Abstract

Effects of 50 μM salicylic acid (SA) and 0.1 μM jasmonic acid (JA) on the transcriptional activity of the genes encoding isoperoxidase (M21334) and PR-1 and PR-6 proteins during the development of potato (Solanum tuberosum L.) defense response to Phytophthora infestans (Mont.) de Bary were investigated. The considerable accumulation of transcripts of peroxidase M21334 gene occurred in infected plants treated with JA together with SA or after SA, but not in the case of SA after JA. A decrease of the area of lesions induced by P. infestans on potato leaves treated with these compounds is one of the indications of their stimulatory effects on plant immunity. The obtained data suggest that plant resistance to the late blight is regulated via systemic induced resistance where JA plays an important role as an intermediate on conditions of active regulatory participation of SA.
