The plant cuticle and cell wall separate microbial pathogens from the products of plant metabolism. While microbial pathogens try to breach these barriers for colonization, plants respond to attempted penetration by a battery of wall-associated defense reactions. Successful pathogens circumvent or suppress plant nonself recognition and basal defense during penetration and during microbial reproduction. Additionally, accommodation of fungal infection structures within intact cells requires host reprogramming. Recent data highlight that both early plant defense to fungal penetration and host reprogramming for susceptibility can function at the host cell periphery. Genetic evidence has also widened our understanding of how fungal pathogens are restricted during penetration at the plant cell wall. This review summarizes the current view of how plants monitor and model their cell periphery during interaction with microbial invaders.

细胞壁相关的抗病性和易感性机制。

植物角质层和细胞壁将微生物病原体与植物代谢产物分开。当微生物病原体试图突破这些定居障碍时，植物会通过一系列与壁相关的防御反应来对尝试的渗透做出反应。成功的病原体在渗透过程中和微生物繁殖过程中会规避或抑制植物的非自我识别和基础防御。另外，完整细胞内真菌感染结构的适应需要宿主重编程。最近的数据强调，早期植物对真菌渗透的防御和宿主对易感性的重新编程都可以在宿主细胞外围起作用。遗传证据还拓宽了我们对在植物细胞壁渗透过程中如何限制真菌病原体的理解。
