Plant cell wall integrity maintenance as an essential component of biotic stress response mechanisms
1Division of Cell and Molecular Biology, Department of Life Sciences, Imperial College London, London, UK.
Abstract:
Plant cell walls provide structural support during development and represent together with the cuticle the first line of defense against biotic and abiotic stress. In recent years, evidence has accumulated that a dedicated plant cell wall integrity (CWI) maintenance mechanism exists. This mechanism monitors and maintains functional integrity of the cell wall during different biological processes. The available data suggest that it may represent a component of the stress response mechanisms underlying biotic and abiotic stress responses, which has not been identified previously as a distinct mechanism. Here I will review the available evidence regarding the mode of action of the CWI maintenance mechanism and discuss its role in the context of biotic plant stress response mechanisms.
