Plant genomes possess hundreds of candidate surface localized receptors capable of recognizing microbial components or modified-self molecules. Surface-localized pattern recognition receptors (PRRs) can recognize proteins, peptides, or structural microbial components as nonself, triggering complex signaling pathways leading to defense. PRRs possess diverse extracellular domains capable of recognizing epitopes, lipids, glycans and polysaccharides. Recent work highlights advances in our understanding of the diversity and evolution of PRRs recognizing pathogen components. We also discuss PRR functional diversification, pathogen strategies to evade detection, and the role of tissue and age-related resistance for effective plant defense.
植物基因组拥有数百种候选的表面定位受体，能够识别微生物成分或修饰自身的分子。表面定位的模式识别受体 (PRR) 可以识别蛋白质、肽或结构微生物成分作为非自身，触发复杂的信号通路导致防御。PRR 具有多种能够识别表位、脂质、聚糖和多糖的细胞外结构域。最近的研究强调了我们对识别病原体成分的 PRR 多样性和进化的理解的进展。我们还讨论了 PRR 功能多样化、病原体逃避检测的策略以及组织和年龄相关抗性在有效植物防御中的作用。
