Plant plasma membrane pattern recognition receptors are key to microbe sensing and activation of immunity to microbial invasion. Plants employ several types of such receptors that differ mainly in the structure of their ectodomains and the presence or absence of a cytoplasmic protein kinase domain. Plant immune receptors do not function as single entities, but form larger complexes which undergo compositional changes in a ligand-dependent manner. Here, we highlight current knowledge of molecular mechanisms underlying receptor complex dynamics and regulation, and cover early signaling networks implicated in the activation of generic plant immune responses. We further discuss how an increasingly comprehensive set of immune receptors may be employed to engineer crop plants with enhanced, durable resistance to microbial infection.

植物质膜模式识别受体是感知微生物和激活自身免疫，抵抗微生物入侵的关键。植物具有一些这样的受体，不同受体主要在胞外域的机构以及是否存在胞质蛋白激酶结构域上存在差异。植物免疫受体并不单独发挥作用，它们会形成一个复杂的复合体，会经历配体依赖性的成分变化。本文，作者综述了目前我们对于受体复合物动态及调控分子机制的了解，包含与植物免疫响应激活密切相关的早期信号转导网络。作者进一步讨论了如何综合利用这些免疫受体来改良作物育种，增强作物对于微生物感染的抵抗力。
