Visualization of cellulose synthase demonstrates functional association with microtubules. The cellulose synthases are cargo of the TPLATE adaptor complex. Cellulose synthase complexes display distinct dynamic behaviors during xylem transdifferentiation. Hitting the wall-sensing and signaling pathways involved in plant cell wall remodeling in response to abiotic stress. Novaković, L., Guo, T., Bacic, A., Sampathkumar, A. Plant cell wall-mediated immunity: cell wall changes trigger disease resistance responses. Plant cell wall signaling and receptor-like kinases. Tailor-made trees: engineering lignin for ease of processing and tomorrow’s bioeconomy. Are designer plant cell walls a realistic aspiration or will the plasticity of the plant’s metabolism win out? Curr. 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.ĭoblin, M. 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. However, recently developed technologies in combination with more established genetic and biochemical approaches are beginning to open up this exciting field of study. 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.
