The plant cell wall is the first physical and defensive barrier against pathogens. The plant cell wall usually undergoes dynamic remodeling as an immune response to prevent infection by pathogens. In this review, we summarize advances on relationship between cell wall and immunity in plants. In particular, we outline current progresses regarding the regulation of the cell wall components, including cellulose, hemicellulose, pectin and lignin, on plant disease resistance. We also discuss the impacts of cell wall-derived cellodextrin, oligogalacturonic acid and xyloglucan/xylan oligosaccharides as potent elicitors or signal molecules to trigger plant immune response. We further propose future studies on dissecting the molecular regulation of cell wall on plant immunity, which have potentials in practical application of crop breeding aiming at improvement of plant disease resistance.
植物细胞壁是抵御病原体的第一道物理和防御屏障。植物细胞壁通常会经历动态重塑，作为一种免疫反应来防止病原体感染。在本综述中，我们总结了植物细胞壁与免疫之间关系的研究进展。特别是，我们概述了目前关于细胞壁成分（包括纤维素、半纤维素、果胶和木质素）对植物抗病性调控的研究进展。我们还讨论了细胞壁衍生的纤维二糖、低聚半乳糖醛酸和木葡聚糖/木聚糖寡糖作为强效激发子或信号分子对触发植物免疫反应的影响。我们进一步提出了未来关于剖析细胞壁对植物免疫分子调控的研究方向，这些研究在旨在提高植物抗病性的作物育种实际应用中具有潜力。
