植物必须平衡来自微生物的有益(共生)和致病挑战,前者使植物和农业受益,后者造成疾病和经济损害。植物先天免疫描述了一套高度保守的防御机制,这些机制在感知与共生微生物和病原微生物相关的免疫信号以及随后下游激活保护植物的信号效应器网络方面发挥关键作用。一个有趣的问题是,先天免疫系统如何区分“朋友”和“敌人”。在这里,我们总结了最新的进展,我们了解的作用和光谱的先天免疫在识别和响应不同的微生物。此外,我们还综述了微生物操纵植物信号通路从而逃避免疫的一些策略,重点介绍了效应蛋白和微型RNAs(MiRNAs)的使用。此外,我们讨论了需要解决的潜在问题,以推动植物-微生物相互作用领域的发展。
Plants must balance both beneficial (symbiotic) and pathogenic challenges from microorganisms, the former benefitting the plant and agriculture and the latter causing disease and economic harm. Plant innate immunity describes a highly conserved set of defense mechanisms that play pivotal roles in sensing immunogenic signals associated with both symbiotic and pathogenic microbes and subsequent downstream activation of signaling effector networks that protect the plant. An intriguing question is how the innate immune system distinguishes “friends” from “foes”. Here, we summarize recent advances in our understanding of the role and spectrum of innate immunity in recognizing and responding to different microbes. In addition, we also review some of the strategies used by microbes to manipulate plant signaling pathways and thus evade immunity, with emphasis on the use of effector proteins and micro-RNAs (miRNAs). Furthermore, we discuss potential questions that need addressing to advance the field of plant–microbe interactions.
