报告题目:水稻先天免疫调控

报告摘要:

植物凭借自身的先天免疫系统对抗病原微生物。植物的先天免疫系统,从分子水平上,可以分为两个层次,PTI和ETI。微生物保守的化学组分,即病原相关的分子模式PAMP触发植物的PTI免疫反应,包括钙离子内流、活性氧产生等。植物免疫反应的持续激活对植物的生长发育不利,因此,植物PTI信号转导受到多层次的严密调控。报告人解析了水稻中一个单子叶植物特异的受体激酶SDS2介导的先天免疫信号转导途径及其负调控机制,阐明了SDS2在水稻先天免疫和细胞凋亡中的作用。

 

报告人简介:

TITLE:Regulation of Innate Immunity in Rice

ABSTRACT:

Plants employ two layers of innate immunity, PTI and ETI, to defend against pathogenic microorganisms. Conserved microbe structural chemicals, such flagellin and chitin, or PAMP, trigger PTI in plants. Plant PTI include Ca2+ influx, ROS burst, and many other responses. Plant PTI must be firmly regulated since over- or miss-activation leads to suppression of growth and/or cell death, the so-called growth-defense trade-off effect. The speaker established the signaling pathway from the monocots-specific RLK SDS2 to ROS burst in rice and illustrated the role of SDS2 in the control of innate immunity and cell death in rice.
