Description: Nucleic acid sequences and methods for the modification of plant gene expression Technical Field of the Invention This invention relates to the regulation of polynucleotide transcription and/or expression. More specifically, this invention relates to polynucleotide regulatory sequences isolated from plants that are capable of initiating and driving the transcription of polynucleotides, and the use of such regulatory sequences in the modification of transcription of endogenous and/or heterologous polynucleotides and production of polypeptides. Polypeptide sequences are also disclosed. Background of the Invention Gene expression is regulated, in part, by the cellular processes involved in transcription. During transcription, a single-stranded RNA complementary to the DNA sequence to be transcribed is formed by the action of RNA polymerases. Initiation of transcription in eukaryotic cells is regulated by complex interactions between cw-acting DNA motifs, located within the gene to be transcribed, and trans-acting protein factors. Among the cώ-acting regulatory regions are sequences of DNA, termed promoters, to which RNA polymerase is first bound, either directly or indirectly. As used herein, the term "promoter" refers to the 5' untranslated region of a gene that is associated with transcription and which generally includes a transcription start site. Other cis-acting DNA motifs, such as enhancers, may be situated further up- and/or down-stream from the initiation site. Both promoters and enhancers are generally composed of several discrete, often redundant elements, each of which may be recognized by one or more trans-acting regulatory proteins, known as transcription factors. Promoters generally comprise both proximal and more distant elements. For example, the so-called TATA box, which is important for the binding of regulatory proteins, is generally found about 25 basepairs upstream from the initiation site. The so-called CAAT box is generally found about 75 basepairs upstream of the initiation site. Promoters generally contain between about 100 and 1000 nucleotides, although longer promoter sequences are possible. For the development of transgenic plants, constitutive promoters that drive strong transgene expression are preferred. Currently, the only available constitutive plant promoter that is widely used is derived from Cauliflower Mosaic Virus. Furthermore, there exists a need for plant-derived promoters for use in transgenic food plants due to public conceptions regarding the use of viral promoters. Few gymnosperm promoters have been cloned and those derived from angiosperms have been found to function poorly in gyrnnosperms. There thus remains a need in the art for polynucleotide promoter regions isolated from plants for use in modulating transcription and expression of polynucleotides in transgenic plants. Summary of the Invention Briefly, isolated polynucleotide regulatory sequences from eucalyptus and pine that are involved in the regulation of gene expression are disclosed, together with methods for the use of such polynucleotide regulatory regions in the modification of expression of endogenous and/or heterologous polynucleotides in transgenic plants. In particular, the present invention provides polynucleotide promoter sequences from 5' untranslated, or non- coding, regions of plant genes that initiate and regulate transcription of polynucleotides placed under their control, together with isolated polynucleotides comprising such promoter sequences. In a first aspect, the present invention provides isolated polynucleotide sequences comprising a polynucleotide selected from the group consisting of: (a) sequences recited in SEQ ID NO: 1-14, 20, 22-62, 81-86 and 88-127; (b) complements of the sequences recited in SEQ ID NO:- 1-14., 20, 22-62, 81-86 and 88-127; (c) reverse complements of the sequences recited in SEQ ID NO: 1-14, 20, 22-62, 81-86 and 88-127; (d) reverse sequences of the sequences recited in SEQ TD NO: 1-14, 20, 22-62, 81-86 and 88-127; (e) sequences having either 40%, 60%, 75% or 90% identical nucleotides. as defined herein, to a sequence of (a) - (d); probes and primers corresponding to the sequences set out in SEQ ID NO: 1-14, 20, 22- 62, 81-86 and 88-127; polynucleotides comprising at least a specified number of contiguous residues of any of the polynucleotides identified as SEQ ID NO: 1-14, 20, 22-62, 81-86 and 88-127; and extended sequences comprising portions of the sequences set out in SEQ ID NO: 1-14, 20, 22-62, 81-86 and 88-127; all of which are referred to herein as "polynucleotides of the present invention." The present invention also provides isolated polypeptide sequences identified in the attached Sequence Listing as SEQ ID NO: 63-80, 87 and 130; polypeptide variants of those sequences; and polypeptides comprising the isolated polypeptide sequences and variants of those sequences. In another aspect, the present invention provides genetic constructs comprising, a polynucleotide of the present invention, either alone, or in combination with one or more additional polynucleotides of the present invention, or in combination with one or more known polynucleotides, together with cells and target organisms comprising such constructs. In a related aspect, the present invention provides genetic constructs comprising, in the 5 '-3' direction, a polynucleotide promoter sequence of the present invention, a polynucleotide 'to be transcribed, and a gene termination sequence. The polynucleotide to be transcribed may comprise an open reading frame of a polynucleotide that encodes a polypeptide of interest, or it may be a non-coding, or untranslated, region of a polynucleotide of interest. The open reading frame may be orientated in either a sense or antisense direction. Preferably, the gene termination sequence is functional in a host plant. Most preferably, the gene termination sequence is that of the gene of interest, but others generally used in the art, such as the Agrobacterium tumefaciens nopalin synthase terminator may be usefully employed in the present invention. The genetic construct may further include a marker for the identification of transformed cells. In a further aspect, transgenic plant cells comprising the genetic constructs of the present invention are provided, together with organisms, such as plants, comprising such transgenic cells, and fruits, seeds and other products, derivatives, or progeny of such plants. Propagules of the inventive transgenic plants are included in the present invention. As used herein, the word "propagule" means any part of a plant that may be used in reproduction or propagation, sexual or asexual, including cuttings. Plant varieties, particularly registerable plant varieties according to Plant Breeders' Rights, may be excluded from the present invention. A plant need not be considered a "plant variety" simply because it contains stably within its genome a transgene, introduced into a cell of the plant or an ancestor thereof. In yet another aspect, methods for modifying gene expression in a target organism, such as a plant, are provided, such methods including stably incorporating into the genome of the organism a genetic construct of the present invention. In a preferred embodiment, the target organism is a plant, more preferably a woody plant, most preferably selected from the group consisting of eucalyptus and pine species, most preferably from the group consisting of Eucalyptus grandis and Pinus radiata. In another aspect, methods for producing a target organism, such as a plant, having modified polypeptide expression are provided, such methods comprising transforming a plant cell with a genetic construct of the present invention to provide a transgenic cell, and cultivating the transgenic cell under conditions conducive to regeneration and mature plant growth. In other aspects, methods for identifying a gene responsible for a desired function or phenotype are provided, the methods comprising transforming a plant cell with a genetic construct comprising a polynucleotide promoter sequence of the present invention operably linked to a polynucleotide to be tested, cultivating the plant cell under conditions conducive to regeneration and mature plant growth to provide a transgenic plant; and comparing the phenotype of the transgenic plant with the phenotype of non-transformed, or wild-type, plants. In yet a further aspect, the present invention provides isolated polynucleotides that encode ubiquitin. In specific embodiments, the isolated polynucleotides comprise a polynucleotide selected from the group consisting of: (a) sequences recited in SEQ ID NO: 1 and 34; (b) complements of the sequences recited in SEQ ID NO: 1 and 34; (c) reverse complements of the sequences recited in SEQ ID NO: 1 and 34; (d) reverse sequences of the sequence recited in SEQ ID NO: 1 and 34; and (e) sequences having either 40%, 60%, 75% or 90% identical nucleotides, as defined herein, to a sequence of (a) - (d). Polypeptides encoded by such polynucleotides are also provided, together with genetic constructs comprising such polynucleotides, and host cells and transgenic organisms, for example plants, transformed with such genetic constructs. In specific embodiments, such polypeptides comprise a sequence provided in SEQ ID NO: 80 or 67. In yet further aspects, the present invention provides isolated polynucleotides comprising the DNA sequence of SEQ ID NO: 21, or a complement, reverse complement or variant of SEQ ID NO: 21, together with genetic constructs comprising such polynucleotides and cells transformed with such sequences. As discussed below, removal of the sequence of SEQ ID NO: 21 from a polynucleotide that comprises the sequence of SEQ ID NO: 21 may enhance expression of the polynucleotide. Conversely, the inclusion of the sequence of SEQ ID NO: 21 in a genetic construct comprising a polynucleotide of interest may decrease expression of the polynucleotide. The above-mentioned and additional features of the present invention and the manner of obtaining them will become apparent, and the invention will be best understood by reference to the following more detailed description. All references disclosed herein are hereby incorporated by reference in their entirety as if each was incorporated individually. Brief Description of the Drawings Fig. 1 shows the expression in A. thaliana of the GUS gene in promoter reporter constructs containing either the superubiquitin promoter with introns, the superubiquitin promoter without introns, or the CaMV 35S promoter. The GUS expression was measured by fluorimetric determination of 4-methyl-umbelliferone (MTJ) in protein extracts from these plants. Fig. 2 shows the expression of the GUS gene in tobacco plant protoplasts by. deletion constructs containing the superubiquitin promoter with or without the intron. The constructs contained 1,103; 753; 573; 446; 368; and 195 bp upstream of the TATA sequence (bp numbers 1,104-1,110 of SEQ ID NO: 2). The GUS expression was measured by fluorimetric determination of 4-methyl-umbelliferone (MU) in protein extracts from these protoplasts.

Fig. 5 shows the expression in A. thaliana of the GUS gene in promoter reporter constructs containing the 3' UTR of the superubiquitin promoter in sense or antisense orientation together with either the superubiquitin promoter with intron, the superubiquitin promoter without intron, or the CaMV 35S promoter. The GUS expression was measured by fluorimetric determination of 4-methyl-umbelliferone (MU) in protein extracts from these plants. Detailed Description of the Invention The present invention provides isolated polynucleotide regulatory regions that may be employed in the manipulation of plant phenotypes, together with isolated polynucleotides comprising such regulatory regions. More specifically, polynucleotide promoter sequences isolated from pine and eucalyptus are disclosed. As discussed above, promoters are components of the cellular "transcription apparatus" and are involved in the regulation of gene expression. Both tissue- and temporal-specific gene expression patterns have been shown to be initiated and controlled by promoters during the natural development of a plant. The isolated polynucleotide promoter sequences of the present invention may thus be employed in the modification of growth and development of plants, and of cellular responses to external stimuli, such as environmental factors and disease pathogens. Using the methods and materials of the present invention, the amount of a specific polypeptide of interest may be increased or reduced by incorporating additional copies of genes, or coding sequences, encoding the polypeptide, operably linked to an inventive promoter sequence, into the genome of a target organism, such as a plant. Similarly, an increase or decrease in the amount of the polypeptide may be obtained by transforming the target plant with antisense copies of such genes. The polynucleotides of the present invention were isolated from forestry plant sources, namely from Eucalyptus grandis and Pinus radiata, but they may alternatively be synthesized using conventional synthesis techniques. Specifically, isolated polynucleotides of the present invention include polynucleotides comprising a sequence selected from the group consisting of sequences identified as SEQ ID NO: 1-14, 20, 22-62, 81-86 and 88-127; complements of the sequences identified as SEQ ID NO: 1-14, 20, 22-62, 81-86 and 88-127; reverse complements of the sequences identified as SEQ ID NO: 1-14, 20, 22-62, 81-86 and 88-127; at least a specified number of contiguous residues (x-mers) of any of the above- mentioned polynucleotides; extended sequences corresponding to any of the above polynucleotides; antisense sequences corresponding to any of the above polynucleotides; and variants of any of the above polynucleotides, as that term is described in this specification. In another embodiment, the present invention provides isolated polypeptides encoded by the polynucleotides of SEQ ID NO: 63-80, 87 and 130. The polynucleotides and polypeptides of the present invention were putatively identified by DNA and polypeptide similarity searches. In the attached Sequence Listing, SEQ ID NOS. 1-14, 20, 22-62, 81-86 and 88-127 are polynucleotide sequences, and SEQ ID NOS. 63-80, 87 and 130 are polypeptide sequences. The polynucleotides and polypeptides of the present invention have demonstrated similarity to promoters that are known to be involved in regulation of transcription and/or expression in plants. The putative identity of each of the inventive polynucleotides is shown below in Table 1, together with the 5' untranslated region (5' UTR) or putative promoter region (identified by residue number). TABLE 1 In one embodiment, the present invention provides polynucleotide sequences isolated from Pinus radiata and Eucalyptus grandis that encode a ubiquitin polypeptide. The mil- length sequence of the ubiquitin polynucleotide isolated from Pinus radiata is provided in SEQ ID NO: 1, with the sequence of the promoter region including an intron being provided in SEQ ID NO: 2 and the sequence of the promoter region excluding the intron being provided in SEQ ID NO: 3. The sequence of the ubiquitin polynucleotide isolated from Eucalyptus grandis is provided in SEQ ID NO: 34. In a related embodiment, the present invention provides isolated polypeptides encoded by the isolated polynucleotides of SEQ ID NO: 1 and 34, including polypeptides comprising the sequences of SEQ ID NO: 80 and 67. The term "polynucleotide(s)," as used herein, means a single or double-stranded polymer of deoxyribonucleotide or ribonucleotide bases and includes DNA and corresponding RNA molecules, including HnRNA and mRNA molecules, both sense and anti-sense strands, and comprehends cDNA, genomic DNA and recombinant DNA, as well as wholly or partially synthesized polynucleotides. An HnRNA molecule contains introns and corresponds to a DNA molecule in a generally one-to-one manner. An mRNA molecule corresponds to an HnRNA and DNA molecule from which the introns have been excised. A polynucleotide may consist of an entire gene, or any portion thereof. Operable anti-sense polynucleotides may comprise a fragment of the corresponding polynucleotide, and the definition of "polynucleotide" therefore includes all such operable anti-sense fragments. Anti-sense polynucleotides and techniques involving anti-sense polynucleotides are well known in the art and are described, for example, in Robinson-Benion et al. "Antisense techniques," Methods in Enzymol. 254(23):363-375, 1995; and Kawasaki et al., in Artific. Organs 20(8):836-848, 1996. All of the polynucleotides and polypeptides described herein are isolated and purified, as those teπns are commonly used in the art. Preferably, the polypeptides and polynucleotides are at least about 80% pure, more preferably at least about 90% pure, and most preferably at least about 99% pure. The definition of the terms "complement", "reverse complement" and "reverse sequence", as used herein, is best illustrated by the following example. For the sequence 5' AGGACC 3', the complement, reverse complement and reverse sequence are as follows: Complement 3 ' TCCTGG 5 ' Reverse complement 3' GGTCCT 5' Reverse sequence 5' CCAGGA 3' Some of the polynucleotides of the present invention are "partial" sequences, in that they do not represent a full-length gene encoding a full-length polypeptide. Such partial sequences may be extended by analyzing and sequencing various DNA libraries using primers and/or probes and well known hybridization and/or PCR techniques. Partial sequences may be extended until an open reading frame encoding a polypeptide, a full-length polynucleotide and/or gene capable of expressing a polypeptide, or another useful portion of the genome is identified. Such extended sequences, including full-length polynucleotides and genes, are described as "corresponding to" a sequence identified as one of the sequences of SEQ ID NO: 1-14, 20, 22-62, 81-86 and 88-127, or a variant thereof, or a portion of one of the sequences of SEQ ID NO: 1-14, 20, 22-62, 81-86 and 88-127, or a variant thereof, when the extended polynucleotide comprises an identified sequence or its variant, or an identified contiguous portion (x-mer) of one of the sequences of SEQ ID NO: 1-14, 20, 22-62, 81-86 and 88-127, or a variant thereof. Such extended polynucleotides may have a length of from about 50 to about 4,000 nucleic acids or base pairs, and preferably have a length of less than about 4,000 nucleic acids or base pairs, more preferably yet a length of less than about 3,000 nucleic acids or base pairs, more preferably yet a length of less than about 2,000 nucleic acids or base pairs. Under some circumstances, extended polynucleotides of the present invention may have a length of less than about 1,800 nucleic acids or base pairs, preferably less than about 1,600 nucleic acids or base pairs, more preferably less than about 1,400 nucleic acids or base pairs, more preferably yet less than about 1,200 nucleic acids or base pairs, and most preferably less than about 1,000 nucleic acids or base pairs. Similarly, RNA sequences, reverse sequences, complementary sequences, antisense sequences, and the like, corresponding to the polynucleotides of the present invention, may be routinely ascertained and obtained using the cDNA sequences identified as SEQ ID NO: 1-14, 20, 22-62, 81-86 and 88-127. The polynucleotides identified as SEQ ID NO: 1-14, 20, 22-62, 81-86 and 88-127, and their extensions, may contain open reading frames ("ORFs") or partial open reading frames encoding polypeptides. Additionally, open reading frames encoding polypeptides may be identified in extended or full length sequences corresponding to the sequences set out as SEQ ID NO: 1-14, 20, 22-62, 81-86 and 88-127. Open reading frames may be identified using techniques that are well known in the art. These techniques include, for example, analysis for the location of known start and stop codons, most likely reading frame identification based on codon frequencies, etc. Suitable tools and software for ORF analysis include, for example, "GeneWise", available from The Sanger Center, " Wellcome Trust Genome Campus, Hinxton, Cambridge, CB10 ISA, United Kingdom; "Diogenes", available from Computational Biology Centers, University of Minnesota, Academic Health Center, UMHG Box 43, Minneapolis MN 55455 and "GRAIL", available from the Informatics Group, Oak Ridge National Laboratories, Oak Ridge, Tennessee TN. Open reading frames and portions of open reading frames may be identified in the polynucleotides of the present invention. ' Once a partial open reading frame is identified, the polynucleotide may be extended in the area of the partial open reading frame using techniques that are well known in the art until the polynucleotide for the full open reading frame is identified. Thus, open reading frames encoding polypeptides may be identified using the polynucleotides of the present invention. Once open reading frames are identified in the polynucleotides of the present invention, the open reading frames may be isolated and/or synthesized. Expressible genetic constructs comprising the open reading frames and suitable promoters, initiators, terminators, etc., which are well known in the art, may then be constructed. Such genetic constructs may be introduced into a host cell to express the polypeptide encoded by the open reading frame. Suitable host cells may include various prokaryotic and eukaryotic cells, including plant cells, mammalian cells, bacterial cells, algae and the like. Polypeptides encoded by the polynucleotides of the present invention may be expressed and used in various assays to determine their biological activity. Such polypeptides may be used to raise antibodies, to isolate corresponding interacting proteins or other compounds, and to quantitatively determine levels of interacting proteins or other compounds. The term "polypeptide", as used herein, encompasses amino acid chains of any length including full length proteins, wherein amino acid residues are linked by covalent peptide bonds. Polypeptides of the present invention may be isolated and purified natural products, or may be produced partially or wholly using recombinant techniques. The term "polypeptide encoded by a polynucleotide" as used herein, includes polypeptides encoded by a nucleotide sequence which includes the partial isolated DNA sequences of the present invention. In a related aspect, polypeptides are provided that comprise at least a functional portion of a polypeptide having a sequence selected from the group consisting of sequences provided in SEQ ID NO: 63-80, 87 and 130, and variants thereof. As used herein, the "functional portion" of a polypeptide is that portion which contains the active site essential for affecting the function of the polypeptide, for example, the portion of the molecule that is capable of binding one or more reactants. The active site may be made up of separate portions present on one or more polypeptide chains and will generally exhibit high binding affinity. Functional portions of a polypeptide may be identified by first preparing fragments of the polypeptide by either chemical or enzymatic digestion of the polypeptide, or by mutation analysis of the polynucleotide that encodes the polypeptide and subsequent expression of the resulting mutant polypeptides. The polypeptide fragments or mutant polypeptides are then tested to determine which portions retain biological activity, using, for example, the representative assays provided below. A functional portion comprising an active site may be made up of separate portions present on one or more polypeptide chains and generally exhibits high substrate specificity. Portions and other variants of the inventive polypeptides may be generated by synthetic or recombinant means. Synthetic polypeptides having fewer than about 100 amino acids, and generally fewer than about 50 amino acids, may be generated using techniques well known to those of ordinary skill in the art. For example, such polypeptides may be synthesized using any of the commercially available solid-phase techniques, such as the Merrifield solid-phase synthesis method, wherein amino acids are sequentially added to a growing amino acid chain. (Merrifield, J. Am. Chem. Soc. 85: 2149-2154, 1963). Equipment for automated synthesis of polypeptides is commercially available from suppliers such as Perlcin Elmer / Applied Biosystems, Inc. (Foster City, California), and may be operated according to the manufacturer's instructions. Variants of a native polypeptide may be prepared using standard mutagenesis techniques, such as oligonucleotide-directed site- specific mutagenesis (Kunkel, Proc. Natl. Acad. Sci. USA 82: 488-492, 1985). Sections of DNA sequences may also be removed using standard techniques to permit preparation of truncated polypeptides. As used herein, the term "variant" comprehends nucleotide or amino acid sequences different from the specifically identified sequences, wherein one or more nucleotides or amino acid residues is deleted, substituted, or added. Variants may be naturally occurring allelic variants, or non-naturally occurring variants. Variant sequences (polynucleotide or polypeptide) preferably exhibit at least 50%, more preferably at least 75%, and most preferably at least 90% identity to a sequence of the present invention. The percentage identity is determined by aligning the two sequences to be compared as described below, determining the number of identical residues in the aligned portion, dividing that number by the total number of residues in the inventive (queried) sequence, and multiplying the result by 100. Polynucleotide and polypeptide sequences may be aligned, and percentage of identical residues in a specified region may be determined against other polynucleotide and polypeptide sequences, using computer algorithms that are publicly available. Two exemplary algorithms for aligning and identifying the similarity of polynucleotide sequences are the BLASTN and FASTA algorithms. Polynucleotides may also be analyzed using the BLASTX algorithm, which ■ compares the six-frame conceptual translation products of a nucleotide query sequence (both strands) against a protein sequence database. The similarity of polypeptide sequences may be examined using the BLASTP algorithm. The BLASTN algorithm Version 2.0.4 [Feb-24-1998], Version 2.0.6 [Sept-16-1998] and Version 2.0.11 [Jan-20-2000], set to the default parameters described in the documentation and distributed with the algorithm, are preferred for use in the determination of polynucleotide variants according to the present invention. The BLASTP algorithm, is preferred for use in the determination of polypeptide variants according to the present invention. The use of the BLAST family of algorithms, including BLASTN, BLASTP, and BLASTX, is described in the publication of Altschul, et al., "Gapped BLAST and PSI-BLAST: a new generation of protein database search programs," Nucleic Acids Res. 25: 3389-3402, 1997. The BLASTN software is available on the NCBI anonymous FTP server (ftp://ncbi.nlm.nih.gov) under /blast/executables/ and is available from the National Center for Biotechnology Information (NCBI), National Library of Medicine, Building 38A, Room 8N805, Bethesda, MD 20894 USA. The FASTA software package is available from the University of Virginia (University of Virginia, PO Box 9025, Charlottesville, VA 22906-9025). Version 2.0u4, February 1996, set to the default parameters described in the documentation and distributed with the algorithm, may be used in the determination of variants according to the present invention. The use of the FASTA algorithm is described in Pearson and Lipman, "Improved Tools for Biological Sequence Analysis/' Proc. Natl. Acad. Sci. USA 85: 2444-2448, 1988; and Pearson, "Rapid and Sensitive Sequence Comparison with FASTP and FASTA," Methods in Enzymol. 183: 63-98, 1990. The following running parameters are preferred for determination of alignments and similarities using BLASTN that contribute to the E values and percentage identity for polynucleotide sequences: Unix running command: blastall -p blastn -d embldb -e 10 -GO - E0 -r 1 -v 30 -b 30 -i queryseq -o results; the parameters are: -p Program Name [String]; - d Database [String]; -e Expectation value (E) [Real]; -G Cost to open a gap (zero invokes default behavior) [Integer]; -E Cost to extend a gap (zero invokes default behavior) [Integer]; -r Reward for a nucleotide match (BLASTN only) [Integer]; -v Number of one-line descriptions (V) [Integer]; -b Number of alignments to show (B) [Integer]; -i Query File [File In]; and -o BLAST report Output File [File Out] Optional. The following running parameters are preferred for determination of alignments and similarities using BLASTP- that contribute to the E values and percentage identity of polypeptide sequences: blastall -p blastp -d swissprotdb -e 10 -G O -E 0 -v 30 -b 30 -i queryseq -o results; the parameters are: -p Program Name [String]; -d Database [String]; -e Expectation value (E) [Real]; -G Cost to open a gap (zero invokes default behavior) [Integer]; -E Cost to extend a gap (zero invokes default behavior) [Integer]; -v Number of one-line descriptions (v) [Integer]; -b Number of alignments to show (b) [Integer]; -I Query File [File In]; -o BLAST report Output File [File Out] Optional. The "hits" to one or more database sequences by a queried sequence produced by BLASTN, FASTA, BLASTP or a similar algorithm, align and identify similar portions of sequences. The hits are arranged in order of the degree of similarity and the length of sequence overlap. Hits to a database sequence generally represent an overlap over only a fraction of the sequence length of the queried sequence. The BLASTN, FASTA and BLASTP algorithms also produce "Expect" values for alignments. The Expect value (E) indicates the number of hits one can "expect" to see over a certain number of contiguous sequences by chance when searching a database of a certain size. The Expect value is used as a significance threshold for determining whether the hit to a database, such as the preferred EMBL database, indicates true similarity. For example, an E value of 0.1 assigned to a polynucleotide hit is interpreted as meaning that in a database of the size of the EMBL database, one might expect to see 0.1 matches over the aligned portion of the sequence with a similar score simply by chance. By this criterion, the aligned and matched portions of the polynucleotide sequences then have a probability of 90% of being the same. For sequences having an E value of 0.01 or less over aligned and matched portions, the probability of finding a match by chance in the EMBL database is 1% or less using the BLASTN or FASTA algorithm. According to one embodiment, "variant" polynucleotides and polypeptides, with reference to each of the polynucleotides and polypeptides of the present invention, preferably comprise sequences having the same number or fewer nucleic or amino acids than each of the polynucleotides or polypeptides of the present invention and producing an E value of 0.01 or less when compared to the polynucleotide or polypeptide of the present invention. That is, a variant polynucleotide or polypeptide is any sequence that has at least a 99% probability of being the same as the polynucleotide or polypeptide of the present invention, measured as having an E value of 0.01 or less using the BLASTN, FASTA, or BLASTP algorithms set at parameters described above. According to a preferred embodiment, a variant polynucleotide is a sequence having the same number or fewer nucleic acids than a polynucleotide of the present invention that has at least a 99% probability of being the same as the polynucleotide of the present invention, measured as having an E value of 0.01 or less using the BLASTN or FASTA algorithms set at parameters described above. Similarly, according to a preferred embodiment, a variant polypeptide is a sequence having the same number or fewer amino acids than a polypeptide of the present invention that has at least a 99% probability of being the same as a polypeptide of the present invention, measured as having an E value of 0.01 or less using the BLASTP algorithm set at the parameters described above. Alternatively, variant polynucleotides of the present invention hybridize to the polynucleotide sequences recited in SEQ ID NO: 1-14, 20, 22-62, 81-86 and 88-127, or complements, reverse sequences, or reverse complements of those sequences under stringent conditions. As used herein, "stringent conditions" refers to prewashing in a solution of 6X SSC, 0.2% SDS; hybridizing at 65°C, 6X SSC, 0.2% SDS overnight; followed by two washes of 30 minutes each in IX SSC, 0.1% SDS at 65° C and two washes of 30 minutes each in 0.2X SSC, 0.1% SDS at 65°C. The present invention also encompasses polynucleotides that differ from the disclosed sequences but that, as a consequence of the discrepancy of the genetic code, encode a polypeptide having similar activity to a polypeptide encoded by a polynucleotide of the present invention. Thus, polynucleotides comprising sequences that differ from the polynucleotide sequences recited in SEQ ID NO: 1-14, 20, 22-62, 81-86 and 88-127, or complements, reverse sequences, or reverse complements thereof, as a result of conservative substitutions are contemplated by and encompassed within the present invention. Additionally, polynucleotides comprising sequences that differ from the polynucleotide sequences recited in SEQ ID NO: 1-14, 20, 22-62, 81-86 and 88-127, or complements, reverse complements or reverse sequences thereof, as a result of deletions and/or insertions totaling less than 10% of the total sequence length are also contemplated by and encompassed within the present invention. Similarly, polypeptides comprising sequences that differ from the polypeptide sequences recited in SEQ ID NO: 63-80, 87 and 130, as a result of amino acid substitutions, insertions, and/or deletions totaling less than 10% of the total sequence length are contemplated by an encompassed within the present invention. In certain embodiments, variants of the inventive polypeptides and polynucleotides possess biological activities that are the same or similar to those of the inventive polypeptides or polynucleotides. Such variant polynucleotides function as promoter sequences and are thus capable of modifying gene expression in a plant. The polynucleotides of the present invention may be isolated from various libraries, or may be synthesized using techniques that are well known in the art. The polynucleotides may be synthesized, for example, using automated oligonucleotide synthesizers (e.g., Beckman Oligo 1000M DNA Synthesizer) to obtain polynucleotide segments of up to 50 or more nucleic acids. A plurality of such polynucleotide segments may then be ligated using standard DNA manipulation techniques that are well known in the art of molecular biology. One conventional and exemplary polynucleotide synthesis technique involves synthesis of a single stranded polynucleotide segment having, for example, 80 nucleic acids, and hybridizing that segment to a synthesized complementary 85 nucleic acid segment to produce a 5-nucleotide overhang. The next segment may then be synthesized in a. similar fashion, with a 5-nucleotide overhang on the opposite strand. The "sticky" ends ensure proper ligation when the two portions are hybridized. In this way, a complete polynucleotide of the present invention may be synthesized entirely in vitro. Polynucleotides of the present invention also comprehend polynucleotides comprising at least a specified number of contiguous residues (x-mers) of any of the polynucleotides identified as SEQ ID NO: 1-14, 20, 22-62, 81-86 and 88-127, complements, reverse sequences, and reverse complements of such sequences, and their variants. Similarly, polypeptides of the present invention comprehend polypeptides comprising at least a specified number of contiguous residues (x-mers) of any of the polypeptides identified as SEQ ID NO: 63-80, 87 and 130, and their variants. As used herein, the term "x-mer," with reference to a specific value of "x," refers to a sequence comprising at least a specified number ("x") of contiguous residues of any of the polynucleotides identified as SEQ ID NO: 1-14, 20, 22-62, 81-86 and 88-127, or the polypeptides identified as SEQ ID NO: 63-80, 87 and 130. According to preferred embodiments, the value of x is preferably at least 20, more preferably at least 40, more preferably yet at least 60, and most preferably at least 80. Thus, polynucleotides and polypeptides of the present invention comprise a 20-mer, a 40-mer, a 60- mer, an 80-mer, a 100-mer, a 120-mer, a 150-mer, a 180-mer, a 220-mer, a 250-mer, a 300- mer, 400-mer, 500-mer or 600-mer of a polynucleotide or polypeptide identified as SEQ ID NO: 1-14, 20, 22-62, 81-86 and 88-127, and variants thereof. As noted above, the inventive polynucleotide promoter sequences may be employed in genetic constructs to drive transcription and/or expression of a polynucleotide of interest. The polynucleotide of interest may be either endogenous or heterologous to an organism, for example a plant, to be transformed. The inventive genetic constructs may thus be employed to modulate levels of transcription and/or expression of a polynucleotide, for example gene, that is present in the wild-type plant, or may be employed to provide transcription and/or expression of a DNA sequence that is not found in the wild-type plant. In certain embodiments, the polynucleotide of interest comprises an open reading frame that encodes a target polypeptide. The open reading frame is inserted in the genetic construct in either a sense or antisense orientation, such that transformation of a target plant with the genetic construct will lead to a change in the amount of polypeptide compared to the wild-type plant. Transformation with a genetic construct comprising an open reading frame in a sense orientation will generally result in over-expression of the selected polypeptide, while transformation with a genetic construct comprising an open reading frame in an antisense orientation will generally result in reduced expression of the selected polypeptide. A population of plants transformed with a genetic construct comprising an open reading frame in either a sense or antisense orientation may be screened for increased or reduced expression of the polypeptide in question using techniques well known to those of skill in the art, and plants having the desired phenotypes may thus be isolated. Alternatively, expression of a target polypeptide may be inhibited by inserting a portion of the open reading frame, in either sense or antisense orientation, in the genetic construct. Such portions need not be full-length but preferably comprise at least 25 and.more preferably at least 50 residues of the open reading frame. A much longer portion or even the full length DNA corresponding to the complete open reading frame may be employed. The portion of the open reading frame does not need to be precisely the same as the endogenous sequence, provided that there is sufficient sequence similarity to achieve inhibition of the target gene. Thus a sequence derived from one species may be used to inhibit expression of a gene in a different species. In further embodiments, the inventive genetic constructs comprise a polynucleotide including an untranslated, or non-coding, region of a gene coding for a target polypeptide, or a polynucleotide complementary to such an untranslated region. Examples of untranslated regions which may be usefully employed in such constructs include introns and 5'- untranslated leader sequences. Transformation of a target plant with such a genetic construct may lead to a reduction in the amount of the polypeptide expressed in the plant by the process of cosuppression, in a manner similar to that discussed, for example, by Napoli et al., Plant Cell 2:279-290, 1990 and de Carvalho Niebel et al., Plant Cell 7:347-358, 1995. Alternatively, regulation of polypeptide expression can be achieved by inserting appropriate sequences or subsequences (e.g. DNA or RNA) in ribozyme constructs (Mclntyre and Manners, Transgenic Res. 5(4):257-262, 1996). Ribozymes are synthetic RNA molecules that comprise a hybridizing region complementary to two regions, each of which comprises at least 5 contiguous nucleotides in a mRNA molecule encoded by one of the inventive polynucleotides. Ribozymes possess highly specific endonuclease activity, which autocatalytically cleaves the mRNA. The polynucleotide of interest, such as a coding sequence, is operably linked to a polynucleotide promoter sequence of the present invention such that a host cell is able to transcribe an RNA from the promoter sequence linked to the polynucleotide of interest. The polynucleotide promoter sequence is generally positioned at the 5' end of the polynucleotide to be transcribed. Use of a constitutive promoter, such as the Pinus radiata ubiquitin polynucleotide promoter sequence of SEQ ID NO: 2 and 3' or the Eucalyptus grandis ubiquitin polynucleotide promoter sequence contained within SEQ ID NO: 34, will affect transcription of the polynucleotide of interest in all parts of the transformed plant. Use of a tissue specific promoter, such as the leaf-specific promoters of SEQ ID NO: 9-11, the root- specific promoters of SEQ ID NO: 13 and 14, the flower-specific promoters of SEQ ID NO: 29-33, 59 and 89-90, the pollen-specific promoters of SEQ ID NO: 49-55 and 94, the bud- specific promoter of SEQ ID NO: 40 or the meristem- specific promoter of SEQ ID NO: 45, will result in production of the desired sense or antisense RNA only in the tissue of interest. Temporally regulated promoters, such as the xylogenesis-specific promoters of SEQ ID NO: 5, 41-44 and 92, can be employed to effect modulation of the rate of DNA transcription at a specific time during development of a transformed plant. With genetic constructs employing inducible gene promoter sequences, the rate of DNA transcription can be modulated by external stimuli, such as light, heat, anaerobic stress,. alteration in nutrient conditions and the like. The inventive genetic constructs further comprise a gene termination sequence which is located 3' to the polynucleotide of interest. A variety of gene termination sequences which may be usefully employed in the genetic constructs of the present invention are well known in the art. One example of such a gene termination sequence is the 3' end of the Agrobacterium tumefaciens nopaline synthase gene. The gene termination sequence may be endogenous to the target plant or may be exogenous, provided the promoter is functional in the target plant. For example, the termination sequence may be from other plant species, plant viruses, bacterial plasmids and the like. The genetic constructs of the present invention may also contain a selection marker that is effective in cells of the target organism, such as a plant, to allow for the detection of transformed cells containing the inventive construct. Such markers, which are well known in the art, typically confer resistance to one or more toxins. One example of such a marker is the NPTII gene whose expression results in resistance to kanamycin or hygromycin, antibiotics which are usually toxic to plant cells at a moderate concentration (Rogers et al., in Weissbach A and H, eds. Methods for Plant Molecular Biology, Academic Press Inc.: San Diego, CA, 1988). Transformed cells can thus be identified by their ability to grow in media containing the antibiotic in question. Alternatively, the presence of the desired construct in transformed cells can be determined by means of other techniques well known in the art, such as Southern and Western blots. Techniques for operatively linking the components of the inventive genetic constructs are well known in the art and include the ' use of synthetic linkers containing one or more restriction endonuclease sites as described, for example, by Sambrook et al., (Molecular cloning: a laboratory manual, CSHL Press: Cold Spring Harbor, NY, 1989). The genetic construct of the present invention may be linked to a vector having at least one replication system, for example E. coli, whereby after each manipulation, the resulting construct can be cloned and sequenced and the correctness of the manipulation determined. The genetic constructs of the present invention may be used to transform a variety of target organisms including, but not limited to, plants. Plants which may be transformed using the inventive constructs include both monocotyledonous angiosperms (e.g., grasses, corn, grains, oat, wheat and barley) and dicotyledonous angiosperms (e.g., Arabidopsis, tobacco, legumes, alfalfa, oaks, eucalyptus, maple), and Gymnosperms (e.g., Scots pine; see Aronen, Finnish Forest Res. Papers, Vol. 595, 1996), white spruce (Ellis et al., Biotechnology 11:84- 89, 1993), and larch (Huang et al, In Vitro Cell 27:201-207, 1991). In a preferred embodiment, the inventive genetic constructs are employed to transform woody plants, herein defined as a tree or shrub whose stem lives for a number of years and increases in diameter each year by the addition of woody tissue. Preferably the target plant is selected from the group consisting of eucalyptus and pine species, most preferably from the group consisting of Eucalyptus grandis and Pinus radiata. Other species which may be usefully transformed with the genetic constructs of the present invention include, but are not limited to: pines such as Pinus banksiana, Pinus brutia, Pinus caribaea, Pinus clausa, Pinus contorta, Pinus coulteri, Pinus echinata, Pinus eldarica, Pinus ellioti, Pinus jeffreyi, Pinus lambertiana, Pinus monticola, Pinus nigra, Pinus palustrus, Pinus pinaster, Pinus ponderosa, Pinus resinosa, Pinus rigida, Pinus serotina, Pinus strobus, Pinus sylvestris, Pinus taeda, Pinus virginiana; other gymnosperms, such as Abies amabilis, Abies balsamea, Abies concolor, Abies grandis, Abies lasiocarpa, Abies magnifica, Abies procera, Chamaecyparis lawsoniona, Chamaecyparis nootkatensis, Chamaecyparis thyoides, Huniperus virginiana, Larix decidua, Larix laricina, Larix leptolepis, Larix occidentalis, Larix siberica, Libocedrus decurrens, Picea abies, Picea engelmanni, Picea glauca, Picea mariana, Picea pungens, Picea rubens, Picea sitchensis, Pseudotsuga menziesii, Sequoia gigantea, Sequoia sempervirens, Taxodiuin distichum, Tsuga canadensis, Tsuga heterophyϊla, Tsuga mertensiana, Thuja occidentalis, Thuja plicata; and Eucalypts, such as Eucalyptus alba, Eucalyptus bancroftii, Eucalyptus botyroides, Eucalyptus bridgesiana, Eucalyptus calophylla, Eucalyptus camaldulensis, Eucalyptus citriodora, Eucalyptus cladocalyx, Eucalyptus coccifera, Eucalyptus curtisii, Eucalyptus dalrympleana, Eucalyptus deglupta, Eucalyptus delagatensis, Eucalyptus diversicolor, ' Eucalyptus dunnii, Eucalyptus ficifolia, Eucalyptus globulus, Eucalyptus gomphocephala, Eucalyptus gunnii, Eucalyptus henryi, Eucalyptus laevopinea, Eucalyptus macarthurii, Eucalyptus macrorhyncha, Eucalyptus maculata, Eucalyptus marginata, Eucalyptus megacarpa,- Eucalyptus melliodora, Eucalyptus nicholii, Eucalyptus nitens, Eucalyptus nova-anglica, Eucalyptus obliqua, Eucalyptus obtusiflora, Eucalyptus oreades, Eucalyptus pauciflora, Eucalyptus polybractea, Eucalyptus regnans, Eucalyptus resinifera, Eucalyptus robusta, Eucalyptus rudis, Eucalyptus saligna, Eucalyptus sideroxylon, Eucalyptus stuartiana, Eucalyptus tereticornis, Eucalyptus torelliana, Eucalyptus urnigera, Eucalyptus urophylla, Eucalyptus viminalis, Eucalyptus viridis, Eucalyptus wandoo and Eucalyptus youmanni; and hybrids of any of these species. Techniques for stably incorporating genetic constructs into the genome of target plants are well known in the art and include Agrobacterium tumefaciens mediated introduction, electroporation, protoplast fusion, injection into reproductive organs, injection into immature embryos, high velocity projectile introduction and the like. The choice of technique will depend upon the target plant to be transformed. For example, dicotyledonous plants and certain monocots and gymnosperms may be transformed by Agrobacterium Ti plasmid technology, as described, for example by Bevan, Nucleic Acids Res. 12:8711-8721, 1984. Targets for the introduction of the genetic constructs of the present invention include tissues, such as leaf tissue, dissociated cells, protoplasts, seeds, embryos, meristematic regions; cotyledons, hypocotyls, and the like. The preferred method for transforming eucalyptus and pine is a biolistic method using pollen (see, for example, Aronen, Finnish Forest Res. Papers, Vol. 595, 53pp, 1996) or easily regenerable embryonic tissues. Once the cells are transformed, cells having the inventive genetic construct incorporated in their genome may be selected by means of a marker, such as the kanamycin resistance marker discussed above. Transgenic cells may then be cultured in an appropriate medium to regenerate whole plants, using techniques well known in the art. In the case of protoplasts, the cell wall is allowed to reform under appropriate osmotic conditions. In the case of seeds or embryos, an appropriate germination or callus initiation medium is employed. For explants, an appropriate regeneration medium is used. Regeneration of plants is well established for many species. For a review of regeneration of forest trees see Dunstan et al., "Somatic embryogenesis in woody plants," in Thorpe TA, ed., In Vitro Embryogenesis of Plants (Current Plant Science and Biotechnology in Agriculture Vol. 20), Chapter 12, pp. 471-540, 1995. Specific protocols for the regeneration of spruce are discussed by Roberts et al., "Somatic embryogenesis of spruce," in Redenbaugh K, ed., Synseed: applications of synthetic seed to crop improvement, CRC Press: Chapter 23, pp. 427-449, 1993). Transformed plants having the desired phenotype may be selected using techniques well known in the art. The resulting transformed plants may be reproduced sexually or asexually, using methods well known in the art, to give successive generations of transgenic plants. As discussed above, the production of RNA in target cells can be controlled by choice of the promoter sequence, or by selecting the number of functional copies or the site of integration of the polynucleotides incorporated into the genome of the target host. A target organism may be transformed with more than one genetic construct of the present invention, thereby modulating the activity of more than gene. Similarly, a genetic construct may be assembled containing more than one open reading frame coding for a polypeptide of interest or more than one untranslated region of a gene coding for such a polypeptide. The isolated polynucleotides of the present invention also have utility in genome mapping, in physical mapping, and in positional cloning of genes. As detailed below, the polynucleotide sequences identified as SEQ ID NO: 1-14, 20, 22-62, 81-86 and 88-127, and their variants, may be used to design oligonucleotide probes and primers. Oligonucleotide probes designed using the polynucleotides of the present invention may be used to detect the presence and examine the expression patterns of genes in any organism having sufficiently similar DNA and RNA sequences in their cells using techniques that are well known in the art, such as slot blot DNA hybridization techniques. Oligonucleotide primers designed using the polynucleotides of the present invention may be used for PCR amplifications. Oligonucleotide probes and primers designed using the polynucleotides of the present invention may also be used in connection with various microarray technologies, including the microarray technology of Affymetrix (Santa Clara, CA). As used herein, the term "oligonucleotide" refers to a relatively short segment of a polynucleotide sequence, generally comprising between 6 and 60 nucleotides, and comprehends both probes for use in hybridization assays and primers for use in the amplification of DNA by polymerase chain reaction. An oligonucleotide probe or primer is described as "corresponding to" a polynucleotide of the present invention, including one of the sequences set out as SEQ ID NO: 1-14, 20, 22-62, 81-86 and 88-127, or a variant, if the oligonucleotide probe or primer, or its complement, is contained within one of the sequences set out as SEQ ID NO: 1-14, 20, 22-62, 81-86 and 88-127, or a variant of one of the specified sequences. Oligonucleotide probes and primers of the present invention are substantially complementary to a polynucleotide disclosed herein. Two single stranded sequences are said to be substantially complementary when the nucleotides of one strand, optimally aligned and compared, with the appropriate nucleotide insertions and/or deletions, pair with at least 80%, preferably at least 90% to 95% and more preferably at least 98% to 100% of the nucleotides of the other strand. Alternatively, substantial complementarity exists when a first DNA strand will selectively hybridize to a second DNA strand under stringent hybridization conditions. Stringent hybridization conditions for determining complementarity include salt conditions of less than about 1 M, more usually less than about 500 mM, and preferably less than about 200 mM. Hybridization temperatures can be as low as 5°C, but are generally greater than about 22°C, more preferably greater than about 30°C, and most preferably greater than about 37°C. Longer DNA fragments may require higher hybridization temperatures for specific hybridization. Since the stringency of hybridization may be affected by other factors such as probe composition, presence of organic solvents and extent of base mismatching, the combination of parameters is more important than the absolute measure of any one alone. In specific embodiments, the oligonucleotide probes and/or primers comprise at least about 6 contiguous residues, more preferably at least about 10 contiguous residues, and most preferably at least about 20 contiguous residues complementary to a polynucleotide sequence of the present invention. Probes and primers of the present invention may be from about 8 to 100 base pairs in length or, preferably from about 10 to 50 base pairs in length or, more preferably from about 15 to 40 base pairs in length. The probes can be easily selected using procedures well known in the art, taking into account DNA-DNA hybridization stringencies, annealing and melting temperatures, and potential for formation of loops and other factors, which are well known in the art.. Preferred techniques for designing PCR primers are disclosed in Dieffenbach, CW and Dyksler, GS. PCR Primer: a laboratory manual, CSHL Press: Cold Spring Harbor, NY, 1995. A software program suitable for designing probes, and especially for designing PCR primers, is available from Premier Biosoft International, 3786 Corina Way, Palo Alto, CA 94303-4504. A plurality of oligonucleotide probes or primers corresponding to a polynucleotide of the present invention may be provided in a kit form. Such kits generally comprise multiple DNA or oligonucleotide probes, each probe being specific for a polynucleotide sequence. Kits of the present invention may comprise one or more probes or primers corresponding to a polynucleotide of the present invention, including a polynucleotide sequence identified in SEQ ID NO: 1-14, 20, 22-62, 81-86 and 88-120. In one embodiment useful for high-throughput assays, the oligonucleotide probe kits of the present invention comprise multiple probes in an array format, wherein each probe is immobilized at a predefined, spatially addressable location on the surface of a solid substrate. Array formats which may be usefully employed in the present invention are disclosed, for example, in U.S. Patents No. 5,412,087 and 5,545,451; and PCT Publication No. WO 95/00450, the disclosures of which are hereby incorporated by reference. The polynucleotides of the present invention may also be used to tag or identify an organism or reproductive material therefrom. Such tagging may be accomplished, for example, by stably introducing a non-disruptive non-functional heterologous polynucleotide identifier into an organism, the polynucleotide comprising one of the polynucleotides of the present invention. The following examples are offered by way of illustration and not by way of limitation. EXAMPLE 1 Isolation and Characterization of a Ubiquitin Gene Promoter from Pinus radiata Pinus radiata cDNA expression libraries were constructed and screened as follows. mRNA was extracted from plant tissue using the protocol of Chang et al., Plant Molecular Biology Reporter 11:113-116, 1993 with minor modifications. Specifically, samples were dissolved in CPC-RNAXB (100 mM Tris-Cl, pH 8,0; 25 mM EDTA; 2.0 M NaCl; 2%CTAB; 2% PVP and 0.05% Spermidine+JHCl) and extracted with chloroforrmisoamyl alcohol, 24:1. mRNA was precipitated with ethanol and the total RNA preparate was purified using a Poly(A) Quik mRNA Isolation Kit (Stratagene, La lolla, CA). A cDNA expression library was constructed from the purified mRNA by reverse transcriptase synthesis followed by insertion of the resulting cDNA clones in Lambda ZAP using a ZAP Express cDNA Synthesis Kit (Stratagene), according to the manufacturer's protocol. The resulting cDNAs were packaged using a Gigapack II Packaging Extract (Stratagene) employing 1 μl of sample DNA from the 5 μl ligation mix. Mass excision of the library was done using XLl-Blue MRF' cells and XLOLR cells (Stratagene) with ExAssist helper phage (Stratagene). The excised phagemids were diluted with NZY broth (Gibco BRL, Gaithersburg, MD) and plated out onto LB-kanamycin agar plates containing X-gal and isopropylthio-beta-galactoside (IPTG). Of the colonies plated and picked for DNA miniprep, 99% contained an insert suitable for sequencing. Positive colonies were cultured in NZY broth with kanamycin and cDNA was purified by means of alkaline lysis and polyethylene glycol (PEG) precipitation. Agarose gel at 1% was used to screen sequencing templates for chromosomal contamination. Dye primer sequences were prepared using a Turbo Catalyst 800 machine (Perlcin Elmer/ Applied Biosystems Division, Foster City, CA) according to the manufacturer's protocol. DNA sequence for positive clones was obtained using a Perldn Elmer/Applied Biosystems Division Prism 377 sequencer. cDNA clones were sequenced first from the 5' end and, in some cases, also from the 3' end. For some clones, internal sequence was obtained using subcloned fragments. Subcloning was performed using standard procedures of restriction mapping and subcloning to pBluescript II SK+ vector. As described below, one of the most abundant sequences identified was a ubiquitin gene, hereinafter referred to as the "Super-Ubiquitin or SU" gene. Isolation of cDNA clones containing the ubiquitin gene Sequences of cDNA clones with homology to the ubiquitin gene were obtained from high-throughput cDNA sequencing as described above. Sequences from several independent clones were assembled in a contig and a consensus sequence was generated from overlapping clones. The determined nucleotide sequence of the isolated Super Ubiquitin clone, comprising the promoter region (including an intron), coding region and 3' untranslated region (UTR) is provided in SEQ ID NO: 1. The 5' UTR is represented by residues 1 to 2,064, the intron by residues 1,196 to 2,033, and the coding region of the gene, which contains three direct repeats, by residues 2,065 to 2J51. The 3' UTR is 328 residues long (residues 2J55 to 3,083). The nucleotide sequence of the Super Ubiquitin promoter region only, including the intron, is given in SEQ ID NO: 2. The nucleotide sequence of the Super Ubiquitin promoter region only, excluding the intron, is given in SEQ ID NO: 3. The predicted amino acid sequence for the Pinus radiata Super Ubiquitin is provided in SEQ ID NO: 80. Ubiquitin proteins function as part of a protein degradation pathway, in which they covalently attach to proteins, thereby targeting them for degradation (for a review, see Belknap and Garbarino, Trends in Plant Sciences 1:331-335, 1996). The protein is produced from a precursor polypeptide, encoded by a single mRNA. The Super Ubiquitin mRNA contains three copies of the ubiquitin monomer. Cloning of the Super Ubiquitin Promoter Fragments of the Super Ubiquitin promoter were cloned by two different PCR-based approaches. Method 1: Long Distance Gene Walking PCR Using "Long Distance Gene Walking" PCR (Min and Powell, Biotechniques 24:398- 400, 1998), a 2 kb fragment was obtained that contained the entire coding region of the ubiquitin gene, a 900 bp intron in the 5' UTR and approximately 100 bp of the promoter. To generate this fragment, 2 nested primers were designed from the 3' UTR of the Super Ubiquitin cDNA sequence isolated from pine. Generally, the 5' UTR is used for primer design to amplify upstream sequence. However, the available 5' UTR of Super Ubiquitin was very short, and two initial primers derived from this region failed to amplify any fragments. Therefore, the primers of SEQ ID NO: 15 and 16 were designed from the 3' UTR. The method involved an initial, linear PCR step with pine genomic DNA as template using the primer of SEQ ID -NO: 15, and subsequent C-tailing of the single stranded DNA product using terminal transferase. The second PCR-step used these fragments as template for amplification with the primer of SEQ ID NO: 16 and primer AP of SEQ ID NO: 17. The AP primer was designed to bind to the polyC tail generated by the terminal transferase. Both primers (SEQ ID NO: 16 and 17) contained a 5' -Notl restriction site for the cloning of products into the Notl site of a suitable vector. The final PCR product contained fragments of different sizes. These fragments were separated by electrophoresis and the largest were purified from the gel, digested with restriction endonuclease Not! and cloned in the Notl site of expression vector pBK-CMV (Stratagene, La Jolla, CA). The largest of these clones contained the complete coding region of the gene (no introns were found in the coding sequence) and a 5' UTR which contained a 900 bp intron. Method 2: "Genome Walker" kit The Super Ubiquitin gene promoter was cloned using a "Genome Walker" kit (Clontech, Palo Alto, CA). This is also a PCR-based method, which requires two PCR primers to be constructed, one of which must be gene-specific. Although the ubiquitin coding region is highly conserved, the 5' UTR from different ubiquitin genes is not conserved and could therefore be used to design a gene-specific primer. A 2J kb fragment was amplified and subcloned in pGEM-T-easy (Promega, Madison, WI). Analysis by PCR and DNA sequencing showed that the clone contained 5' UTR sequence of the Super Ubiquitin gene, including the 900 bp intron and approximately 1 kb of putative promoter region. An intron in the 5' UTR is a common feature of plant polyubiquitin genes and may be involved in determining gene expression levels. The gene specific primers used for these PCR reactions are provided in SEQ ID NO: 18 and 19. Expression of Super Ubiquitin Using primers derived from the gene-specific 5' and 3' UTR sequences, expression levels of Super Ubiquitin in different plant tissues was examined by means of RT-PCR. Super Ubiquitin was found to be expressed in all plant tissues examined, including branch phloem and xylem, feeder roots, fertilized cones, needles, one year old cones, pollen sacs, pollinated cones, root xylem, shoot buds, structural roots, trunk phloem and trunk. Expression of Super Ubiquitin in plant tissues was also demonstrated in a Northern blot assay using a PCR probe prepared from the 5 'UTR. Functional analysis of the Super Ubiquitin Promoter To test the function of the Super Ubiquitin promoter in plants, Arabidopsis thaliana was transformed with constructs containing the reporter gene for Green Fluorescent Protein (GFP) operably linked to either the Super Ubiquitin promoter of SEQ ID NO: 2 or SEQ ID NO: 3 (i.e., either with or without the intron). Constructs lacking a promoter were used as a negative control, with a plant T-DNA vector carrying a CaMV 35S promoter cloned in front of GFP being used as a positive control. The constructs were introduced into Arabidopsis via Agrobacterium-medi&ted transformation. All the plant culture media were according to the protocol of Valvelcens and Van Montagu, Proc. Natl. Acad. Sci. USA 85:5536-5540, 1988 with minor modifications. For root transformation, sterilized seeds were placed in a line on the surface of germination medium, the plates were placed on their sides to facilitate root harvesting, and the seeds were grown for two weeks at 24°C with a 16 h photoperiod. Expression of the constructs was measured by determining expression levels of the reporter gene for Green Fluorescent Protein (GFP). Preliminary GFP expression (transient) was detected in early transgenic roots during T-DNA transfer. Transgenic roots that developed green callus, growing on shoot-inducing medium containing 50 μg/ml Kanamycin and 100 μg/ml Timentin, were further tested for GFP expression. After several weeks of stringent selection on Kanamycin medium, several independent transgenic Arabidopsis lines were engineered and tested for GFP expression. Expression was seen both with the Super Ubiquitin promoter including intron and the Super Ubiquitin promoter without the intron. However, preliminary results indicated that the levels of expression obtained with the Super Ubiquitin intron-less promoter construct were significantly higher than those seen with the promoter including intron, suggesting that the intron may contain a repressor. The sequence of the intron is provided in SEQ ID NO: 21. EXAMPLE 2 Isolation of a CDC Promoter from Pinus radiata Plant polynucleotide sequences homologous to the Cell Division Control (CDC) protein gene were isolated from a Pinus radiata cDNA expression library as described in Example 1. Using the "Genome Walker" protocol described above and gene specific primers designed from these plant polynucleotide sequences, 5'UTR sequence containing the putative promoter of the P. radiata CDC gene was isolated from genomic DNA. The determined nucleotide sequence is given in SEQ ID NO: 4. EXAMPLE 3 Isolation of a Xylogenesis-Specific Promoter from Pinus radiata Plant polynucleotide sequences specific for plant xylogenesis were isolated from Pinus radiata cDNA expression libraries prepared from xylem, essentially as described in Example 1. Using the' "Genome Walker" protocol described above and gene specific primers designed from these plant polynucleotide sequences, sequences containing putative Pinus radiata xylogenesis-specific promoters were isolated from genomic DNA. The determined nucleotide sequences are provided in SEQ ID NO: 5 and 41-44. An extended cDNA sequence for the clone of SEQ ID NO: 41-44 is provided in SEQ ID NO: 92. EXAMPLE 4 Isolation of a 4-Coumarate-CoA Ligase Promoter from Pinus radiata Plant polynucleotide sequences homologous to the 4-Coumarate-CoA Ligase (4CL) gene were isolated from a Pinus radiata cDNA expression library as described in Example 1. Using the "Genome Walker" protocol described above and gene specific primers designed from these plant polynucleotide sequences, sequences containing the putative promoter of the P. radiata 4CL gene was isolated from genomic DNA. The determined nucleotide sequence is given in SEQ ID NO: 6. Genetic constructs comprising the reporter gene for Green Fluorescent Protein (GFP) or GUS reporter genes operably linked to the promoter of SEQ ED NO: 6 were prepared and used to transform Arabidopsis thaliana plants. EXAMPLE 5 Isolation of a Cellulose Synthase Promoter from Eucalyptus grandis Plant polynucleotide sequences homologous to the cellulose synthase gene were isolated from a Eucalyptus grandis cDNA expression library essentially as described in Example 1. Using the "Genome Walker" protocol described above and gene specific primers designed from these plant polynucleotide sequences, 5'UTR sequences containing the putative promoter of the E. grandis cellulose synthase gene were isolated from genomic DNA. Independent PCR experiments using different DNA bands as templates yielded two sequences which contained a number of base differences. One band was 750 bp in length and the nucleotide sequence of this band is given in SEQ ID NO: 7. The other band was 3 kb in length. The sequence of the 3' end of this band corresponded to the sequence given in SEQ ED NO: 7, with a number of base pair differences. The sequence of this 3' end is given in SEQ ED NO: 8.

EXAMPLE 9 Isolation of an EF1 -alpha Promoter from Eucalyptus Grandis Plant polynucleotide sequences homologous to the Eucalyptus Elongation Factor- alpha (EFl-alpha) gene were isolated from a Eucalyptus grandis cDNA expression library and used to screen a Eucalyptus grandis genomic DNA library as follows. The Eucalyptus grandis genomic DNA library was constructed using genomic DNA extracted from Eucalyptus nitens x grandis plant tissue, according to the protocol of Doyle and Doyle, Focus 12:13-15, 1990, with minor modifications. Specifically, plant tissue was ground under liquid nitrogen and dissolved in 2X CTAB extraction buffer (2% CTAB, hexadecyltrimethylammonium bromide; 1.4 M NaCl, 20 mM EDTA pH 8.0, 100 mM Tris.HCl. pH 8.0, 1% polyvinylpyrollidone). After extraction with chloroform: isoamylalcohol (24:1), 10% CTAB was added to the aqueous layer and the chloroformtisoarnylalcohol extraction repeated. . Genomic DNA was precipitated with isopropanol. The resulting DNA was digested with restriction endonuclease S κ3Al following standard procedures, extracted once with phenol:chloroform:isoamylalcohol (25:24:1) and ethanol precipitated. The digested fragments were separated on a sucrose density gradient using ultracentrifugation. Fractions containing fragments of 9-23 kb were pooled and ethanol precipitated. The resulting fragments were cloned into the lambda DASH UJBamHI vector (Stratagene, La lolla, CA) following the manufacturer's protocol and packaged using a Gigapac II Packaging Extract (Stratagene). The library was amplified once. The library was screened with radiolabeled EST fragments isolated from a Eucalyptus grandis library (as described in Example 1), that showed homology to the Eucalyptus EFl- alpha gene. Phage lysates were prepared from positive plaques and genomic DNA was extracted. From this genomic DNA, the 5'UTR region containing the putative promoter of the Eucalyptus EFl-alpha gene was obtained using the ELONGASE Amplification System (Gibco BRL). A 10 kb fragment was amplified and restriction mapped. The putative promoter region of the Eucalyptus elongation factor A (EFl-alpha) gene was identified on a 41cb fragment, which was subcloned into a pUC19 vector (Gibco BRL) containing an engineered iVotl-site.

An extended cDNA sequence for the clone of SEQ ED NO: 97 is provided in SEQ ED NO: 114. EXAMPLE 15 Polynucleotide and Amino Acid Analysis The determined cDNA sequences described above were compared to and aligned with known sequences in the EMBL database (as updated to October 2000). Specifically, the polynucleotides identified in SEQ ID NOS: 22-62 and 88-120 were compared to polynucleotides in the EMBLdatabase using the BLASTN algorithm Version 2.0.6 [Sept-16- 1998] and the polynucleotides identified in SEQ ID NOS: 121-127 were compared to polynucleotides in the EMBL database using the BLASTN algorithm Version 2.0.11 [Ian-20- 2000] set to the following running parameters: Unix running command: blastall -p blastn -d embldb -e 10 -GO -E0 -rl -v30 -b30 -i queryseq -o results. Multiple alignments of redundant sequences were used to build up reliable consensus sequences. Based on similarity to known sequences from other plant or non-plant species, the isolated polynucleotides of the present invention identified as SEQ ED NOS: 22-62 and 88-127 were putatively identified as having the functions shown in Table 1 , above. The cDNA sequences of SEQ ED NO: 1-22, 23, 25-42, 45-49, 57-59, 62, 88-99, 101- 112 and 114-127 were determined to have less than 40% identity to sequences in the EMBL database using the computer algorithm BLASTN, as described above. The cDNA sequences of SEQ ID NO: 56 and 113 were determined to have less than 60% identity to sequences in the EMBL database using BLASTN, as described above. The cDNA sequences of SEQ ED NO: 43, 52, 60 and 61 were determined to have less than 75% identity to sequences in the EMBL database using BLASTN, as described above. The cDNA sequences of SEQ ID NO: 24, 51 and 100 were determined to have less than 90% identity to sequences in the EMBL database using BLASTN, as described above. EXAMPLE 16 Modification of a Reporter Gene under Control of the Superubiquitin Promoter Six independent Arabidopsis thaliana transgenic lines were transformed with Pinus radiata superubiquitin promoter constructs to demonstrate the relative expression of a GUS reporter gene under control of different superubiquitin promoter constructs. The reporter constructs in the plasmid pBI-101 contained the GUS (β-D-glucuronidase) reporter gene in frame with the superubiquitin promoter with the intron (SEQ ID NO: 2), the superubiquitin promoter without the intron (SEQ ID NO: 3), and the CaMV 35S promoter. A reporter gene construct without a promoter sequence was used as control. Groups of six Arabidopsis thaliana plants were transformed with the reporter constructs described above, using Agrobacterium tumefaciens transformation protocols. A. tumefaciens was transformed with 100 ng of the plasmid DNA according to standard techniques, as described, for example, by Bevan (Nucleic Acids Res. 12:8711-8721, 1984). Fresh plant material was collected from each plant, protein extracted from the whole plant, and the protein concentration determined (Bradford, Anal. Biochem. 72:248-254, 1976). The protein samples were diluted with carrier bovine serum albumin to 100 ng protein to maintain readings on the fluorimeter in the linear part of the standard curve using 4-methyl- umbelliferone (MU). GUS activity was quantified by fluorimetric analysis, using a Victor 2 1420 multi-label counter (Wallac, Turku, Finland) as described by Jefferson (Plant Mol. Biol. Rep. 5:387-405, 1987). As shown in Fig. 1, the construct containing the superubiquitin promoter without the intron showed seven times more GUS activity than the CaMV 35S promoter and the construct containing the superubiquitin promoter with the intron showed sixty two times more GUS activity than the CaMV 35S promoter. No activity was detected for the promoter-less control construct. EXAMPLE 17 Determination of the Activity of Superubiquitin Promoter Constructs in Tobacco Plant Protoplasts Isolation of protoplasts Protoplasts were isolated from sterile tobacco (Nicotiana tabacum) leaf tissue and transformed with superubiquitin promoter constructs. Mesophyll protoplasts were prepared according to the method of Bilang et al, Plant Molecular Biology Manual A 1-16, 1994. A number of fully expanded leaves were removed from sterile wild type tobacco plants, sliced perpendicular to the midrib and submerged in a digestion enzyme solution containing 1.2% cellulase and 0.4% pectinase (Sigma, St. Louis MO). The leaves were left to incubate in the dark without agitation at 26°C for approximately 18.hours. The leaf strips were then gently agitated for 30 min to release the protoplasts. Protoplasts were further purified by filtration through 100 μm nylon mesh. One ml of W5 solution (154 mM MgCl 2 , 125 mM CaCl 2 , 5 mM KCl, 5 mM glucose, pH 5.8 - 6) was carefully layered on top of the filtrate and centrifuged at 80 x g for 10 min. The live protoplast layer was removed with a wide bore pipette, washed twice with 10 ml W5 solution using centrifugation at 70 x g for 5 min, with final resuspension in 5 ml W5_ solution. Protoplasts were counted in a hemocytometer and viability was determined under the microscope after staining with 5 mg/ml fluoroscein diacetate (FDA) in 100% acetone. Transformation with promoter constructs The isolated protoplasts were transformed with plasmid DNA using a polyethylene glycol protocol. After centrifugation of the purified protoplasts at 70 x g for 5 min, they were resuspended in MMM solution (15 mM MgCl 2 , 0.1% w/v 2[N-morpholino]ethanesulfonic acid (MES), 0.5 M mannitol pH 5.8) to a density of 2 x 10 6 protoplasts/ml. Aliquots containing 5 x 10 5 protoplasts/ml in 250 μl were distributed to 15 ml tubes and mixed with 20 μg plasmid DNA. 250 μl polyethylene glycoI-4000 (40%) was gently added and incubated for 5 minutes at room temperature. Ten ml W5 solution was slowly added, the protoplasts centrifuged at 70 x g for 5 min and finally resuspended in 2 ml K3 medium (Bilang et al, Plant Molecular Biology Manual AL1-16, 1994). The transformed protoplasts were incubated in the dark at 26°C for 24 hours before protein was extracted for reporter enzyme assays using 4-methyl-umbelliferyl-glucuronide (MUG). Protein was extracted from the protoplasts using the following protocol. Transformed protoplast suspensions were centrifuged at 70 x g for 10 min, resuspended in 50 μl extraction buffer (Jefferson, Plant Mol. Biol. Rep. 5:387-405, 1987) and vigorously mixed using a vortex. The homogenate was cleared by centrifugation at 4,300 rpm for 5 min, the supernatant removed and used for protein assays (Bradford, Anal. Biochem. 72:248-254, 1976). The results shown in Fig. 2 demonstrate the promoter activity of deletion constructs of the superubiquitin promoter without the intron (SEQ ID NO: 3) and the superubiquitin promoter with the intron (SEQ ID NO: 2) in tobacco plant protoplasts transformed as described above. The deletion constructs were made in plasmid pBI-101 that contained the GUS reporter gene, using Endonuclease III (Gibco BRL, Gaithersburg, MD) according to the manufacturer's protocols. The deletion constructs contained 1,103; 753; 573; 446; 368 and 195 bp of superubiquitin promoter sequence, respectively, upstream of the TATA sequence (bp numbers 1,104-1,110 of SEQ ID NO: 2). A control construct containing no sequence upstream of the TATA sequence was also made. These results show that the construct containing the entire superubiquitin promoter with the intron had the highest MU activity in the protoplasts. In Fig 3, the tobacco protoplasts were transformed with four different promoter constructs in plasmid pBI-101 containing the GUS reporter gene. These included the superubiquitin promoter without the intron (SEQ ED NO: 3), an elongation factor lα promoter (SEQ ID NO: 99) and a 5-adenosylmethionine synthetase promoter (SEQ ID NO: 100). A promoterless control was included in the experiment, and is referred to in Fig. 3 as pBI-101. EXAMPLE 18 Determination of the Activity of P. radiata Pollen-specific Promoter and E. grandis Pollen Specific Promoter Constructs in transformed Arabidopsis thaliana cv Columbia Arabidopsis thaliana transgenic lines were transformed with A. tumefaciens containing constructs of the P. radiata pollen specific promoter (SEQ ED NO: 94) and E. grandis pollen specific promoter (SEQ ED NO: 22) to demonstrate the relative expression of a GUS reporter gene under control of these promoter constructs. The promoter sequences were cloned into plasmid pBI-101 containing a GUS reporter gene. Agrobacterium tumefaciens transformation Agrobacterium tumefaciens strain GV3101 was transformed with these constructs using electroporation. Electrocompetent A. tumefaciens cells were prepared according to the method of Walkerpeach and Velten, Plant Mol. Biol Man. BL1-19, 1994. Construct DNA (4 ng) was added to 40 μl competent A. tumefaciens GV3101 cells and electroporation was done using a BTX Electro Cell Manipulator 600 at the following settings: Mode: T 2.5kV Resistance high voltage (HV), Set Capacitance: C (not used in HV mode), Set Resistance: R R5 (129 Ohm), Set charging voltage: S 1.441cV, Desired field strength: 14.41cV/cm and Desired pulse strength: 15.0 msec. 400 μl YEP liquid media (20g/l yeast, 20 g/1 peptone and 10 g/1 sodium chloride) was added to the cuvette and left to recover for one hour at room temperature. Transformed bacteria in YEP medium were spread out on solid YEP medium containing 50 mg/1 kanamycin and 50 mg/1 rifampicin and incubated at 29°C for two days to allow colony growth. Confirmation of transformation of constructs into A. tumefaciens To confirm that the constructs have been transformed into A. tumefaciens, DNA from the A. tumefaciens colonies from the YEP plates were isolated using standard protocols and amplified using the polymerase chain reaction (PCR) with primers designed from the pBI- 101 vector sequence. The primer sequences are given in SEQ ID NOS: 128 and 129. PCR reactions were set up following standard protocols and 30 PCR cycles were done with extension temperature of 72°C. Transformation of A. thaliana with transformed A. tumefaciens The optical density of the A. tumefaciens bacterial culture was adjusted to OJ with infiltration medium (5% sucrose, 0.05% Silwett L-77 surfactant). A. thaliana cv. Columbia plants (6 punnets per construct and 10-12 plants per punnet) were pruned by removing secondary bolts. Pruned A. thaliana plants in punnets were dipped, into infiltration solution and moved back and forth for 5 seconds. Punnets were put on their side to allow excess infiltration medium to drain covered with a top tray and wrapped in plastic wrap to maintain humidity. Plants were placed in a growth room at ambient conditions for 24 hours. After this period, the top tray and plastic wrap were removed and plants were set upright until siliques formed. Seeds were harvested and sterilized with a 5% sodium hypochlorite solution to destroy any residual A. tumefaciens bacteria and fungal contamination. Under sterile conditions, 100 μl seeds from the transformed A. thaliana plants were placed into an Eppendorf tube. One ml sterile water was added and the seeds left to imbibe the water for no longer than an hour. The water was remove by centrifugation, 1 ml 70% ethanol added to the seeds and gently mixed. This step was not allowed to last longer than one minute. The ethanol was removed by centrifugation, 1 ml 5% sodium hypochlorite solution was added to the seeds and gently mixed for up to 5 min. The sodium hypochlorite solution was removed by centrifugation and the seeds washed with sterile water for 1 min. The washing step was repeated three more times with centrifugation. Seeds were finally resuspended in sterile water. 500 μl of seeds in solution were pipetted onto half-strength Murashige and Slcoog medium (MS; Gibco BRL) agar plates containing 50 mg/1 kanamycin and 250 mg/1 timentin and spread evenly with a flamed wire-loop. The Petri dishes were placed in a refrigerator for 3 days to allow the seeds to stratify. Thereafter the plates were placed in growth room and grown under lights at 22°C with a 14 hour photoperiod until germination. Putative transformant seedlings were selected as those growing on the antibiotic-containing medium, with large, healthy-looking dark green leaves and a strong root system. These transgenic plants were removed and placed into soil culture at 22°C with a 12 hour photoperiod. Staining of plant tissues Tissue were taken from the flower, leaf, stem and root of A. thaliana transformed with constructs of P. radiata unknown pollen specific promoter and E. grandis pollen specific promoter and stained histochemically to determine the expression of the GUS gene under control of the pollen specific promoters. The GUS staining protocol is described by Campisi et al, Plant J. 17:699-707, 1999. A. thaliana flower, leaf, stem and root tissue were immersed in staining solution (50 mM NaP0 pH 1.2; 0.5Ψo Triton X-100; 1 mM X Glucuronide sodium salt (Gibco BRL)) for immunochemical staining. Vacuum was applied twice for 5 min to infiltrate the tissue with the staining solution. The tissue was left in the staining solution for 2 days (with agitation) at 37° for color development and then destained in 70% ethanol for 24 hours at 37°C (with agitation). The tissues were examined for blue GUS staining using a light microscope. GUS expression was observed only in the flower buds of plants transformed with the P. radiata pollen specific promoter construct, and not in the leaf, stem or root tissue. With the E. grandis pollen specific promoter construct, Gus expression was observed in the floral buds as well as in the hydathodes of the leaves. No expression was observed in the stem or root tissues. To determine in which cell layers the GUS gene was expressed, flower buds were fixed for thin sectioning. The flower buds were fixed with formaldehyde acetic acid (FAA) in an Eppendorf tube and vacuum was applied twice for 15 min. After incubation for 2 hours at room temperature, vacuum was again applied for 15 min and the tissue left overnight at 4°C. The tissues were then dehydrated using a series of ethanol and then passed into a xylene series. Paraffin wax (Sigma) was added slowly and the tissues left for 72 hours with wax changes every 12 hours. Sections of 8 to 10 μm thickness were prepared using a microtome. The thin sections illustrated that GUS expression was restricted to the tapetum cell layer in the anther of the floral bud of A. thaliana transformed with the P. radiata construct (SEQ ED NO: 49). No staining was observed in other tissues from the floral bud. GUS expression was confined to the pollen grains within the flower bud of A. thaliana transformed with the E. grandis pollen specific promoter construct, with low levels of GUS expression in the fibrous and connective tissue of the anther. No GUS expression was observed in other organs of the floral bud. EXAMPLE 19 Determination of the Activity of an E. grandis EF1 alpha Promoter Deletion Construct in transformed Arabidopsis thaliana cv Columbia Protoplasts from Nicotiana tabacum Bright Yellow 2 (BY-2) cell suspension were transformed with a deletion construct of the E. grandis EFl-alpha promoter to determine GUS expression. Base pairs 2,174 to 3J20 of SEQ ED NO: 127 were cloned into expression vector pART9, containing the reporter gene GUS and an OCS termination sequence. Preparation of protoplasts Sterile Nicotiana tabacum Bright Yellow-2 (BY-2) suspension cultures were prepared as described in Example 17. After incubation for 3 to 5 days, 3 g of the N. tabacum BY-2 cell suspension were suspended in an enzyme solution containing 1% cellulase, 0.3% pectinase and ' 0.5% driselase in 0.4 M mannitol. These were left to digest in the dark, with agitation at 26° C, for 3-4 hours. Protoplasts were purified by filtration through a 63 μm nylon mesh. Protoplasts were centrifuged at 80x g for 5 min, washed twice . with 10 ml FMS medium (Fu uda, Murashige and Skoog medium; Hasezawa & Syono, Plant Cell Physiol. 24:127-132, 1983) and finally resuspended in 5 ml FMS medium. Protoplasts were counted in a hemocytometer and viability determined by staining with 5 mg/ml FDA (fluorescein deacetate; Sigma St Louis MI) in 100% acetone by viewing under the fluorescent microscope. Transformation of Protoplasts Protoplasts were transformed according to the protocol described by Morgan and Ow (In: Methods in Plant Molecular Biology: a laboratory course manual, pp. 1-16. P. Maliga, D.Klessig, A.R. Cashmore, W. Gruissem, and J.E.Varner, eds. Cold Spring Harbor Laboratory, CSHP, NY). Briefly, the protocol is as follows. Following the counting step, protoplasts were centrifuged at 80x g for 5 min and resuspended in lx MaMg solution (0.4 M manniotol, 15 mM MgCl 2 .6H 2 0, 0.1% 2-(/V-Morpholmo)ethane sulfonic acid (MES)) to a density of 5xl0 6 protoplasts/ml. Aliquots of 100 μl (0.5 x 10 5 protoplasts) were distributed to 15 ml tubes and washed with 5 ml lx MaMg (200g, 5 min). Pelleted protoplasts were resuspended in 500ul lx MaMg solution, and heat shocked by placing at 45°C for 5 minutes. After incubation at room temperature 5-10 minutes, the transforming DNA was added (10- 20 μg DNA + 10 μg carrier DNA). To this, 500 μl 40% PEG-3500 was gently added and incubated for 25 minutes at room temperature. 5ml W5 (154 mM NaCl, 125 mM CaCl 2 JH 2 0, 5 mM KCl, 5 mM Glucose) solution was slowly added stepwise followed by centrifugation at 200x g for 5 min. Pelleted protoplasts were resuspended in 1ml K3AM medium at approximately 0.5 x 10 protoplasts/ml. Samples were transferred to 6-well plates and incubated in the dark at 26°C for 48 hours. To extract protein, protoplasts were centrifuged at 200x g for 5 min in a microfuge, resuspended in 100 μl GUS extraction buffer (50 mM NaP0 4 pH 7.2, 10 mM EDTA pH 8, 0.01% Sarcosyl, 0.1% Triton X-100) containing β-mercaptoethanol (Jefferson et al., Plant Mol. Biol Rep. 5:387-405, 1987) and vortexed for 1 min. The homogenate was cleared by centrifugation at 5,000 rpm for 5 minutes. The supernatant containing the protein was transferred to a fresh rube and stored at -80°C. The protein concentrations were determined by BioRad protein assay kit (BioRad, Hercules, CA) following the manufacturer's protocols. Protein extracts were diluted 1/10 with extraction buffer. Determination of GUS expression GUS expression in the protoplast extracts was determined using a MUG (4-methyl umbelUferyl β-D-glucuronide) assay. Protein samples, containing 1 μg protein made up to a total volume of 45 μl with extraction buffer, were aliquoted onto a microtitre plate and incubated at 37°C. To each sample, 5 μl of 10 mM MUG was added so that the final concentration of MUG was 1 mM. The plate was incubated at 37°C for 30 min and terminated by adding 150 μl stop solution (0.2 M Na 2 C0 3 , pH 11.20), still keeping the plates at 37°C. Plates were read in a Victor 2 1420 Multilabel counter with excitation set at 365 nm and emission at 455 nm. The concentration of 4-me(hyl-umbelliferone (MU) was calculated against a standard curve and the GUS expression calculated. In Fig. 4, increased expression of the GUS reporter gene in N. tabacum BY-2 protoplasts transformed with an E. grandis EF1 alpha deletion construct was seen compared to the control plasmid without an insert. EXAMPLE 20 Deteπnrnation of the Effect of the 3 'UTR Super-ubiquitin (SU) Sequences on Gene Expression in Arabidopsis thaliana cv Columbia In the polynucleotide sequences given in SEQ. ID NO: 1 encoding P. radiata superubiquitin (SU) promoter and gene sequences, an 3' untranslated region (UTR) was identified (nucleotides 1,754 to 3,083). To determine the effect of this region on the expression of genes, 250 bp of the 3' UTR (nucleotides 2,755 to 3,073 from SEQ ID NO: 1) . was cloned in the sense and antisense orientation into plasmid pBI-121 containing the GUS gene under control of the 35S CaMV promoter and plasmid pBI-101 containing the GUS gene under control of the P. radiata SU promoter (including the intron) given in SEQ ID NO: 2. For controls, constructs were made that contained the SU promoter without an intron (SEQ ED NO: 3) and without the SU 3 ' UTR sequence, the SU promoter with an intron (SEQ ID NO: 2) and without the SU 3' UTR sequence as well as a construct containing the 35S CaMV promoter but not the SU 3 ' UTR sequence. A. thaliana cv Columbia were transformed with these constructs using the floral dip protocol described in Example 18. Deterrnining the level of gene expression using a MUG assay. Six A. thaliana plants were harvested by trimming off the dried tissue and then harvesting the rest of the plant, including the roots. The roots were rinsed in tap water and the samples immersed in liquid nitrogen before storing at -80°C. Six plants from each construct were ground under liquid nitrogen and approximately 100 mg transferred to a microfuge tube. Five samples from each control were included in the assay. Extraction buffer (50 mM NaP0 4 pH7J, 10 mM EDTA pH δ, 0.01% Sarcosyl, 0.1% TritonX-100) was prepared. To 32 ml of extraction buffer, 8 ml methanol and 28 μl β-mercaptoethanol was added. Of this buffer, 200 μl was added to each sample, vortexed and stored on ice. Samples were spun at 4°C at 15, 000 rpm for 15 min. The supernatant was transferred to a fresh tube and diluted with 800 μl of extraction buffer. Protein concentration was determined using the BioRad Protein Assay Kit. The expression of GUS by the four constructs was determined using a MUG assay, as follows. To 28 ml extraction buffer (as described in. Example 18), 8 ml methanol, 56 μl β- mercaptoethanol and 4 ml of 10 mg/ml bovine serum albumin (BSA) were added. To microtitre plate wells, 100 and 10 ng of protein from each construct was added as well as 25 μl extraction buffer containing BSA and 5 μl 10 mM MUG. The plate was covered in foil and incubated at 37°C for exactly 20 minutes. The reaction was terminated by adding 150 μl 0.2 M Na 2 C0 3 pH 11.2. Plates were read with a Victor 2 1420 Multilabel counter with excitation set at 365 nm and emission at 455 nm. GUS expression levels were determined against a MU standard curve. in Fig. 5, construct SR34 containing the SU 3 'UTR in the sense orientation enhanced the expression of the SU without intron promoter almost to the level of the SU promoter with the intron. In constructs SR33 and SR35 containing the 3'UTR in the antisense orientation, promoter activity was reduced to basal levels.
