细胞壁是高度动态的结构，在生长、发育和适应变化的环境期间为植物细胞提供机械支持。因此，对植物来说，监测其细胞壁的状态并确保其功能的完整性是非常重要的。这种监测涉及感知细胞壁-质膜界面处的物理力。这些力量在细胞分裂和形态发生过程中以及对各种非生物和生物胁迫的反应中发生变化。负责感知这些过程中涉及的物理刺激的机制一直难以与感知化学信号（如激素、肽或细胞壁片段）的其他调节机制分开。然而，最近开发的技术与更成熟的遗传和生物化学方法相结合，开始开辟这一令人兴奋的研究领域。在这里，我们将回顾我们目前的知识，植物细胞壁完整性信号，使用选定的最新研究结果，并强调如何细胞壁-质膜界面可以作为一个场所，用于感知影响植物发育和应激反应的物理力量的变化。更重要的是，我们讨论了如何将这些信号与来自已建立的信号级联的化学信号相结合，以控制特定的适应性反应，在暴露于生物和非生物胁迫。
Cell walls are highly dynamic structures that provide mechanical support for plant cells during growth, development and adaptation to a changing environment. Thus, it is important for plants to monitor the state of their cell walls and ensure their functional integrity at all times. This monitoring involves perception of physical forces at the cell wall–plasma membrane interphase. These forces are altered during cell division and morphogenesis, as well as in response to various abiotic and biotic stresses. Mechanisms responsible for the perception of physical stimuli involved in these processes have been difficult to separate from other regulatory mechanisms perceiving chemical signals such as hormones, peptides or cell wall fragments. However, recently developed technologies in combination with more established genetic and biochemical approaches are beginning to open up this exciting field of study. Here, we will review our current knowledge of plant cell wall integrity signalling using selected recent findings and highlight how the cell wall–plasma membrane interphase can act as a venue for sensing changes in the physical forces affecting plant development and stress responses. More importantly, we discuss how these signals may be integrated with chemical signals derived from established signalling cascades to control specific adaptive responses during exposure to biotic and abiotic stresses.
