Comparison of the Transcriptional Activity of Protective Protein Genes in Different Wheat Cultivars Infected with Septoria nodorum Berk

摘要

A comparison was performed with respect to the transcriptional activity of protective protein genes (peroxidase TC 151917, oxalate oxidase AJ 556991.1, and proteinase inhibitor EU 293132.1) in five wheat cultivars (Omskaya 35 and 36, Simbirka, Bashkirskaya 26, and Kazakhstanskaya 10) infected with Septoria nodorum Berk, which causes septoria disease. The intensity of parasite development on leaves was assessed based on the areas of infectious sites in plant tissues. This value was minimal in cultivars Omskaya 35 and 36 and maximal in cultivars Simbirka and Kazakhstanskaya 10; cultivar Bashkirskaya 26 was at an intermediate position. Resistant cultivars had a higher degree of transcriptional activity of genes of anionic peroxidase, oxalate oxidase, and proteinase inhibitor during infection than sensitive cultivars. Our data demonstrate the prospects of using expression levels of the AJ 556991.1, TC 151917, and EU 293132.1 genes as markers for the selection of resistant wheat cultivars.
