Fungal pathogens are major destructive microorganisms for land plants and pose growing challenges to global crop production. Chitin is a vital building block for fungal cell walls and also a broadly effective elicitor of plant immunity. Here we review the rapid progress in understanding chitin perception and signaling in plants and highlight similarities and differences of these processes between arabidopsis and rice. We also outline moonlight functions of CERK1, an indispensable chitin coreceptor conserved across the plant kingdom, which imply potential crosstalk between chitin signaling and symbiotic or biotic/abiotic stress signaling in plants via CERK1. Moreover, we summarize current knowledge about fungal counterstrategies for subverting chitin-triggered plant immunity and propose open questions and future directions in this field.

捉迷藏:几丁质引发的植物免疫力和真菌对策。

真菌病原体是陆地植物的主要破坏性微生物,对全球农作物的生产构成越来越大的挑战。几丁质是真菌细胞壁的重要组成部分,也是植物免疫力的广泛有效引发剂。在这里,我们回顾了在理解植物中几丁质感知和信号传导方面的快速进展,并突出了拟南芥和水稻之间这些过程的异同。我们还概述了CERK1的月光功能,CERK1是在整个植物界保存的必不可少的几丁质共受体,这暗示着几丁质信号与通过CERK1在植物中的共生或生物/非生物胁迫信号之间的潜在串扰。此外,我们总结了有关真菌对策的最新知识,以破坏几丁质触发的植物免疫力,并提出了该领域的未解决问题和未来方向。
