AB [EN] Plants have evolved a repertoire of monitoring systems to sense plant morphogenesis and to face environmentalchanges and threats caused by different attackers. These systems integrate different signals intooverreaching triggering pathways which coordinate developmental and defence-associated responses. Theplant cell wall, a dynamic and complex structure surrounding every plant cell, has emerged recently as anessential component of plant monitoring systems, thus expanding its function as a passive defensive barrier.Plants have a dedicated mechanism for maintaining cell wall integrity (CWI) which comprises a diverseset of plasma membrane-resident sensors and pattern recognition receptors (PRRs). The PRRs perceiveplant-derived ligands, such as peptides or wall glycans, known as damage-associated molecular patterns(DAMPs). These DAMPs function as ‘danger’ alert signals activating DAMP-triggered immunity (DTI), whichshares signalling components and responses with the immune pathways triggered by non-self microbeassociatedmolecular patterns that mediate disease resistance. Alteration of CWI by impairment of theexpression or activity of proteins involved in cell wall biosynthesis and/or remodelling, as occurs in someplant cell wall mutants, or by wall damage due to colonization by pathogens/pests, activates specific defensiveand growth responses. Our current understanding of how these alterations of CWI are perceived by thewall monitoring systems is scarce and few plant sensors/PRRs and DAMPs have been characterized. Theidentification of these CWI sensors and PRR–DAMP pairs will help us to understand the immune functionsof the wall monitoring system, and might allow the breeding of crop varieties and the design of agriculturalstrategies that would enhance crop disease resistance.
