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. These forces are altered during cell division and morphogenesis, as well as in response to various abiotic and biotic stresses.
This monitoring involves perception of physical forces at the cell wall–plasma membrane interphase.
Thus, it is important for plants to monitor the state of their cell walls and ensure their functional integrity at all times. Cell walls are highly dynamic structures that provide mechanical support for plant cells during growth, development and adaptation to a changing environment.
