Abstract

Elicitors induce accumulation of phytoalexins in plants1. Recently Yoshikawa2 concluded that biotic and abiotic elicitors act by different mechanisms. Thus a biotic elicitor, such as the cell walls of Phytophthora megasperma var. sojae, stimulated glyceollin synthesis in soybean cotyledons but had no significant effect on glyceollin degradation. In contrast, the abiotic elicitor HgCl2 had only a slight effect on the biosynthetic activity but strongly inhibited glyceollin degradation. Here we report results which are contrary to Yoshikawa's conclusion.
