A communication system between plant cells and their surrounding cell wall is required to coordinate development, immunity, and the integration of environmental cues. This communication network is facilitated by a large pool of membrane- and cell-wall-anchored proteins that can potentially interact with the matrix or its fragments, promoting cell wall patterning or eliciting cellular responses that may lead to changes in the architecture and chemistry of the wall. A mechanistic understanding of how these receptors and cell wall proteins recognize and interact with cell wall epitopes would be key to a better understanding of all plant processes that require cell wall remodeling such as expansion, morphogenesis, and defense responses. This review focuses on the latest developments in structurally and biochemically characterized receptors and protein complexes implicated in reading and regulating cell wall integrity and immunity.

植物细胞与其周围细胞壁之间的通信系统需要协调发育、免疫和环境线索的整合。这种通讯网络由大量膜和细胞壁锚定蛋白促进，这些蛋白可能与基质或其片段相互作用，促进细胞壁图案化或引发细胞反应，从而可能导致细胞结构和化学的变化。墙。从机制上理解这些受体和细胞壁蛋白如何识别细胞壁表位并与之相互作用，对于更好地理解所有需要细胞壁重塑的植物过程（例如扩张、形态发生和防御反应）至关重要。本综述重点关注与读取和调节细胞壁完整性和免疫相关的结构和生化特征受体和蛋白质复合物的最新进展。
