Features of the organization and functioning of a unique class of plant receptor kinases containing lysm-motives in the extracellular domain

Abstract

Analysis of current data concerning functioning, structural organization and evolutionary aspects of origin for a unique class of the plant LysM-receptors has been performed. Plant receptors with LysM-motifs in the extracellular domain act as mediators in recognition of N-acetylglucosamine-containing compounds. Such compounds from pathogenic bacteria and fungi cause activation of plant defense systems, while the compounds secreted by symbiotic microorganisms trigger endosymbiosis formation. A possible mode of receptor operation in binding of structurally similar microbial signals, that leads to pathogen resistance or endosymbiosis development, as well as the role of LysM-receptors in these processes, have been examined.
