In the conditions of the Republic of Belarus there was studied expression of PR-genes of two potato (Solanum tuberosum) varieties with different degree of resistance to bacterial soft rot. In course of the study there were used bacteria Pectobacterium carotovorum 2A (Pc), Pectobacterium atrosepticum 21 A (Pa), Dickeya dadantii ENA 49 (Dd). In course of the study there was analysed relative quantity of copies of messenger RNA potato genes PR-3, PR-5t and PR-10 in tubers and leaves of the analysed potato varieties Skarb and Vesnyanka. There were presented results of the relative quality of copies of messenger RNA of the studied potato varieties after their bacterial contamination with Pectobacterium carotovorum 2A, Pectobacterium atrosepticum 21 A and Dickeya dadantii ENA 49. The experiments revealed the different degree induction of PR-3, PR-5t and PR-10 genes in potato tissues in response to infection by pectolytic strains of bacteria. It was observed a correlation between the degree of induction of the PR-5t gene and resistance of the cultivars to soft rot.
