植物通过细胞表面免疫受体和胞内免疫受体感受来源于病原微生物的分子,激活天然免疫,抵御病原物的侵染;而病原细菌通过向植物细胞分泌效应蛋白,干扰后者的细胞活动,增加其感染能力。大部分效应蛋白的生化功能和分子机制并不清楚,研究这些效应蛋白在宿主体内的靶蛋白和作用机制, Plants through the cell surface immune receptors and intracellular immune receptors to sense the molecules from pathogenic microorganisms, activate natural immunity, to resist the infection of pathogens; and pathogenic bacteria through the secretion of effector proteins to plant cells, interfere with the latter’s cell activity, Increase their ability to infect. The biochemical functions and molecular mechanisms of most effector proteins are not clear, and the target proteins and their mechanism of action of these effector proteins in the host are studied.
