The present invention relates to anti-microbial proteins isolatable from sugar beet

According to the present invention there is provided anti-microbial protein comprising a peptide having the sequence -Gln7Cys-AA ₂ -Pro/Ile-Asn/Thr/Leu-AA< _i -AA ₆ -Cys-Cys-Ala/Asn- Gly Lys-AA ₁₁ -AA _I2 -AA _π -AA| ₄ -AA„-, with the proviso that AA ₂ and AA ₁₄ are not cysteine, and that AA ₄ is Leu when AA, is Cys The skilled man will recognize that the abbreviation AA _X means one of the 20 commonly occurring amino acids

An anti-microbidl protein includes a protein (alone or in combination with another material) which is toxic or growth inhibitory under any circumstances to any micro-organism, including bacteria, (most particularly Gram positive bacteria), viruses and particularly fungi Such anti¬ microbial proteins include those that exhibit anti-microbial activity upon contact with a micro¬ organism and those that are anti-microbial as a consequence of assimilation or respiration thereof

According to the present invention there is provided an anti-microbial protein having the sequence depicted in any one of SEQ ID Nos 3, 5 or 6

Also included is an isoform of an anti-microbial protein having SEQ ID No 3 wherein Val

The invention still further includes pure protein which is substantially similar to any one of the above mentioned proteins

By "substantially similar" is meant pure proteins comprising an amino acid sequence which ist at least 95% similar to the peptide sequence given above (also as defined in Claim 1) and/or pure proteins having an amino acid sequence which is at least 65% similar, preferably 75% similar, more preferred 85% similar, particularly preferred 95% similar to the sequence of the proteins depicted in SEQ ID Nos 3, 5 or 6 below In the context of the present

invention, two amino acid sequences with a given percentage similarity to each other have at least that percentage of identical or conservatively replaced amino acid residues in a like position when aligned optimally allowing for up to 2 gaps with the proviso that in respect of each gap a total not more than 2 amino acid residues is affected.

For the purpose of the present invention conservative replacements may be made between amino acids within the following groups:

(i) Serine and Threonine;

(ii) Glutamic acid and Aspartic acid;

(iii) Arginine and Lysine;

(iv) Asparagine and Glutamine;

(v) Isoleucine, Leucine, Valine and Methionine;

(vi) Phenylalanine, Tyrosine and Tryptophan

(vii) Alanine and Glycine

The invention still further includes pure proteins which are at least 90% identical to the anti¬ microbial proteins according to the invention, as well as pure proteins which have at least 90% of the specific activity thereof. For the purposes of the present application, specific activity is a measurement of the amount of growth or replication inhibition produced by a specified quantity of the protein on a specified quantity of a specified micro-organism.

The invention still further includes said pure proteins in combination with at least one protein selected from the group consisting of those depicted in SEQ ID Nos. 7 to 12 and 14. Such combined proteins may be further combined with one or more of the known "pathogenesis- related proteins". Infection of plants with fungal or viral pathogens may induce a systemic synthesis of about 10 families of homologous pathogenesis-related proteins (PR proteins) in vegetative tissues. Such PR-proteins have been classified into 5 groups. The PR-2, PR-3 and PR-5 proteins are beta- l ,3-glucanase, chitinases and thaumatin-like proteins respectively. Specific functions have not been assigned to the PR- 1 and PR-4 groups of proteins. The PR-4 proteins are similar to C-terminal domains of prohevein and the putative wound-induced WIN proteins of potato, thus lacking the N-terminal hevein domain. It is particularly preferred that

the proteins according to the invention are combined with one or more proteins which are the basic counter parts of the P-R 4 group of proteins, meaning the basic counter part of proteins similar to the C-terminal domains of prohevein and the putative wound-induced WIN proteins of potato. It is particularly preferred that the basic counter-part of the said pathogenesis- related proteins is a chitin-binding WIN protein, in particular that produced by barley grain or stressed barley leaves.

The invention still further includes recombinant DNA comprising a sequence encoding a protein having the amino acid sequence of the above disclosed anti-microbial proteins. In particular the DNA may encode at least one of the proteins the sequences of which are depicted in SEQ ID Nos. 3, 5 and 6, optionally in addition to at least one of the proteins the sequences of which are depicted in SEQ ID Nos. 7 to 12 and 14. Preferably the sequence encoding a protein having the amino acid sequence depicted in SEQ ID No. 3, 5 or 6 has the cDNA sequence depicted in SEQ ID No. 1 (for the protein with SEQ ID No. 6, corresponding to IWF5), in SEQ ID No. 2 (for the protein with SEQ ID No. 3, corresponding to IWF6) or in SEQ ID No. 4 (for the protein with SEQ ID No. 5, corresponding to IWF7). The recombinant DNA may further encode a protein having herbicide resistance, plant growth- promoting, anti-fungal, anti bacterial, anti-viral and or anti-nematode properties. In the case that the DNA is to be introduced into a heterologous organism it may be modified to remove known mRNA instability motifs (such as AT-rich regions) and polyadenylation signals (if any arc present), and/or codons which are preferred by the organism into which the recombinant DNA is to be inserted may be used so that expression of the thus modified DNA in the said organism yields substantially similar protein to that obtained by expression of the unmodified recombinant DNA in the organism in which the anti-microbial protein according to the invention is endogenous.

The invention still further includes recombinant DNA which is "similar" to that mentioned above. By "similar DNA" is meant a sequence which is complementary to a test sequence which is capable of hybridizing to the inventive recombinant sequence. When the test and inventive sequences are double stranded the nucleic acid constituting the test sequence preferably has a TM within 20°C of that of the inventive sequence. In the case that the test

and inventive sequences are mixed together and denatured simultaneously, the TM values of the sequences are preferably within 10°C of each other. More preferably the hybridization is performed under stringent conditions, with either the test or inventive DNA preferably being supported. Thus either a denatured test or inventive sequence is preferably first bound to a support and hybridization is effected for a specified period of time at a temperature of between 50 and 70°C in double strength citrate buffered saline (SSC) containing 0.1 %SDS followed by rinsing of the support at the same temperature but with a buffer having a reduced SSC concentration Depending upon the degree of stringency required, and thus the degree of similarity of the sequences, at a particular temperature, - such as 60°C, for example - such reduced concentration buffers are typically single strength SSC containing 0 1%SDS, half strength SSC containing 0 1 %SDS and one tenth strength SSC containing 0.1%SDS Sequences having the greatest degree of similarity are those the hybridization of which is least affected by washing in buffers of reduced concentration. It is most preferred that the test and inventive sequences are so similar that the hybridization between them is substantially unaffected by washing or incubation in one tenth strength sodium citrate buffer containing 0 1 %SDS

The invention still further includes a DNA sequence which is complementary to one which hybridizes under stringent conditions with the recombinant DNA according to the invention

Also included in the present mvention is a vector which contains the above disclosed DNA which is expressible in plants and linked to a plant operable promoter and terminator, plants transformed with such DNA, the progeny of such plants which contain the DNA stably incoφorated and hereditable in a Mende an manner, and/or the seeds of such plants and such progeny The transformed plants are made by known methods and include regeneration of plant cells or protoplasts transformed with the DNA of the invention according to a variety of known methods (Agrobacteπum Ti and Ri plasmids, electroporation, micro-injection, micro-projectile gun etc) The transformed cell may in suitable cases be regenerated into whole plants in which the nuclear material is stably incoφorated into the genome. Both monocot and dicot plants may be obtained in this way Examples of transformed plants according to the present invention include: fruits, including tomatoes, mangoes, peaches,

apples, pears, strawberries, bananas, and melons; field cops such as canola, sunflower, tobacco, sugar beet, small grain cereals such as wheat, barley and rice, maize and cotton, and vegetables such as potato, carrot, lettuce, cabbage and onion. The preferred plants are sugar beet and maize.

The invention still further includes protein derived from expression of the said DNA, and anti-microbial protein produced by expression of the recombinant DNA within plants transformed therewith.

The invention still further includes an anti-microbial composition containing one or more of the proteins according to the invention; a process for combatting fungi which comprises exposing them to such proteins, and an extraction process for obtaining anti-microbial proteins from organic material containing them comprising submitting the material - preferably in the form of a micro-organism - to maceration and solvent extraction. It will be appreciated that the anti-microbial protein exhibits little, if any, anti-microbial effect on the micro-organism which is the source of the organic material referred to in the previous sentence

Induction of resistance

Six-week old plants of sugar beet (Beta vulgaris L., cv. Monova, Danisco Seed) are treated four times with 25 ppm 2,6-dichloroisonicotinic acid (INA) with a two-day interval. The INA, suspended in 0.05% Tween 20, is applied by spraying the adaxial leaf surface to the point of saturation. Two days after the final treatment, intercellular washing fluid (IWF) is isolated as described below. Intercellular washing fluid isolated from leaves not subjected to INA also contains proteins according to the present invention.

Isolation of Intercellular Washing Fluid

IWF is isolated from 500-700 gram sugar beet leaves by submerging them in 20mM HAc (pH 4.5). The thus submerged leaves are then placed in an exicator and vacuum infiltrated for 5 min at 4 ton ^* (max). Following air-drying of the leaf surface, the IWF is collected by centrifugation at 500g for 15 min in 500 ml centrifuge tubes.

Cation exchange chromatography

The thus obtained IWF is fractionated by cation exchange chromatography on a 10 ml CM- Sepharose column (Pharmacia LKB) pre-equilibrated in starting buffer (20mM HAc (pH 4.5)). The fractionation is performed at 4°C at a flow rate of 25 ml/h. Fractions of 3 ml are collected. Proteins not bound to the column are removed by extensive washing of the column with starting buffer. Bound proteins are eluted by applying to the column further starting buffer comprising stepwise increased salt concentrations: viz, 0.1 M NaCl, 0.3 M NAC1 and 0.5 M NaCl. The absorbance at 280nm of the eluate is measured, and fractions judged to comprise protein are tested for their anti-fungal activity against C. beticola using the microtiter plate bioassay described previously (PCT Patent Application No. PCT DK92/00108, Publication No. WO 92/17591 , now assigned to Sandoz LTD).

A typical elution profile is shown in Fig. 1. The eluates resulting from application to the column of starting buffer comprising the 0.3M NaCl is further purified as described below.

Purification of antifungal proteins in the 0.3 M NaCl eluate from the CM-Sepharose. FPLC Chromatography

The 0.3M NaCl protein fraction is desalted by overnight dialysis (MW cut off: 1 kDa) against 20mM HAc (pH 4 5) at 4°C. Betaine is added at a concentration of 5% (w/v) to the thus dialysed protein fraction. Four ml of the resulting solution is then fractionated by cation exchange fast protein liquid chromatography (FPLC) using a Mono S HR 5/5 column ( Pharmacia LKB ) equilibrated in 20 mM HAc (pH 4.5) containing 5% (w/v) betaine (A- buffer) Bound proteins are eluted with a linear salt gradient from 0 to 0.3 M NaCl in 30 l of the A-buffer followed by a step elution with 1.0 M NaCl in the same buffer. Flow rate is 1 ml/min.

Figure 2 shows that the 0.3M NaCl fraction contains a number of distinct proteins, the quantitatively most significant of which are designated as peaks 1-5. Strong anti-fungal activity is associated with the proteins represented by peaks 4 and 5. When separated by SDS- PAGE using the Phast System (Pharmacia LKB), silver stained 10-15% gradient Phast gels or High Density gels (Pharmacia LKB) reveal that each of the peaks 4 and 5 contains about

10 different proteins.

Reverse Phase HPLC

Protein peaks 4 and 5 (depicted in Figure 2) from the Mono S column is further purified by reverse phase (RP-) HPLC on a Vydac C silica column (The Separations Group. CA, USA). The solvent system is A: 0.1% TFA in water and B: 0.1% TFA in acetonitrile. Proteins are eluted with a linear gradient of 5 to 45% of the B-buffer applied in 18 min after sample loading followed by 60% B-buffer in 2 min. Flow rate is 0.7 ml/min. Protein is detected by monitoring the absorbance of the eluate at 214 and 280nm. Discrete protein peaks are collected and lyophilized. The thus lyophilized proteins are washed twice with water, re- lyophilized and subsequently resolved in lOmM Tris-HCl (pH 8.0), prior to analysis of purity and anti-fungal activity. The material represented by peak 4 is separated into 9- 10 distinct protein peaks (Fig. 3) on the RP-HPLC column. Peaks 4.3 and 4.4 comprise strong antifungal activity and are consequently re-chromatographed on the RP-C4 column (Figs. 4 and 5). A subsequent analysis by SDS-PAGE (silver staining) demonstrated that these two proteins had been purified to homogeneity (data not shown). Furthermore, the N-terminal amino acid sequencing confirmed the presence of only one protein in each peak. Peak 4.3 and 4.4 are designated IWF6 and IWF5, respectively. The material represented by peak 5 in Figure 2 is separated into 8- 10 different protein peaks following RP-HPLC purification (Fig. 6). Of these, peak 5.4 comprised strong antifungal activity. Following a 2nd round of RP-HPLC (Fig. 7), the protein was homogenous as confirmed by SDS-PAGE and amino acid sequencing. This protein is designated IWF7.

Antifungal activity

The proteins, either alone or in combination with WIN N (which is purified from barley grain or stressed barley leaf as described by Hejgaard et_al (FEBS Letters, 307, 389-392 (1992)), and or a protein having a sequence corresponding to at least one of those given in SEQ ID Nos. 7- 12 and 14, are incubated with spores of C. beticola. The assay mix (240ul) contains lOOul of potato dextrose broth (Difco), 40ul protein sample (or buffer control) in lOOmM Tris and 20mM NaCl (pH 8.0) as well as approximately 400 spores in lOOul water. The micro- titre plates are sealed with tape to avoid evaporation and contamination and subsequently

incubated at room temperature on an agitator operated at 200 φm The absorbance at 620nm is measured each day for 8 days and plotted for each concentration of protein vs time The protein designated as IWF 5 showed a strong growth inhibiting effect against C. beticola. At lOμg/well (40μg/ml) no fungal growth could be detected (Fig. 8) and at 4μg/well the growth was markedly delayed and strongly inhibited (Fig 9) The protein designated as IWF6 also shows a strong growth inhibiting effect against C beticola The level of activity is comparable to that of IWF5, giving almost complete growth inhibition at - 5μg/well (Fig 10) Moreover, the protein designated as IWF7 also shows a strong growth inhibiting effect against C beticola At lOμg/well no fungal growth was detected (Fig 1 1) Furthermore, microscopical analyses indicated that the protein inhibited the germination of conidia Thus, IWF7 may effect spore germination as well as hyphal growth

Amino acid sequencing

The purified anti-fungal proteins corresponding to peak 4 4 in Figure 4, peak 4 3 in Figure 5 and peak 4 4 in Figure 7 which originate from the 0.3 M NaCl eluate from the CM- Sepharose column, (Figure 1 ), are carboxymethylated and subjected to RP-HPLC on a Vydac Cj column The solvent system is A 0 1 % TFA in water and B 0 1 % TFA in acetonitrile The proteins elute as single peaks with slightly different retention times The C-termmal sequences of the proteins are obtained by cleavage thereof with em/ø-R-proteinase and subsequent purification by RP-HPLC on a Vydac C, _g column

Production of transformed plants

The genes encoding proteins according to the invention are introduced into plants Based on gene specific primers, the coding regions of the genes encoding the proteins are synthesized from corresponding mRNA using PCR After addition of promoter and terminator sequences, the genes encoding the said proteins are introduced into a plant transformation vector. The vector may optionally include a gene encoding a WIN protein, such as that obtained from stressed barley leaf or barley grain, and/or a gene encoding one or more of the proteins depicted in SEQ ID Nos 4 to 9, and/or a gene encoding a chitinase and or a glucanase. One possible chitinase is the chitinase 4 described in PCT Patent Application No PCT/DK92/00I08 (Publication No WO 92/17591 ) Agrobacterium tumefaciens, for example, may be transformed with these vectors Plant cells are then treated with such transformed Agrobacterium. and the thus transformed plant cells are regenerated into whole plants, in which the new nuclear mateπal is stably incoφorated into the genome It will be appreciated, however, that the DNA encoding a protein according to the present invention, (or combination of such proteins), optionally further encoding other proteins, may be introduced into plant cells by other known methods, including use of a micro-projectile gun, electroporation, electro-transformation, and micro-injection etc, and that regeneration of transformed plant cells is carried out according to methods known to the skilled man, including treatment of the cells with cytokines where this is necessary or desirable in order to improve the regeneration frequency

Moreover, suitable micro-organisms (1 e. those in which the production of the present inventive proteins is not substantially toxic) may be transformed with a vector comprising the gene (or genes) encoding the protein so that the transformed micro-organisms produce such protein The micro-organisms may further comprise the genes encoding other proteins, such as a WIN protein and or a protein the sequence of which is depicted in one or more of SEQ IDs No 4-9 Furthermore, such other proteins may further comprise vaπous chitmases and/or glucanases One possible such other protein is the chitinase 4 as described in PCT Patent Application No PCT/DK92/00108 (Publication No WO 92/17591)

These micro-organisms may then be used to combat plant pathogens For example the transformed micro-organisms may be dried and sprayed onto infected plants or plants at risk of infection
