诱饵模式——病原菌致病的全新机制

XEG1属于GH12家族糖基水解酶,能降解植物细胞壁,是疫病菌攻击植物的关键＂武器＂。植物在利用抑制蛋白GIP1对XEG1的防卫过程中,疫霉菌能分泌失去酶活性的XEG1突变体——XLP1作为＂诱饵＂吸引抑制蛋白,掩护XEG1对植物的攻击。

XEGl is a Ph, ytophthora sojae glycoside hydrolase 12 protein which function as a major virulence factor during infetion. Soybean produces an apoplastic glucanase inhibilor protein （ GIP1 ） that biMs to XEGI to bloek its contribution to virulence. P.sojae however, secretes a paralogous XEGl-like pntein（ XLPI ）that lacks enzyme activity but binds Io GIP1 more tightly than XEGI, thus freeing XEG1 to support P. sojae infection.
