Abstract

The effect of 1-methylcyclopropene (1-MCP), which inhibits the reception of ethylene, on the following has been studied: hydrogen peroxide generation, oxalate oxidase activity, peroxidase activity, catalase activity, and lignin accumulation in infected leaves of soft spring wheat (Triticum aestivum L.) cultivars that differ in their resistance to the leaf blotch disease, caused by the hemibiotrophic fungus Septoria nodorum Berk. A decrease in the development of leaf blotch in wheat leaves under the influence of 1-MCP was, on one hand, followed by an inhibition of catalase activity; on the other hand, it was accompanied by an increase in oxalate oxidase and peroxidase activity, as well as an accumulation of H2O2 in tissues and lignin in the infected zone. The role of the ethylene reception system in the defense response of plants to infection with a hemibiotrophic pathogen, that causes leaf blotch disease, is discussed.
