Plant cells are encased in a polysaccharide-rich cell wall that provides protection against both biotic (pathogen attack) and abiotic (mechanical or osmotic) stressors. Emerging evidence indicates that cell wall damage (CWD) caused by such stressors is perceived by a class of receptor-like kinases (RLKs) that function as cell wall integrity (CWI) sensors, capable of recognizing and binding to fragmented polysaccharides. Using RNA-seq and phosphoproteomic approaches, we identified two receptor-like kinases that play distinct roles during CWD in the model moss Physcomitrium patens. Our work sheds light on the possible mechanisms by which early land plants surveil cell wall integrity and highlights the evolutionary divergence of cell wall signalling pathways.
