## Title
Methods for recovering polypeptides from plants and portions thereof

## Abstract

This invention provides proteins, especially protein kinases and glucosidases, which are expressed under conditions of phosphate deprivation. Further provided are nucleic acids and nucleic acid constructs encoding these proteins, cells containing the nucleic acids described and transgenic photosynthetic organisms with altered phosphate-inducible enzyme activity.

## Background
Phosphorus is one of the most important nutrients for plants. It is essential for their growth and is a structural component of nucleic acids, phospholipids, intermediary metabolites and numerous other biological molecules.

In plants, the only readily absorbed form of exogenous phosphorus is inorganic phosphate (P.sub.i) (Bieleski, 1973). When the amount of available phosphate is low, plants are unable to grow vigorously and productively. When phosphate is absent, growth is halted and the plant dies.

Because they are sessile organisms, plants must deal biochemically with environmental stresses such as temperature extremes, nutrient deficiency and drought. This is also true for other photosynthetic organisms which are either sessile or limited in movement. Plants and other photosynthetic organisms, therefore, require signal transduction pathways in order to trigger cellular responses to adverse environmental stimuli.

It has long been known that both temporal and quantitative characteristics of flowering are affected by the level of phosphate in plants relative to the level of nitrogen (Salisbury and Ross, 1985). Relatively high phosphate advances maturity in plants, whereas relatively low phosphate results in little or no flowering taking place. Phosphate levels are also known to affect the biomass ratio between root and shoot. Specifically, phosphate deprivation causes preferential growth of roots (Lefebvre et al., 1982). Thus, in many environments, the availability of phosphorus becomes a major factor limiting the growth and reproduction of photosynthetic organisms.

Numerous groups have investigated the nature of the phosphate-starvation response in plants but despite these studies, little is known of the molecular mechanisms that regulate phosphorus uptake and metabolism. In general, plants exhibit significant morphological and physiological changes in response to perturbations within the environment.

There have been many attempts to identify proteins which are induced under conditions of phosphate starvation. Fife et al. (1990) have conducted in vivo protein labeling studies in Brassica nigra cells grown in suspension in either rich or low phosphate medium. Using 2-dimensional gel electrophoresis, they demonstrated the novel synthesis of four proteins under P.sub.i deficiency and one protein in well-nourished cells. Other groups have reported that P.sub.i deprivation increases the synthesis of a plasma membrane protein and a soluble protein in tomato root cultures (Hawkesford and Belcher, 1991), and enhances secretion of six proteins from tomato suspension cells (Goldstein et al., 1989). It has also been shown that a gene for a protein homologous to .beta.-glucosidases is induced to high levels in B. nigra suspension cells under P.sub.i starvation (Malboobi and Lefebvre, 1995).

As part of the adenosine nucleotides, ADP and ATP, which are the currency of cellular energy, phosphorus is critical to bioenergetics. Further, the covalent addition or removal of a phosphate group to or from a biological substrate (phosphorylation and dephosphorylation, respectively) often functions as a kind of regulatory "on/off switch" in cellular metabolism and signal transduction. For example, the phosphorylation and dephosphorylation of certain membrane-bound receptor protein kinases and their substrates are key to various signal transduction pathways, including pathways of plant hormones such as ethylene (Kieber et al., 1993) and abscisic acid (Anderberg and Walker-Simmons, 1992). Self-incompatiblity with respect to pollination and fertilization also involves the activity of protein kinases encoded by S-locus genes (Tantikanjana et al., 1993; Zhang and Walker, 1993).

Knowledge of the proteins which affect the uptake and accumulation of phosphorus and which are expressed in phosphate-deficient environments is essential to understand phosphate metabolism and to manipulate the growth and reproduction of photosynthetic organisms for commercial or industrial purposes. Further, the identification and synthesis of the genes which encode such proteins would allow the development of transgenic photosynthetic organisms for many purposes.

This invention provides the means to modify phosphorus metabolism in plants and other photosynthetic organisms by altering the expression and/or activity of one or more proteins involved in the response of plants or other photosynthetic organisms to phosphorus deprivation. This invention further provides means for more efficient metabolic utilization of phosphorus by plants and other photosynthetic organisms. The compounds of this invention provide the means to change plant morphology by altering phosphorus metabolism. In some applications, the modification will be restricted to seeds, where it can lower the amount of phytate, an anti-nutritive phosphorus storage compound.

This invention relates to isolated DNA (genes) encoding proteins involved in phosphorus uptake and metabolism of plants and other photosynthetic organisms inducible by phosphate deficiency (psr proteins), as well as DNA complementary to these genes, and recombinant DNA constructs and vectors containing DNA encoding such proteins or such complementary DNA, in whole or portions thereof.

In particular, the present invention provides DNA (genes) encoding protein kinases and .beta.-glucosidases of Arabidopsis thaliana and Brassica nigra, whose transcription is inducible by phosphate starvation, and further provides the RNA so transcribed. The nucleic acids (both DNA and RNA) of this invention encode proteins which differ from other protein kinases in having a unique portion of their amino acid sequence which is different from any other known protein kinase. The .beta.-glucosidases of this invention differ from other known .beta.-glucosidases in sequence and because their level of expression is specifically dependent on phosphate deprivation.

Other nucleic acids of the invention include nucleic acids with sequences complementary to the nucleic acid sequences of Arabidopsis thaliana and Brassica nigra, or portions thereof; nucleic acids with sequences related to, but distinct from, the nucleic acid sequences of Arabidopsis thaliana and Brassica nigra and inducible under conditions of phosphate deficiency; and nucleic acid sequences that differ from the nucleic acid sequences of Arabidopsis thaliana and Brassica nigra, such as modified analogues, due to alteration of the sequence through mutation, substitution, deletion and the like. Primers and probes consisting of 20 or more contiguous nucleotides of the above-described nucleic acids are also included as part of this invention. Homologues and other proteins which are similar in function and are psr proteins are also encompassed by this invention.

Thus, one type of nucleic acid of the invention is an antisense oligonucleotide, a triple helix-forming oligonucleotide, or other oligonucleotide that can be used to inhibit the activity of the psr proteins encoded by the nucleic acids described herein. Such oligonucleotides can block the expression or activity of any of these proteins in a number of ways; for example, preventing transcription of a psr protein-encoding gene by triple helix formation, or by binding to the mRNA transcribed by the gene in any manner that prevents a functional protein from being assembled. Typically, and depending on the mode of action, the oligonucleotides of the invention comprise a specific sequence of about 20 to about 200 or more nucleotides which are identical or complementary to a specific sequence of nucleotides of the psr protein-encoding gene or transcribed mRNA.

The invention further provides nucleic acids of the invention operatively linked to a regulatory sequence, and plasmids or recombinant expression vectors for producing the nucleic acids encompassed by this invention. In a preferred embodiment, a recombinant expression vector, comprising the nucleic acids operatively linked to a regulatory sequence is adapted for transformation of a plant cell.

The invention also provides transgenic cells expressing one or more of the psr proteins of the invention. In a preferred embodiment, the transgenic cells are plant cells. The invention includes transgenic plants produced with nucleic acids or vectors of the invention which express psr proteins provided by the invention. The invention further includes transgenic plant parts, including seeds, as well as tissue culture or protoplasts produced with nucleic acids or vectors of the invention.

The invention also provides a recombinant expression vector adapted for transformation of a plant cell, comprising a DNA molecule operatively linked to a regulatory sequence to allow expression of an RNA molecule that is antisense to a nucleic acid sequence having substantial sequence homology with the nucleotide sequence of SEQ ID NO:1, SEQ ID NO:3, SEQ ID NO:5, SEQ ID NO:7, or SEQ ID NO:9.

The invention further provides a method of preparing a psr protein having psr protein activity using the nucleic acids of the invention. The method comprises culturing a transformant or transgenic cell including a recombinant expression vector comprising a nucleic acid of the invention and a regulatory sequence operatively linked to the nucleic acid in a suitable medium until the psr protein is expressed, and then isolating the psr protein. The invention also provides an isolated psr protein or polypeptide having psr protein activity and substantial sequence homology with either or both of the amino acid sequences shown in SEQ ID NO:2, SEQ ID NO:4, SEQ ID NO:6, SEQ ID NO:8, SEQ ID NO:10, or a portion thereof.

Antibodies and antibody fragments which bind to the novel psr proteins described herein (or to portions of these sequences) are also included in this invention. In a preferred embodiment, the antibody is a monoclonal antibody.

The invention further provides a method for reducing expression of a psr protein of a photosynthetic organism, preferably a plant, comprising the step of incorporating into the organism an isolated nucleic acid which is antisense to a nucleic acid having substantial sequence homology with the nucleotide sequence of a gene encoding a psr protein, especially SEQ ID NO:1, SEQ ID NO:3, SEQ ID NO:5, SEQ ID NO:7, or SEQ ID NO:9.

The methods of this invention can also be used to override dominant alleles thereby producing lowered expression rates or, at an extreme, the "null allele" phenotype. This occurs when a partial or complete complementary sequence to an mRNA is present in the cell. It is generally assumed that, in the presence of antisense RNA, mRNA:antisense hybrids are produced with the result that a substantial reduction in detectable levels of the target gene product is observed. The antisense transcripts can cause a reduction in steady-state sense mRNA levels, perhaps because of increased turnover, or specific duplex attack by double-stranded RNases (Murray and Crockett (1992). The construction of antisense genes must take into consideration that expression levels have to be sufficiently high and be temporally coincident with target gene expression. In addition, in order to avoid the possibility of affecting gene expression at loci of distinct functions, sequence specificity must be assured. This can be achieved by selecting fragments of the nucleic acid sequences encoding psr proteins from translated or from untranslated regions.

The invention further provides a method for reducing expression of a psr protein of a plant, comprising the step of incorporating into a plant, an isolated nucleic acid which causes co-suppression of genes which are identical to or which have substantial sequence homology to the nucleic acid sequences of psr proteins.

The invention further provides a method for lowering or increasing the activity of a par protein of a plant, comprising the step of incorporating into the plant an isolated nucleic acid which causes the production of an altered par protein such that it is either more active, or is dysfunctional and interferes with the native (naturally-occurring) functional psr protein in any way that its activity is reduced.

Thus, this invention provides means for regulating the response of a photosynthetic organism to varying levels of phosphate in its environment as well as a mechanism for modifying the phosphate metabolism of such organisms. This approach to modifying the phosphate pathways of plants has several advantages over traditional plant breeding methods, most importantly, the modifications can be made quickly and specific traits can be modified, even introducing a new trait which is not part of the plant genome.

The present invention provides novel methods for producing photosynthetic organisms, especially plants, the organisms so produced and methods of their use. This invention is based, in part, on the discovery that the transcription and expression of several proteins are induced in phosphate-starved cells of photosynthetic organisms. Thus, this invention provides isolated DNA encoding at least a functional portion of a protein (psr protein) of a photosynthetic organism in which transcription of the DNA is induced by phosphate deficiency. In particular, the genes encoding two classes of psr proteins, ser/thr (serine/threonine) protein kinases and .beta.-glucosidases have been isolated and sequenced. As shown in the figures, all nucleic acids which encode psr polypeptides, and homologues of these psr nucleic acids, are encompassed by this invention.

Isolation of clones

As an initial step in the investigation of the P.sub.i -starvation response of B. nigra suspension cells, in vitro translations of mRNA extracted from P.sub.i -starved and P.sub.i -fed cells were compared to investigate if alterations in protein synthesis profiles of B. nigra cells might be controlled at the transcriptional level. First, B. nigra suspension cells were grown in medium containing 1.25 mM P.sub.i for 7 days, so that all cells would be in the same metabolic state. The cells were then subcultured into media with various initial concentrations of P.sub.i. Growth conditions for the next 7 days were either severe P.sub.i -deprivation (0 P.sub.i), mild P.sub.i deprivation (1.25 mM P.sub.i) or rich (10 mM P.sub.i) (Lefebvre et al.,1990). In mild P.sub.i deprivation, the plant cells absorbed all the P.sub.i by day 2, whereas in the rich conditions, the cells did not take up all the P.sub.i even after 7 days in culture. Total mRNA was isolated from each culture and these isolates were subjected to in vitro translation. The resultant polypeptides were separated on a high resolution SDS-PAGE gel.

Phosphate starvation did not cause gross changes in the protein synthesis profiles of B. nigra (Fife et al., 1990). However, by comparison with the 10 mM P.sub.i -fed cells, the inventors consistently isolated lower amounts of RNA from the minus P.sub.i -treated cells, indicating a possible decrease in the rate of protein synthesis. This agrees with the high content of free amino acids observed in these cells (Duff et al., 1994).

Scanning densitometry of the SDS-PAGE gel identified four polypeptides (approx. 31.7, 32.3, 52.5, and 64.8 kDa) present only in the P.sub.i -starved samples (see FIG. 2). These results agree with those of the in vivo protein synthesis analysis of B. nigra suspension cells reported by Fife, et al. (1990). Using 2-dimensional gel electrophoresis, they showed the novel synthesis of four proteins (64 kDa, pI 5.2; 41 kDa, pI 5.6; 27 kDa, pI 5.7; 27 kDa, pI 5.2) under P.sub.i deficiency and one protein (33 kDa, pI 5.1) in well-nourished cells. Acknowledging that such comparisons are at best speculative since post-translational modifications can only be made in living cells, the inducible proteins reported by Fife et al. possess similar sizes to those detected in this study.

A cDNA library was constructed from mRNA isolated from the severely deprived B. nigra cells. Screening by differential hybridization was performed on this CDNA library using cDNA probes prepared from minus P.sub.i -treated and 10 mM P.sub.i -fed (well-fed) B. nigra cells. A number of clones representing mRNA species preferentially transcribed under P.sub.i -deficiency were identified. These phosphate-starvation responsive (psr) clones (121 clones) were placed into eleven different homology groups as determined by cross-hybridization. Northern blots showed that the expression of each of the eleven distinct groups of genes is controlled at the level of transcription (Malboobi and Lefebrve, 1995). The Northern blots showed that corresponding genes are inducible in both mild and severe P.sub.i -starvation conditions; that is, possible side effects of extremely stressful conditions leading to cell death on the induction of these genes can be ruled out.

As shown in FIG. 3, the expression of certain genes (grey bars) was also induced in the 7-day old 1.25 mM P.sub.i -fed cells that had undergone mild P.sub.i deprivation. The corresponding-protein sizes are approximately 31.7, 32.3, 52.5 and 64.8 Kd. If in vitro transcription rates are independent of message type, then the levels of de novo expression of four of the differentially expressed messages in minus P.sub.i -treated cells were relatively high, comparable to those of the most abundant mRNAs in these cells. Based on expression patterns, the proteins encoded by these genes play active metabolic and structural roles in cellular adaptation to P.sub.i stress.

Identification and Characterization of Phosphate-inducible genes: Protein Kinase psr genes

DNA sequencing and subsequent analysis permitted the identification of one of the genes, psrPK (psr1), as a protein kinase (SEQ ID NO:3) whose expression is induced in phosphate-starved Brassica nigra cells. A homologue (SEQ ID NO:1) which is also differentially expressed under P.sub.i deprivation was identified and isolated from A. thaliana.

The induced Arabidopsis thaliana gene encodes a polypeptide designated psrPK (or psr1) which, along with the B. nigra polypeptide, has regions of high homology to other protein kinases (see Example 9 and FIG. 8, infra), and possesses serine/threonine (ser/thr) protein kinase activity. However, A. thaliana psrPK and its B. nigra homologue are different from previously described protein kinases because they have a unique C-terminal region of the protein kinase. This unique region could be involved in P.sub.i concentration detection or in receiving or delivering signals, or more than one of these functions. The protein kinases substrates could be other components of the phosphate-starvation response pathway or enzymes involved in the response itself. These proteins have no apparent N-terminal signal peptide, organellar targeting sequence or membrane spanning regions, which indicates they probably function in the cytoplasm of the cell.

Protein kinases catalyze phosphorylation of protein substrates and are found in all living organisms. They are known to be involved in regulatory processes, wherein phosphorylation/dephosphorylation functions as a type of switch for the activation/deactivation (or vice versa) of the substrate protein. Certain types of protein kinases are involved in the phosphate starvation response of fungi and bacteria; however, this is the first time that a plant protein kinase has been shown to be inducible to high levels under P.sub.i starvation. Because psrPK is particularly active during periods when phosphate is unavailable, it is probable that it has a switch-like role in the control of the plant response to phosphate deprivation. The psrPK protein is homologous to SNF1, which is expressed in carbon-starved bacteria and has been shown to be involved in governing metabolic reactions under such conditions. Thus, modulation of the expression of the psrPK kinase could alter the expression of whole pathways involved in phosphate metabolism, thereby producing valuable phenotypes.

Identification and Characterization of Phosphate-inducible genes: .beta.-glucosidase psr genes

One homology group (psr3) of phosphate-starvation responsive CDNA clones from Brassica nigra was determined to contain a .beta.-glucosidase based on a portion of the polypeptide sequence (Malboobi and Lefebvre, 1995). The DNA sequence (SEQ ID NO:7) encoding this phosphate starvation-induced .beta.-glucosidase (psr 3.1B) from Brassica nigra and the amino acid sequence (SEQ ID NO:8) of the full-length psr3.1B protein is shown in FIG. 15.

Southern blots of Arabidopsis thaliana genomic DNA probed with the psr3.1 CDNA indicated that this gene exists as a single locus. A genomic library of A. thaliana was screened at high stringency to isolate the corresponding genomic clone. The resultant clone was designated psr3.2 (SEQ ID NO:5) because of its sequence divergence from isolated psr3.1 cDNA clones. Northern blotting with probes derived from the coding region of the genomic clone showed that this gene is expressed at high levels in P.sub.i -starved roots and enhancement occurs within two days of growth in medium lacking P.sub.i. The expression of this gene is repressed by heat shock and anaerobic conditions, and it is not significantly induced by high salinity, or by nitrogen or sulphur deprivation. Sequence analysis of the genomic clone revealed the existence of thirteen exons interrupted by twelve AT-rich introns and shows high homology with the B. nigra psr3.1B, as well as various other .beta.-glucosidase genes from other species. Sequence similarity and divergence percentages between the deduced amino acid sequences of the psr3 clones and other .beta.-glycosidases suggests that these genes should be included along with two other Brassicaceae genes in a distinct subfamily of the BGA glycosidase gene family. The presence of an endoplasmic reticulum retention signal at the carboxy terminus indicates that this is the cellular location of psr3.2. The possible metabolic and regulatory roles of this enzyme during the P.sub.i -starvation response are described infra.

Identification and Characterization of Phosphate-inducible genes: Other Related psr genes

DNA sequencing and computer analysis for the remaining nine psr clones was performed using the techniques described in Example 8. Genomic libraries of other species were screened as described in Example 9 to identify homologues of the genes.

The DNA sequence of psr2 from Brassica nigra most closely resembles a glutamate dehydrogenase at the T3 portion of the sequence and an ovomucoid protein at the T7 portion of the sequence (FIG. 18).

The DNA sequence of psr4 from Brassica nigra most closely resembles an envelope protein (FIG. 19).

The DNA sequence of psr5 from Brassica nigra most closely resembles an aspartate kinase (FIG. 20). This sequence shows some homology to disintegrin, another aspartate kinase, which inhibits the signal transduction pathway for the cell cycle.

The DNA sequence of psr6 from Brassica nigra most closely resembles a phosphate transporter protein (FIG. 21).

The DNA sequence of psr7 from Brassica nigra most closely resembles a histidine kinase at the T3 portion of the sequence and a skeletal muscle calcium release channel protein psr7 at the T7 portion of the sequence (FIG. 22).

The DNA sequence of psr8 from Brassica nigra most closely resembles a sugar transporter protein is shown in FIG. 23.

The DNA sequence of psr9 from Brassica nigra most closely resembles an adenylate cyclase (FIG. 24).

The DNA sequence of psr10 from Brassica nigra most closely resembles a calcium channel protein (G-protein) (FIG. 25).

The DNA sequence of psr11 from Brassica nigra most closely resembles a phosphatidylinositol kinase at the T3 portion of the sequence and a tripeptidyl peptidase protein at the T7 portion of the sequence (FIG. 26).

Isolated Nucleic Acids and Constructs

This invention provides isolated DNA or recombinant nucleic acids encoding a protein, or a functional portion thereof, of a-photosynthetic organism wherein transcription (or translation) of the DNA or nucleic acid is induced by phosphate deficiency. In a preferred embodiment the protein has protein kinase activity, especially ser/thr protein kinase activity, or .beta.-glucosidase activity. The term "nucleic acid" includes DNA and RNA, as well as single-stranded and double-stranded species.

DNA or nucleic acids referred to herein as "isolated" are DNA or nucleic acids separated away from the nucleic acids of the genomic DNA or cellular RNA of their source or origin (e.g., as it exists in cells or in a mixture of nucleic acids such as a library), and may have undergone further processing. "Isolated" DNA or nucleic acids include DNA or nucleic acids obtained by methods described herein, similar methods or other suitable methods, including essentially pure DNA or nucleic acids, DNA or nucleic acids produced by chemical synthesis, by combinations of biological and chemical methods, and recombinant nucleic acids which are isolated. Nucleic acids referred to herein as "recombinant" are nucleic acids which have been produced by recombinant DNA methodology, including those nucleic acids that are generated by procedures which rely upon a method of artificial recombination, such as the polymerase chain reaction (PCR) and/or cloning into a vector using restriction enzymes. "Recombinant" nucleic acids are also those that result from recombination events that occur through the natural mechanisms of cells, but are selected for after the introduction to the cells on nucleic acids designed to allow and make probable a desired recombination event.

The isolated DNA can comprise: (a) SEQ ID NO:1, SEQ ID NO:3, or a truncated nucleic acid sequence which encodes a functional portion of the protein encoded by SEQ ID NO:1 or SEQ ID NO:3 or (b) a nucleic acid sequence having at least 80% homology to SEQ ID NO:1, SEQ ID NO:3, or a truncated nucleic acid sequence which encodes a functional portion of the protein encoded by a nucleic acid sequence having at least 80t homology to SEQ ID NO:1 or SEQ ID NO:3; or (c) a nucleic acid which is complementary and hybridizes under moderately stringent conditions to any of the sequences of (a) or (b). A "functional portion" means a portion of a psr protein which when expressed will affect the phosphate uptake and/or metabolism of the native (naturally-occurring) photosynthetic organism in which the endogenous psr protein is produced. A preferred embodiment is a truncated DNA sequence comprising isolated DNA consisting of nucleotide residues 984 to 1240 of SEQ ID NO:1, encoding the unique region of the protein kinase or a nucleic sequence encoding YLDANCE (SEQ ID NO:48). Further provided is DNA or RNA having 50% homology or which hybridizes under moderately stringent conditions to the DNA of claim 3. Truncated nucleic acid sequences of the above-described DNA or nucleic acids which consist of 10-20 or more contiguous nucleotides are also provided and can find use as probes and primers.

One cDNA of this invention is shown in FIG. 5 (SEQ ID NO:1) and comprises a 1020 nucleotide open reading frame, bounded by ATG start and TAG stop codons, encoding 339 amino acids. The cDNA further comprises 89 bp 5' untranslated nucleotides and 141 bp 3' untranslated nucleotides, including a 3' polyA tail for a functional mRNA. The protein encoded by this cDNA is discussed in detail below.

The isolated DNA of this invention further comprises: (a) SEQ ID NO:5, SEQ ID NO:7, SEQ ID NO:9, or a truncated nucleic acid sequence which encodes a functional portion of the protein encoded by SEQ ID NO:5, SEQ ID NO:7, or SEQ ID NO:9; or (b) a nucleic acid sequence having at least 80% homology to SEQ ID NO:5, SEQ ID NO:7, SEQ ID NO:9, or a truncated nucleic acid sequence which encodes a functional portion of the protein encoded by a nucleic acid sequence having at least 80% homology to SEQ ID NO:5, SEQ ID NO:7, or SEQ ID NO:9; or (c) a nucleic acid which is complementary and hybridizes under moderately stringent conditions to any of the sequences of (a) or (b). Polypeptides encoded by these nucleic acids are also encompassed by this invention. Further, an isolated nucleic acid encoding a protein having .beta.-glucosidase activity and an amino acid sequence with at least 80% sequence homology with SEQ ID NO:5 or 50% homology with SEQ ID NO:6 is also provided. Truncated nucleic acid sequences of the above-described DNA or nucleic acids which consist of 10-20 or more contiguous nucleotides are also provided and can find use as probes and primers.

For the purposes of this disclosure, the term "homology" does not refer to common evolutionary origin, but rather to similarity between sequences. The degree of homology between two sequences can be determined by optimally aligning the sequences for comparison, as is commonly known in the art, and comparing a position in the first sequence with a corresponding position in the second sequence. When the compared positions are occupied by the same nucleotide or amino acid, as the case may be, the two sequences are homologous at that position. The degree of homology between two sequences is expressed as a percentage representing the ratio of the number of matching or homologous positions in the two sequences to the total number of positions compared.

The term "having substantial sequence homology" is understood to mean that the sequence in question has slight or insignificant sequence variations from, for example, the sequences of SEQ ID NO:1, SEQ ID NO:3, SEQ ID NO:2 or SEQ ID NO:4. That is, a nucleic acid sequence "having substantial sequence homology" to SEQ ID NO:1 or SEQ ID NO:3 encodes substantially the same protein product as the actual sequence; i.e., a protein kinase having a regulatory function in phosphate metabolism. It is expected that certain substitutions or other alterations will be able to be made in various portions of SEQ ID NO:1 or SEQ ID NO:3 which do not significantly affect protein function. The sequence variations may derive from mutation. Further, a protein having a homologous sequence to that of SEQ ID NO:2 or SEQ ID NO:4 would have a similar catalytic activity to that of the protein whose sequence is shown in SEQ ID NO:2 or SEQ ID NO:4. Alternatively, isoforms of the protein of SEQ ID NO:2 or SEQ ID NO:4 that have protein kinase activity could exist. For example, a sequence having substantial homology to that of SEQ ID NO:2 can be a homologue from another plant variety or species, as is SEQ ID NO:4. Such isoforms and homologous proteins may be immunologically cross-reactive.

It is expected that a nucleic acid encoding a protein comprising an amino acid sequence having about 80% homology with the amino acid sequence of SEQ ID NO:2 or SEQ ID NO:4, or about 50% homology with the amino acid residues 190 to 340 of SEQ ID NO:2, will produce a functional protein kinase, and the invention provides such a nucleic acid. Proteins comprising an amino acid sequence that is about 60%, 70%, 80% or 90% homologous with the amino acid sequence of SEQ ID NO:2 or SEQ ID NO:4, or greater, are also expected to have protein kinase activity.

The invention encompasses isolated nucleic acids encoding a protein having protein kinase activity, and having a sequence that differs from the nucleotide sequence of SEQ ID NO:1 or SEQ ID NO:3 due to degeneracy in the genetic code. "Degeneracy" is understood to mean that each of several different amino acids is designated by more than one nucleotide triplet or codon. For example, AAA and AAG each code for lysine. This is an example of a "silent mutation" occurring in the third (or "wobble") nucleotide of a codon wherein the amino acid encoded remains the same.

The invention also encompasses mutations that are not silent or other alterations wherein at least 80% amino acid homology with SEQ ID NO:2 or SEQ ID NO:4, or at least 50% homology with amino acid residues 190 to 340 of SEQ ID NO:2, is maintained.

It would be understood by a person skilled in the art that the invention includes different forms of the nucleic acids of the invention arising from alternative splicing of an mRNA corresponding to a cDNA of the invention.

The invention further provides a nucleic acid that hybridizes under high or moderate stringency conditions to a nucleic acid encoding at least a portion of the amino acid sequence shown in SEQ ID NO:2 or SEQ ID NO:4. Stringency conditions for hybridization is a term of art which refers to the conditions of temperature and buffer concentration which permit hybridization of a particular nucleic acid to another nucleic acid in which the first nucleic acid may be perfectly complementary to the second, or the first and second may share some degree of complementarity which is less than perfect. See, sections 2 and 6 in Current Protocols in Molecular Biology (Ausubel, F. M. et al., eds., Vol. 1, Supplement 29, 1995). Hybridization conditions are described generally in Maniatis et al., 1982 and Sambrook et al., 1989.

High stringency hybridization procedures, for example, can (1) employ low ionic strength and high temperature for washing, such as 0.015 M NaCL/0.0015 M sodium citrate, pH 7.0 (0.1.times. SSC) with 0.1% sodium dodecyl sulfate (SDS) at 50.degree. C.; (2) employ during hybridization, 50% (vol/vol) formamide with 5.times. Denhardt's solution (0.1% weight/volume highly purified bovine serum albumin/0.1% wt/vol Ficoll/0.1% wt/vol polyvinylpyrrolidone), 50 mM sodium phosphate buffer at pH 6.5 and 5.times. SSC at 42.degree. C.; or (3) employ hybridization with 50% formamide, 5.times. SSC, 50 mM sodium phosphate (pH 6.8), 0.1% sodium pyrophosphate, 5.times.Denhardt's solution, sonicated salmon sperm DNA (50 .mu.g/ml), 0.1% SDS, and 10% dextran sulfate at 42.degree. C., with washes at 42.degree. C. in 0.2.times. SSC and 0.1% SDS.

By varying hybridization conditions from a level of stringency at which no hybridization occurs to a level at which hybridization is first observed, conditions which will allow a given sequence to hybridize with the most similar sequences in the sample can be determined.

This invention also provides nucleic acids and polypeptides with structures that have been altered by different means, including but not limited to, alterations using transposons, site-specific and random mutagenesis, and engineered nucleotide substitution, deletion, or addition.

Proteins

This invention also relates to psr proteins or psr polypeptides, for example the proteins encoded by SEQ ID NO:1, SEQ ID NO:3, SEQ ID NO:5, SEQ ID NO:7, SEQ ID NO:9, or homologous nucleic acids. As shown in the figures, all psr polypeptides and homologues are encompassed by this invention.

The proteins and polypeptides of the present invention can be isolated and/or recombinant. Proteins or polypeptides referred to herein as "isolated" are proteins or polypeptides purified to a state beyond the naturally-occurring state in which they exist endogenously in cells. A preferred embodiment is an essentially pure protein or polypeptide free of other proteins or polypeptides. "Isolated" proteins or polypeptides include proteins or polypeptides obtained by methods described herein, similar methods or other suitable methods, including essentially pure proteins or polypeptides, proteins or polypeptides produced by chemical synthesis, or by combinations of biological and chemical methods, and recombinant proteins or polypeptides which are isolated. Proteins or polypeptides referred to herein as "recombinant" are proteins or polypeptides produced by the expression of recombinant nucleic acids.

The transcription of these proteins is induced under conditions of phosphate deficiency and the proteins have protein kinase activity. Preferably, the amino acid sequence of these proteins shows at least 80% sequence homology with SEQ ID NO:2, SEQ ID NO:4, SEQ ID NO:6, or 50% homology with amino acid residues 190 to 340 of SEQ ID NO:2.

Isolation of Homologues

Nucleic acids or portions thereof provided by this invention can be used to isolate homologous nucleic acids from cells of other species of photosynthetic organisms which contain genes encoding one or more psr proteins similar in function to the nucleic acids of this invention. The term "psr protein" means a protein whose expression is induced to higher levels under conditions of phosphate deficiency than under conditions of phosphate sufficiency. The protein may not be expressed at all if the cell has adequate levels of available phosphate. Further such a protein is not associated with mechanisms which bring about cell death.

As described in the examples below, the inventors have isolated nucleic acids of the invention using B. nigra suspension cells as starting material. In brief, the inventors created a cDNA library from B. nigra suspension cells that had been starved for phosphate for seven days. The library was screened using two sets of cDNA probes generated from B. nigra suspension cells that had been grown under conditions of no phosphate or 5 mM phosphate, respectively. Clones that hybridized strongly to the first set of probes, but not the second set, were isolated. The cDNA inserts of these clones were subjected to dideoxy nucleotide sequencing (Sanger, 1981) to determine nucleotide sequence, and amino acid sequence was predicted therefrom. The psrPK gene was recognized to encode a novel protein kinase. Other differential hybridization, cloning and sequencing methods are known to those skilled in the art, and can be employed to obtain the protein kinase genes isolated by the inventors or homologues thereof.

Alternatively, a nucleic acid of the invention can be isolated in the following manner. A nucleic acid probe comprising at least a portion of the sequence of SEQ ID NO:1 or a homologue is chemically synthesized or prepared using recombinant DNA techniques. The probe is radiolabelled and used to screen a cDNA or genomic DNA library according to standard techniques. It can be prepared from B. nigra, a different organism or another source having a homologue or transgene of the invention that could be identified under appropriate hybridization conditions. The DNA identified by screening the library is then cloned and sequenced using standard techniques.

A third alternative method for isolating a nucleic acid of the invention is to isolate or chemically synthesize a peptide of the protein kinase and use this peptide to produce an antibody to the protein kinase in an animal. The antibody is then used according to standard techniques to screen a cDNA library, from B. nigra or another source, for immunoreactive clones. DNA from such clones are then sequenced as is known in the art.

A fourth alternative method for isolating a nucleic acid of the invention is to selectively amplify such a nucleic acid using polymerase chain reaction (PCR) (Saiki et al., 1985; Konat et al., 1991) and DNA or RNA as a template. In the latter case, total mRNA may be isolated from cells using one of the methods common in the art, described in Maniatis et al., 1982. The retroviral enzyme reverse transcriptase is then used to synthesize cDNA complementary to the mRNA. Appropriate oligonucleotide primers for the amplification of the chosen nucleic acid are designed and synthesized, and PCR performed on a mixture of the primers and cDNA using standard technology (Innis et al., 1990). The PCR protocol can additionally include 5' or 3' RACE (rapid amplification of cDNA ends) methodology (Innis et al., 1990). The amplified DNA fragment produced is cloned into an appropriate vector.

An RNA molecule of the invention can also be constructed by cloning an appropriate cDNA or an amplified DNA molecule as described above into one of the commonly available transcription vectors. The DNA would usually be cloned downstream of a promoter, for example, the SP6 promoter of the vector PGEM 3Z (Promega, Madison, Wis.), the appropriate RNA polymerase (in this example, SP6 polymerase) added, and transcription reactions performed according to the manufacturer's specifications. Other useful promoters carried by commonly used transcription vectors are the bacteriophage T7 and T3 promoters.

Another well-known method of producing a nucleic acid or oligonucleotide of the invention is chemical synthesis. Various machines for DNA synthesis are well-known in the art, such as, for example, those sold by Applied Biosystems, Inc. of Foster City, Calif. and by Millipore Corp. of Bedford, Mass. and can be used for such syntheses.

Alteration of Protein Expression with Recombinant Expression Vectors

Alteration of psrPK expression can be achieved in a variety of ways. In one embodiment, recombinant nucleic acids are constructed in which psrPK is operatively linked to regulatory sequences, such as promoters, that control the level, timing or tissue-specificity of gene expression.

Standard recombinant DNA techniques can be employed to engineer a recombinant expression vector including a nucleic acid of the invention that allows expression of at least a portion of a protein kinase of the invention. See, e.g., Sambrook, et al., 1989. The engineered vector would also include a regulatory sequence "operatively linked" to the nucleic acid of the invention to allow such expression. For the purposes of this disclosure, the term "regulatory sequence" includes promoters, enhancers and other sequences that control expression or message stability, as are well-known in the art. Examples of known promoters suitable for these purposes are given infra. Those of skill in the art can recognize that these examples are not limiting and other promoters can be adapted for particular purposes of modulating the phosphate uptake and metabolism of photosynthetic organisms.

In some cases, the regulatory element can provide tissue-specific expression. The two-part term "operatively linked" means both that the regulatory sequence contains sufficient element(s) to allow expression of the nucleic acid in question and that the nucleic acid is linked to the regulatory sequence appropriately. For example, the nucleic acid of the invention is in the appropriate orientation and in phase with an initiation codon.

In the context of this disclosure, the term "promoter" or "promoter region" refers to a sequence of DNA, usually upstream (5') to the coding sequence of a structural gene, which controls the expression of the coding region by providing recognition and binding sites for RNA polymerase and/or other factors required for transcription to start at the correct site.

There are generally two types of promoters, constitutive and inducible promoters. The term "constitutive" as used herein does not necessarily indicate that a gene is expressed at the same level in all cell types, but that the gene is expressed in a wide range of cell types, although some variation in abundance is often detected.

An inducible promoter is a promoter that is capable of directly or indirectly activating transcription of one or more DNA sequences or genes in response to an inducer. In the absence of an inducer the DNA sequences or genes will not be transcribed. Typically a protein factor (or factors), that binds specifically to an inducible promoter to activate transcription, is present in an inactive form which is then directly or indirectly converted to an active form by the inducer. The inducer can be a chemical agent such as a protein, metabolite, growth regulator, herbicide or phenolic compound, or a physiological stress imposed directly by heat, cold, salt, or toxic elements or indirectly through the action of a pathogen or disease agent such as a virus. The inducer can also be an illumination agent such as light, darkness and light's various aspects which include wavelength, intensity, fluence, direction and duration. A cell containing an inducible promoter may be exposed to an inducer by externally applying the inducer to the cell or plant such as by spraying, watering, heating or similar methods. If it is desirable to activate the expression of a gene at a particular time during plant development, the inducer can be so applied at that time.

Examples of such inducible promoters include heat shock promoters, such as the inducible hsp70heat shock promoter of Drosphilia melanogaster (Freeling, et al., 1985; a cold inducible promoter, such as the cold inducible promoter from B. napus (White, et al., 1994,); and the alcohol dehydrogenase promoter which is induced by ethanol (Nagao, et al., 1986).

Among sequences known to be useful in providing for constitutive gene expression are regulatory regions associated with Agrobacterium genes, such as nopaline synthase (Nos), mannopine synthase (Mas) or octopine synthase (Ocs), as well as regions regulating the expression of viral genes such as the 35S and 19S regions of cauliflower mosaic virus (CaMV) (Brisson, et al. 1984), or the coat promoter of TMV (Takamatsu, et al., 1987).

Other useful plant promoters include promoters which are highly expressed in phloem and vascular tissue of plants such as the glutamine synthase promoter (Edwards, et al., 1990) the maize sucrose synthetase 1 promoter (Yang et al., 1990), the promoter from the Rol-C gene of the TLDNA of Ri plasmid (Sagaya, et al., 1989), and the phloem-specific specific region of the pRVC-S-3A promoter (Aoyagi, et al., 1988). Alternatively, plant promoters such as the small subunit of Rubisco (Rbcs) promoter (Coruzzi, et al., 1984; Broglie, et al., 1984), or heat shock promoters, e.g., soybean HPS17.5-E or HPS17.3-B (Gurley, et al., 1986) can be used.

Other promoters which can be used according to the present invention include, but are not limited to: (Wang et al., 1995; Wang and Cutler, 1995) and the ABA inducible promoter from EM gene wheat (Marcotte Jr. et al., 1989). from Arabidopsis (Martin et al., 1993); et al., 1993); (Unger et al., 1993) the psi lectin promoter from pea (de Pater et al., 1993), the phaseolin promoter from Phaseolus vulgaris (Frisch et al., 1995); 1993); (Cordes et al., 1989); (Kosugi et al., 1995); al., 1995); (Hattori et al., 1995); and tuber parenchyma cells, such as the ADP GP from potato (Muller-Rober et al., 1994); barley (Wissenbach et al., 1993); and promoter from Arabidopsis (Vorst et al., 1993).

Depending on the type of regulatory sequence employed, a plant transformed with a recombinant nucleic acid of this invention would over- or under-express a psr protein, either in chosen plant parts or throughout the plant, and/or at different times in the life history of the plant. Changes in plant size, relative sizes of different plant parts, time of flowering, level of phytate, starch and oil accumulated in seeds, or other phenotypic characteristics can thus be engineered.

Numerous recombinant expression vectors are known that are suitable for expression in a variety of cell types. A recombinant expression vector can be engineered for expression of a psr protein, such as psrPK, in prokaryotic cells, for example, Escherichia coli, or in eukaryotic cells, for example, Saccharomyces cerevisiae (yeast) and Arabidopsis thaliana, tobacco or canola. The recombinant expression vector can be a plasmid, a bacteriophage or a virus. Plant gene constructs of the present invention can be introduced using Ti plasmids, Ri plasmids, plant virus vectors, direct DNA transformation, microinjection, electroporation, and the like, as described, supra. Common expression vectors often include a marker gene that permits easy screening for transformed cells. Some common vectors also include a sequence encoding at least a portion of another functional protein, such as firefly luciferase or bacterial .beta.-galactosidase. In a scheme employing this kind of vector, a nucleic acid of the invention would be linked in frame to this coding sequence such that a fusion protein would be produced comprising at least a portion of the protein kinase of the invention and the other functional protein. Cells transformed with the engineered vector could be screened for expression of the luciferase, .beta.-galactosidase or other fused protein. Alternatively, the other protein fused to the protein kinase may not be useful for screening, but can instead provide a useful property such as increased solubility, or can be exploited in a protein purification scheme or in industrial applications such as the addition of purified enzyme to a reaction.

Accordingly, the inventors vectors can be constructed containing nucleic acids encoding a psr protein with which to transform a wide variety of crop and horticultural plants, including monocots, dicots and gymnosperms. Modification can be targeted to the whole plant, or a specific tissue, organ or plant part, such as a seed. Further, expression of the gene can be limited to particular developmental stages or environmental conditions. The gene delivery systems used to incorporate the constructs will vary depending on the target plant species; however, those of skill in the art can recognize that present molecular techniques can be applied to successfully modify particularly useful crop plants, such as rice, wheat-, barley, rye, corn, soybeans, canola, sunflower, potato, carrots, sweet potato, beans, peas, lettuce, cabbage, cauliflower, broccoli, turnip, radish, spinach, onion, garlic, pepper, carrots, pumpkins, cucumber, apples, pears, melons, plum, cherry, peaches, nectarines, apricot, strawberry, grape, raspberry, pineapple, tobacco, bananas, sorghum, sugarcane, and the like.

For example, several plant species, canola, tobacco and Arabidopsis, have been genetically engineered to include vectors designed both to lower and to increase the amount of protein kinase within the entire plant or in the developing seeds.

In one embodiment, eight different constructs were incorporated into Arabidopsis cells with either constitutive (CaMV 35S) or seed-specific (Arabin) promoters. These constructs are described in Table 1 below. ______________________________________ A. thaliana sense/ Construct Promoter protein kinase antisense ______________________________________ 1         Constitutive complete gene sense sequence 2 Seed-specific complete gene sense sequence 3 Constitutive complete gene antisense sequence 4 Seed-specific complete gene antisense sequence 5 Constitutive truncated gene sense sequence 6 Seed-specific truncated gene sense sequence 7 Constitutive truncated gene antisense sequence 8 Seed-specific truncated gene antisense sequence ______________________________________

The first four of these constructs containing complete gene sequence are depicted in FIGS. 12A-12D.

Transformant Cells

The invention provides host cells transformed with a recombinant expression vector of the invention. For the purposes of this disclosure, the terms "transformed with", "transformant", "transformation", "transfect with", "transformant" and "transfection" all refer to the introduction of a nucleic acid into a cell by one of the numerous methods known to persons skilled in the art. Transformationof prokaryotic cells, for example, is commonly achieved by treating the cells with calcium chloride so as to render them "competent" to take up exogenous DNA, and then mixing such DNA with the competent cells. Prokaryotic cells can also be infected with a recombinant bacteriophage vector.

Nucleic acids can be introduced into cells of higher organisms by viral infection, bacteria-mediated transfer (e.g., Agrobacterium T-DNA delivery system), electroporation, calcium phosphate co-precipitation, microinjection, lipofection, bombardment with nucleic-acid coated particles or other techniques, depending on the particular cell type. For grasses such as corn and sorghum, microprojectile bombardment as described, for example, in Sanford, J. C., et al., U.S. Pat. No. 5,100,792 (1992) can be used. Other useful protocols for the transformation of plant cells are provided in Gelvin et al., 1992. Suitable protocols for transforming and transfecting cells are also found in Sambrook et al., 1989. The nucleic acid constructs of this invention can also be incorporated into specific plant parts such as those described infra through the transformation and transfection techniques described herein.

To aid in identification of transformed plant cells, the constructs of this invention are further manipulated to include genes coding for plant selectable markers. Useful selectable markers include enzymes which provide for resistance to an antibiotic such as gentamycin, hygromycin, kanamycin, or the like. In the constructs of FIGS. 12A-12D, the NOS/NPTII kanamycin-resistant gene is used to detect transfected plant cells. Similarly, enzymes providing for production of a compound identifiable by colour change such as GUS (.beta.-glucuronidase), or by luminescence, such as luciferase, are useful.

The invention provides transformant cells in which the introduced DNA has integrated into the genome, and transformant cells in which the introduced DNA exists as an extrachromosomal element. In the latter case, maintenance of an extrachromosomal element can be easily obtained by including a selectable marker in the recombinant expression vector and then, after introduction of the vector, growing the cells under conditions where expression of the marker gene is required. In one embodiment of this invention, cells transformed with a recombinant expression vector of the invention are screened using protein kinase activity as a selectable marker. Such transformed cells can be screened, for example, under conditions of phosphate starvation.

Plants and other photosynthetic organisms containing the nucleic acid constructs described herein are provided by this invention. The term "photosynthetic organism" is meant to include the members of the kingdom Planta, including vascular and nonvascular plants (angiosperms, gymnosperms, ferns, mosses, bryophytes, etc.), the algae, photosynthetic protists (single-celled eukaryotes), the Cyanophyta (blue-green algae or cyanobacteria) and the photosynthetic bacteria. Suitable plants include both monocotyledons and dicotyledons. Examples of preferred monocotyledons are commercially-important crop plants such as rice, corn, wheat, rye, sugarcane and sorghum. Examples of preferred dicotyledons are canola, sunflower, tomato, broccoli, and lettuce. Algae can be used as a hosts for the constructs described herein. Examples of such algae are Chlamydomonas reinhardtii, Chlamydomonas moewusii, Euglena gracilis, Porphyra purpurea, Cryptomonas sp., and Ochromonas sinensis. Prokaryotes can also provide suitable host cells. Specific examples include Anacystis nidulans, Synechococcus sp., Rhodobacter sphaeroides, Rhodobacter capsulatus, Chloroflexus aurantiacus, and Heliobacterium chlorum.

The constructs of the present invention can be introduced into plants, plant parts, or other cells of photosynthetic organisms using Ti plasmids, Ri plasmids, plant virus vectors, direct DNA transformation, micro-injection, electroporation, etc. For reviews of such techniques see, for example, Weissbach and Weissbach, (1988) and Grierson and Corey, Plant Molecular Biology, 2d Ed., Blackie, London, Ch. 7-9 (1988).

The method of obtaining transformed cells and/or regenerated plants is not critical to this invention. In general, transformed plant cells are cultured in an appropriate medium, which can contain selective agents such as antibiotics, where selectable markers are used to facilitate identification of transformed plant cells. Selected transformed plant cells can be induced to form callus tissue. Once callus forms, shoot formation can be encouraged by employing the appropriate plant hormones in accordance with known methods and the shoots transferred to rooting medium for regeneration of plants.

The transformants or descendants of transgenic plants so produced can be evaluated with respect to growth and productivity. Transgenic plants can also be assessed for flowering characteristics, root and shoot size ratios, and seed phytate, starch and oil content. The transformants would be used directly or could be subjected to further modifications by genetic engineering or classical techniques.

Transgenic plants containing the constructs of this invention can also be regenerated from plant tissues, plant parts, or protoplasts by methods known to those of skill in the art. Plant part is meant to include any portion of a plant capable of producing a regenerated plant. Thus, this invention encompasses cells, tissue (especially meristematic and/or embryonic tissue), protoplasts, epicotyls, hypocotyls, cotyledons, cotyledonary nodes, pollen, ovules, stems, roots, leaves, and the like. Plants can also be regenerated from explants. Methods will vary according to the plant species.

Seed can be obtained from the regenerated plant or from a cross between the regenerated plant and a suitable plant of the same species. Alternatively, the plant can be vegetatively propagated by culturing plant parts under conditions suitable for the regeneration of such plant parts. The plants can then be used to establish repetitive generations containing an altered genotype with respect to phosphate-inducible protein kinase activity, either from seeds or using vegetative propagation techniques.

Homology-dependent gene silencing including antisense nucleic acids

The invention further encompasses homology-dependent gene silencing including silencing for the nucleic acid of the invention mediated by DNA--DNA pairing and by RNA. In the former, DNA interaction between an introduced nucleic acid or oligonucleotide and the native homologue(s) result in co-suppression of the genes. RNA-mediated silencing includes antisense technologies in which a nucleic acid or oligonucleotide that is antisense to a nucleic acid of the invention is introduced into cells. Such an antisense molecule is capable of base-pairing (hydrogen bonding) with the nucleic acid of the invention in an anti-parallel manner, according to the standard pair rules, i.e., G pairs with C, and A pairs with T or U. The antisense molecule can be complementary to a coding or non-coding region of a nucleic acid of the invention, including a non-coding regulatory region, or to portions of both (Gogarten et al., 1992; Shotkoski and Fallon, 1994). The region of complementarity can precede or span the first codon of SEQ ID NO:1. An antisense molecule according to the invention can include a region complementary to a regulatory sequence, for example a non-coding regulatory sequence that is operatively linked to a gene of the invention in an expression construct. Alternatively, catalytic antisense RNA directed at the protein kinase gene transcript (a ribozyme) can be employed to reduce gene expression (Heinrich et al., 1993; de Feyter et al., 1996). The antisense molecule can be produced by chemical synthesis, PCR or an expression vector, using certain of the techniques discussed in the previous section, or by other standard techniques. (Meyer, P. and Saedler, H., 1996).

Antisense constructs include, but may not be limited to, the following: 930 through 1272) of FIG. 7; (nucleotides 930 through 1080) which includes the partially conserved nucleic acid sequence encoding the EEEXXD sequence; (from nucleotide 1073) which includes the codon for the conserved "D" residue at position 336 of the amino acid sequence of FIG. 8; the polyA tail (nucleotides 1008-1240); or (nucleotides 10 through 88).

If cell death occurs with an antisense construct under the control of a seed specific or constitutive promoter, an inducible promoter could be used. Sense or antisense nucleic acid according to the invention can be delivered to cells using any of a variety of methods known to persons skilled in the art.

Isolated Proteins

This invention provides an isolated protein having protein kinase, .beta.-glucosidase, or other psr protein activity and, in particular, an amino acid sequence with substantial sequence homology with the amino acid sequence shown as SEQ ID NO:2, SEQ ID NO:4, SEQ ID NO:6, SEQ ID NO:8, or SEQ ID NO:10. Alternatively, an isolated protein of the invention can be encoded by a nucleic acid that hybridizes under low or high stringency conditions to the nucleotide sequence of SEQ ID NO:1, SEQ ID NO:3, SEQ ID NO:5, SEQ ID NO:7, SEQ ID NO:9, or a protein encoded by any psr gene. It should be understood that the invention includes protein fragments demonstrating such homology and having psr protein activity (i.e., functional portions).

The mature, unmodified protein having the amino acid sequence shown as SEQ ID NO:2 is predicted to have a molecular weight of 39,040 kDa. Prosite searches were used to determine the following characteristics of the PSRPK protein. It contains ser/thr protein kinase active site between amino acid positions 119-131, and an ATP-binding site between positions 9-33. An hydrophobicity plot of the protein does not indicate any long regions of membrane associated protein and antigenicity plot of the protein indicates several areas that would be appropriate for employment as peptides for antibody production against the protein. These include but are not restricted to the last 150 amino acids at the C-terminus. As there are no apparent N-terminal signal peptides or organellar targeting sequences, the protein appears to be cytoplasmically localized. There are a number of potential phosphorylation sites which include, but may not be restricted to, positions that are indicated by motifs for PKC, CK2, and tyrosine kinase phosphorylation sites as shown in FIG. 9. These may or may not be autophosphorylation sites. There is a putative glycosylation site in the C-terminal region.

A psr protein of the invention can be purified from cells or from culture medium into which it has been secreted. Alternatively, it can be chemically synthesized, as is well-known in the art. As discussed above, for the purposes of this disclosure, the term "isolated" means that the protein is substantially free of other cellular material or culture medium when produced by recombinant DNA techniques, or chemical precursors or other chemicals when produced by chemical synthesis.

The invention further provides a method of preparing a protein having protein kinase activity, .beta.-glucosidase activity, or other psr protein activity, or a fragment of such a protein, which includes the following steps: (i) transforming cells with a recombinant expression vector including a nucleic acid of the invention and a regulatory sequence operatively linked to the nucleic acid, (ii) culturing the transformant cells in a suitable medium until the psr protein is formed, and (iii) isolating the psr protein. A person skilled in the art would be able to devise a scheme for the isolation of the protein from other cellular material and culture medium using conventional techniques (Scopes, 1982). These include chromatographic methods such as gel filtration, ion-exchange chromatography and affinity chromatography, as well as batch methods employing ion-exchange or affinity resins. Precipitation with ammonium sulfate, followed by resuspension and dialysis is another common purification and concentration protocol.

In another embodiment of the invention, a fusion protein comprising at least a functional portion of the psr protein of the invention can be prepared by the method whose steps are detailed above. In some embodiments, the psr protein or functional portion thereof can be fused to a signal sequence which directs secretion of the fusion protein from the transformant cells. The secreted protein can be isolated using standard techniques.

Antibodies

The invention encompasses an antibody that is specific for a psr protein of this invention. The invention includes both polyclonal and monoclonal antibodies. For purposes of this disclosure, the term "antibody" includes antibody fragments that are specific for a psr protein, such as a protein kinase or .beta.-glucosidase, described herein. Such fragments include F.sub.ab fragments generated by proteolysis of an antibody. In some embodiments, an antibody can be directed to an epitope unique to the psr protein of the invention. If the protein is a protein kinase of this invention, for example, these can include the protein kinase active site and the ATP-binding site as well as the unique C-terminus sequence of 41 amino acids.

Intact psr proteins or an immunogenic fragment thereof can be used to prepare antibodies. The protein or fragment chosen as the antigen can be injected into an animal (e.g., rabbit, hamster, goat, mouse), causing the animal to produce antibodies specific to the injected antigen. The antigen is often combined with an adjuvant, such as Freund's adjuvant. In some cases, prior to injection, the antigen is conjugated to a hapten, or carrier molecule. A person skilled in the art would be aware of appropriate antigen dosages for the size and species of animal, how to design a schedule of repeated injections if required, and how to titer and purify the antibody raised in the animal's serum. Methods of preparing antibodies including these and other aspects are described in Harlow and Lane, 1988.

For the production of monoclonal antibodies, lymphocytes raised against the antigen are first harvested, and then fused with myeloma cells using standard procedures (Harlow and Lane, 1988). The immortalized hybridoma cells so produced are screened for protein kinase-specific antibodies using conventional immunoassay methods such as ELISA (enzyme-linked immunosorbent assay). The antibodies can then be purified as is known in the art.

An antibody of the invention can be physically coupled to any of a number of detectable substances that are known in the art. These include: a radioisotope, a fluorescent molecule, and an enzyme capable of catalyzing a calorimetric reaction. Examples of such an enzyme include alkaline phosphatase and horseradish peroxidase, which are commonly used in laboratory assays.

Thus, this invention provides a method of detecting the expression of a phosphate-starvation inducible protein, such as a protein kinase or a .beta.-glucosidase, in a plant or plant part or other photosynthetic organism comprising: (a) inducing the protein expression by depriving the plant, plant part, or other photosynthetic organism of sufficient levels of available phosphorus; (b) contacting a portion of a plant, plant part, or other photosynthetic organism with antibody to the protein so that an antibody:antigen complex is formed by the binding of the antibody to an epitope of the protein; and (c) detecting the antibody:antigen complex; wherein the detection of the antibody:antigen complex is indicative of the expression of the protein.

Transgenic Plants and Photosynthetic Organisms

The classical approach to optimizing plant characteristics utilizes traditional plant breeding methods 30 wherein plants with desirable traits are crossed to produce new, true-breeding cultivars carrying the traits. This approach has at least two serious drawbacks. First, traditional plant breeding relies on the availability of desired traits within known cultivars. The desired phosphate-related traits discussed supra are either not part of the genome of certain species or varieties or cannot be acquired to the required level of expression in plants wherein they occur. Second, traditional breeding is a relatively slow process.

A more modern approach to modifying the characteristics of plants (and other photosynthetic organisms) is to subject plants to mutagenesis by radiation or chemical treatment. Such exposure randomly generates mutations in the DNA molecules comprising the plant genome which sometimes produces the desired traits. The mutagenized plants are screened for the traits and subsequently bred. While mutagenesis has the advantage of producing variations in plant DNA much faster than natural selection, it is not possible to select and generate preferred traits; the process is random. Further, exposing plants to mutagenic agents can induce additional, undesirable mutations to the plant genome. Some of these may not be immediately apparent and, further, may not be able to be "bred out" of a plant carrying a useful mutation.

The nucleic acids and vectors of the invention can also be used to produce transgenic plants and other photosynthetic organisms which express the protein of the invention. The genome of a transgenic organism includes an integrated DNA transgene that was introduced either into that particular organism or into its ancestor. The introduced DNA including the transgene can comprise regulatory element(s) appropriate for the type of organism or tissue being transfected. For example, when introduced as a transgene, a nucleic acid of the invention can be operatively linked to a tissue-specific DNA regulatory sequence such that protein kinase is specifically produced in the target tissue. A seed-specific promoter would permit expression of the protein kinase only in seeds. Also, a suitable 3' region such as the 3' region containing a polyadenylation signal of Agrobacterium tumor inducing (Ti) plasmid genes can be included. Or other suitable 3' sequences derived from any characterized gene from plants as well as from other organisms such as animals, if they are deemed appropriately functional in the environment of a transgenic plant cell, can be used. To aid in identification of transformed plant cells, the constructs of this invention can be further manipulated to include genes coding for plant selectable markers.

Thus, genetic engineering provides a method of producing a transgenic plant or other photosyntheic organism having altered growth, reproduction, or metabolic content by introducing into a cell or tissue of a plant or other photosynthetic organism, an exogenous nucleic acid which encodes a .beta.-glucosidase which is transcribed under conditions of phosphate deprivation in naturally-occurring species in which it occurs, and whose presence in the transgenic plant or photosynthetic organism results in altered growth, reproduction, or metabolic content, and by maintaining the cell or tissue containing the exogenous nucleic acid under conditions appropriate for growth of the cell or tissue, whereby a transgenic plant or other photosynthetic organism having an altered growth, reproduction, or metabolic content can be produced. More specifically, the nucleic acids comprising the psrPK, psr3.2, psr3. 1A, psr3. 1B genes and homologues can be used in this method to produce a transgenic plant from a species which belongs to the vascular plants including angiosperms, gymnosperms, monocots, and dicotsand the algae are plants, and the algae. Thus plants and other photosynthetic organisms are provided wherein the naturally-occurring phosphate-starvation induced protein kinase or .beta.-glucosidase activity is reduced. Because the introduced gene is stably integrated into the genome, seed of a transgenic plant and, therefore future generations of descendants, with this alteration, are also provided by this invention.

Applications and Utilities

Photosynthetic organisms have evolved a number of adaptive strategies to cope with growth-limiting amounts of exogenous inorganic phosphate. These strategies include enhancing the availability of endogenous phosphate (Lefebvre et al., 1990; Sachay et al., 1991), and using it efficiently in order to maintain essential metabolic pathways (Duff et al., 1994), as well as, in times of plenty, storing excess phosphate in vacuoles (Lee et al., 1990; Mimura et al., 1990; Tu et al., 1990) so that it can later be used to replenish the cytoplasmic pool as required (Rebeille et al., 1983). Also, root systems secrete acids and phosphatases that increase phosphate availability by releasing P.sub.i from rock phosphate and phosphate esters, respectively (Lefebvre et al., 1990; Sachay et al., 1991). The mechanisms of these relief strategies involve changes in either protein synthesis and degradation (Duff et al., 1991), or secretion of pre-existing proteins, including phosphatases (Goldstein, 1992). They invoke changes in phosphate-dependent reactions of photosynthesis (Rao et al., 1990; Usuda and Shimogawara, 1993), respiration (Duff et al., 1989b; Duff et al., 1994; Hoefnagel et al., 1993; Nagano and Ashihara, 1993; Rychter and Mikulska, 1990; Theodorou and Plaxton, 1993), nucleotide synthesis (Ashihara et al., 1988; Rychter et al., 1992), protein synthesis (Sadka et al.,1994) and synthesis of cell wall and other metabolites (Fife et al., 1990).

The physiological consequences of P.sub.i limitation in the Brassica nigra (B. nigra) cell culture system have been studied extensively. These include the accumulation of lipids, starch and phenolic compounds (Fife et al., 1990), an elevated potential for P.sub.i absorption (Lefebvre et al., 1990) and the apparent deployment of alternative enzymes that act to "bypass" P.sub.i - or nucleotide-dependent reactions (Duff et al., 1989b; Duff et al., 1994; Theodorou and Plaxton, 1993).

Recently, in an effort to define components of the regulation of homeostasis of P.sub.i concentration in plant cells, a mutant of Arabidopsis thaliana, pho2, was isolated that accumulates excess P.sub.i in the shoot (Delhaize and Randall, 1995). The authors suggested that this mutation could affect the regulation of P.sub.i transport across cell membranes. Another mutant, pho1, of this species identified previously is defective in loading of P.sub.i into xylem (Poirier et al., 1991).

It has been proposed that ribonucleases and phosphatases act in tandem to cleave and dephosphorylate RNA molecules in a P.sub.i recycling process (Goldstein, 1992). One extracellular (Glund and Goldstein, 1993; Nurnberger et al., 1990) and four intracellular ribonucleases were reported to be induced in P.sub.i -starved tomato (Loffler et al., 1992). The activities of phosphatase enzymes are known to increase in plants experiencing P.sub.i deficiency (Duff et al., 1989a; Duff et al., 1991; Duff et al., 1994; Goldstein et al., 1989) and it has been shown that acid phosphatases are synthesized de novo in P.sub.i -starved cell cultures of B. nigra (Duff et al., 1989b). The synthesis of the a-subunit of PP.sub.i -dependent phosphofructokinase is also induced in B. nigra cells under P.sub.i stress (Theodorou et al., 1992). Recently, high concentrations of P.sub.i have been shown to down-regulate a sucrose-inducible phosphatase gene (vspB) in soybean (Sadka et al., 1994).

A P.sub.i -starvation inducible .beta.-glucosidase could be involved in the deglycosylation and, hence regulation of, certain enzymes during P.sub.i stress (Balou and Fisher, 1986; Gellatly et al., 1994).

The nucleic acids, constructs, and methods of this invention can be applied to regulate aspects of the phosphate-starvation response of photosynthetic organisms, as well as phosphate metabolism of such organisms in general. By altering the activity of a psr protein, i.e., changing the level of expression or modifying its activity, a change in regulation of the phosphate metabolism pathways can be effected. Thus, phosphate metabolism efficiency could be improved, allowing growth of organisms in phosphate-poor soils without addition of phosphate fertilizers, or improved growth even in phosphate-sufficient environments. Reducing the amount of phosphate fertilizer required for crop plants and/or improvement in yields, would have significant and desirable economic and environmental ramifications.

Also, the timing of certain plant phenomena that depend on phosphate metabolism can be altered. For example, the temporal and quantitative aspects of flowering can be modified in photosynthetic organisms in which reproductive evocation is responsive to the ratio of nitrogen to phosphorus in their environments. Earlier flowering would shorten the growing season for crops and reduce the seed to flowering time for bedding plants. Conversely, delay in flowering is desirable in crops harvested for their biomass, such as lettuce and spinach.

Alteration of phosphate metabolism of plants can also result in an altered biomass ratio between root and shoot, and be used to produce a commercial benefit in root crops, such as carrots. Additionally, the ability to induce larger root systems on plants early in the growing season would contribute to drought tolerance later during drier months.

Further, photosynthetic organisms can be modified to increase the nutritive value of vegetative or reproductive organs. For example, seed plants such as canola, soybean and corn, store phosphate in the form of phytate (the salt of 1, 2, 3, 4, 5, 6-cyclohexanehexolphosphoric acid). The presence of phytate is a problem where the seed is made into meal and used as feed for animals. Monogastric animals cannot metabolize phytate and utilize its phosphate. In addition, phytate binds to essential minerals, such as calcium, manganese and zinc, making them relatively unavailable to the animal. Alteration of phosphate metabolic pathways in plants could be altered to reduce the level of phytate in seeds in favour of a phosphate storage form that is more usable for animals and humans.

The advantages of the compounds and methods of this invention are multifold and those of skill in the art will recognize that the examples given above are just a few of the applications provided by this invention.

Increased Expression of Protein Kinase

The following examples indicate what can occur if psrPK is over expressed or modified to increase its activity. Part of this invention is also to implement the opposite strategy in which this gene or its homologues are underexpressed or modified to decrease activity. Those of skill in the art will recognize that similar techniques can be used to alter the expression of other psr proteins.

General constitutive promoters can be employed to increase expression of psrPK and similar genes throughout the transformed organism to increase its ability to utilize phosphate, thereby growing better under conditions of phosphate limitation and imparting the ability of the plant or other organism to grow better under any regime of phosphate nutrition.

Tissue-specific expression in the roots can have the effect of increasing root size as well as increasing the root's ability to acquire phosphate from the environment and to use it more efficiently in their root metabolism.

Shoot-specific expression is anticipated to alter the temporal aspects and magnitude of flowering, as well as increasing the efficiency phosphate utilization in the shoot.

Seed-specific expression can alter the efficiency of phosphate utilization in the seed thereby causing more seeds to set and larger seeds to be formed. This strategy can also reduce phytate storage pools in the seed. This can also increase the starch and oil storage capacity of the seed. Phosphate-deprived B. nigra suspension cells store more fixed carbon than phosphate-sufficient cells (Lefebvre et al. 1990).

Other tissue-specific expression can include root hairs for increased phosphate uptake, and other tissues where excessive or inadequate expression can be deleterious to cells and can cause cell death. This can be employed in the production of male sterile lines for hybridization purposes, among other applications.

Methods of Reducing Protein Kinase Expression

The invention encompasses methods of reducing expression of a nucleic acid or a protein of the invention. For example, a transgenic organism can be produced which expresses a molecule that binds directly to an endogenous psrPK protein and reduces its protein kinase activity or its ability to bind a substrate or cofactor. Further, expression of a molecule which binds to a cis-acting regulatory element or a trans-acting regulatory factor so as to interfere with their function can decrease protein kinase expression.

A third method can employ the modification of a nucleic acid or a protein such that it is dysfunctional and interferes with the native (naturally-occurring) functional protein in any way so that its protein kinase activity is reduced or eliminated.

A fourth method can employ an antisense molecule as described in section II above. The inventors contemplate that, when an antisense molecule of the invention is delivered to target plant cells, it will hydrogen bond with endogenous nucleic acid molecules encoding the protein kinase, thereby reducing gene expression of the protein kinase. The antisense molecule can be designed such that its region of complementarity with an endogenous protein kinase-encoding nucleic acid molecule includes the initiation codon of the sense strand. The antisense molecule can include regions complementary to coding or noncoding regions of the sense strand, or both.

A fifth method can employ transformation such that the introduced nucleic acid comprising part or all of the nucleic acid of the invention in the sense orientation reduces protein kinases expression by any means including gene co-suppression (Meyer and Saedler, 1996).

Although this invention is described in detail with reference to preferred embodiments thereof, these embodiments are offered to illustrate but not to limit the invention. It is possible to make other embodiments that employ the principles of the invention and that fall within its spirit and scope as defined by the claims appended hereto.

Plant Cell Culture

Non-photosynthetic, rapidly growing Brassica nigra cell suspensions were cultured as described (Lefebvre et al., 1990) in MS medium (Murashige and Skoog, 1962) containing 6% sucrose (17.5 mM), and 2 mg/l 2,4-dichlorophenoxyacetic acid (2,4-D) at 24.degree. C. with 130 r.p.m. rotary shaking. To assure the same nutritional state for all cultured cells, 6 ml of 7-day old cultures containing 3 ml of cells (packed cell volume) were inoculated into 44 ml of fresh MS medium containing 1.25 mM P.sub.i. Packed cell volume was determined by allowing the cells to settle from the culture medium in sterile graduated cylinders for 45 min. After 7 days of culture, the same quantity of cells was subcultured into 44 ml of fresh MS medium containing either 10 mM, 1.25 mM, or no phosphate and incubated for an additional 7 days. For the 10 mM P.sub.i treatments, filter-sterilized KH.sub.2 PO.sub.4 adjusted to pH 5.8 with KOH was added to the 1.25 mM P.sub.i medium. In the minus P.sub.i treatments, an equal molarity of KCl replaced the KH.sub.2 PO.sub.4.

The patterns of growth and endogenous phosphate concentrations of these cultured cells are shown in FIG. 1. Cells fed with 10 mM P.sub.i had ample supplies of this nutrient for the duration of the culture period. Cells fed with 1.25 mM P.sub.i, in comparison to minus P.sub.i -treated cells, underwent only mild P.sub.i deprivation by relying on conversion of their own internal phosphate. Quantitative determination of endogenous phosphate was performed as previously described (Lefebvre et al., 1990).

After 7 days growth, the cultured cells were collected on fritted glass filters with 10 .mu.m pore size, and rinsed with 100 ml of 0.5 mM CaCl.sub.2 before freezing in liquid nitrogen and storage at-70.degree. C. until required.

Extraction of Total RNA and mRNA

Total RNA from the harvested B. nigra cells of Example 1 was isolated as described by Chirgwin (Chirgwin et al., 1979). The cells were homogenized at ice-cold temperature using a homogenization buffer containing 4 M guanidinium isothiocyanate (GIBCO/BRL, Burlington, Canada). Poly(A).sup.+ RNA (mRNA) was purified by using the mRNA purification kit and recommended protocol of Pharmacia (Uppsala, Sweden and Piscataway, N.J.). Total RNA and mRNA isolated from minus P.sub.i -treated, 1.25 mM P.sub.i -fed and 10 mM P.sub.i -fed cells were quantified spectrophotometrically and examined on formaldehyde/agarose gels (Sambrook et al., 1989).

Analysis of Changes in the Populations of mRNA Species Using in Vitro Translation

It is well known that the protein synthesis profiles of P.sub.i -starved and P.sub.i -fed B. nigra cells differ. Such differences in response to P.sub.i starvation could be mediated in various ways. To investigate whether any alterations in protein levels are due to changes at the transcriptional level, in vitro translations of mRNA extracted from P.sub.i -starved and P.sub.i -fed B. nigra cells were compared. In vitro translation of mRNA purified as above was carried out according to the protocol of Promega (Madison, Wis.), using wheat germ extract (Promega) and [.sup.35 S]-methionine (ICN, Costa Mesa, Calif.) diluted with unlabeled methionine to a final concentration of 0.5 mCi/ml.

After translation, a 5 .mu.l aliquot was removed from each reaction mixture and combined with 20 .mu.l of gel-loading buffer to a final concentration of 1% SDS (Laemmli, 1970). The samples were placed in a boiling water bath for 5 min and then subjected to denaturing SDS-polyacrylamide gel electrophoresis (SDS-PAGE) using an LKB 2010 Macrophor electrophoresis apparatus (Pharmacia Biotech, Inc., Baie d'Urfe, Canada) and the discontinuous system of Laemmli (Laemmli, 1970). Molecular weight standards electrophoresed in parallel were .sup.14 C-labeled .alpha.-lactalbumin, carbonic anhydrase, glyceraldehde-3-phosphate dehydrogenase, chicken egg albumin and bovine serum albumin having molecular weights of 14, 29, 36, 45 and 66 kDa, respectively (Sigma, St. Louis, Mo.). The gels were 0.4 mm thick slabs containing 1% SDS. The acrylamide monomer concentrations were 5% (w/v) for the stacking gel and 10% for the separating gel. The separating gel was 35 cm long, to maximize resolution of protein species. Electrophoresis was performed at 25.degree. C. for 5 h at a constant current of 30 mA.

Upon completion of electrophoresis, the gel, bound to a bind-silane-treated (Pharmacia) glass plate, was incubated in 600 ml of fixing solution containing 20% trichloroacetic acid (TCA) and 10% methanol for 20 The gel was then washed three times in 600 ml of post-fixing wash solution containing 10% ethanol and 5% acetic acid, and dried to the glass plate overnight in a fume hood at room temperature. The dried gel was exposed to X-ray film using a Cronex intensifying screen (DuPont, Wilmington, Del.) at -70.degree. C. and the film was developed using Kodak developer and fixer solutions. The autoradiogram was inspected visually, and scanned using an LKB enhanced UltraScan XL Laser Densitometer (Pharmacia). The densitometric scan was analyzed with GelScan XL Software, Version 2 (Pharmacia).

Results of such analysis are presented in FIG. 2. It was assumed for convenience that the density of each band was proportional to the amount of that polypeptide synthesized in vitro and, therefore, also proportional to the amount of mRNA coding for the polypeptide. Differences in the densities of corresponding bands between different P.sub.i treatments were thus taken to represent differences in the abundance of the mRNA species that produced that band. One should nonetheless keep in mind that, since the proteins were labeled with .sup.35 S-methionine, the signal is proportional to the methionine content of each polypeptide; to compensate somewhat for this factor, only signals of the same molecular weight were compared between treatments.

The majority of [.sup.35 S]-methionine-labeled translation products were detected in all P.sub.i treatments. Sixteen polypeptides, however, varied in their signal intensities among the three treatments. FIG. 3 is a summary of the standardized data of the expression differences between polypeptides produced from 10 mM P.sub.i -fed, 1.25 mM P.sub.i -fed and P.sub.i -deprived cells. Based on these analyses, P.sub.i deprivation caused the copy number of mRNAs to increase for ten polypeptides, whereas six others decreased. Of translatable mRNAs showing altered expression, four species corresponding to proteins with estimated molecular weights of 31.7, 32.3, 52.5, and 64.8 kDa were only detected in the P.sub.i -starved treatment. By comparison with the other polypeptides, these were expressed at relatively high levels during P.sub.i deprivation. The repression of a 43.5 kDa polypeptide was also noted in minus P.sub.i -treated cells. The other six polypeptides representing mRNAs preferentially expressed during P.sub.i starvation had estimated molecular weights of 19.6, 40.6, 30.1, 37.0, 18.6, and 29.5 kDa. These were expressed at approximately 3.3, 2.8, 2.7, 1.7, 1.3, and 1.2 times higher levels, respectively, in the minus P.sub.i -treated cells than in the 10 mM P.sub.i -fed cells. In addition, there were 20-, 6.6-, 1.8-, 1.6-, and 1.4-fold decreases in the minus P.sub.i -treated cells in the expression of polypeptides with estimated molecular weights of 14.4, 35.9, 48.3, 18.4, and 35.5 kDa, respectively. In the 1.25 mM P.sub.i -fed cells, the mRNAs coding for the sixteen differentially expressed polypeptides appeared to be present either at intermediate levels or at levels similar to those in the minus P.sub.i -treated cells.

No difference was detected between the patterns of gel electrophoresis of the in vitro translation products when using either total RNA or poly(A).sup.+ RNA. The above results were consistent in three independent experiments.

Construction of cDNA Library from Minus P.sub.i -Treated Brassica nigra Cells

Approximately 10 .mu.g of poly(A).sup.+ RNA purified from cells deprived of P.sub.i for 7 days was used to synthesize a double-stranded CDNA library using the c-CLONE II CDNA Synthesis kit (Clontech, Palo Alto, Calif.) according to manufacturer's instructions. The oligo-d(T)-tailed cDNA products produced were fractionated on a Chroma Spin-400 column (Bio/Can Scientific, Mississauga, Canada) to obtain cDNA molecules greater than 400 bp in length. The size range of such molecules was estimated to be from about 0.5 kb to about 3 kb in length. Using EcoRI restriction site sticky ends, the size-selected cDNA molecules were ligated into EcoRI predigested/phosphatase-treated .lambda.ZAPII bacteriophage arms as recommended by the manufacturer (Stratagene, La Jolla, Calif.). Recombinant phages were packaged with Stratagene's Gigapack II Gold and titered on a lawn of E. coli XL1-Blue bacteria grown on LB agar plates according to the manufacturer's protocol. The ligation efficiency at an optimal ratio of cDNA: vector (44 ng: 500 ng) was 7.5.times.10.sup.6 plaque forming units (pfu)/.mu.g cDNA.

Differential Hybridization and Cross-Hybridization Screening of the cDNA Library from Minus P.sub.i -Treated Brassica nigra Cells

The cDNA library from minus P.sub.i -treated B. nigra cells described above was differentially screened by hybridizing to cDNA probes from both minus P.sub.i -treated and 10 mM P.sub.i -fed B. nigra cells, in order to identify genes responsible for the differences in protein and mRNA profiles between these cells.

Single-stranded cDNA probes were synthesized from mRNAs isolated from the P.sub.i -deprived and 10 mM P.sub.i -fed cells to make -P and +P probes, respectively. This was done as previously described (Sambrook et al., 1989), using a mixture of 5 .mu.g of mRNAs and 7.4 .mu.g of random hexadeoxyribonucleotides (Pharmacia). Incorporation of radiolabel was achieved by including .alpha.-.sup.32 P-dATP (ICN) in the reaction mixture. Reaction products were extracted with phenol:chloroform and purified on Sephacryl S-300 columns (Pharmacia).

The unamplified cDNA library was plated on a lawn of E. coli strain XL1-Blue growing at low density (2,000 pfu per 90 mm LB plate). A total of about 50,000 plaques were screened as follows: First, duplicate lifts were prepared from each plate. The plaques' DNA was denatured and immobilized on nitrocellulose filters (Amersham, Oakville, ON, Canada) by standard methods (Sambrook et al., 1989). The filters were baked, prewashed in a solution of 5.times. SSC, 0.5% SDS, 1 mM EDTA (pH 8.0) for 1 h at 68.degree. C. and prehybridized in a solution of 6.times. SSC, 0.05.times. BLOTTO, 25 .mu.g/ml of denatured, fragmented salmon sperm DNA (Pharmacia) at 68.degree. C. for 2-3 h. (1.times.BLOTTO contains 5% non-fat dried milk (Carnation Inc., Toronto) and 0.02% sodium azide (Sigma).) For each pair of duplicate filters, one was hybridized to the radiolabeled -P probes and the other to the radiolabeled +P probes at 68.degree. C. overnight. The filters were then washed under conditions of increasing stringency as follows: three times in 2.times. SSC, 0.1% SDS at room temperature for 5 min.; twice in 1.times. SSC, 0.1% SDS at 68.degree. C. for 1-1.5 h; and once in 0.2.times. SSC, 0.1% SDS at 68.degree. C. for 1 h. (1.times. SSC solution consists of 0.15 M NaCl and 15 mM trisodium citrate.) Autoradiography was performed as described above. Clones that hybridized to -P probes but not to +P probes were identified as "positive". These clones were then subjected to second and third rounds of screening.

Three rounds of screening resulted in the isolation of 131 clones that were preferentially expressed in the starved cells. Because the total number of plaques screened was deliberately large (so as not to miss anything), the 131 clones included multiple separate cloning events of the same gene(s). Therefore, it was necessary to cross-hybridize the isolated clones to each other, in order to distinguish duplicate from novel cloning events.

The isolated clones were digested with EcoRI, PstI and TaqI restriction enzymes and the resulting DNA fragments were separated on 1i agarose gels and transferred to Nytran membranes (Schleicher & Schuell, Keene, NH) in 10.times. SSC overnight (Sambrook et al., 1989). .sup.32 P-labeled single-stranded probes were generated from the liberated B. nigra inserts of individual clones using PCR (Konat et al., 1991), employing T.sub.3 and T.sub.7 primers in the first round and either T.sub.3 or T.sub.7 primers in the second round of reactions.

Membranes to which DNA from the isolated clones was bound were first baked for 30 min. at 80.degree. C., then prehybridized for 5 min. at 65.degree. C. in 0.25 M NaH.sub.2 PO.sub.4 (pH 7.2), 7% SDS, 1 mM EDTA. Next, radiolabeled probe was added and hybridization was allowed to proceed for 2 hr. The membranes were then washed twice in 40 mM NaH.sub.2 PO.sub.4 (pH 7.2), 5% SDS, 1 mM EDTA and twice in 40 mM NaH.sub.2 PO.sub.4 (pH 7.2), 1% SDS, 1 mM EDTA, each time for 30-60 min. at 65.degree. C. Autoradiography was as described above. The membranes were stripped of bound probe by washing twice in 0.1.times. SSC and 0.5% SDS at 95.degree. C. for 20 min.

The results of the cross-hybridization analysis (not shown) permitted the majority of the P.sub.i -inducible clones to be placed into eleven different homology groups, which were designated plant "P.sub.i -starvation responsive" (psr) groups1 to 11. Because these genes are particularly active during periods where phosphate is unavailable, they are assumed to be involved in the plant response to phosphate starvation.

RNA Analysis of psr cDNA Clones Using Northern Blots

The induction and relative abundance of psr mRNAs under the different phosphate growth conditions were further assessed by northern blotting, results of which are shown in FIG. 4.

Cloned psr cDNA inserts were liberated from vector DNA by digestion with EcoRI. The reaction products were electrophoresed on a 1% agarose gel and bands containing insert DNA were excised. This DNA was subsequently purified using GeneClean II (Bio 101 Inc., Vista, Calif.) and radiolabeled by random-priming reactions (Sambrook et al., 1989). The radiolabeled probes were purified using Chroma Spin-30 columns (Clontech, Palo Alto, Calif.). A control DNA probe (.alpha.-tubulin) was similarly radiolabeled and purified.

30.mu.g of total RNA extracted from each of the minus P.sub.i -treated, 1.25 mM P.sub.i -fed and 10 mM P.sub.i -fed cells were electrophoresed on a 2.2 M formaldehyde/ 1% agarose gel (Sambrook et al., 1989) and transferred to Nytran Plus membrane (Schleicher & Schuell) according to the manufacturer's protocol.

Individual blots were incubated at 42.degree. C. for 30 min. in prehybridization buffer that contained 50% formamide, 0.12 M NaH.sub.2 PO.sub.4 (pH 6.8), 0.25 M NaCl, 7% SDS, and 1 mM EDTA. They were transferred to 10 ml of fresh hybridization buffer containing 2-5.times.10.sup.7 cpm of probe at approximately 4 .times.10.sup.9 cpm/ .mu.g specific activity. Hybridization was overnight at 42.degree. C. followed by washing for 30 min. each in 2.times. SSC, 0.1% SDS at room temperature; 0.5.times. SSC, 0.1% SDS at room temperature and 0.1.times. SSC, 0.1% SDS at 65.degree. C. Autoradiography was for 1-4 days. To reuse the blots, bound probes were removed by washing in 0.1% SDS for 5 min, followed by equilibration in 5.times. SSC, 0.1% SDS at room temperature for 20 min. and stripping in the same solution for 2 min. at 95.degree. C.

Based on comparisons to the .alpha.-tubulin internal standard, most of the psr genes were relatively highly expressed and all were induced in both the minus P.sub.i -treated and the 1.25 mM P.sub.i -fed cells, with somewhat less expression in the latter cells. In 10 mM P.sub.i -fed cells, low levels of mRNA expression were observed for psr7, 8, 9, 10 and 11, whereas transcripts for the other genes were not detected. High stringency washing did not remove the additional bands seen in all P.sub.i treatments when probing with psr9, 10 and 11. For each of these, the differentially expressed mRNA species was the smallest size of those detected.

Nuclear run-Off Experiments

Plasmid DNA carrying the B. nigra psr1 cDNA or A. thaliana .alpha.-tubulin inserts were alkaline denatured and applied to Nytran-Plus (Schleicher and Schuell, Guelph, Canada) using Bio-Dot Microfilteration apparatus (Bio-Rad) at five .mu.g per dot. In order to produce probe from newly synthesizing mRNA species, transcriptionally active nuclei were isolated from 5-6 g of 5 mM P.sub.i -fed and P.sub.i -starved root tissues as described (Willimizer and Wagner, 1981). Transcription was allowed in the presence of 32P-UTP for 60 min at 30.degree. C. using the method of Chappel and Hahlbrock (1984). Labelled RNA were purified as described by Somssich et al. (1989). Approximately 10.sup.6 cpm of RNA probe was used for hybridization with the dot blots as described (Malboobi and Lefebvre, 1995). After the last wash, the blot was treated with 20 .mu.g/ml of ribonuclease A in 2.times. SSC for 30 min at room temperature. The blot was then washed with 2.times. SSC, 0.5% SDS, twice and 2.times. SSC, twice. Dot blots were exposed to X-ray film for 7 or more days. The results are shown in FIG. 10.

Plant Culture

Arabidopsis thaliana (var. Columbia) seeds were surface sterilized for ten minutes in 30% bleach (Javex), 0.03% triton X-100 (Sigma) and washed with sterilized water six times. Seeds were transferred onto a 1 cm.sup.2 piece of steel mesh placed on solid MS (Murashige and Skooge) plates containing 0.5% agar and 2% sucrose. After 11 days, plantlets grown and rooted through the mesh were transferred to 15 ml of half strength liquid MS medium containing 1.25 mM P.sub.i and 1% sucrose in 125 ml Erlenmeyer flasks at 24.degree. C., 540 lux light with 80 r.p.m. rotary shaking. Three days later, plants were transferred into MS medium with various concentrations of nutrients as follows. For treatments with differing concentrations of P.sub.i, filter-sterilized KH.sub.2 PO.sub.4 adjusted to pH 5.8 with KOH was added to the 1.25 mM P.sub.i medium up to 5 mM. For the minus P.sub.i treatments, filter-sterilized KCl replaced the KH.sub.2 PO.sub.4 to 5 mM concentration.

DNA Sequencing and Computer Analysis

The psr cDNA inserts were excised in vivo from selected recombinant .lambda.ZAPII phages into Bluescript.TM. plasmid vectors in the presence of R408 helper phage according to supplier's instructions (Stratagene). Plasmid DNA was prepared by CsCl gradient centrifugation (Sambrook et al., 1989).

Both strands of the isolated DNA was then sequenced using a Sequenase Version 2 Kit (United States Biochemical Corp., Cleveland, Ohio) with T.sub.3 and T.sub.7 primers, and other appropriate primers along the sequence (Stratagene). Sequencing of the 5' and 3' ends of these clones immediately indicated clear distinctions between the eleven psr groups.

Homology searches on the obtained sequences were performed with the BLASTX program (Gish et al., 1993) against the GenBank database through NCBI (The National Center for Biotechnology Information). Assembling and editing of the coding sequence and analysis of DNA and predicted protein sequences was performed using related programs of LASERGENE software for Macintosh (DNASTAR, Madison, Wis.).

Clone psr1 was identified as a gene coding for a phosphate-starvation inducible protein kinase. It has therefore been given the additional name psrPK. The psrPK sequence possesses high homology to protein kinases isolated from other plants, such as Glycine max protein kinase 2 (SPKZ, GB accession #Ll9360, 63% homology), Arabidopsis thaliana protein kinase 2 (ASK2, GB Accession # Z12120, 70% homology) (Park et al., 1993), Brassica napus serine threonine kinase 1 (BSK1, GB Accession #L12393, 69% homology), Glycine max protein kinase 3 (SPK3, GB Accession #L19361, 76% homology), Brassica napus serine threonine kinase Z (BSKZ GB Accession # L12394, 71% homology), Arapidopsis thaliana protein kinase 1 (ASK1, GB Accession # P43291, 71% homology) (Park et al., 1993).

An A. thaliana .lambda.PRL2 cDNA library (CD4-7) was obtained from the Ohio State Arabidopsis Biological Resource Center.

It was screened at high stringency with a probe consisting of the entire B. nigra psrPK cDNA insert. The B. nigra psrPK cDNA insert was used for random priming probe synthesis and subsequent hybridization in non-radioactive Du Pont's Renaissance.TM. kit according to the manufacturer (Du Pont NEN, Boston, Mass.). A strongly hybridizing plaque (designated psr1--1) was purified and its bacteriophage DNA isolated. The A. thaliana insert of the phage was subjected to dideoxy nucleotide sequencing of both strands after in vivo excision of Bluescript plasmid.

FIG. 5 shows the cDNA sequence of B. nigra psrPK, aligned with the cDNA sequence of the corresponding protein kinase from Arabidopsis thaliana.

Genomic Clone Isolation

A genomic library of A. thaliana (Var. Colombia) in EMBL3 is screened at high stringency with a probe consisting of the unique 3' sequence of the A. thaliana psrPK cDNA insert. This insert is used for random priming probe synthesis and subsequent hybridization in non-radioactive Du Pont Renaissance.TM. kit according to the manufacturer (DuPont NEN, Boston). Positive clones are then rescreened until homogenous and subjected to Southern blot analysis using the same probe as above. Inserts from positive clones are excised and digested with appropriate restriction enzymes and subcloned into plasmids. The inserts are then sequenced by dideoxy nucleotide sequencing of both strands.

Plant Transformation with psrPK Constructs

Arabidopsis thaliana was transformed in planta with eight different constructs employing constitutive and tissue-specific promoters attached to sense and antisense nucleic acids of the entire and partial sequences of psrPK from A. thaliana. See FIGS. 12A-12D.

In these constructs, the GUS gene present in the pBI121 vector (CLONTECH, Palo Alto, Calif., www.clontech.com) was replaced by the psrPK gene in either a sense (psr1) (FIG. 12A) or antisense (.alpha.-psr1) (FIG. 12B) direction to produce a sense or antisense construct under the control of a constitutive (CMV-35S) promoter. The CMV-35S promoter (cauliflower mosaic virus 35S promoter) of pBI121 is fused upstream of GUS gene. The GUS gene was removed from this vector by SmaI and EcoRI digestion. A cDNA encoding psrPK was cloned in pZL1 vector (isolated from Arapidopsis Resource Center cDNA library). This clone was digested by SmaI and BamHI enzymes. The BamHI site was subsequently filled in by Klenow fragment of DNA polymerase I. The resultant vector and psrPK gene were subjected to blunt-end ligation. As a result, both sense and antisense construct of psrPK genes under the control of CMV-35S promoter were obtained.

Competent E. coli DH 5-.alpha.was transformed by the ligation products and plated on LB/kan. The growing colonies were picked and mini-prepped. Digestion with SalI and EcoRI enzymes distinguished the sense and antisense constructs by appearance of 1.6 Kb and 0.3 Kb fragments, respectively.

Constructs depicted in FIGS. 12C and 12D were produced in a similar manner except that the promoterless pBI101 vector was used and an Arabin promoter (Arabin-pro) was inserted as a HindIII-SalI fragment fused upstream of the GUS gene in the pBI101vector. The GUS gene present in the promoterless pBI101 vector (CLONTECH, Palo Alto, Calif., www.clontech.com) was then replaced by the psrPK gene in either a sense (psr1) (FIG. 12C) or antisense (.alpha.-psr1) (FIG. 12D) direction to produce a sense or antisense construct under the control of a seed-specific (Arabin) promoter.

The in planta transformation protocol is described by Katavic et al. (1994). Briefly, Agrobacterium tumefaciens strain GV3101 bearing the helper nopaline plasmid MP90 and a binary vector containing the psrPK gene construct and a plant selectable marker was grown overnight. Wound sites of excised primary and secondary inflorescence shoots were exposed to cultures of the transformed Agrobacterium cells three times to inoculate the plant tissues.

The treated plants are grown to maturity, and the seeds are harvested and screened for transformants on selective medium. Confirmation of transformation is made by determining if the plants contain the transferred genes through Southern blots or polymerase chain reaction techniques using the psrPK and associated sequences.

Bacterial Expression of psrPK and Determination of Protein Kinase Activity

The psrPK protein was expressed in the E. coli expression vector pGEX (Promega). The insert was amplified out of the Bluescript plasmid containing the Arabidopsis psrPK such that a fragment was produced which contained the translational start and which stopped one codon short of the stop codon (i.e. excluding the stop codon). This fragment was cloned into a modified PGEX plasmid containing six extra codons for histidine at the 3' end of the inserted psrPK cDNA. The protein was then expressed in the bacteria and the psrPK protein was purified from crude extract using columns which exploit the affinity properties of the added histidine residues.

Protein kinase activity was determined by three different experiments using the purified psrPK protein. Manser, et al. (1994); Manser, et al., (1992); Manser, et al., (1995).

The first two experiments involve activity determinations on proteins obtained from plants grown in minus phosphate. Between 1-5 g of plant tissue was homogenized in a buffer containing 15 mM Hepes/KOH pH 7.6, 40 mM KC1, 5mM MgCl.sub.2, 1 mM dithiothreitol (DTT), 0.1 mM phenylmethylsulfonyl fluoride (PMSF) (Sigma). The homogenate was kept on ice for 30 min. before centrifuging at 13000 .times.g for 15 min, twice. The protein concentration was determined by using Bio-Rad Protein Assay dye Reagent Concentrate as described by the manufacturer (Bio-Rad Lab., Richmond, Calif.). Fifty .mu.g of each protein extract was loaded on to a denaturing SDS-PAGE or a native gel (Lammeli, 1970). For the SDS-PAGE, the final concentration of acrylamide monomer concentration in the 0.75 mm min gel (Bio-Rad) was 4k for the staking gel and 10% for the separating gel. The SDS-PAGE was run at 200V at room temperature and stained with Coomassie R-250 (Sigma). SDS was eliminated form the native gel composition in which the final concentration of acrylamide monomers was 3% for the stacking gel and 7% for the separating gel. The gel was run at 4.degree. C. at 200V for 1 hr prior to loading samples and then run at 200V for 45 min. at 4.degree. C.

The separated proteins were blotted onto Immobilon P PVDF membrane (Millipore, Mississallga, Ontario) and, in the case of the SDS denaturing samples, the blots were exposed to denaturing steps of 6M Guanidine Hcl in MES buffer, diluted 50% with MES buffer, five cycles, followed by a renaturing step of PBS buffer for 3 hours. These were then exposed to 25 mM MES, pH 6.5 buffered solution containing either purified protein and 25 .mu.Ci .gamma..sup.32 P-ATP alone or 25 .mu.Ci .gamma..sup.32 P-ATP for 5 min. at 22.degree. C., then 10 min. at 4.degree. C. The blots were then washed, dried, and exposed to X-ray film for detection purposes.

For native gel separation, the blots were immediately exposed to 25 mM MES, pH 6.5 buffered solution containing either purified protein and 25 .mu.Ci .gamma..sup.32 P-ATP or 25 .mu.Ci .gamma..sup.32 P-ATP alone for 5 min. at 220.degree. C., then 10 min. at 4.degree. C. These blots were also washed, dried and exposed to X-ray film for detection purposes.

The third activity experiment used casein or histones as artificial substrates for psrPK (Uesono, et al., (1992)). The psrPK protein expressed and purified from bacteria was dialyzed into 20 mM Tris HC1 (pH 8.0), 10 mM MgCl.sub.2, and 1 mM .beta.-mercaptoethanol. An equal volume of this mixture was added to 20 .mu.M ATP, 2 .mu.M/ml dephosphorylated casein (or histone) and 25 .mu.Ci .gamma..sup.32 P-ATP. The sample was run on an SDS-Page gel as described above and the gel dried and exposed to X-ray film for detection purposes. The psrPK protein phosphorylated both casein and histone.

Plant Culture for psr .beta.-Glucosidase Expression Analysis Under Other Stresses

Arabidopsis thaliana (var. Columbia) seed were germinated and grown essentially as described in Example 8. The concentration of P.sub.i was kept at 5 mM when investigating responses to other environmental stresses. For the high salt treatment, sterilized NaCI solution was added to a final concentration of 100 mM, a sublethal concentration (Saleki, et al., (1993). For media with no nitrogen, KNO.sub.3 and NH.sub.4 NO.sub.3 were replaced by an equal molarity of KCI. For medium lacking sulphur, MgSO.sub.4 was replaced by an equal molarity of MgCl.sub.2. Heat shock was performed by incubating 14 day-old plants at 390.degree. C. for 2 hours. Anaerobic conditions were created by blowing argon gas into the flasks containing 13 day-old plants through sterilized tubes plugged with cotton for 24 hours. In all cases, the culture medium was removed and replaced with fresh medium every 4 days to ensure that there was no depletion of supplied nutrients. Treated plants were harvested after 14 days except for plants grown without nitrogen that were harvested on day 11 due to onset of severe deprivation symptoms, and plants starved for P.sub.i for 14 days and resupplied with 5 mM P.sub.i that were harvested after a further 1 or 3 days. Only P.sub.i deprivation caused significant increases in MRNA levels for .beta.-glucosidase.

Southern Blots and Genomic Library Screening

Genomic DNA was extracted from A. thaliana plant material in a CTAB extraction buffer according to Saghai-Maroof and colleagues 38]. About 10 .mu.g of genomic DNA was digested with either BamHl, EcoRI, Sall, or BamHI/SalI restriction enzymes overnight at 370.degree. C. After separating the digestion products on a 0.8% agarose gel, DNA fragments were transferred on to Nytran-Plus membrane as described by the manufacturer (Schleicher and Schuell, Guelph, Canada). The Brassica nigra psr3.1 CDNA insert (Malboobi and Lefebvre, (1995)) was used for random priming probe synthesis and subsequent hybridization using the non-radioactive DuPont Renaissance.TM. system according to the manufacturer (Du Pont NEN, Boston, Mass.).

A genomic library of A. thaliana ecotype Columbia cloned into EMBL3 was provided by Kenton Ko, Queen's University, Kingston, Canada. About 200,000 plaque forming units (pfu) were screened with probe derived from he B. nigra psr3.1 cDNA clone at high stringency conditions (Malboobi and Lefebvre, (1995)). Positive clones were carried through secondary and tertiary screening. Probes derived from the isolated genome DNA inserts were used in Southern blotting to determine which genomic clones corresponded to the B. nigra psr3.1. A genomic clone with a similar blotting pattern to that of B. nigra psr3.1 cDNA clone was chosen for restriction enzyme site mapping and subcloning by standard methods (Sambrook, et al., (1989)).

RNA Isolation and Northern Blots

Total RNA was extracted from plant tissues according to Chirgwin and colleagues (Chirgwin, et al., (1979). Twenty five .mu.g of each RNA extract was loaded or to a 1% agarose/formaldehyde gel (Sambrook, et al., 1989). Northern blotting and laser densitometric scanning of autoradiograms were carried out as previously described (Malboobi and Lefebvre, (1995)).

Sequence Determination and Computer Analysis

The restriction enzyme DNA fragments of EcoRI, and EcoRI/SalI digestions of the psr3 genomic clone were prepared and inserted into the Bluescript KS-vector (Stratagene, La Jolla, Calif.) and used to transform competent E. coli strait DH5-.alpha.(GIBCO BRL, Burlington, Canada) through standard cloning techniques (Sambrook, et al., 1989). Plasmid DNA was prepared with the Wizard.TM. Megapreps DNA Purification System (Promega, Madison, Wiss.). Both strands of the inserts were sequenced by dideoxy nucleotide method in a Sequenase Version 2 Kit (United States Biochemical Corp., Cleveland, Ohio). Homology searches of databases were conducted using the BLASTX program (Gish and State (1993) against DNA and protein sequences. Assembling and editing of the coding sequence and analysis of DNA and predicted protein sequences was performed using the appropriate prograrcks of LASERGENE software or Macintosh (DNASTAR, Madison, Wis.). Similar sequencing and homology searches were performed for all cDNA clones of psr genes.

Primer Extension Analysis

Transcriptional start sites for .beta.-glucosidase were determined by primer extension analysis. The oligonucleotide, AGCAAAAGCGCCCATGAGAGGAA, was labelled with T4 poly-nucleotide kinase (Promega, Madison, Wis.) in the presence of [.gamma.-.sup.32 P] -DATP as described (Sambrook, et al., (1989)). Labelled oligonucleotides were purified using the MERMAID system (Bio/Can Scientific, Mississauga, Canada) and annealed to RNA extracted from P.sub.i -.starved roots for primer extension by AMV reverse transcriptase (Pharmacia, Baie D'Urfe, Canada) as described in Ausubel, et al., (1995).

Protein Extraction and gel Electrophoresis for .beta.-Glucosidase

Approximately ten mg fresh wt of root tissue was homogenized in 500 .mu.l of a buffer containing 15 mM HEPES/KOH pH7.6, 40 mM KCI, 5 mM MgCl.sub.2, 1 mM dithiothreitol (DTT), O. 1 mM phenylmethylsulfonyl fluoride (PMSF) (Sigma, St. Louis, Mo.). The homogenate was kept on ice for 30 min. before spinning at 13000 g for 15 min. The supernatant was removed and centrifuged for a further 15 min. The protein concentration of this final supernatant was determined using Bio-Rad Protein Assay Dye Reagant Concentrate as described by manufacturer (Bio-Rad, Richmond, Calif.). Fifty .mu.g of total protein was run in each lane in either denaturing SDS-PAGE or native PAGE gels (Laemeli, (1970)). For the SDS-PAGE, the final concentration of acrylamide monomer in the 0.75 mm thick mini-gel (Bio-Rad) was 4% and 10% in the stacking and separating gels, respectively. The gel was run at 200V at room temperature and stained with Coomassie R-250 (Sigma). For the native gel, SDS was eliminated from all reagents and the final concentrations of acrylamide monomer were 3k and 7% for the stacking and separating gels, respectively. The native gel was prerun at 40.degree. C. and 100 V for 30 min prior to sample loading and then run at 200V for 3 h at 40.degree. C. To detect .beta.-glucosidase activity, the native gel was equilibrated in a 100 mM sodium acetate, pH 6.5 (Sigma) buffer containing 20 mM CaCl.sub.2 for 15 min. This was followed by incubation for 3 hours in the same solution plus 0.02% (w/v) Fast Garnet GBC salt (Sigma) and 0.04% (w/v) .beta.-naphthyl .beta.-D-glucopyranoside (Sigma) at room temperature.
