ROLE OF PLANT DEFENSINS IN COMPLEX SYSTEM OF PLANT PROTECTION (a review)

F.M. Komaletdinova

The properties of plant proteins — defensins, possessing fungicidal, antimicrobial and in-secticidal activity, were considered. The author discusses the structure, expression and localization in plant tissues of different classes of these proteins, varied in their action on pathogens and primary structure, the positioning of aminoacids, important for protective action, the supposed mechanism of action of transgenic plants with genes of plant defensins. The presented data suggest about defensins participation in system plant protection against biotic and abiotic stress.

Key words: antifungal peptides, plant defensins, defense responses.
