Chitin modulates innate immune responses of keratinocytes. [PDF]
PLoS ONE, 2011 BACKGROUND: Chitin, after cellulose the second most abundant polysaccharide in nature, is an essential component of exoskeletons of crabs, shrimps and insects and protects these organisms from harsh conditions in their environment.

eLife, 2014 Chitin is a fungal microbe-associated molecular pattern recognized in Arabidopsis by a lysin motif receptor kinase (LYK), AtCERK1. Previous research suggested that AtCERK1 is the major chitin receptor and mediates chitin-induced signaling through ...

Chitin‐induced and CHITIN ELICITOR RECEPTOR KINASE1 (CERK1) phosphorylation‐dependent endocytosis of Arabidopsis thaliana LYSIN MOTIF‐CONTAINING RECEPTOR‐LIKE KINASE5 (LYK5) [PDF]
New Phytologist, 2017 Summary To detect potential pathogens, plants perceive the fungal polysaccharide chitin through receptor complexes containing lysin motif receptor‐like kinases (LysM‐RLKs). To investigate the ligand‐induced spatial dynamics of chitin receptor components, we studied the subcellular behaviour of two Arabidopsis thaliana LysM‐RLKs involved in chitin ...

Chitin-Induced Dimerization Activates a Plant Immune Receptor
Science, 2012 Dissecting Chitin Binding The chitin in fungal cells walls serves as a trigger to initiate plant defenses against pathogenic fungi. Arabidopsis detects these signals through a cell surface chitin receptor whose intracellular kinase domain initiates a signaling cascade in ...

mBio, 2016 Chitin is an important cell wall component of Aspergillus fumigatus conidia, of which hundreds are inhaled on a daily basis. Previous studies have shown that chitin has both anti- and proinflammatory properties; however the exact mechanisms determining ...

Fungal effector Ecp6 outcompetes host immune receptor for chitin binding through intrachain LysM dimerization [PDF]
eLife, 2013 While host immune receptors detect pathogen-associated molecular patterns to activate immunity, pathogens attempt to deregulate host immunity through secreted effectors.

Chitosan perception in Arabidopsis requires the chitin receptor AtCERK1 suggesting an improved model for receptor structure and function [PDF]
, 2017 Abstract Chitin, a linear polymer of N-acetyl-D-glucosamine, and chitosans, fully or partially deacetylated derivatives of chitin, are known to elicit defense reactions in higher plants. We compared the ability of chitin and chitosan oligomers and polymers (chitin oligomers with degree of polymerization 3 to 8 ...

A Receptor-like Cytoplasmic Kinase Targeted by a Plant Pathogen Effector Is Directly Phosphorylated by the Chitin Receptor and Mediates Rice Immunity [PDF]
Cell Host & Microbe, 2013 CERK1 is a lysine motif-containing plant pattern recognition receptor for chitin and peptidoglycan. Chitin recognition by OsCERK1 triggers rapid engagement of a rice MAP kinase cascade, which leads to defense response activation. How the MAP kinase cascades are engaged downstream of OsCERK1 remains obscure.

Chitin and chitin-related compounds in plant–fungal interactions [PDF]
Mycology, 2018 Chitin is the second abundant polysaccharide in the world after cellulose. It is a vital structural component of the fungal cell wall but not for plants.

Chitin receptor-mediated activation of MAP kinases and ROS production in rice and Arabidopsis. [PDF]
Plant Signal Behav, 2017 Rapid induction of plant immune responses is essential to inhibit colonization and invasion by pathogens. Plants can recognize pathogen-associated molecular patterns (PAMPs) including fungal chitin and bacterial flagellin using pattern-recognition receptors (PRRs), which trigger the intracellular activation of mitogen-activated protein kinase (MAPK ...
