摘要：
Pectobacterium carotovorum subsp. carotovorum (Pcc) is one of the most destructive pathogens causing stem rot disease on tomato. In this study, expression profiling of pathogenesis-related gene 1 (PR-1), pathogenesis-related gene 2 (PR-2), phenylalanine ammonia-lyase (PAL) and catalase (CAT) in a partially resistant (Sun) and a susceptible (Early orbano) tomato cultivar in response to Pcc were compared. Our results showed more expression of PR-2, PAL and CAT in the partially resistant cultivar than the susceptible cultivar. On the other hand, no significant difference was found in expression of PR-1 between the both cultivars. These findings suggest the involvement of PR-2, PAL and CAT in defense responses of tomato against Pcc that might be considered in plant breeding programs.
