Abstract

It was studied the effect of steroid phytohormone 24-epibrassinolide on the content and composition of complex oxylipins in flax leaves. The increase in content of linolipins, i.e. galactolipids containing divinyl ether residues, was observed in plants treated with the plant hormone as well as inoculated with Pectobacterium atrosepticum. The treatment of plants with phytohormone prior to their inoculation resulted in the significant accumulation of linolipins compared to other variants. These data revealed that brassinosteroids can participate in the processes of the formation of phytoimmunity through the regulation of divinyl ether synthase branch of lipoxygenase pathway.
