Abstract

The plant cell wall, a dynamic network of polysaccharides and glycoproteins of significant compositional and structural complexity, functions in plant growth, development and stress responses. In recent years, the existence of plant cell wall integrity (CWI) maintenance mechanisms has been demonstrated, but little is known about the signaling pathways involved, or their components. Examination of key mutants has shed light on the relationships between cell wall remodeling and plant cell responses, indicating a central role for the regulatory network that monitors and controls cell wall performance and integrity. In this review, we present a short overview of cell wall composition and discuss post-synthetic cell wall modification as a valuable approach for studying CWI perception and signaling pathways.

摘要

植物细胞壁是一个由多糖和糖蛋白组成的动态网络,具有显著的组成和结构复杂性,在植物生长、发育和应激反应中发挥作用。近年来,已经证明了植物细胞壁完整性(CWI)维持机制的存在,但对于涉及的信号通路或其组成部分知之甚少。对关键突变体的研究揭示了细胞壁重塑与植物细胞反应之间的关系,表明监测和控制细胞壁性能和完整性的调控网络起着核心作用。在这篇综述中,我们简要介绍了细胞壁的组成,并讨论了细胞后合成修饰作为研究 CWI 感知和信号通路的一种有价值的方法。
