Resumen
[EN] Plants have evolved a repertoire of monitoring systems to sense plant morphogenesis and to face environmental
changes and threats caused by different attackers. These systems integrate different signals into
overreaching triggering pathways which coordinate developmental and defence-associated responses. The
plant cell wall, a dynamic and complex structure surrounding every plant cell, has emerged recently as an
essential 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 diverse
set of plasma membrane-resident sensors and pattern recognition receptors (PRRs). The PRRs perceive
plant-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), which
shares signalling components and responses with the immune pathways triggered by non-self microbeassociated
molecular patterns that mediate disease resistance. Alteration of CWI by impairment of the
expression or activity of proteins involved in cell wall biosynthesis and/or remodelling, as occurs in some
plant cell wall mutants, or by wall damage due to colonization by pathogens/pests, activates specific defensive
and growth responses. Our current understanding of how these alterations of CWI are perceived by the
wall monitoring systems is scarce and few plant sensors/PRRs and DAMPs have been characterized. The
identification of these CWI sensors and PRR–DAMP pairs will help us to understand the immune functions
of the wall monitoring system, and might allow the breeding of crop varieties and the design of agricultural
strategies that would enhance crop disease resistance.
