Fungal dual-domain LysM effectors undergo chitin-induced intermolecular, and not intramolecular, dimerization [PDF]
Plant Physiology, 2020 Abstract Chitin is a homopolymer of β-(1,4)-linked N-acetyl-D-glucosamine (GlcNAc) and a major structural component of fungal cell walls. In plants, chitin acts as a microbe-associated molecular pattern (MAMP) that is recognized by lysin motif (LysM)-containing plant cell surface-localized pattern recognition receptors (PRRs) that ...

Chitin induces steroid-resistant airway inflammation and airway hyperresponsiveness in mice
Allergology International, 2021 Background: Previous reports have shown that pathogen-associated patterns (PAMPs) induce the production of interleukin (IL)-1β in macrophages. Moreover, studies using mouse models also suggest that chitin, which acts as a PAMP, induces adjuvant effects ...

Characterization of Early, Chitin-Induced Gene Expression in Arabidopsis [PDF]
Molecular Plant-Microbe Interactions, 2002 Three genes (i.e., a zinc finger protein, a lectin-like protein, and AtMPK3), previously shown to respond to chitin elicitation in microarray experiments, were used to examine the response of Arabidopsis spp. to chitin addition. Maximum induction for all

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.

Chitin-Induced Carbotype Conversion in Vibrio vulnificus [PDF]
Infection and Immunity, 2011 ABSTRACT As an etiological agent of bacterial sepsis and wound infections, Vibrio vulnificus is unique among the Vibrionaceae . The most intensely studied of its virulence factors is the capsular polysaccharide (CPS).

The Arabidopsis small G‐protein AtRAN1 is a positive regulator in chitin‐induced stomatal closure and disease resistance [PDF]
Molecular Plant Pathology, 2020 AbstractChitin, a fungal microbial‐associated molecular pattern, triggers various defence responses in several plant systems. Although it induces stomatal closure, the molecular mechanisms of its interactions with guard cell signalling pathways are unclear.

Chitin nanofiber elucidates the elicitor activity of polymeric chitin in plants [PDF]
Frontiers in Plant Science, 2015 Chitin, an N-acetyl-D-glucosamine polymer, is a component of fungal cell walls and a microbe/pathogen-associated molecular pattern that elicits plant defense responses.

Microfluidic Interrogation of Chitin-Induced Calcium Oscillations in the Moss Physcomitrium patens [PDF]
PlantsPlants defend against pathogens such as fungi by initiating coordinated structural and chemical responses. Pathogen perception triggers rapid cytosolic calcium influx and calcium oscillations that drive defense gene expression, yet the mechanisms by which these signals encode stressor intensity and propagate systematically remain unclear.

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 ...
