Il'inskaia LI, Chalenko GI, Perekhod EA, Gerasimova NG, Ozeretskovskaia OL: [Effect of methyljasmononate on induction of late-blight resistance of potatoes using arachidonic acid]. Prikl Biokhim Mikrobiol. 2000 Mar-Apr;36(2):214-20.
Methyl ester of jasmonic acid (Me-JA) influences the induced resistance of potato tubers to late blight caused by Phytophthora infestans. Treatment of potato tuber disk surface with Me-JA solution or exposure to an atmosphere containing Me-JA vapors (10 (-6)-10 (-5) M) increased the rate of rishitin biosynthesis induced by arachidonic acid or P. infestans. Methyl jasmonate increased the sensitivity of potato tissue to arachidonic acid. As a result, in the presence of Me-JA, the protective properties of arachidonic acid were observed at lower concentrations than in the absence of Me-JA. In addition, Me-JA reduced the adverse effects of lipoxygenase inhibitors (salicylhydroxamic acid and esculetin) on the induced resistance of potato tubers to late blight. Therefore, the synergistic interaction of Me-JA and biogenic elicitors can be regarded as part of a mechanism of potato defense against diseases. |
