Characterization of defensin-like proteins from Scots pine seedlings

V. A. Kovalyova, I. T. Gout, R. T. Gout

Two defensin-like proteins with molecular weight of 11.3 and 9.8 kDa were isolated from 7-day-old Scots pine seedlings (Pinus sylvestris L.) by the ion exchange chromatography on phosphocellulose. These proteins inhibited the growth of mycelium of the phytopathogenic fungus Fusarium oxysporum at concentration mkg/ml, and also caused the morphological changes of hyphae.

Key words: Scots pine, defensin, Fusarium oxysporum.
