植物一生面临着非常复杂和严峻的生存环境。在与各种病原体作斗争的漫长进化过程中,植物逐渐形成了一系列高效复杂的先天性免疫和系统获得性免疫来抵御病原微生物的侵染。存在于大多数高等植物中的FLS2受体通过识别鞭毛蛋白高度保守N末端表位(Flg22)来提示细菌的入侵,从而发动免疫反应以消灭入侵的病原体。关于相关机制的研究将加强我们改进现有的粮食作物抗病性能从而达到提高产量的作用。清华大学柴继杰博士研究团队和中国科学院以及英国的研究人员合作,联合开展了深入研究,在上海同步辐射光 Plant life is faced with a very complex and harsh living environment. In the long evolutionary process of combating various pathogens, plants have evolved a series of highly sophisticated and sophisticated innate and system-acquired immunity against the intrusion of pathogenic microorganisms. The FLS2 receptor present in most higher plants prompts bacterial invasion by recognizing that the flagellin highly conserves the N-terminal epitope (Flg22), thereby initiating an immune response to destroy invading pathogens. Research on relevant mechanisms will strengthen our role in improving the disease resistance of existing food crops so as to increase yields.
