所有植物病原体和寄生虫都必须制定策略来突破细胞壁，以便进入宿主的细胞质。细胞壁作为一种机械强度高、多层复合的外骨骼，不仅使植物能够长高，还能保护它们免受此类攻击。许多植物病原体使用一系列细胞壁降解酶，长期以来人们一直认为，对细胞壁完整性受损的检测有助于诱导防御反应。细胞壁碎片是与危险相关的分子模式（DAMPs），能够触发与微生物信号相当的防御信号通路，但情况可能更为复杂。细胞壁生物合成中的多种缺陷会导致病原体抗性增强。我们开始了解细胞壁完整性监测对植物生长的重要作用，并且细胞扩张、质膜 - 细胞壁接触以及次生壁生物合成等过程与植物免疫之间的联系正在显现。
All plant pathogens and parasites have had to develop strategies to overcome cell walls in order to access the host’s cytoplasm. As a mechanically strong, multi-layered composite exoskeleton, the cell wall not only enables plants to grow tall but also protects them from such attacks. Many plant pathogens employ an arsenal of cell wall degrading enzymes, and it has long been thought that the detection of breaches in wall integrity contributes to the induction of defense. Cell wall fragments are danger-associated molecular patterns or DAMPs that can trigger defense signaling pathways comparable to microbial signals, but the picture is likely to be more complicated. A wide range of defects in cell wall biosynthesis leads to enhanced pathogen resistance. We are beginning to understand the essential role of cell wall integrity surveillance for plant growth, and the connection of processes like cell expansion, plasma membrane–cell wall contact and secondary wall biosynthesis with plant immunity is emerging.
