Biocidal proteins isolated from Mirabilis have been characterized. The proteins show a wide range of antifungal activity and are active against gram-positive bacteria. DNA encoding the proteins has been isolated and incorporated into vectors. Plants transformed with this DNA have been produced. The proteins find commercial application as antifungal or antibacterial agents; transformed plants will show increased disease-resistance.

Biocidal proteins

Antimicrobial proteins capable of isolation from seeds of Heuchera or Aesculus show a wide range of antifungal activity and some activity against Gram-positive bacteria. DNA encoding the proteins may be isolated and incorporated into vectors. Plants transformed with this DNA may be produced. The proteins find commercial application as antifungal or antibacterial agents; transformed plants will show increased disease-resistance.

Antimicrobial proteins

Biocidal proteins capable of isolation from seeds have been characterized. The proteins have an amino acid sequence containing the common cysteine/glycine domain of Chitin-binding Plant Proteins but show substantially better activity against pathogenic fungi, a higher ratio of basic amino acids to acidic amino acids, and/or antifungal activity which results in increased hyphal branching. Antimicrobial proteins isolated from Amaranthus, Capsicum, Briza and related species are provided. The proteins show a wide range of antifungal activity and are active against Gram-positive bacteria. DNA encoding the proteins may be isolated and incorporated into vectors. Plants may be transformed with this DNA. The proteins find agricultural or pharmaceutical application as antifungal or antibacterial agents. Transgenic plants expressing the protein will show increased disease resistance.

Biocidal proteins isolated from seeds have been characterised, in particular proteins isolated from members of the Brassicaceae, Compositae and Leguminosae families including Raphanus, Brassica, Sinapis, Arabidopsis, Dahlia, Cnicus, Lathyrus and Clitoria. The proteins show a wide range of antifungal activity and some are active against Gram-positive bacteria. All share a common amino acid sequence. DNA encoding the proteins has been isolated and incorporated into vectors. Plants transformed with this DNA may be produced. The proteins find commercial application as antifungal or antibacterial agents; transformed plants will show increased disease-resistance.
