Description:
FIELD OF THE INVENTION 
     This invention relates to nucleotide sequences encoding a plant enzyme, vectors containing said nucleotide sequences, hosts containing said nucleotide sequences, amino acid sequences encoded by said nucleotide sequences, recombinant DNA methods of producing the enzyme, and a method of altering the properties of a plant. 
     BACKGROUND OF THE INVENTION 
     Fruit and vegetable cell walls are largely polysaccharide, the major components being pectin, cellulose and xylogucan (Selvendran &amp; Robertson, IFR Report 1989). Numerous cell wall models have been proposed which attempt to incorporate the essential properties of strength and flexibility (e.g. Albersheim, 1975 Sci. Am. 232, 81-95; Albersheim, 1976 “The primary cell wall”, Plant Biochemistry, 3rd Edition, Academic Press; and Hayashi, 1989, Ann. Rev. Plant Physiol. &amp; Plant Mol. Biol. 40, 139-168). 
     Xyloglucans are 1,4-β-glucans that are extensively substituted with α-1,6-xylosyl side chains, some of which are 1,2 β-galactosylated. They are found in large amounts in the primary cell walls of dicots but also in certain seeds, where they serve different roles. 
     Primary cell wall xyloglucan is tightly hydrogen bonded to cellulose microfibrils and requires concentrated alkali or strong swelling agents to release it. Xyloglucan is thought to form cross-bridges between cellulose microfibrils, the cellulose/xyloglucan network forming the major load-bearing/elastic network of the wall. DCB mutated suspension culture cells (cell walls lacking cellulose) release xyloglucan into their media, suggesting that xyloglucan is normally tightly bound to cellulose. 
     Hydrolysis of primary cell wall xyloglucan has been demonstrated in segments of dark grown squash hypocotyls, during IAA induced growth (Wakabayashi et al., 1991 Plant Physiol. 95. 1070-1076). Endohydrolysis of wall xyloglucan is thought to contribute to the wall loosening which accompanies cell expansion (Hayashi, cited previously). The average molecular weight of xyloglucan has also been shown to decrease during tomato fruit ripening and this may contribute to the tissue softening which accompanies the ripening process (Huber, 1983 J. Amer. Soc. Hort. Sci. 108, 405-409). 
     Certain seeds, e.g. nasturtium, contain up to 30% by weight of xyloglucan, stored in thickened cotyledonary cell walls, which serves as a reserve polysaccharide and is rapidly depolymerised during germination. 
     An endo 1,4 β-D glucanase which specifically acts on xyloglucan (i.e. a xyloglucanase) has been isolated and purified to apparent homogeneity from germinating nasturtium ( Tropaeolum majus  L.) seeds (Edwards et al., 1986 J. Biol. Chem. 261, 9494). 
     The purified xyloglucanase gives a single polypeptide band on SDS polyacrylamide gel electrophoresis, (apparent molecular weight, 29-31 kDa) and isoelectric focusing (isoelectric point, 5.0). The enzyme displays an absolute specificity for xyloglucan and an endo mode of action, as determined by end product analysis following hydrolysis of tamarind seed xyloglucan (Wakabayashi et al., cited above). Although the natural substrate of the enzyme is nasturtium cotyledonary reserve xyloglucan, it has also been shown to hydrolyse primary cell wall xyloglucans in vitro (Edwards et al., cited previously). At high substrate concentrations, xyloglucan endo-transglycosylase (XET) activity has been demonstrated (Fanutti et al., 1993 The Plant Journal 3, 691-700). 
     The nucleotide sequence of this nasturtium xyloglucanase/XET enzyme has been determined and is disclosed in International Patent Application No. WO 93/17101 and by de Silva et al., (1993 The Plant Journal 3, 701-711). 
     Similar enzyme activity has been detected in other plant tissue and shown to be positively correlated with growth rate in different zones of the pea stem (Fry et al., 1992 Biochem. J. 282, 821-829). It has been proposed that XET is responsible for cutting and rejoining intermicrofibrillar xyloglucan chains and that this causes the wall-loosening required for plant cell expansion. XET activity has also been demonstrated in tomato fruit (xyloglucanase apparently activatable by xyloglucan oligosaccharides) where it is reportedly highest at the 2 days post-“breaker” stage of ripening (Machlachlan &amp; Brady, 1992 Aust. J. Plant Physiol. 19, 137-146) and may be involved in the softening process. 
     This application describes the isolation from tomato plants of a nucleotide sequence which encodes an XET activity. 
     SUMMARY OF THE INVENTION 
     In a first aspect the invention provides a polypeptide having xyloglucan endo-transglycosylase (XET) activity, comprising substantially residues 21-289 of the amino acid sequence of FIG. 1 (Seq ID No. 2), or functional equivalents thereof. 
     The term “functional equivalent” as used herein and applied to an amino acid sequence is intended to refer to those amino acid sequences having the same functional characteristics as the sequence of the invention but which have slightly different sequences. Generally, for example, it is well known that one may make a “conservative” substitution, exchanging one amino acid residue in a sequence for another residue with very similar properties, without having any significant effect on the function of the polypeptide. 
     An example of a functionally equivalent polypeptide sequence is shown in FIG. 5 (Seq ID No. 8). The amino acid sequences shown in FIGS. 1 and 5 are directly compared in FIG.  6 . 
     Further, one or more amino acid residues may be deleted or added without significant deleterious effect. It will be apparent to those skilled in the art that such changes may particularly be made at points in the sequence which are not evolutionarily conserved. Enzyme precursors are also included within the meaning of “functional equivalents” and also mature, processed enzymes lacking signal sequences. In the present case amino acid residues 1-20 of FIG. 1 are believed to constitute such a signal sequence and are therefore not essential for enzyme activity. Likewise, amino acid residues 1-18 of the sequence shown in FIG. 5 are thought to comprise a non-essential signal sequence. 
     In specific embodiments therefore the invention may provide a polypepide having XET activity and comprising residues 1-289 of the sequence shown in FIG. 1; or residues 19-287 of the amino acid sequences shown in FIG. 5; or residues 1-287 of the amino acid sequence shown in FIG.  5 . 
     Preferably such functional equivalents will exhibit at least 80% homology, and more preferably at least 85% homology, and most preferably at least 90% homology, with the amino acid sequence of the invention. 
     The present inventors have, by analysis of the amino acid sequence data, identified a number of peptide sequences which are thought to be relatively conserved within functional equivalents of the sequence of the invention. 
     Preferably, functional equivalents will comprise substantially one or more of the following peptide sequences (which will generally be perfectly conserved but may contain up to one or, at most, two amino acid differences): 
     DEIDFEFLGN; SLWNADDWAT; FYSKNEYLFG; and GTVTTFYLSS; (Seq ID Nos. 3-6 respectively). 
     Desirably the polypeptide is substantially in isolation from other plant derived substances. 
     In a second aspect the invention provides a nucleotide sequence encoding the amino acid sequence of FIG. 1 (Seq ID No. 1), or functional equivalents thereof. 
     Preferably the nucleotide sequence comprises the nucleotide sequence of FIG. 1 or other functionally equivalent sequences obtainable from tomato plants. The term “functional equivalent” as used herein and applied to nucleotide sequences is intended to refer to nucleotide sequences encoding a polypeptide having the same functional characteristics as the amino acid sequences of the first aspect and includes nucleotide sequences which will hybridize under standard conditions (described by Sambrook et al. 1989, Molecular Cloning: A Laboratory Manual) to the complement of the nucleotide sequence of FIG.  1 . Preferably the functionally equivalent nucleotide sequence will exhibit at least 70% homology, more preferably 80% homology and most preferably at least 85% homology with the nucleotide sequence of FIG. 1. A specific example of a functionally equivalent nucleotide sequence is shown in FIG. 5 (Seq ID No. 7). 
     For the purposes of the present specification, the term “functional equivalent” also refers to “anti-sense” sequences which hybridise under standard conditions to the nucleotide sequence of FIG.  1 . Such sequences have utility in down-regulating the expression of the nucleotide sequence of the invention. Preferably such anti-sense functional equivalents will exhibit at least 70% homology, more preferably at least 80% homology, and most preferably at least 90% homology with the complement of the nucleotide sequence of FIG.  1 . In general, anti-sense functional equivalents will preferably exhibit higher percentage homology than sense equivalents. This is because sense constructs will be translated into polypeptides which will be functional and which may contain conservative amino acid substitutions. In contrast, anti-sense constructs will, in the vast majority of instances, function at the level of nucleic acid rather than polypeptide, and thus any base sequence differences will tend to reduce the usefulness of the construct. 
     Those skilled in the art will understand that, with the benefit of the disclosure herein relating to the nucleotide and amino acid sequences of the invention, it will be simple to detect, isolate and clone (e.g. by PCR) other nucleotide sequences which are functionally equivalent to the nucleotide sequence of the invention. Suitable methods, for example, are taught by Sambrook et al. Of particular usefulness in such routine work may be the peptide sequences disclosed above. Also, the polypeptide of the invention (or peptides derived therefrom) may be used to generate antibodies for use in immunological screening of putative functionally equivalent sequences. 
     It is preferred that the sequence of the second aspect of the invention further comprises a 5′ untranslated region including a suitable promoter, to enable expression in host cells. 
     The invention also provides a vector comprising the nucleotide sequence of the second aspect of the invention, and a host cell comprising the nucleotide sequence of the invention. 
     In one embodiment, the vector is capable of expressing the nucleotide sequence, so as to produce the polypeptide of the invention. (Other vectors may comprise an antisense functionally equivalent nucleotide sequence). 
     Thus, in a further aspect, the invention provides a method of producing a polypeptide having XET activity, comprising the steps of: introducing into a suitable host cell a vector capable of directing the expression of a polypeptide as defined above, growing the host cell and/or the progeny thereof in suitable culture conditions so that the polypeptide is expressed, followed by obtaining the polypeptide from either the culture medium and/or the host cells. 
     It is preferable, but by no means essential, that the host cell is eukaryotic, as a eukaryotic host is more likely to express the enzyme in a fully functional conformation. 
     Suitable vectors are known which can be used to introduce and express the sequence of the invention in plants. 
     In a further aspect the invention provides a method of transforming a host cell, comprising the introduction into the host cell of the nucleotide sequence of the second aspect of the invention. Preferably the host cell is a plant cell. Preferably the transformed plant cell comprises part of a plant. 
     As will be apparent to those skilled in the art, the introduction of the nucleotide sequence of the invention into a plant or part thereof would be expected to alter the characteristics of the plant or part thereof. 
     In a still further aspect, the invention provides a method of altering the characteristics of a plant or part thereof, comprising introducing into the plant or part thereof an effective portion of the nucleotide sequence of the invention or a functional equivalent thereof, so as to alter the level of XET activity in the plant or part thereof. Preferably the method is such as to reduce the level of XET activity in the plant or part thereof, typically by introducing an antisense sequence. Preferably the effective portion will comprise at least 50%, more preferably at least 70%, and most preferably at least 90% of the nucleotide sequence of the invention? 
     In another aspect, the invention provides a genetically engineered plant having characteristics altered by the method defined above, or the progeny of such a plant. 
     The altered plant is preferably any commercially important plant (including fruit or vegetable plants) where there is sufficient knowledge to perform the method of the invention and in which xyloglucan has a structural function (i.e. dicots and non-Grarinaceous monocots). 
     Such plants include: alfalfa, apple, broccoli, cabbage, carrot, cauliflower, celery, cotton, cranberry, cucumber, eggplant, flax, grape, horseradish, kiwi, lettuce, mangoes, melon, oilseed rape, papaya, pea, peaches, pears, peppers, plum, poplar, potato, raspberry, soybean, spruce, strawberry, sugarbeet, sweet potato, tobacco, tomato and walnut. 
     It will be appreciated that the characteristics of the whole plant need not be altered. It may be desirable to alter the properties of parts of the plant (e.g. seeds, fruit). This could be achieved, for example, by the use of tissue-specific promoters to regulate transcription of the introduced sequence. 
     The method of the invention would be expected to alter levels of XET activity and thus the frequency of breaking and re-forming of cell wall cross-links (consisting of xyloalucan molecules) resulting in wall loosening which may permit cell expansion. Moreover, in view of the important structural role of xyloglucan, one might expect the characteristics which might be altered to include: size, rate of growth, and texture, especially during ripening.

     DETAILED DESCRIPTION OF THE INVENTION 
     EXAMPLES 
     Example 1 
     Following complete sequencing of a cDNA encoding nasturtium seed XET (described in pending International Patent Application No. WO 93/17101), primers were designed to attempt PCR amplification of similar gene fragments from tomato. Two of the primers (NXG2H and NXG2B, shown below) overlapped with a region homologous to a  Bacillus macerans  β-1,3-1,4-glucanase (the region having the amino acid sequence DEIDIEFLG). The other primers corresponded to regions adjacent to or surrounding histidine residues; (these are often present in active sites of hydrolytic enzymes, and active sites of enzymes of similar function often having primary sequence homology). These corresponded to amino acid sequences PNHNRVD (primer NXG1H), HDEIDIE (primers NXGH2H and NXG2B), HLWFDPT (primers NXG3H and NXG3B) and TRDHTLT (primer NXG4B) (Seq ID Nos. 35-38, respectively).

     These primers were completely conserved with respect to the nasturtium sequence and incorporated restriction enzyme recognition sites at their 5′ ends to facilitate cloning of PCR products. However all attempts to amplify tomato DNA by PCR, using any combination of the above primers, proved unsuccessful. 
     The deduced amino acid sequence of nasturtium seed XET shares some regions of homology (42% identity in a 151aa overlap) with a sequence deduced from a genomic clone and cDNA from  Arabidopsis thaliana  (Medford et al., 1991 The Plant Cell 3, 359-370). The polypeptide encoded by the genomic clone is termed meri-5 and its function is currently unknown. 
     It was decided to attempt PCR amplification of tomato DNA using a mixture of degenerate oligonucleotides (XG 117 and XG 162, shown below) corresponding to two of these regions conserved between nasturtium XET and meri-5, although there was little expectation of success in view of the previous failures and the lack of knowledge concerning the function (if any) of meri-5. 
     Surprisingly, PCR succeeded in amplifying a 122 bp tomato genomic DNA fragment having significant sequence homology to both meri-5 and nasturtium XET. 
     The experiment was performed as described below. 
     Genomic DNA was isolated from young tomato leaf tissue (cultivar VF 143B-7879, available from the Tomato Genetics Stock Centre, Department of Vegetable Crops, University of California, Davis, Calif. 95616), as described by Dellaporta et al. (1983, Plant Mol. Biol. 1, 19-21). 
     The degenerate oligonucleotide mixtures were designed corresponding to the conserved regions DEID(I/F)EFLG (XG 117, Seq. ID No. 39) and HLWFDPT (XG 162, Seq. ID No. 37), as shown below: 
     XG 117 5′ GA(C/T) GA(A/G) ATI GA(C/T) (A/T)T(A/C/T) GA(A/G) TT 3′ (sense) 
     XG 162 3′ GT(G/A) (G/A)A(G/A/T/C) ACC AA(G/A) CT(G/A) GGI TG 5′ (antisense) (Seq ID Nos. 15 and 16 respectively) 
     The degenerate oligonucleotides were then used as primers in the following reactions (each reaction having a total reaction volume of 100 μl): 1-2 μg genomic DNA; 100 picomoles each of XG 117 and XG 162; dGTP, dATP, dTTP and dCTP all at 0.2 mM; 10 mM Tris-HCl pH 8.3; 50 mM KCl; 1.5 mM MgCl 2 ; 0.01% (W/V) gelatin; and 2.5 units Taq DNA polymerase (Stratagene). 
     Thermal cycling was carried out in an MJ Research programmable thermal controller with an initial denaturing step of 94° C. for 2 minutes, followed by 35 cycles of 94° C. for 1 minute, 40° C. for 2 minutes and 72° C. for 2 minutes. Amplification products were fractionated on a 2% agarose/TBE gel containing 0.5 μg/ml ethidium bromide and viewed on a UV transilluminator. DNA fragments were purified from gels using DEAE paper, as described by Sambrook et al. (Molecular Cloning: a laboratory Manual). 
     The main PCR product was found to be 122 bp in size. This was ligated into pT7Blue (obtained from AMS Biotechnology) and subjected to DNA sequence analysis. Of the four clones sequenced, three had identical DNA sequences (PX3) and one differed in both DNA and deduced amino acid sequence (PX1), as shown in FIG.  2 . In FIG. 2, Tom 3 and Tom 1 represent the deduced amino acid sequence for PX3 and PX1 respectively, as compared with Meri-5 and nasturtium XET. 
     In order to obtain more extensive sequence information, a tomato cDNA 5′ stretch library was obtained from Clontech Laboratories Inc. (prepared using mRNA from the “breaker” stage of ripening fruit from tomato, “Ailsa craig” cultivar VFN8); this was primed with oligo-(dT) and random primers to synthesise cDNA, which was packaged in phage lambda gt11. 
     Approximately 200,000 cDNA clones from this library were screened using the 122 bp PCR fragment as a radiolabelled probe. Briefly, 25-30 ng of gel-purified 122 bp amplification product were denatured in 9 μl H 2 O by heating at 100° C. for 5 minutes and then cooling on ice. The fragments were radio-labelled with  32 P-dCTP (Amersham International plc) using a kit supplied by United States Biochemicals Inc. (Sequenase v2.0). Unincorporated nucleotides were removed by chromatography through a Sephadex G-50 column. 
     Using this probe, a number of positively-reacting clones were detected in the cDNA library. These were eluted from top layer agarose into 0.1-lml SM (50 mM Tris-HCl pH 7.5, 10 mM MgSO 4 , 100 mM NaCl, 0.01% w/v gelatin) and purified by further rounds of screening. The insert was isolated from the bacteriophage either by direct PCR of the stock suspension or by digestion of isolated DNA. 
     For PCR of the stock suspension, purified bacteriophage stocks (5 μl, 10 5 -10 6 pfu) were heated at 100° C. for 5 minutes and added to a solution identical to that described previously except that 20 pmols each of gtll 5′ and 3′ oligonucleotides (Clontech) were used instead of the degenerate ones. Thermal cycling was as follows: 2 minutes at 94° C., 25 cycles of 1 minute at 94° C., 1 minute at 55° C. and 2 minutes at 72° C., followed by a final step of 5 minutes at 72° C. Amplification products were gel-purified on 1% agarose gels as above. 
     Gel-purified PCR-amplified products were ligated into pT7 Blue PCR cloning vector (AMS Biotechnology Limited) and transformed into competent  E. coli  according to the manufacturer&#39;s instructions. 
     Colonies containing recombinant plasmids were used to inoculate 30 ml Lennox broth containing 50 μg/ml ampicillin and 12.5 μg/ml tetracycline; after overnight growth at 37° C., purified plasmid DNA was obtained from the culture using a “Plasmid midi” kit supplied by Qiagen Inc. Restriction analysis of the cloned products was carried out using enzymes and buffers supplied by Amersham International plc, followed by agarose gel electrophoresis. 
     DNA was sequenced using kits and protocols supplied by United States Biochemicals Inc. (Sequenase v2.0). Recombinant plasmids (Qiagen-prepared) were either sequenced directly or restriction fragments were subcloned into M13 to produce single-stranded templates. Reaction products were fractionated on 30 cm×40 cm×0.4 mm polyacrylamide gels using BRL 6% acrylamide solutions. An IBM computer with DNAstar software was used to analyse resultant sequences. 
     Clones were found to vary in size between 500 and 1400 bp. One clone, termed clone tXET-B1 (or “B1” for simplicity), was found to possess internal HindIII and SacI recognition sites which facilitated subcloning into M13. Internal primers were also used in order to sequence the clone fully and in both directions (FIG.  3 ). The sequences of these internal primers (8-TH, 8-HS sense primers and 8-TB, 8-HT antisense primers) are as follows: 
     8-TH: 5′ CGATGCAGCTGGAATTTCA 3′ 
     8-TB: 5′ AGTTTGAGCTGCATATCGAA 3′ 
     8-HS: 5′ TTTGATCCCACCTCGCCGTT 3′ 
     8-HT: 5′ CAGCTGACCAAACACAAGCA 3′ 
     (Seq ID Nos. 17-20 respectively) 
     The sequences of the other primers were: 
     T3: 5′ ATTAACCCTCACTAAAGGGA 3′ 
     T7: 5′ TAATACGACTCACTATAGGG 3′ 
     U19: 5′ GTTTTCCCAGTCACGACGT 3′ 
     (Seq ID Nos. 21-23 respectively) 
     U represents the M13 (-40) primer. Initially, two sequences were found, each from a different PCR amplification from the lambda stock. They differed in 2 base pairs within the putative coding region. Since these differences were probably due to the inaccuracy of the thermostable DNA polymerase used in the PCRs, lambda DNA was prepared and the cDNA ligated into pBluescript SK+, in order to obtain definitive sequence data (FIG.  1 ). The definitive nucleotide sequence of clone B1 is shown in FIG. 1, together with the deduced amino acid sequence. 
     The putative open reading frame of clone B1 encodes a 289 amino acid polypeptide of predicted molecular weight 32.7 kDa. This has 39% identity in 270 overlapping amino acids with nasturtium XET and 59% identity in an overlap of 186 amino acids with meri-5. 
     A signal peptide is predicted on the basis of hydrophobicity of amino acids in positions 1-25, and statistical analysis of the amino acid sequence predicted that the precursor is cleaved between alanine and aspartate residues at positions 20 and 21 (Von Heijne, 1983 Eur. J. Biochem. 113, 17-21). 
     The region of clone B1 corresponding to the genomic PCR fragments (aa 103-129) shows differences in the deduced amino acid sequence compared to both of the genomic fragment sequences. This suggests that clone B1 is part of a multi-gene family in tomato. A putative N-glycosylation site (Asn-X-Ser/Thr; aa 105-107) was identified, which is also present in meri-5 and the genomic fragments, but not nasturtium XET. 
     The second clone obtained, termed clone tXET-B2 (abbreviated to “B2”), was larger than clone B1 but had no convenient restriction sites for subcloning, so several internal primers were used to complete DNA sequencing. The strategy used to determine the sequence of clone B2 is shown schematically in FIG.  4 . In FIG.  4 . E=EcoRI site, P=PstI site; (a) shows sequencing using vector primers, (b) and (c) shows sequencing with internal primers. A number of primers were employed, including:

     (Seq ID Nos. 24-30 respectively) 
     A deduced open reading frame of 287 amino acids was identified. The determined nucleotide sequence and deduced amino acid sequence of clone B2 are shown in FIG.  5 . FIG. 6 shows the cDNA sequence of clone B1 and deduced amino acid sequence thereof, in direct comparison with the deduced amino acid sequence for clone B2. (In FIG. 6, dots indicate identical amino acids, and the arrow indicates the predicted signal peptide cleavage site.) The predicted signal peptide for clone B2 was 2 amino acids shorter than that of clone B1, leaving a mature polypeptide of 269 amino acids. A putative N-glycosylation site was found in the same position as for clone B1. Sixteen amino acid differences between the predicted mature polypeptides of clones 8 and 16 were identified, 14 of which were conservative. 
     Hydrophobic Cluster Analysis (HCA, as described by Gaboriaud et al., 1987 FEBS Letters 224, 149-155 and Henrissat et al., 1988 Biochem. J. 255, 901-905) was performed to investigate possible conformational homology of the polypeptide encoded by clone B1 with other known proteins. 
     HCA plots were produced from the deduced amino acid sequences of nasturtium XET, meri-5 and tomato clone B1 using WordPerfect™ 5.1 macros, using a modified 2D representation of an α-helix (Henrissat et al. cited above). Hydrophobic clusters were encircled by hand, aligned manually and HCA homology scores calculated. 
     Similar folding was predicted for all three proteins on the basis of (a) “continuous presence of conserved clusters” throughout most of the length of the sequence and (b) overall HCA homology scores for all three comparisons being more than 75% (meri-5 v. tomato XET clone B1, 86%; nasturtium XET v. tomato XET clone B1, 80%; meri-5 v. nasturtium XET, 78%). 
     This supports data from primary sequence homology and secondary structure predictions (Kyte &amp; Doolittle 1982, J Mol Biol 157, 105-132) which suggest that these three proteins are likely to have broadly similar folding and therefore similar function, whilst differing in detail. 
     It was decided to attempt to express clone B2 in  E. coli.  This is described below in Example 2. 
     Example 2 
     Manipulation of Clone B2 for Expression in  E. coli    
     A BamHI recognition sequence was introduced close to the N-terminal coding sequence of the putative mature protein by PCR, using a mutagenic primer (16-1 B: CCCTT GGATCC GCTATAATT Seq ID No. 31) and a pBluescript primer (T3; Stratagene). Reaction conditions were: 1 ng XET clone B2 in pBluescript SK+, 0.4 mM each of dATP, dCTP, dGTP and dTTP, 25 pmols of each primer, 1×VENT polymerase buffer and 0.25 units VENT DNA polymerase (New England Biolabs Inc.). Thermal cvcling was 2 minutes at 93° C., 25 cycles of 1 minute at 93° C., 30 seconds at 55° C. and 1 minute at 72° C. 
     Over-expression of Recombinant Tomato XET in  E. coli    
     Expression of tomato XET in  E. coli  was achieved using the QIAGEN QIAexpress™ system. A BamHI-HindIII fragment of the mutagenised PCR product was ligated into the expression vector pQE30 and transformed into  E. coli  M15 cells containing the pREP4 repression plasmid. The expression vector allows incorporation of a 6×histidine tagged N-terminal which has high affinity for Ni-NTA (Ni-NTA is nickel-nitrilo tri-acetic acid) resin provided by QIAGEN. Cells were grown in Lennox broth containing appropriate antibiotics and induced with 2 mM IPTG when the optical density of the culture at 600 nm was 0.7-0.8. Growth was then allowed to continue for 3-5 hours. For analysis, cells were pelleted from 0.5 ml of the culture, boiled in sample buffer (Laemmli 1970 Nature 227, 680-685) and run on SDS-polyacrylamide gels (10%); separated proteins were stained in Coomassie blue. Localisation of tagged proteins was established as in protocol 4 of “The QIAexpressionist” 2nd edition (1992; QIAGEN Inc.). 
     Recombinant Tomato XET Protein Purification and Refolding 
     Recombinant tomato XET was purified under denaturing conditions on Ni-NTA resin as described in “The QIAexpressionist” protocol 7, except that after the final wash, the column with bound protein was equilibrated in 6M urea, 0.5M NaCl, 20% glycerol, 40 mM Tris-HCl pH7.4. An FPLC-mediated 6M-1M urea gradient (24 ml at a rate of 0.25 ml/min) in the above solution was then used to refold the bound protein, which was eluted in 10 ml 1M urea, 0.5M NaCl, 20% glycerol, 40 mM Tris-HCl pH7.4, 250 mM imidazole. 
     Assays for XET Activity 
       3 H-labelled XG oligosaccharides were obtained from S C Fry, (University of Edinburgh) and their incorporation into polymeric XG assayed as described by Fry et al. (1992 Biochem. J. 261, 9489-9494). Protein concentration was estimated using a kit supplied by BioRad. 
     N-terminal Amino Acid Sequencing 
     Purified recombinant proteins were subjected to electrophoresis as above, using high quality reagents. They were then electroblotted (0.5 A, 2 hours) onto Problott™ membrane (a derivatised PVDF material, obtained from ABI) and stained in 1% Coomassie Brilliant Blue, 50% methanol. The blotted protein was subjected to sequential Edman degradation on an ABI gas phase sequencer model 740, with pulse liquid update, as described by Cottingham et al. (1988 Biochim. Biophys. Acta 956, 201-207). 
     Expression and Characterisation of Recombinant Tomato XET 
     Tomato XET was expressed in  E. coli  with an N-terminal 6×His tag to facilitate purification. A tagged protein of the predicted molecular weight (32 kDa) was found in the insoluble fraction; phase contrast microscopy of the expressing culture showed strongly refracting bodies in each cell, suggesting the presence of insoluble inclusion bodies (data not shown). Following large-scale purification under denaturing conditions, the tagged protein was subjected to N-terminal amino acid sequencing. The resulting sequence (MRGSHHHHHHGSADNFYQDA Seq ID No. 32) confirmed both the identity of the protein as recombinant tomato XET, and the presence of the N-terminal 6×His tag. 
     Recombinant tomato XET was refolded whilst bound to the Ni-NTA agarose resin, by a reverse urea gradient. Following elution from the column, 15 μl was assayed for incorporation of  3 H-XG oligosaccharides (XGOs) into polymeric XG: approximately 400 Bq of  3 H-XGOs were incorporated per kBq provided, per hour, per μg protein. Following dialysis against 0.5M NaCl, 50 mM Tris-HCl pH7.2, 20% glycerol, specific activity increased to approximately 700 Bq/kBq hour μg. 
     Clone B2 was thus over-expressed in  E. coli  with the apparent N-terminal signal peptide replaced with a 6×histidine tag which facilitated purification. Following purification and refolding, the recombinant protein was able to catalyse incorporation of radiolabelled XG oligosaccharides into polymeric XG, confirming it as an XET. The specific activity of the refolded XET is relatively low; a crude stem extract from a growing tomato plant has an XET specific activity of about 100 Bq/kBq hour μg, compared to 700 Bq/kBq μg for refolded XET. Since the recombinant protein is greater than 90% pure, this is presumably due to most of the protein not being correctly refolded. 
     Unlike nasturtium seed XET, a putative N-glycosylation site is present in both clones&#39; amino acid sequences. It is interesting to note that, recombinant expression in  E. coli , which does not glycosylate proteins, resulted in active XET. This shows that the glycosylation is not necessary for XET activity in vitro, raising questions about its role in vivo. The lack of glycosylation in nasturtium seed XET may reflect its specialist role in storage reserve mobilization. 
     Evidence for the function of XET in plants is rapidly accumulating. The hypothesis that XET plays a role in plant growth is supported by its correlation with growth along the length of pea stems (Fry et al, 1992 Biochem. J. 282, 821-828) and in maize roots (Pritchard et al, 1993 J. Exp. Bot. 44, 1281-1289). It is thought to act by loosening the cell wall to permit cell expansion. 
     XET is also likely to be involved in fruit ripening, as suggested by its changing levels in fruits as diverse as tomato, pear (unpublished observations of the inventors) and kiwi (Fry 1993 Current Biology, 3 (no. 6), 355-357). Here XET may improve access of other enzymes to the tightly packed networks of the cell wall. This would be supported by the small, compact nature of XET (Edwards et al., 1986 J. Biol. Chem. 261, 9489-9494). Alternatively, XET may be involved (possibly in conjunction with other cell wall hydrolases) in the depolymerisation of xyloglucan which occurs during fruit ripening. 
     Example 3 
     In addition to the recombinant DNA work described above, attempts were made to isolate and purify a polypeptide having XET activity from tomato plants. 
     Step 1: Assay for Activity of XET 
     XET activity in various crude tomato fruit extracts was measured by incorporation of  3 H-labelled xyloglucan oligosaccharides into xyloglucan polymer. This assay measures transglycosylase activity. Each assay contained the following components: 10 μl 0.2M Na-Mes, pH 6.0 (Na-Mes is Na 2-[N-Morpholino] ethanesulphonic acid), 10 μl 8 mg/ml xyloglucan, and 5 μl [ 3 H] XGO (0.7 KBq). 
     Assays were incubated at 25° C. for 1 hour, and stopped by addition of 100 μl 20% formic acid. The assay mixture was then spotted onto a 5×5 cm disc of cellulose filter paper (Whatman 3MM Chromatography paper). It has been established that xyloglucan polymer (whether labelled or unlabelled with [ 3 H]XGO) will bind to the cellulose filter, whereas [ 3 H]XGO oligosaccharides will not. The filters were allowed to dry and unincorporated [ 3 H]XGO was removed by washing under running tap water for 30 min. The filters were dried again at 60° C., then rolled, loaded face outwards, into a cylinder and placed in a 22 ml scintillation vial. Scintillant (2 ml of Betamax ES) was added and the filters counted for  3 H. This assay is essentially as described by Fry et al. (1992), cited above. 
     Step 2: Extraction of XET from Tomato Pericarp 
     A variety of extraction buffers were used and their effectiveness assessed. It was found that XET was efficiently extracted by 0.1 M sodium phosphate buffer, pH 7.2. It was also found that retention of XET activity was highly dependent on ionic strength, and activity was lost if the ionic strength of chromatography buffer etc. was less than 0.2M. 
     Step 3: Choice of Starting Material for Purification 
     Crude extracts were made (in 0.1 M sodium phosphate buffer, pH 7.2) from tomato pericarp ( Lycopersicum esculentum , var. Moneymaker) tissues taken from all stages of growth and ripening. It was consistently found (from several experiments) that small green fruit (i.e. less than 35 mm in diameter) had the highest XET activity, whether expressed as total or specific activity. Therefore the pericarp of small green fruit was used as the starting material for purification. 
     Step 4: Ammonium Sulphate Precipitation 
     Pericarp tissue (100 g) from small green fruit of less than 35 mm in diameter was harvested, frozen in liquid nitrogen, and stored at −20° C. or −70° C.. The tissue was homogenised in 1 g:1.5 vol 0.1 M sodium phosphate, pH 7.2 with 1.0% (w/v) insoluble PVP (polyvinyl pyrrolidone) in a blender. The homogenate was stirred for 1 hour at 4° C. to allow diffusion of cell wall enzymes. Insoluble material was removed by centrifugation at 20,000 g, 30 minutes, 4° C. in the SS34 rotor of the Sorvall RC5B centrifuge. The supernatant was passed through glasswool, and brought to 90% ammonium sulphate saturation by addition of solid ammonium sulphate (60.3 g/100 ml). The mixture was stirred for 40 min at 4° C., and the precipitated proteins collected by centrifugation (38,000 g, 30 minutes, 4° C.). The ammonium sulphate precipitated proteins were stored at −20° C. without resuspension. 
     Step 5: S-sepharose Cation Exchange Chromatography 
     0-90% ammonium sulphate precipitated proteins were resuspended in 10 ml 50 mM sodium acetate buffer, pH 5.3 with 0.2 M NaCl (Buffer A) containing 1 mM EDTA, 20 μg/ml chymostatin, 1 mM PMSF. The resuspended pellet was dialysed for 2 hours against 2.5 l of Buffer A using 3,500 M-cut off dialysis tubing. The sample was diluted with 50 mM sodium acetate buffer pH 5.3, 1 mM EDTA to bring the conductivity down to a suitable value for loading onto the S-Sepharose column. The sample was centrifuged at 38,000 g for 15 minutes, 4° C., then loaded onto a 7 ml S-Sepharose Fast Flow column (Pharmacia) equilibrated in Buffer A. The column was washed with Buffer A (flow rate 1 ml/minute) until all unbound proteins were removed. Bound proteins were eluted with a 0-100% gradient of Buffer B (as Buffer A, but with 1 M NaCl) over 10 column volumes. Fractions (2 ml) were collected and assayed for XET activity. 
     Step 6: Concanavalin A Affinity Chromatography 
     Fractions from S-sepharose ion exchange chromatography with high XET activity were pooled and stored at −20° C. Prior to concanavalin chromatography, the fractions were brought to 1 mM MgCl 2  and MnCl 2 . The S-Sepharose pool was centrifuged and the supernatant loaded onto a Concavalin-A column equilibrated in 50 mM sodium acetate buffer pH 5.7 containing 0.2 M NaCl, 1 mM MgCl 2 , 1 mM CaCl 2  and 1 mM MnCl 2  (Buffer C). Bound proteins were eluted from the column with a single step elution with Buffer D (as Buffer C plus 0.5 methyl α-D-mannopyranoside). Fractions collected were assayed for XET activity. 
     Step 7: N-terminal Amino Acid Sequencing 
     Samples from the Concanavalin A column with high XET activity were separated according to apparent molecular weight on a 15% SDS polyacrylamide gel. After electrophoresis, proteins were transferred onto the Problott™ membrane (transfer buffer: 10 mM CAPS pH 11 in 10% methanol). The Problott™ membrane was stained in 0.1% Coomassie Brilliant Blue R250 in 1% acetic acid, 40% methanol and destained in 50% methanol. A single band (i.e. the protein had been successfully purified to homogeneity) of approximate M r 36,000 was visible; this was excised and subjected to N-terminal amino acid sequencing on an ABI model 475 protein sequencer. The sequence determined (Seq ID No. 33) was: GYPRRPVDVPFWKNY. The level of the sequence was consistent with the intensity of the stained protein band. 
     In another aspect therefore, the invention provides a substantially pure polypeptide with xyloglucan endotransglycosylase (XET) activity with an apparent molecular weight of 36 kDa, as judged by SDS-PAGE. 
     Preferably the enzyme is obtainable from tomato plants, most preferably from the pericarp of green tomato fruit, and preferably has substantially the N-terminal amino acid sequence (Seq ID No.33) GYPRRPVDVPFWKNY. 
     The enzyme is preferably purified by one or more of ammonium sulphate precipitation, ion exchange chromatography and/or concanavalin A affinity chromatography. 
     Example 4 
     Expression of XET in Tomato 
     The XET assay described above has been used to monitor XET activity throughout the tomato plant (var. Moneymaker). Extracts (0.2M phosphate) were prepared from root, leaf and petiole segments isolated from different parts of the growing plant and fruit at four stages of development and three stages of ripening. Highest XET activity was recorded in extracts prepared from petioles isolated from the top of the growing plant and developing (small green) fruit, consistent with XETs involvement in plant growth. 
     Total RNA was extracted from different parts of the tomato plant using a Qiagen extraction procedure. tXET-B1 (tomato XET clone B1) transcript levels were determined by RNAse protection analysis. An antisense tXET-B1 specific probe was synthesised by incubating HindIII linearised ptXET-B1 plasmid with 1 μl T3 RNA polymerase in the presence of 0.5 mM rATP/rGTP/rCTP, 5 nM UTP, 50 μCi 32 P-UTP (800 Ci/mmol), 1 μl RNase inhibitor and 2 μl reaction buffer (Ambion probe synthesis kit) in a final reaction volume of 20 μl for 1 hour at 25° C. Following DNase digestion and phenol/chloroform extraction, probe was recovered by ethanol precipitation. 10 5  cpm labelled probe was incubated with 5 μg total RNA and RNase protection analysis carried out using an RPAII kit supplied by Ambion. Protected probe was quantified by denaturing gel electrophoresis followed by analysis on a Molecular Dynamics PhosphorImager. Highest levels of tXET-B1 transcripts were detected in fruit pericarp, with levels in increasing through ripening and peaking in pink fruit. Maximum levels in stem (equivalent to levels seen in mature green fruit) were found approximately 10 cm from the top of a 30 cm plant. Lower levels of tXET-B1 transcript were detected in leaf with negligible levels in root. The differences in the patterns of activity and transcript level suggest either that total XET activity is encoded by a set of differentially expressed genes or that selective isolation of isoforms is occurring at 0.2M phosphate. The pattern of expression of tXET-B1 suggests that this isoform may be involved in fruit ripening. 
     Example 5 
     Reduction of XET Enzyme Levels in Transgenic Tomato Plants 
     A constitutive 2′ mannopine synthase promoter was recovered on a BglII fragment from the plasmid pSLJ2′Lnos, and ligated into the plasmid ptXET-B1. (pSLJ2′Lnos was derived from pSLJ1006 [Jones et al., 1992 transgenic Research 1, 285-297] by replacing the DNA sequence encoding a β-glucuronidase enzyme with a polylinker sequence). This placed the tXET-B1 coding sequence in the antisense orientation with respect to, and downstream of, the 2′ promoter (FIG.  7 ). An Xba - Sst fragment containing the promoter and 798 bp (nucleotides 187 to 984) of tXET-B1 sequence was then cloned into the plant transformation vector, pGPTV-kan (Becker D. et al., 1992, Plant Molecular Biology 20, 1195-1197 and FIG.  8 ). The resultant plasmid, pGPTV-kan-2′tXET-B1 was used to transform Agrobacterium LBA4404 and the recombinant agrobacterium strain used to infect cotyledonary segments of tomato (variety Moneymaker). Transformed plants were selectively regenerated in the presence of kanamycin. The presence of the transferred DNA was confirmed by PCR amplification of a DNA segment between the primers NPTIIb (5′ ATCGGGAGCGGCGATACCGTA 3′, Seq ID No. 34) and 8-HS (see above). XET activity was monitored in extracts prepared from pink fruit (15 plants) by the method described above. Levels were reduced by up to approximately 80% in plants transformed with an antisense tXET construct.
