endosperm development, until fertilization occurs. Moreover, hypomethylation of fie mutants leads to the development of differentiated endosperm. Vinkenoog et al., Plant Cell 12:2271–2282 (2000).
Control of the expression of genes that control egg and central cell differentiation, or those that control reproductive development, i.e. embryo, endosperm and seed coat, is useful in the production of plants with a range of desired traits. These and other advantages are provided by the present application.

DEFINITIONS
The phrase “nucleic acid sequence” refers to a single or double-stranded polymer of deoxyribonucleotide or ribonucleotide bases read from the 5′ to the 3′ end. It includes chromosomal DNA, self-replicating plasmids, infectious polymers of DNA or RNA and DNA or RNA that performs a primarily structural role.
A “promoter” is defined as an array of nucleic acid control sequences that direct transcription of an operably linked nucleic acid. As used herein, a “plant promoter” is a promoter that functions in plants. Promoters include necessary nucleic acid sequences near the start site of transcription, such as, in the case of a polymerase II type promoter, a TATA element. A promoter also optionally includes distal enhancer or repressor elements, which can be located as much as several thousand base pairs from the start site of transcription. A “constitutive” promoter is a promoter that is active under most environmental and developmental conditions. An “inducible” promoter is a promoter that is active under environmental or developmental regulation. The term “operably linked” refers to a functional linkage between a nucleic acid expression control sequence (such as a promoter, or array of transcription factor binding sites) and a second nucleic acid sequence, wherein the expression control sequence directs transcription of the nucleic acid corresponding to the second sequence.
The term “plant” includes whole plants, plant organs (e.g., leaves, stems, flowers, roots, etc.), seeds and plant cells and progeny of same. The class of plants which can be used in the method of the invention is generally as broad as the class of flowering plants amenable to transformation techniques, including angiosperms (monocotyledonous and dicotyledonous plants), as well as gymnosperms. It includes plants of a variety of ploidy levels, including polyploid, diploid, haploid and hemizygous.
A polynucleotide sequence is “heterologous to” an organism or a second polynucleotide sequence if it originates from a foreign species, or, if from the same species, is modified from its original form. For example, a promoter operably linked to a heterologous coding sequence refers to a coding sequence from a species different from that from which the promoter was derived, or, if from the same species, a coding sequence which is different from any naturally occurring allelic variants.
A polynucleotide “exogenous to” an individual plant is a polynucleotide which is introduced into the plant, or a predecessor generation of the plant, by any means other than by a sexual cross. Examples of means by which this can be accomplished are described below, and include Agrobacterium-mediated transformation, biolistic methods, electroporation, in planta techniques, and the like. “Exogenous,” as referred to within, is any polynucleotide, polypeptide or protein sequence, whether chimeric or not, that is initially or subsequently introduced into the genome of an individual host cell or the organism regenerated from said host cell by any means other than by a sexual cross. Examples of means by which this can be accomplished are described below, and include Agrobacterium-mediated transformation (of dicots—e.g. Salomon et al. EMBO J. 3:141 (1984); Herrera-Estrella et al. EMBO J. 2:987 (1983); of monocots, representative papers are those by Escudero et al., Plant J. 10:355 (1996), Ishida et al., Nature Biotechnology 14:745 (1996), May et al., Bio/Technology 13:486 (1995)), biolistic methods (Armaleo et al., Current Genetics 17:97 1990)), electroporation, in planta techniques, and the like. Such a plant containing the exogenous nucleic acid is referred to here as a T0 for the primary transgenic plant and T1 for the first generation. The term “exogenous” as used herein is also intended to encompass inserting a naturally found element into a non-naturally found location.
The phrase “host cell” refers to a cell from any organism. Preferred host cells are derived from plants, bacteria, yeast, fungi, insects or other animals, including humans. Methods for introducing polynucleotide sequences into various types of host cells are well known in the art.
The “biological activity of a polypeptide” refers to any molecular activity or phenotype that is caused by the polypeptide. For example, the ability to transfer a phosphate to a substrate or the ability to bind a specific DNA sequence is a biological activity. One biological activity of DMT is glycosylase activity, i.e., cleavage of the nucleotide base from the nucleotide sugar). Another biological activity of DMT is to demethylate nucleotides (e.g., DMT has 5′-methylcytosine glycosylase activity). In addition, DMT has the ability to modulate endosperm production, as described herein, and to modulate flowering time in plants. For example, when DMT expression or DMT activity is increased in a plant, the flowering time of the plant is delayed. Moreover, expression of a DMT polypeptide in a plant tissue (e.g., a leaf) that does not typically express the MEDEA gene (Grossniklaus U, et al., Science 280(5362):446–50 (1998)) results in the expression of MEDEA.
Additional biological activities of DMT polypeptides include: nuclear localization (e.g., as localized by amino acids 43–78 of SEQ ID NO:2); the ability to modulate plant organ size and/or number; the ability to modulate meristem size and/or activity; and to perform DNA repair, including nucleotide methylation or demethylation and/or repair and/or removal of mis-matched nucleotides from DNA.
An “expression cassette” refers to a nucleic acid construct, which when introduced into a host cell, results in transcription and/or translation of an RNA or polypeptide, respectively. Antisense or sense constructs that are not or cannot be translated are expressly included by this definition.
A “DMT nucleic acid” or “DMT polynucleotide sequence” of the invention is a subsequence or full length polynucleotide sequence of a gene which encodes a polypeptide involved in control of reproductive development and which, when the maternal allele is mutated or when DMT activity is reduced or eliminated in a maternal tissue or plant, allows for increased production of the endosperm and/or abortion of the embryo. In addition, overexpression of DMT in plants results in delayed time to flowering. Moreover, DMT is necessary and sufficient for expression of MEDEA in a plant cell. An exemplary nucleic acid of the invention is the Arabidopsis DMT sequence (SEQ ID NO:1). Additional DMT nucleic acid sequences from a variety of plant species are also provided (e.g., SEQ ID NOs: 7–70). DMT polynucleotides are defined by their ability to hybridize under defined conditions to the exemplified nucleic acids or PCR products derived from them. A DMT polynucleotide is typically at least about 30–40 nucleotides to about 7000, usually less than about 10,000 nucleotides in length. More preferably, DMT polynucleotides contain a coding sequence of from about 100 to about 5500 nucleotides, often from about 500 to about 3600 nucleotides in length. A DMT polypeptide is typically at least 500 amino acids, typically at least 1000 amino acids, more typically at least 1500 amino acids. In some embodiments, a DMT polypeptide comprises fewer than 2000 amino acids, more typically fewer than 3000 amino acid and still more typically fewer than 5000 or 7500 amino acid in length.

DMT domain A corresponds to amino acid positions 697 through 796 of SEQ ID NO:2. DMT domain B corresponds to amino acid positions 1192 through 1404 of SEQ ID NO:2. DMT domain C corresponds to amino acid positions 1452 through 1722 of SEQ ID NO:2. The consensus sequence provides amino acid sequences by position using single letter amino acid abbreviations. Numbers in carrots (“<” or “>”) refer to amino acid positions where there is no consensus and which therefore, can be any amino acid. Amino acid abbreviations in parentheses indicate alternative amino acids at the same position. Capitalized letters refer to predominant consensus amino acids and lower case letters refer to amino acids that are commonly found in DMT sequences, but are not predominant. Thus, it is a simple matter to identify whether any particular nucleic acid sequence is a DMT nucleic acid and/or encodes a DMT polypeptide.
The structure of full-length DMT polypeptides comprises the following domains and regions. These regions are generally described with reference to SEQ ID NO:2. First, as described above, domain B DMT polypeptides can comprise a bipartite nuclear localization signal (e.g., amino acid positions 43–60 and 61–78 in SEQ ID NO:2) comprised of basic amino acids. Amino acids 36–91 are homologous to human G/T mismatch-specific thymine DNA glycosylase (Genbank accession number AAC50540. 1), which has 5-methylcytosine glycosylase activity (Zhu et al., Nuc. Acids Res. 28:4157–4165 (2000)). DMT polypeptides also contain a leucine zipper sequence (e.g., positions 1330–1351 of SEQ ID NO:2), that can be involved in protein-protein interactions as well as DNA binding. In addition, the amino portion of the DMT polypeptide (amino acids 43–78) is generally basic, similar to histone H1. Thus, without intending to limit the scope of the invention, it is believed this basic portion of DMT facilitates interactions with DNA and/or chromatic proteins.
In addition, amino acids 1–800 is related to the beta subunit of bacterial DNA-dependent RNA polymerases. Without intending to limit the scope of the invention, it is believed the RNA polymerase-like domain facilitates interaction of DMT with DNA.
Amino acids 1167–1368 is related to proteins in the HhH-GPD superfamily. Amino acids 1,271 to 1,304 correspond to the conserved HhH-GPD motif. The corresponding DMT sequence is DKAKDYLLSIRGLGLKSVECVRLLTLHNLAFPVD (SEQ ID NO:75). Secondary structure prediction (Jpred program) indicates that DMT has two alpha-helices (1,271–1,279 and 1,286 to 1,295) that correspond to the conserved alphaK and alphaL helices in the HhH-GPD motif of the crystallized hOGG1 DNA repair protein (Bruner et al Nature 403:859–866 (2000)). In between the two helices (1280 to 1285), is a hairpin with conserved glycines (G1282 and G1284). Amino acids 1286 to 1295 are related to the alphaL helix of hOGG1, which contacts the DNA backbone (Bruner et al Nature 403:859–866 (2000). Thus, without intending to limit the scope of the invention, it is believed this region of DMT contacts the DNA. The catalytic lysine (K1286) and aspartic acid (D1304) residues are conserved in the HhH-GPD motif of DMT. Without intending to limit the scope of the invention, by analogy to hOGG1, K1286 is predicted to displace the modified base and to promote conjugate elimination of the 3′-phosphodiester bond. Without intending to limit the scope of the invention, by analogy to hOGG1, D1304 is believed to assist the reaction by transferring protons to and from K1286.
DMT nucleic acids are a new class of plant regulatory genes that encode polypeptides with sequence identity to members of the endonuclease III genes found in a diverse collection of organisms. Endonuclease III is implicated in various DNA repair reactions. Thus proteins related to endonuclease III are likely to have a chromosomal function. DMT (SEQ ID NO:1) is most related to endonuclease III from Deinococcus radiodurans Genbank Accession No. AE002073 (see, e.g., White, O. et al. Science 286:1571–1577 (1999)). DMT polypeptides have glycosylase activity (i.e., the capability to cleave the base portion of a nucleotide from the sugar portion). More particularly, DMT polypeptides have demethylase activity, and in more preferred embodiments, have 5-methylcytosine glycosylase activity. Demethylation activity can be assayed in vivo by expressing a candidate polypeptide in the nucleus of a cell and then assaying for a change in methylation of the cell's DNA. See, e.g., Vong, et al., Science 260:1926–1928 (1993). Changes in chromosomal methylation can be measured by comparing the ability of methylation sensitive and insensitive endonucleases to cleave DNA from a cell expressing a polypeptide suspected of having demethylase or methylase activity. Alternatively, bisulfate sequencing can be used to identify which base pairs are methylated in a DNA sequence. For a discussion of both methods, see Soppe et al., Molec. Cell. 6:791–802 (2000). In vitro assays to measure demethylase activity using labeled substrates are also known to those of skill in the art. See, e.g., Vhu et al., Proc. Natl. Acad. Sci. USA 97:5135–5139 (2000).
In the case of both expression of transgenes and inhibition of endogenous genes (e.g., by antisense, or sense suppression) one of skill will recognize that the inserted polynucleotide sequence need not be identical, but may be only “substantially identical” to a sequence of the gene from which it was derived. As explained below, these substantially identical variants are specifically covered by the term DMT nucleic acid.
In the case where the inserted polynucleotide sequence is transcribed and translated to produce a functional polypeptide, one of skill will recognize that because of codon degeneracy a number of polynucleotide sequences will encode the same polypeptide. These variants are specifically covered by the terms “DMT nucleic acid”. In addition, the term specifically includes those sequences substantially identical (determined as described below) with a DMT polynucleotide sequence disclosed here and that encode polypeptides that are either mutants of wild type DMT polypeptides or retain the function of the DMT polypeptide (e.g., resulting from conservative substitutions of amino acids in the DMT polypeptide). In addition, variants can be those that encode dominant negative mutants as described below.
Two nucleic acid sequences or polypeptides are said to be “identical” if the sequence of nucleotides or amino acid residues, respectively, in the two sequences is the same when aligned for maximum correspondence as described below. The terms “identical” or percent “identity,” in the context of two or more nucleic acids or polypeptide sequences, refer to two or more sequences or subsequences that are the same or have a specified percentage of amino acid residues or nucleotides that are the same, when compared and aligned for maximum correspondence over a comparison window, as measured using one of the following sequence comparison algorithms or by manual alignment and visual inspection. When percentage of sequence identity is used in reference to proteins or peptides, it is recognized that residue positions that are not identical often differ by conservative amino acid substitutions, where amino acids residues are substituted for other amino acid residues with similar chemical properties (e.g., charge or hydrophobicity) and therefore do not change the functional properties of the molecule. Where sequences differ in conservative substitutions, the percent sequence identity may be adjusted upwards to correct for the conservative nature of the substitution. Means for making this adjustment are well known to those of skill in the art. Typically this involves scoring a conservative substitution as a partial rather than a full mismatch, thereby increasing the percentage sequence identity. Thus, for example, where an identical amino acid is given a score of 1 and a non-conservative substitution is given a score of zero, a conservative substitution is given a score between zero and 1. The scoring of conservative substitutions is calculated according to, e.g., the algorithm of Meyers & Miller, Computer Applic. Biol. Sci. 4:11–17 (1988) e.g., as implemented in the program PC/GENE (Intelligenetics, Mountain View, Calif. USA).
The phrase “substantially identical,” in the context of two nucleic acids or polypeptides, refers to a sequence or subsequence that has at least 40% sequence identity with a reference sequence. Alternatively, percent identity can be any integer from 40% to 100%. More preferred embodiments include at least: 40%, 45%, 50%, 55%, 60%, 65%, 70%, 75%, 80%, 85%, 90%, 95%, or 99% compared to a reference sequence using the programs described herein; preferably BLAST using standard parameters, as described below. This definition also refers to the complement of a test sequence, when the test sequence has substantial identity to a reference sequence.
For sequence comparison, typically one sequence acts as a reference sequence, to which test sequences are compared. When using a sequence comparison algorithm, test and reference sequences are entered into a computer, subsequence coordinates are designated, if necessary, and sequence algorithm program parameters are designated. Default program parameters can be used, or alternative parameters can be designated. The sequence comparison algorithm then calculates the percent sequence identities for the test sequences relative to the reference sequence, based on the program parameters.
A “comparison window”, as used herein, includes reference to a segment of any one of the number of contiguous positions selected from the group consisting of from 20 to 600, usually about 50 to about 200, more usually about 100 to about 150 in which a sequence may be compared to a reference sequence of the same number of contiguous positions after the two sequences are optimally aligned. Methods of alignment of sequences for comparison are well-known in the art. Optimal alignment of sequences for comparison can be conducted, e.g., by the local homology algorithm of Smith & Waterman, Adv. Appl. Math. 2:482 (1981), by the homology alignment algorithm of Needleman & Wunsch, J. Mol. Biol. 48:443 (1970), by the search for similarity method of Pearson & Lipman, Proc. Nat'l Acad. Sci. USA 85:2444 (1988), by computerized implementations of these algorithms (GAP, BESTFIT, FASTA, and TFASTA in the Wisconsin Genetics Software Package, Genetics Computer Group, 575 Science Dr., Madison, Wis.), or by manual alignment and visual inspection.
One example of a useful algorithm is PILEUP. PILEUP creates a multiple sequence alignment from a group of related sequences using progressive, pairwise alignments to show relationship and percent sequence identity. It also plots a tree or dendogram showing the clustering relationships used to create the alignment. PILEUP uses a simplification of the progressive alignment method of Feng & Doolittle, J. Mol. Evol. 35:351–360 (1987). The method used is similar to the method described by Higgins & Sharp, CABIOS 5:151–153 (1989). The program can align up to 300 sequences, each of a maximum length of 5,000 nucleotides or amino acids. The multiple alignment procedure begins with the pairwise alignment of the two most similar sequences, producing a cluster of two aligned sequences. This cluster is then aligned to the next most related sequence or cluster of aligned sequences. Two clusters of sequences are aligned by a simple extension of the pairwise alignment of two individual sequences. The final alignment is achieved by a series of progressive, pairwise alignments. The program is run by designating specific sequences and their amino acid or nucleotide coordinates for regions of sequence comparison and by designating the program parameters. For example, a reference sequence can be compared to other test sequences to determine the percent sequence identity relationship using the following parameters: default gap weight (3.00), default gap length weight (0.10), and weighted end gaps.
Another example of algorithm that is suitable for determining percent sequence identity and sequence similarity is the BLAST algorithm, which is described in Altschul et al., J. Mol. Biol. 215:403–410 (1990). Software for performing BLAST analyses is publicly available through the National Center for Biotechnology Information. This algorithm involves first identifying high scoring sequence pairs (HSPs) by identifying short words of length W in the query sequence, which either match or satisfy some positive-valued threshold score T when aligned with a word of the same length in a database sequence. T is referred to as the neighborhood word score threshold (Altschul et al, supra). These initial neighborhood word hits act as seeds for initiating searches to find longer HSPs containing them. The word hits are extended in both directions along each sequence for as far as the cumulative alignment score can be increased. Extension of the word hits in each direction are halted when: the cumulative alignment score falls off by the quantity X from its maximum achieved value; the cumulative score goes to zero or below, due to the accumulation of one or more negative-scoring residue alignments; or the end of either sequence is reached. The BLAST algorithm parameters W, T, and X determine the sensitivity and speed of the alignment. The BLAST program uses as defaults a wordlength (W) of 11, the BLOSUM62 scoring matrix (see Henikoff & Henikoff, Proc. Natl. Acad. Sci. USA 89:10915 (1989)) alignments (B) of 50, expectation (E) of 10, M=5, N=−4 comparison of both strands.
The BLAST algorithm also performs a statistical analysis of the similarity between two sequences (see, e.g., Karlin & Altschul, Proc. Nat'l. Acad. Sci. USA 90:5873–5787 (1993)). One measure of similarity provided by the BLAST algorithm is the smallest sum probability (P(N)), which provides an indication of the probability by which a match between two nucleotide or amino acid sequences would occur by chance. For example, a nucleic acid is considered similar to a reference sequence if the smallest sum probability in a comparison of the test nucleic acid to the reference nucleic acid is less than about 0.2, more preferably less than about 0.01, and most preferably less than about 0.001.
“Conservatively modified variants” applies to both amino acid and nucleic acid sequences. With respect to particular nucleic acid sequences, conservatively modified variants refers to those nucleic acids which encode identical or essentially identical amino acid sequences, or where the nucleic acid does not encode an amino acid sequence, to essentially identical sequences. Because of the degeneracy of the genetic code, a large number of functionally identical nucleic acids encode any given protein. For instance, the codons GCA, GCC, GCG and GCU all encode the amino acid alanine. Thus, at every position where an alanine is specified by a codon, the codon can be altered to any of the corresponding codons described without altering the encoded polypeptide. Such nucleic acid variations are “silent variations,” which are one species of conservatively modified variations. Every nucleic acid sequence herein which encodes a polypeptide also describes every possible silent variation of the nucleic acid. One of skill will recognize that each codon in a nucleic acid (except AUG, which is ordinarily the only codon for methionine) can be modified to yield a functionally identical molecule. Accordingly, each silent variation of a nucleic acid which encodes a polypeptide is implicit in each described sequence.
As to amino acid sequences, one of skill will recognize that individual substitutions, deletions or additions to a nucleic acid, peptide, polypeptide, or protein sequence which alters, adds or deletes a single amino acid or a small percentage of amino acids in the encoded sequence is a “conservatively modified variant” where the alteration results in the substitution of an amino acid with a chemically similar amino acid. Conservative substitution tables providing functionally similar amino acids are well known in the art.
The following six groups each contain amino acids that are conservative substitutions for one another:

    1) Alanine (A), Serine (S), Threonine (T);
    2) Aspartic acid (D), Glutamic acid (E);
    3) Asparagine (N), Glutamine (Q);
    4) Arginine (R), Lysine (K);
    5) Isoleucine (I), Leucine (L), Methionine (M), Valine (V); and
    6) Phenylalanine (F), Tyrosine (Y), Tryptophan (W).

(see, e.g., Creighton, Proteins (1984)).



An indication that two nucleic acid sequences or polypeptides are substantially identical is that the polypeptide encoded by the first nucleic acid is immunologically cross reactive with the antibodies raised against the polypeptide encoded by the second nucleic acid. Thus, a polypeptide is typically substantially identical to a second polypeptide, for example, where the two peptides differ only by conservative substitutions. Another indication that two nucleic acid sequences are substantially identical is that the two molecules or their complements hybridize to each other under stringent conditions, as described below.
The phrase “selectively (or specifically) hybridizes to” refers to the binding, duplexing, or hybridizing of a molecule only to a particular nucleotide sequence under stringent hybridization conditions when that sequence is present in a complex mixture (e.g., total cellular or library DNA or RNA).
The phrase “stringent hybridization conditions” refers to conditions under which a probe will hybridize to its target subsequence, typically in a complex mixture of nucleic acid, but to no other sequences. Stringent conditions are sequence-dependent and will be different in different circumstances. Longer sequences hybridize specifically at higher temperatures. An extensive guide to the hybridization of nucleic acids is found in Tijssen, Techniques in Biochemistry and Molecular Biology—Hybridization with Nucleic Probes, “Overview of principles of hybridization and the strategy of nucleic acid assays” (1993). Generally, highly stringent conditions are selected to be about 5–10° C. lower than the thermal melting point (Tm) for the specific sequence at a defined ionic strength pH. Low stringency conditions are generally selected to be about 15–30° C. below the Tm. The Tm is the temperature (under defined ionic strength, pH, and nucleic concentration) at which 50% of the probes complementary to the target hybridize to the target sequence at equilibrium (as the target sequences are present in excess, at Tm, 50% of the probes are occupied at equilibrium). Stringent conditions will be those in which the salt concentration is less than about 1.0 M sodium ion, typically about 0.01 to 1.0 M sodium ion concentration (or other salts) at pH 7.0 to 8.3 and the temperature is at least about 30° C. for short probes (e.g., 10 to 50 nucleotides) and at least about 55° C., sometimes 60° C., and sometimes 65° C. for long probes (e.g., greater than 50 nucleotides). Stringent conditions may also be achieved with the addition of destabilizing agents such as formamide. For selective or specific hybridization, a positive signal is at least two times background, preferably 10 time background hybridization.
Nucleic acids that do not hybridize to each other under stringent conditions are still substantially identical if the polypeptides which they encode are substantially identical. This occurs, for example, when a copy of a nucleic acid is created using the maximum codon degeneracy permitted by the genetic code. In such cased, the nucleic acids typically hybridize under moderately stringent hybridization conditions.
In the present invention, genomic DNA or cDNA comprising DMT nucleic acids of the invention can be identified in standard Southern blots under stringent conditions using the nucleic acid sequences disclosed here. For the purposes of this disclosure, suitable stringent conditions for such hybridizations are those which include a hybridization in a buffer of 40% formamide, 1 M NaCl, 1% SDS at 37° C., and at least one wash in 0.2× SSC at a temperature of at least about 50° C., usually about 55° C. to about 60° C. and sometimes 65° C., for 20 minutes, or equivalent conditions. A positive hybridization is at least twice background. Those of ordinary skill will readily recognize that alternative hybridization and wash conditions can be utilized to provide conditions of similar stringency.
A further indication that two polynucleotides are substantially identical is if the reference sequence, amplified by a pair of oligonucleotide primers, can then be used as a probe under stringent hybridization conditions to isolate the test sequence from a cDNA or genomic library, or to identify the test sequence in, e.g., a northern or Southern blot.


DETAILED DESCRIPTION
This invention provides molecular strategies for controlling plant development, including methylation of chromosomal DNA, endosperm development and flowering time.
Reproduction in flowering plants involves two fertilization events in the haploid female gametophyte. One sperm nucleus fertilizes the egg to form the embryo. A second sperm nucleus fertilizes the central cell to form the endosperm, a unique tissue that supports the growth of the embryo. Fertilization also activates maternal tissue differentiation, the ovule integuments form the seed coat and the ovary forms the fruit.
The present invention is based, at least in part, on the discovery of a set of female-gametophytic mutations and the subsequent cloning of the gene involved, termed DEMETER (DMT), formally known as ATROPOS (ATR). Two mutant alleles of DMT disclosed here were created using a T-DNA tag, thereby disrupting an exon of the gene. The dmt mutations affect endosperm production, allowing for increased endosperm development. Generally, the mutant dmt alleles are not transmitted by the female gametophyte. Inheritance of a mutant dmt allele by the female gametophyte usually results in embryo abortion and endosperm overproduction, even when the pollen bears the wild-type DMT allele.
In contrast, transmission of dmt mutant alleles through the male gametophyte (i.e., pollen) is ecotype-dependent in Arabidopsis. For instance, in some ecotypes (e.g., Columbia), transmission of dmt mutant alleles is less than 50%. However, in Landsberg erecta, transmission is almost normal.
DMT is a repressor of endosperm both before and after fertilization. DMT is both necessary and sufficient for MEDEA transcription. DMT is related to 5-methylcytosine glycosylases. DMT regulates transcription of specific target genes (i.e., MEA) by a demethylation mechanism. DMT is also required for maintaining the proper global pattern of methylation of chromosomal DNA in cells.
The isolated sequences prepared as described herein, can be used in a number of techniques, for example, to suppress or enhance endogenous DMT gene expression. Modulation of DMT gene expression or DMT activity in plants is particularly useful, for example, in producing embryo-less or embryo-reduced seed, seed with increased endosperm, as part of a system to generate seed, to modulate time to flowering, organ identity, size and/or number,meristem size or activity in plants, or to modulate methylation, and thus gene expression in plants. Another use is the expression of DMT polynucleotides in animal cells, for instance as a DNA repair enzyme useful in preventing the unnatural proliferation of cells (including cancer) due to chromosomal lesions. See, e.g., Bruner, et al, Nature 403:859 (2000).
As described in more detail below, reduction of expression of DMT in plants results in a number of diverse phenotypes. Without intending to limit the invention to particular embodiments, it is belived that some of the phenotypes that are generated in plants are epigenetic mutations, i.e., effects due to differences in the methylation state of the chromosome that result in altered gene expression. Thus, DMT provides a powerful tool to develop any number of plant lines with a variety of desired phenotypes.
Isolation of DMT Nucleic Acids
Generally, the nomenclature and the laboratory procedures in recombinant DNA technology described below 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, Cold Spring Harbor Laboratory, Cold Spring Harbor, N.Y. (1989).
The isolation of DMT nucleic acids may be accomplished by a number of techniques. For instance, oligonucleotide probes based on the sequences disclosed here can be used to identify the desired gene in a cDNA or genomic DNA library. To construct genomic libraries, large segments of genomic DNA are generated by random fragmentation, e.g. using restriction endonucleases, and are ligated with vector DNA to form concatemers that can be packaged into the appropriate vector. To prepare a cDNA library, mRNA is isolated from the desired organ, such as ovules, and a cDNA library which contains the DMT gene transcript is prepared from the mRNA. Alternatively, cDNA may be prepared from mRNA extracted from other tissues in which DMT genes or homologs are expressed.
The cDNA or genomic library can then be screened using a probe based upon the sequence of a cloned DMT gene disclosed here. Probes may be used to hybridize with genomic DNA or cDNA sequences to isolate homologous genes in the same or different plant species. Alternatively, antibodies raised against a DMT polypeptide can be used to screen an mRNA expression library.
Alternatively, the nucleic acids of interest can be amplified from nucleic acid samples using amplification techniques. For instance, polymerase chain reaction (PCR) technology can be used to amplify the sequences of the DMT genes directly from genomic DNA, from cDNA, from genomic libraries or cDNA libraries. PCR and other in vitro amplification methods may also be useful, for example, to clone nucleic acid sequences that code for proteins to be expressed, to make nucleic acids to use as probes for detecting the presence of the desired mRNA in samples, for nucleic acid sequencing, or for other purposes.

Appropriate primers and probes for identifying DMT sequences from plant tissues are generated from comparisons of the sequences provided here with other related genes. For instance, DMT can be compared to the other endonuclease III genes, such as Genbank Accession No. AE002073. Using these techniques, one of skill can identify conserved regions in the nucleic acids disclosed here to prepare the appropriate primer and probe sequences. Primers that specifically hybridize to conserved regions in DMT genes can be used to amplify sequences from widely divergent plant species. Appropriate primers for amplification of the genomic region or cDNA of DMT include the following primers (SEQ ID NOS:76–119):

The amplification conditions are typically as follows. Reaction components: 10 mM Tris-HCl, pH 8.3, 50 mM potassium chloride, 1.5 mM magnesium chloride, 0.001% gelatin, 200 μM dATP, 200 μM dCTP, 200 μM dGTP, 200 μM dTTP, 0.4 μM primers, and 100 units per ml Taq polymerase. Program: 96 C for 3 min., 30 cycles of 96 C for 45 sec., 50 C for 60 sec., 72 for 60 sec, followed by 72 C for 5 min.
Standard nucleic acid hybridization techniques using the conditions disclosed above can then be used to identify full-length cDNA or genomic clones.
Alternatively, a number of methods for designing modifications of polynucleotide sequences are known to those of skill in the art. For example, oligonucleotide directed mutagenesis can be used to introduce site-specific mutations in a nucleic acid sequence of interest. Examples of such techniques are found in the references above and, e.g., in Reidhaar-Olson et al. Science, 241:53–57 (1988) and Ausubel et al. Similarly, gene shuffling (Stemmer Proc. Natl. Acad. Sci. USA 91:10747–10751(1994); Ostermeier et al. Proc. Natl. Acad. Sci. USA, 96: 3562–67(1999))) can be used to introduce variation into one or more DMT sequences or subsequences. For example, orthologous (between species) or homologous (within a species) DMT nucleic acids can be interchanged, combined or shuffled to produce novel variations within the scope of the invention.
Additionally, error prone PCR can also be used to introduce variation into a nucleic acid sequence. See, Leung et al. (1989) Technique 1:11–15 and Caldwell et al. (1992) PCR Methods Applic. 2:28–33.
Control of DMT Activity or Gene Expression
Since DMT genes are involved in controlling seed, in particular endosperm, development, inhibition of endogenous DMT activity or gene expression is useful in a number of contexts. For instance, reduction of DMT activity can be used for production of seed with enhanced endosperm. By reducing and/or eliminating DMT activity, plants with seed containing increased endosperm can be produced.
Alternatively, substantial inhibition of DMT activity can be used for production of fruit with small and/or degraded seed (referred to here as “seedless fruit”) after fertilization. In many plants, particularly dicots, the endosperm is not persistent and eventually is degraded. Thus, in plants of the invention in which DMT activity is inhibited, embryo-less seed do not persist and seedless fruit are produced. For production of dicots with enhanced endosperm, the most beneficial effect may be to reduce, but not eliminate DMT activity. On the other hand, in monocots, which have persistent endosperm, it is advantageous to eliminate DMT activity.
Alternatively, plants of the invention can be used to prevent pre-harvest sprouting in seeds, especially those derived from cereals. In these plants, the endosperm persists and is the major component of the mature seed. Premature growth of embryos in stored grain causes release of degradative enzymes which digest starch and other components of the endosperm. Plants of the present invention are useful in addressing this problem because the seeds lack an embryo and thus will not germinate.
Moreover, as discussed herein, time to flowering and DNA methylation can also be modulate by modulating DMT activity in a cell. For example, DMT can be used to modulate the amnount of methylated DNA in a cell. Indeed, since expression of many genes is dependent on thier methylation state, modulation of DMT activity modulates gene expression in a cell. Examples of genes whose expression is modulated by DMT include MEDEA.
One of skill will recognize that a number of methods can be used to modulate DMT activity or gene expression. DMT activity can be modulated in the plant cell at the gene, transcriptional, posttranscriptional, translational, or posttranslational, levels. Techniques for modulating DMT activity at each of these levels are generally well known to one of skill and are discussed briefly below.
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 N-nitroso-N-ethylurea. Alternatively, ionizing radiation from sources such as, for example, X-rays or gamma rays can be used.
Alternatively, homologous recombination can be used to induce targeted gene disruptions by specifically deleting or altering the DMT gene in vivo (see, generally, Grewal and Klar, Genetics 146:1221–1238 (1997) and Xu et al., Genes Dev. 10:2411–2422 (1996). Homologous recombination has been demonstrated in plants (Puchta et al., Experimentia 50:227–284 (1994), Swoboda et al., EMBO J. 13:484–489 (1994); Offringa et al., Proc. Natl. Acad. Sci. USA 90:7346–7350 (1993); and Kempin et al. Nature 389:802–803 (1997)).
In applying homologous recombination technology to the genes of the invention, mutations in selected portions of a DMT gene sequences (including 5′ upstream, 3′ downstream, and intragenic regions) such as those disclosed here are made in vitro and then introduced into the desired plant using standard techniques. Since the efficiency of homologous recombination is known to be dependent on the vectors used, use of dicistronic gene targeting vectors as described by Mountford et al. Proc. Natl. Acad. Sci. USA 91;4303–4307 (1994); and Vaulont et al. Transgenic Res. 4:247–255 (1995) are conveneiently used to increase the efficiency of selecting for altered DMT gene expression in transgenic plants. The mutated gene will interact with the target wild-type gene in such a way that homologous recombination and targeted replacement of the wild-type gene will occur in transgenic plant cells, resulting in suppression of DMT activity.
Alternatively, oligonucleotides composed of a contiguous stretch of RNA and DNA residues in a duplex conformation with double hairpin caps on the ends can be used. The RNA/DNA sequence is designed to align with the sequence of the target DMT gene and to contain the desired nucleotide change. Introduction of the chimeric oligonucleotide on an extrachromosomal T-DNA plasmid results in efficient and specific DMT gene conversion directed by chimeric molecules in a small number of transformed plant cells. This method is described in Cole-Strasuu et al. Science 273:1386–1389(1996) and Yoon et al. Proc. Natl. Acad. Sci. USA 93:2071–2076 (1996).
Gene expression can be inactivated using recombinant DNA techniques by transforming plant cells with constructs comprising trasposons or T-DNA sequences. DMT mutants prepared by these methods are identified according to standard techniques. For instance, mutants can be detected by PCR or by detecting the presence or absence of DMT in mRNA, e.g., by Northern blots. Mutants can also be selected by assaying for development of endosperm in the absence of fertilization.
The isolated nucleic acid sequences prepared as described herein, can also be used in a number of techniques to control endogenous DMT gene expression at various levels. Subsequences from the sequences disclosed here can be used to control, transcription, RNA accumulation, translation, and the like.
A number of methods can be used to inhibit gene expression in plants. For instance, antisense technology can be conveniently used. To accomplish this, a nucleic acid segment from the desired gene 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 suppression can act at all levels of gene regulation including suppression of RNA translation (see, Bourque Plant Sci. (Limerick) 105:125–149 (1995); Pantopoulos In Progress in Nucleic Acid Research and Molecular Biology, Vol. 48. Cohn, W. E. and K. Moldave (Ed.). Academic Press, Inc.: San Diego, Calif., USA; London, England, UK. p. 181–238; Heiser et al. Plant Sci. (Shannon) 127:61–69 (1997)) and by preventing the accumulation of mRNA which encodes the protein of interest, (see, Baulcombe Plant Mol. Bio. 32:79–88 (1996); Prins and Goldbach Arch. Virol. 141:2259–2276 (1996); Metzlaff et al. Cell 88:845–854 (1997), Sheehy et al., Proc. Nat. Acad. Sci. USA, 85:8805–8809 (1988), and Hiatt et al., U.S. Pat. No. 4,801,340).
The nucleic acid segment to be introduced generally will be substanitally identical to at least a portion of the endogenous DMT gene or genes to be repressed. The sequence, however, need not be perfectly identical to inhibit expression. The 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 in full length relative to either the primary transcription product or fully processed mRNA. 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 exton pattern, and homology of non-coding segments may be 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 7000 nucleotides is especially preferred.
A number of gene regions can be targeted to suppress DMT gene expression. The targets can include, for instance, the coding regions, introns, sequences from exon/intron junctions, 5′ or 3′ untranslated regions, and the like. In some embodiments, the constructs can be designed to eliminate the ability of regulatory proteins to bind to DMT gene sequences that are required for its cell- and/or tissue-specific expression. Such transcriptional regulatory sequences can be located either 5′-, 3′-, or within the coding region of the gene and can be either promote (positive regulatory element) or repress (negative regulatory element) gene transcription. These sequences can be identified using standard deletion analysis, well known to those of skill in the art. Once the sequences are identified, an antisense construct targeting these sequences is introduced into plants to control gene transcription in particular tissue, for instance, in developing ovules and/or seed. In one embodiment, transgenic plants are selected for DMT activity that is reduced but not eliminated.
Oligonucleotide-based triple-helix formation can be used to disrupt DMT gene expression. Triple DNA can inhibit DNA transcription and replication, generate site-specific mutations, cleave DNA, and induce homologous recombination (see, e.g., Havre and Glazer J. Virology 67:7324–7331 (1993); Scanlon et al FASEB J. 9:1288–1296 (1995); Giovannangeli et al. Biochemistry 35:10539–10548 (1996); Chan and Glazer J. Mol. Medicine (Berlin) 75:267–282 (1997)). Triple heliz DNAs can be used to target the same sequences identified for antisense regulation.
Catalytic RNA molecules or ribozymes can also be used to inhibit expression of DMT genes. It is possible to design ribozymes that specifically pair with virtually any target RNA and cleave the phosphodiester backbone at a specific location, thereby functionally inactivating the target RNA. 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 RNAs confers RNA-cleaving activity upon them, thereby increasing the activity of the constructs. Thus, ribozymes can be used to target the same sequences identified for antisense regulation.
A number of classes of ribozymes have been identified. One class of ribozymes is derived from a number of small circular RNAs which are capable of self-cleavage and replication in plants. The RNAs replicate either alone (viroid RNAs) or with a helper virus (satellite RNAs). Examples include RNAs from avocado sunblotch viroid and the satellite RNAs 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 RNA-specific ribozymes is described in Zhao and Pick Nature 365:448–451 (1993); Eastham and Ahlering J. Urology 156:1186–1188 (1996); Sokol and Murray Transgenic Res. 5:363–371 (1996); Sun et al. Mol. Biotechnology 7:241–251 (1997); and Haseloff et al. Nature, 334:585–591 (1988).
Another method of suppression is sense cosuppression. Introduction of nucleic acid configured in the sense orientation has been recently shown to be an effective means by which to block the transcription of target genes. For an example of the use of this method to modulate expression of endogenous genes (see, Assaad et al. Plant Mol. Bio. 22:1067–1085 (1993); Flavell Proc. Natl. Acad. Sci. USA 91:3490–3496 (1994); Stam et al. Annals Bot. 79:3–12 (1997); Napoli et al., The Plant Cell 2:279–289 (1990); and U.S. Pat. Nos. 5,034,323, 5,231,020, and 5,283,184).
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 substanitally 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 that are overexpressers. 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. In addition, the same gene regions noted for antisense regulation can be targeted using cosuppression technologies.
In a preferred embodiment, expression of a nucleic acid of interest can be suppressed by the simultaneous expression of both sense and antisense constructs (Waterhouse et al., Proc. Natl. Acad. Sci. USA 95:13959–13964 (1998). See also Tabara et al. Science 282:430–431 (1998).
Alternatively, DMT activity may be modulated by eliminating the proteins that are required for DMT cell-specific gene expression. Thus, expression of regulatory proteins and/or the sequences that control DMT gene expression can be modulated using the methods described here.
Another method is use of engineered tRNA suppression of DMT mRNA translation. This method involves the use of suppressor tRNAs to transactivate target genes containing premature stop codons (see, Betzner et al. Plant J. 11:587–595 (1997); and Choisne et al. Plant J. 11:597–604 (1997). A plant line containing constitutively expressed DMT gene that contains an amber stop codon is first created. Multiple lines of plants, each containing tRNA suppressor gene constructs under the direction of cell-type specific promoters are also generated. The tRNA gene construct is then crossed into the DMT line to activate DMT activity in a targeted manner. These tRNA suppressor lines could also be used to target the expression of any type of gene to the same cell or tissue types.
DMT proteins may form homogeneous to heterologous complexes in vivo. Thus, production of dominant-negative forms of DMT polypeptides that are defective in their abilities to bind to other proteins in the complex is a convenient means to inhibit endogenous DMT activity. This approach involves transformation of plants with constructs encoding mutant DMT polypeptides that form defective complexes and thereby prevent the complex from forming properly. The mutant polypeptide may vary from the naturally occurring sequence at the primary structure level by amino acid substitutions, additions, deletions, and the like. These modifications can be used in a number of combinations to produce the final modified protein chain. Use of dominant negative mutants to inactivate target genes is described in Mizukami et al. Plant Cell 8:831–845 (1996).
Another strategy to affect the ability of a DMT protein to interact with itself or with other proteins involves the use of antibodies specific to DMT. In this method cell-specific expression of DMT-specific Abs is used inactivate functional domains through antibody:antigen recognition (see, Hupp et al. Cell 83:237–245 (1995)).
After plants with reduced DMT activity are identified, a recombinant construct capable of expressing low levels of DMT in embryos can be introduced using the methods discussed below. In this fashion, the level of DMT activity can be regulated to produce preferred plant phenotypes. For example, a relatively weak promoter such as the ubiquitin promoter (see, e.g., Garbarino et al. Plant Physiol. 109(4):1371–8 (1995); Christensen et al Transgenic Res. 5(3): 213–8 (1996); and Holtorf et al. Plant Mol. Biol. 29(4):637–46 (1995)) is useful to produce plants with reduced levels of DMT activity or expression. Such plants are useful for producing, for instance, plants that produce seed with enhanced endosperm.
Use of Nucleic Acids of the Invention to Enhance DMT Gene Expression
Isolated sequences prepared as described herein can also be introduced into a plant cell, thereby modulating expression of a particular DMT nucleic acid to enhance or increase endogenous gene expression. For instance, without being bound to any theory, in light of DMT's relation to Exonuclease III and DNA glycosylases, applicants believe that DMT binds DNA or chromatin and acts to modulated transcription by modulating the methylation state of DNA. Enhanced expression can therefore be used to control plant morphology by controlling expression of genes under DMT's control, such as MEDEA, in desired tissues or cells. Enhanced expression can also be used, for instance, to increase vegetative growth by preventing the plant from setting seed. Where overexpression of a gene is desired, the desired gene from a different species may be used to decrease potential sense suppression effects.
Moreover, as discussed herein, time to flowering and DNA methylation can also be modulated by modulating DMT activity in a cell. For example, increased expression of DMT in a plant results in delayed time to flowering. Similarly, DMT can be used to modulate the amount of methylated DNA in a cell. Indeed, since expression of many genes is dependent on their methylation state, modulation of DMT activity modulates gene expression in a cell. Examples of genes whose expression is modulated by DMT include MEDEA.
One of skill will recognize that the polypeptides encoded by the genes of the invention, like other proteins, have different domains that perform functions. Thus, the gene sequences need not be full length, so long as the desired functional domain of the protein is expressed.
Modified protein chains can also be readily designed utilizing various recombinant DNA techniques well known to those skilled in the art and described in detail, below. For example, the chains can vary from the naturally occurring sequences at the primary structure level by amino acid substitutions, additions, deletions, and the like. These modifications can be used in a number of combinations to produce the final modified protein chain.
Preparation of Recombinant Vectors
To use isolated sequences in the above techniques, recombinant DNA vectors suitable for transformation of plant cells are prepared. Techniques for transforming a wide variety of flowering plant species are well known and described in the technical and scientific literature. See, for example, Weising et al. Ann. Rev. Genet. 22:421–477 (1988). A DNA sequence coding for the desired polypeptide, for example a cDNA sequence encoding a full length protein, will preferably be combined with transcriptional and translational initiation regulatory sequences which will direct the transcription of the sequence from the gene in the intended tissues of the transformed plant.
For example, for overexpression, a plant promoter fragment may be employed which will direct expression of the gene in all tissues of regenerated plant. Such promoters are referred to herein as “constitutive” promoters and are active under most environmental conditions and states of development or cell differentiation. Examples of constitutive promoters include the cauliflower mosaic virus (CaMV) 35S transcription initiation region, the 1′- or 2′-promoter derived from T-DNA of Agrobacterium tumafaciens, and other transciption initiation regions from various plant genes known to those of skill. Such genes include for example, ACT11 from Arabidopsis (Huand et al. Plant Mol. Biol. 33:125–139 (1996)), Cat3 from Arabidopsis (GenBank No. U43147, Zhong et al., Mol. Gen. Genet. 251:196–203 (1996)), the gene encoding stearoyl-acyl carrier protein desaturase from Brassica napus (Genbank No. X74782, Solocombe et al. Plant Physiol. 104:1167–1176 (1994)), GPc1 from maize (GenBank No. X15596, Martinex et al. J. Mol. Biol 208:551–565 (1989)), and Gpc2 from maize (GenBank No. U45855, Manjunath et al., Plant Mol. Biol. 33:97–112 (1997)).
Alternatively, the plant promoter may direct expression of the DMT nucleic acid in a specific tissue or may be otherwise under more precise environmental or developmental control. Examples of environment conditions that may effect transcription by inducible promoters include anaerobic conditions, elevated temperature, or the presence of light. Such promoters are referred to here as “inducible” or “tissue-specific” promoters. One of skill 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.
Examples of promoters under development control include promoters that initiate transcription only (or primarily only) in certain tissues, such as fruit, seeds, or flowers. Promoters that direct expression of nucleic acids in ovules, flowers or seeds are particularly useful in the present invention. As used herein a seed-specific promoter is one which directs expression in seed tissues, such promoters may be, for example, ovule-specific (which includes promoters which direct expression in maternal tissues or the female gametophyte, such as egg cells or the central cell), embryo-specific, endosperm-specific, integument-specific, seed coat-specific, or some combination thereof. Examples include a promoter from the ovule-specific BEL1 gene described in Reiser et al. Cell 83:735–742 (1995) (GenBank No. U39944). Other suitable seed specific promoters are derived from the following genes: MAC1 from maize (Sheridan et al. Genetics 142:1009–1020 (1996), Cat3 from maize (GenBank No. L05934, Abler et al. Plant Mol. Biol. 22:10131–1038 (1993), the gene encoding oleosin 18 kD from maize (GenBank No. J05212, Lee et al. Plant Mol. Biol. 26:1981–1987 (1994)), vivparous-1 from Arabidopsis (Genbank No. U93215), the gene encoding oleosin from Arabidopsis (Genbank No. Z17657). Atmyc1 from Arabidopsis (Urao et al. Plant Mol. Biol. 32:571–576 (1996), the 2s seed storage protein gene family from Arabidopsis (Conceicao et al.

JBL 26:196–1301 (1987), the napin gene family from Brassica napus (Sjodahl et al. Planta 197:264–271 (1995), the gene encoding the 2S storage protein from Brassica napus (Dasgupta et al.

Mol Gen, Genet. 246:266–268 (1995)).
In addition, the promoter sequences from the DMT genes disclosed here can be used to drive expression of the DMT polynucleotides of the invention or heterologous sequences. The sequences of the promoters are identified below.
If proper polypeptide expression is desired, a polyadenylation region at the 3′-end of the coding region should be included. The polyadenylation region can be derived from the natural gene, from a variety of other plant genes, or from T-DNA.
The vector comprising the sequences (e.g., promoters or coding regions) from genes of the invention will typically comprise a marker gene which confers a selectable phenotype on plant cells. For example, the marker may encode biocide resistance, particularly antibiotic resistance, such as resistance to kanamycin, G418, bleomycin, hygromycin, or herbicide resistance, such as resistance to chlorosulfuron or Basta.
Promoter and Enhancer Nucleic Acids of the Invention
The present invention provides polynucleotides useful as promoters and enhancers. The invention also provides methods of targeting heterologous polypeptides to a female gametrophye of a plant, including, e.g., the polar nuclei, the eggs and synergids and central cells. Promoter polynucleotides of the invention include, for example, sequences and subsequences of the DMT 5′ flanking DNA (SEQ ID NO:3), the 5′ UTR region (SEQ ID NO:6) and the 3′ flanking region (SEQ ID NO:4). In some embodiments, the promoter sequences are operably linked to the 5′ end of the DMT coding region, which is in turn fused to a polynucleotide of interest, typically encoding a polypeptide. An exemplary promoter sequence includes the last 3424 nucleotides of SEQ ID NO:3 linked to the first 1478 nucleotides of SEQ ID NO:5. In some embodiments, a further 444 nucletoides (e.g., the first 444 nucleotides of the DMT coding region) are incorporated into the promoter. In some embodiments, the promoter sequences of the invention specifically direct expression of polynucleotides to the female gametophye and does not direct expression in tissues following fertilization.
Production of Transgenic Plants
DNA constructs of the invention may be introduced into the genome of the desired plant host by a variety of conventional techniques. For example, the DNA construct may be introduced directly into the genomic DNA of the plant cell using techniques such as electroporation and microinjection of plant cell protoplasts, or the DNA constructs can be introduced directly to plant tissue using methods, such as DNA particle bombardment.
Microinjection techniques are known in the art and well described in the scientific and patent literature. The introduction of DNA constructs using polyethylene glycol precipitation is described in Paskowski et al. Embo. J. 3:2717–2722 (1984). Electroporation techniques are described in Fromm et al. Proc. Natl. Acad. Sci. USA 82:5824 (1985). Ballistic information techniques are described in Klein et al. Nature 327:70–73 (1987).
Alternatively, the DNA constructs may be combined with suitable T-DNA flanking regions and introduced into a conventional Agrobacterium tumefaciens host vector. The virulence functions of the Agrobacterium tumefaciens host will direct the insertion of the construct and adjacent marker into the plant cell DNA when the cell is infected by the bacteria. Agrobacterium tumefacients-mediated transformation techniques, including disarming and use of binary vectors, are well described in the scientific literature. See, for example Horsch et al. Science 233:496–498 (1984), and Fraly et al. Proc. Natl. Acad. Sci. USA 80:4803 (1983).
Transformed plant cells which are derived by any of the above transformation techniques can be cultured to regenerate a whole plant which possesses the transformed genotype and thus the desired phenotype such as increased seed mass. 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. Plant regeneration from cultured protoplasts is described in Evans et al., Protoplasts Isolation and Culture, Handbook of Plant Cell Culture, pp. 124–176, MacMillilan Publsihing 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 regeneration techniques are described generally in Klee et al. Ann. Rev. of Plant Phys. 38:467–486 (1987).
The nucleic acids of the invention can be used to confer desired traits on essentially any plant. Thus, the invention has use over a broad range of plants, including species from the genera Anacardium, Arachis, Asparagus, Atropa, Avena, Brassica, Citrus, Citrullus, Capsicum, Carthamus, Cocos, Coffea, Cucumis, Cucurbita, Daucus, Elaeis, Fragaria, Glycine, Gossypium, Helianthus, Heterocallis, Hordeum, Hyoscyamus, Lactuca, Linum, Lolium, Lupinus, Lycopersicon, Malus, Manihot, Majorana, Medicago, Nicotiana, Olea, Oryza, Panieum, Pannesetum, Persea, Phaseolus, Pistachia, Pisum, Pyrus, Prunus, Raphanas, Ricinus, Secale,Senecio, Sinapis, Solanum, Sorghum, Theobromus, Trigonella, Triticum, Vicia, Vigna, and Zea. 
One of skill will recognize that after the expression cassette is stably incorporated in transgenic plants and confirmed to be operable, it can be introduced into other plants by sexual crossing. Any of a number of standard breeding technioques can be used, depending upon the species to be crossed.
Seed obtained from plants of the present invention can be analyzed according to well known procedures to identify plants with the desired trait. If antisense or other techniques are used to control DMT gene expression. Northern blot analysis can be used to screen for desired plants. In addition, the presence of fertilization independent reproductive development can be detected. Plants can be screened, for instance, for the ability to form embryo-less seed, form seed that abort after fertilization, or set fruit in the absence of fertilization. These procedures will depend, part on the particular plant species being used, but will be carried out according to methods well known to those of skill.
DMT Mutations, Fragments and Fusions
As discussed above, DMT polynucleotides and polypeptides are not limited to the sequences disclosed herein. Those of skill in the art that conservative amino acid substitutions, as well as amino acid additions or deletions may not result in any change in biological activity. Moreover, sequence variants with at least one modulated biological activity of DMT are also contemplated. For example, at least one DMT activity can be increased or decreased by introduction of single or multiple amino acid changes from the sequences disclosed herein. Those of skill in the art will recognize that conservative amino acid substitutions in important domains are typically useful in generating more active DMT polypeptides. Conversely, non-conservative substitutions of amino acid residues in functional domains, such as the HhH region of DMT (e.g., amino acids 1272–1304 of SEQ ID NO:2) are likely to disrupt at least one biological activity such as DNA binding. In some embodiments, the fragments of the invention consist of about 100, 200, 300 400, 500, 600, 700, 800, 900, or 1000 amino acids.
Alternatively, fragments of the sequences disclosed herein are contemplated. In some preferred embodiments, the polypeptide fragments have at least one biological activity of DMT. For example, amino acid sequences comprising DMT domain B represent polypeptide fragments with glycosylase or demthylase activity. In some embodiments, a fragment comprising amino acids 1167–1404, 1192–1404, 1192–1368 or 1167–1368 of SEQ ID NO:2 have glycosylase activity.
Mutations, fragments and fusions are also useful as dominant negative mutations. For instance, different regions of the DMT protein are responsible for different biological activities. Thus, mutation or deletion of one functional domain can eliminate one but not all activities. For example, mutation or deletion of the DNA binding domain may result in proteins that interact with proteins necessary for DMT function, effectively titrating out those proteins and preventing an active DMT protein from acting. Similarly, DMT fragments comprising the DNA binding portion of the protein with an inactive enzymatic domain or lacking an enzymatic domain are also useful as dominant negative mutants by competing with active DMT polypeptides for DNA binding sites. As described herein, domains of DMT that can be modulated include: the leucine zipper, nuclear localization sequence, HhH domain, the aspartic acid of the GPD domain, as well a DMT domains A, B or C. Without intending to limit the scope of the invention, based on the data provided herein, DMT has glycosylase and demethylase activity and is a DNA repair enzyme.
Targeting the Polypeptides of the Invention to Chromosomal Regions
Without intending to limit the scope of the invention, based on the data provided herein, it is believed that DMT has glycosylase and/or demthylase activity and is a DNA repair enzyme. DNA methylation plays an important role in the repression of gene transcription during animal development including embyrogenesis, myogeneis and blood cell development. Methylated DNA is recognized by MeCP2 which in turn represses gene transcription by recruiting the Sin3 repressor complex that contains catalytically active histone deacetylase (Jones et al. Nature Genetics 19(2):187–191 (1998)). Histone H3 and H4 deactylation contributes to the formation of transcriptionally inactive chromatin. Thus, DMT can be used for the purpose of modulating the activity of target genes through chromatin architecture in animal cells as well as plant cells. For example, in some embodiments, DMT is used to catalytically remove 5-MeC from target gene DNA in several ways: e.g., (1) by fusing DMT to a sequence specific DNA binding protein, or (2) by fusing DMT to a subunit of the target repressor complex such as MeCP2 or Sin3. When combined with cell, tissue, or developmentally specific promoters DMT can be used to modulate specific sets of target genes.
In addition, reactive oxygen species, partially species that are produced as intermediates of aerobic respiration, are powerful oxidizing agents that escape the mitochondria and attach vial cellular components. Ionizing radiation and other agents that generate free radicals also produce reactive oxygen species that can attack the genome and cause lesions that are thought to have a key role in in causing cancer and ageing. For example, 7,8-dihydro-8-oxoguanine (oxoG) is a very deleterious adduct generated by oxidation of the guanine base in DNA. The oxoG protein can pair with either cytosine or adenine during DNA replication. Thus, oxoG residues in DNA give rise to G/C to T/A transversion mutations. These transversions are common somatic mutations found in human cancers. HhH-GPD enzymes, such as those described herein, represent a defense against oxoG bycatalysing the expulsion of the oxoG. Thus, in some embodiments, enhanced DMT activity is a method to reduce the incidence of mutations in animal cells. Also, DMT can be used to catalytically remove oxoG from a target gene by fusing DMT to a sequence specific DNA binding protein. When combined with a cell, tissue, or developmentally specific promoters DMT can be used to modulate repair of target genes.
As described above, the polypeptides of the invention can be targeted to chromosomal regions of interest by linking the polypeptides of the invention, including fragments with demethylase activity, to a DNA-binding domain that binds a target sequence. For example, it is known that an enzyme that methylates DNA (Dam methylase) can be targeted to specific sites in the genome (B. V. Steensel and S. Henikoff, Nature Biotechnology 18:424–428 (2000)). Specifically, the methylase was tethered to the DNA-binding domain of GAL4. When recombinant GAL4-methylase protein was expressed in transgenic Drosophila, targeted methylation occurred in a region of a few kilobases surrounding the GAL4 DNA binding sequence. In a analogous fashion, DMT, or a portion of DMT that has biological activity (e.g., a potion containing the HhH-GpD motif amino acids such as 1167 to 1368 of SEQ ID NO:2), can be tethered (e.g., as a translational fusion or chemically linked) to proteins that interact as specific sites in the genome. As a result, specific targeted regions of the genome are hypomethylated by DMT. As discussed above, typically hypomethylation promotes transciption of genes (S. E. Jacobesen, Current Biology 9, 617 (1999). The invention provides compositions and methods for methylation of a desired are of the chromosome by targeting DMT to those regions. Thus, these embodiments provide additional ways to activate transcription of a desired gene in a targeted chromosomal region.
The following Examples are offered by way of illustration, not limitation.
EXAMPLE
Example 1
This example shows the characterization of dmt mutant plants and the isolation of DMT.
Arabisopsis plants were transformed by infiltrating them with Agrobacterium containing the SKI15 T-DNA vector (generaously provided by D. Weigel (Salk Institute, La Jolla, Calif.). T1 seeds were harvested. The SKI15 vector has the bialaphos resistance (BAR) gene that allowed us to directly select transgenic plants in soil after spraying with the commercially available herbicide, Basta. Siliques from approximately 5,000 Basta resistant plants were opened, and those displaying approximately 50% seed abortion were identified.
Two lines, B13 and B33, were identified for further characterization. Genetic analysis of the mutants revealed that the dmt mutants were female sterile. Male fertility, however, depended on the genetic background of the mutant alleles. For instance, in the Columbia background, transmission of the dmt mutation is less than 50%. However, in the Landsberg erecta background, transmission through the male was almost normal.
Molecular analysis confirmed that the two mutations were allelic. For example, both the B13 and B33 alleles carry the SKI15 T-DNA within a DMT exon, confirming that disruption of the DMT gene resulted in the observed B13 and B33 phenotypes.
5′- and 3′-RACE were used to delineate the 5′- and 3′-ends of the cDNA, respectively. 5′-RACE was carried out using reagents and protocols provided by 5′ RACE System for Rapid Amplification of cDNA Ends, Version 2.0, GIBCO BRL, LIFE TECHNOLOGIES, Grand Island, N.Y. and Marathon cDNA Amplification Kit, Clontech, Palo Alta, Calif. Final gene specific 5′-RACE primers were SKES-4 (GGGAACAAGTGCACCARCTCC; SEQ ID NO:97) and SKES3.5 (CGATGATAXTGTCTCTTCGAGC; SEQ ID NO:95)3′-RACE was carried out using reagents and protocols provided by Marathon cDNA Amplification Kit, Clontech, Palo Alto. Final gene-specific 3′ end was obtained from cDNA library screening.
The nucleotide sequence of the genomic copy of DMT was also determined (SEQ ID NO:1). The 5′-end of the DMT RNA is located at position 3,425 of SEQ ID NO:1. The position of the 3′-end of the DMT RNA is at position 12,504 of SEQ ID NO:1. The position of the ATG translation initiation codon is at position 4,903 of SEQ ID NO:1. The position of the TAA translation termination codon is at position 12,321 of SEQ ID NO:1.
A portion of the DMT polynucleotide sequence, including the first exon, is encompassed by the bacterial artificial chromosome (BAC) clone T9J15TRB. For example, sequences 3820–4299, 4319–4558, 4546–5025 and 9320–9777 of SEQ ID NO:1 were previously determined using the BAC clone as a template. Moreover, a separate independently sequenced region (Bork, C. et al Gene 28:147–153 (1998)) also overlaps the DMT sequence at positions 11,087 to 12,785 of SEQ ID NO:1.
The predicted DMT protein has 1,729 amino acids. This sequence was compared to known protein sequences using BLAST and revealed homology to several Endonuclease III proteins. The highest homology was to the Endonuclease III protein from Deinococcus radiodurans, Genbank Accession No. AE002073 (see, e.g., White, O. et al. Science 286:1571–1577 (1999)). Other DMT motifs include two consecutive nuclear localization signals at positions 43–60 and 61–78 and a leucine zipper at positions 1330–1351.
Example 2
This example provides further evidence that mutant phenotypes are caused by loss-of-function mutations.
A new allele, dmt-3, was obtained. The dmt-3 allele was caused by insertion of the simple pD991 T-DNA vector (M. R. Sussman, et al., Plant Physiol. 124:1465 (2000) into the 2nd exon of the DMT gene. In contrast, the previous two alleles, dmt-1 and dmt-2, caused by insertion of the activation T-DNA vector, SKI015 vector. The mutant phenotypes generated by all three dmt alleles are the same. Because pD991 does not have activation sequences, it suggests that all three mutant alleles are loss-of-function alleles. Consistent with the conclusion, seed abortion can be rescued with a transgene with 3,373 base pairs of 5′-DMT flanking sequences plus 1,478 base pairs of 5′-UTR ligated to a cDNA encoding the full-length DMT polypeptide (i.e., DMTp::DMT). Thus, dmt/DMT heterozygous plants that are hemizygous for the DMTp::DMT transgene displayed 25% seed abortion. Control dmt/DMT plants displayed 50% seed abortion.
Example 3
This example shows that DMT is necessary and sufficient for MEA gene expression.
As discussed above, when fertilization of dmt/dmt homozygous mutant flowers was prevented, fertilization-independent endosperm development was observed. This is very similar to when fertilization of mutant mea flowers is prevented. Thus, before fertilization, both DMT and mEA, a polycomb protein (T. Kiyosue et al., Proc. Natl. Acad. USA 96:4186 (1999)), prevent the central cell of the female gametophyte from forming an endosperm. This is consistent with DMT being a positive regulator of MEDEA (MEA).
As further evidence of this relationship, MEA RNA accumulates in immature floral (IF) buds and open flowers (OF). However, in dmt/dmt mutant plants there was no detectable MEA RNA. Thus, DMT is necessary for MEA gene expression.
In addition, we have generated plants with a transgene, CaMV::DMT, designed to overexpress DMT. The full-length DMT cDNA was ligated to the constitutive cauliflower mosaic virus promoter, CaMV (S. G. Rogers, H. J. Klee, R. B. Horsch, R. T. Fraley, Meth Enzymol 153:253 (1987)). In control wild type plants, the DMT and MEA genes were not significantly expressed in the leaf. However, in 35S::DMT plants, both DMT and MEA RNA level increased significantly. This shows that DMT is sufficient to induce MEA gene expression in the leaf.
Example 4
This example shows that DMT is a member of the HhH-GPD superfamily of DNA repair enzymes.
A BLAST search, followed by a conserved domain search, revealed that DMT is highly related to the HhH-GPD superfamily of base excision DNA repair proteins (i.e., score of 70.1, E-value of 8e−13). This family contains a diverse range of structurally related DNA repair proteins. The superfamily is called the HhH-GPD family after its hallmark helix-hairpin-helix and Gly/Pro rich loop followed by a conserved apsartate (S. D. Bruner, et al., Nature 403:859 (2000)). Thi includes endonuclease III (EC:4.9.99.18), 8-oxoguanine DNA glycosylases (i.e., yeast OGG1), the thymine DNA glycosylase of methyl-CPG binding protein MBD4 (B. Hendrich, et al. Nature 401:301 (1999)), and DNA-3-methyladenine glycosylase II (EC:3.2.2.21). The predicted amino acid sequence of DMT contains many of the conserved amino acids of this superfamily.
The hallmark of the superfamily of base-excision DNA repair proteins is a helix-hairpin-helix structural element followed by a Gly/Pro-rich loop and a conserved aspartic acid (i.e., HhH-GPD motif). The DMT polypeptide is 1,729 amino acids in length. Amino acids 1,271 to 1,304 correspond to the conserved HhH-GPD motif. The DMT sequence is DKAKDYLLSIRGLGLKSVECVRLLTLHNLAFPVD (SEQ ID NO:75). The catalytic lysin (K1286) and asparatic acid (D1304) residues are conserved in the HhH-GPD motif of DMT. Secondary structure prediction (Jpred program) indicates that DMT has two alpha-helices (amino acids 1,271–1,279 and 1,286 to 1,295) that correspond to the conserved alphaK and alphaL helices in the HhH-GPD motif of the crystallized hOGG1 DNA repair protein (Bruner et al Nature 403:859–866 (2000)).
The Arabidopsis DMT coding sequence were also used to identify homologous sequences in both public and proprietary databases using both the BLAST and PSI-BLAST computer algorithms. This analysis revealed amino acid sequences from several plant species, including wheat, maize, rice, soybean and Arabidopsis (SEQ ID NOS:8,9,11,12,14,15,17,18,20,22,24,25,27, and 29) (SEQ ID NOs:7–29). Based on these sequences, the following consensus sequences for DMT were determined:

The first consensus sequence listed above corresponds to amino acid positions 586 throuh 937 of SEQ ID NO:2.

The consensus sequence provides amino acid sequences by position using single letter amino acid abbreviations.

Example 5
This example demonstrates the relationship between DNA repair and demethylation.
For many years, attention was focused on the ability of DNA glycosylases to repair DNA. For example, glycosylases are involved in the repair of G/T mismatched bases by depurinating the thymidine base moiety. Recently it was shown that avian (B. Zhu et al., Proc. Natl. Acad. Sci. USA 97:5135 (2000)) and mammalian (B. Zhu et al., Nucl. Acid Res. 28:4157 (2000)). G/T mismatch DNA glycosylases also have 5-methylcytosine-DNA glycosulase activity. That is, these enzymes are demthylases that remove 5-methylcytosine that is later replaced by cytosine. Without intending to limit the scope of the invention, it is believed that as a member of this superfamily, DMT is a demthylase (i.e., 5-methylcytosine glycosylase).
The methylation (i.e., amount of 5-methylcytosine) state of a gene can have a profound effect on its expression. In general, hypomethylation is associated with elevated gene expression, whereas hypermethylation is associated with decreased gene expression (S. E. Jacobsen, Current Biology 9:617 (1999)). Thus, it is likely that DMT activates MEA gene expression by reducing its level of methylation.
Mutations in the DDM1 gene in Arabidopsis reduce by 70% the overall genome cytosine methylation (E. J. Finnegan, et al., Proc. Natl. Acad. Sci. USA 93:8449 (1996); M. J. Ronemus, et al., Science 273:654 (1996)). Such plants develop a number of phenotypuc abnormalities including floral phenotypes (T. Kakutani, et al., Proc. Natl. Acad. Sci. USA 93:12406 (1996)). Similarly, phenotypic abnormalities have been observed developing in dmt/dmt homozygous plants that affect petal number, floral organ fusion, and floral organ identity. Moreover, independent CaMV::DMT transgenic lines that overexpress DMT frequently are late-flowering. This is particularly interesting because late flowering of ddm1 plants was shown to be due to hypomethylation of the FWA gene (W. J. J. Soppe et al., Mol Cell 6:791 (2000)). Thus, without intending to limit the scope of the invention, it is believed that both ddm1 loss-of-function mutations and overexpression of DMT (i.e., CaMV::DMT) may result in genome hypomethylation.
Example 6
This example demonstrates targeting gene expression to the female gametophyte using a DMT promoter sequence.
DMT RNA accumulates in many plant organs such as immature flowers, mature flowers, open flowers, stems and to a lesser extent, leaves. To understand the spatial and temporal regulation of DMT RNA accumulation, the expression of the DMT promoter fused to reporter genes was analyzed. We fused 2,282 base pairs of 5′-DMT sequences, the full-length 5′-UTR (1,478 base pairs), 444 base pairs of DMT coding sequences that contain a nuclear localization signal to two reported genes, the green fluorescent protein (GFP; (Y. Niwa, et al., Plant J. 18:455 (199))) and β-glucuronidase (GUS;; (R. A. Jefferson, T. A. Kavanaugh, M. V. Bevan, EMBO J. 6:3901 (1987))). Reported gene expression was observed in the developing female gametophyte, in the polar nuclei before they fuse, in the egg and synergids, and in the central cell. Expression was not detected after fertilization. Thus, this promoter is useful for targeting gene expression to the female gametophyte.

## Claims

1. A method of modulating development in a plant, the method comprising:
introducing into a plant an expression, cassette comprising a promoter operably linked to an expression-inhibiting polynucleotide, wherein the expression-inhibiting polynucleotide comprises SEO ID NO:1 or SEO ID NO:5, thereby producing a plant that exhibits:
(a) modulated floral organ identity;
(b) modulated floral organ number;
(c) increased meristem size; or
(d) increased endosperm size.

2. The method of claim 1, wherein the promoter is a constitutive promoter.

3. The method of claim 1, wherein the promoter is a tissue-specific promoter.

4. A method of delaying flowering in a plant, the method comprising:
introducing into a plant an expression cassette comprising a promoter operably linked to a DMT polynucleotide encoding a polypeptide comprising SEQ ID NO:2, thereby delaying flowering of the plant compared to a plant lacking the expression cassette.

5. The method of claim 4, wherein the polynucleotide comprises SEQ ID NO:5.

6. The method of claim 4, wherein the polynucleotide comprises SEQ ID NO:1.

7. The method of claim 4, wherein the promoter is a constitutive promoter.

8. The method of claim 4, wherein the promoter is a tissue-specific promoter.
