- Abstract
Bacterial blight on cruciferous plants, caused by Pseudomonas cannabina pv. alisalensis (Pcal) inflicts serious damage in Japan. We previously demonstrated that acibenzolar-S-methyl (ASM), one of the plant activators, showed a protective effect on cabbage and Japanese radish against Pcal disease. However, the metabolic substances triggering ASM-induced systemic resistance remain unclear in cabbage and Japanese radish. Therefore, we here quantified ASM and its derivative, acibenzolar, after ASM treatment in a spatiotemporal manner. After ASM soil drench in cabbage, acibenzolar was detected in the root, stem, and leaf, but ASM was not detected in cabbage leaf. Moreover, after ASM leaf dip treatment in Japanese radish, acibenzolar was mainly detected in untreated leaves. These results suggest that acibenzolar is a metabolic substance that can migrate and induce ASM-induced systemic resistance in cabbage and Japanese radish.
