ISOLATION AND PROPERTIES OF LECTINS FROM CELL WALLS OF WHEAT SEEDLINGS
INFECTED BY Fusarium graminearum AND TREATED BY SALICYLIC ACID
Plant Breeding and Genetic Institute - National Center of Seed and Cultivar Study, National Academy of Agrarian Sciences of Ukraine, Odessa;
Lectins from cell walls of wheat seedlings in normal conditions and infected by Fusarium sp. and treated by salicylic acid were isolated by the methods of gel-filtration, affinity chromatography and isoelectric focusing, their biochemical properties were studied. It is shown that isolated preparations of lectins suppressed the development of colonies of fungus Fusarium graminearum. A conclusion was made on the possibility of employment of isolated lectins in the molecular-breeding programs on raising wheat resistance towards fusariosis.
Key words: Triticum aestivum L., lectins, purification and properties, fusariosis, salicylic acid.
