摘要
It has been reported that treatment with yeast cell wall extract (YCWE) induces PDF1 and PR-1 gene expression; these transcripts are important markers of plant disease resistance, though the detailed signaling mechanisms that induce these defense responses are still unknown. In this report, we found that YCWE treatment triggered rice cell suspension cultures to accumulate phenylalanine (Phe), cis-12-oxo-phytodienoic acid (OPDA), 12-hydroxyjasmonoyle isoleucine (12OHJA-Ile), and azelaic acid (AzA). YCWE treatment also reduced endogenous triacylglycerol (TG) content. The addition of
