EFFECT OF β-1,3-GLUCANE ON THE STRUCTURAL AND FUNCTIONAL STATE OF PHOTOSYNTHETIC MEMBRANES OF TOMATO UNDER FUSARIUM WILT
Abstract
Infection of tomato plants with Fusarium oxysporum causes activation of lipid peroxidation processes (LPO) and significant changes in the structural and functional state of photosynthetic membranes, which is reflected in a decrease in Chl a, Chl a / Chl b ratio, disturbances in the absorption and utilization of light energy in PS II of photosynthesis. Pretreatment of plants with β-1,3-glucan contributes to the LPO stabilization and normalizes the course of photochemical processes in chloroplasts of infected leaves, which indicates the protective activity of the drug.
