Abstract:

Lysin motif (LysM) is a ubiquitous protein domain found in most living organisms. LysM-containing proteins in plant cells can recognize different GlcNAc-containing ligands, thereby triggering specific defense responses to pathogens. As a group of important pattern recognition receptors, LysM-containing proteins trigger downstream signaling by oligomerization, thus interacting with the Botrytis-induced kinase 1 (BIK1) and mitogen-activated protein kinase (MAPK) cascade. Pathogenic microorganisms also use certain mechanisms to escape from pathogen-associated molecular pattern-triggered immunity by utilizing specific recognition or modification of pattern recognition receptors by the secreted effector proteins. This review focuses on the functions of these receptor kinases/proteins in response to elicitor stimuli and priming of defense responses.
