%X <span style=\"font-size:14px;\">植物通过先天免疫反应抵抗病原体的攻击，先天免疫反应由细胞表面定位模式识别受体(PRRs)和细胞内核苷酸结合域富含亮氨酸重复序列受体(NLRs)启动，分别导致模式触发免疫(PTI)和效应子触发免疫(ETI)。尽管这两类免疫受体涉及不同的激活机制，似乎需要不同的早期信号成分，但PTI和ETI最终收敛为许多类似的下游反应，尽管幅度和动态不同。越来越多的证据表明，PRR介导的信号级联和NLR介导的信号级联之间存在复杂的相互作用，以及两者共享的共同信号成分。未来对PRR启动和NLR启动的免疫之间信号协同机制的研究将使我们更全面地了解植物免疫系统。本文综述了我们对植物先天免疫两层之间关系认识的最新进展。</span><br />
<span style=\"font-size:14px;\">Plants resist attacks by pathogens via innate immune responses, which are initiated by cell surface-localized pattern-recognition receptors (PRRs) and intracellular nucleotide-binding domain leucine-rich repeat containing receptors (NLRs) leading to pattern-triggered immunity (PTI) and effector-triggered immunity (ETI), respectively. Although the two classes of immune receptors involve different activation mechanisms and appear to require different early signaling components, PTI and ETI eventually converge into many similar downstream responses, albeit with distinct amplitudes and dynamics. Increasing evidence suggests the existence of intricate interactions between PRR-mediated and NLR-mediated signaling cascades as well as common signaling components shared by both. Future investigation of the mechanisms underlying signal collaboration between PRR-initiated and NLR-initiated immunity will enable a more complete understanding of the plant immune system. This review discusses recent advances in our understanding of the relationship between the two layers of plant innate immunity.</span>
