<p>Anti-microbial proteins isolated from sugar beet, wherein the anti-microbial proteins exclude chitinases and glucanases. Said proteins include a pure protein selected from those depicted in SEQ ID Nos 2, 5 and 8, or a functionally equivalent analogue thereof in which one or more amino acids have been added, substituted or removed without substantially reducing the protein's anti-microbial activity, or mixtures of such proteins or analogues. A synergistic anti-fungal effect is observed if at least one of the AX proteins is combined with a WIN protein. The invention also provides recombinant DNA comprising a sequence encoding a protein according to the invention, a vector comprising said DNA and transformed plants comprising said DNA. The invention further provides an anti-microbial composition containing one or more of the said proteins, and a process for combatting fungi or bacteria which comprises exposing them to said proteins or compositions.</p> |
