摘要:
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。
Abstract:
XEG1 is a Phytophthora sojae glycoside hydrolase 12 protein which function as a major virulence factor during infection. Soybean produces an apoplastic glucanase inhibitor protein (GIP1) that binds to XEG1 to block its contribution to virulence. P.sojae however, secretes a paralogous XEG1-like protein(XLP1) that lacks enzyme activity but binds to GIP1 more tightly than XEG1, thus freeing XEG1 to support P.sojae infection.
