Chitin-induced systemic disease resistance in rice requires both OsCERK1 and OsCEBiP and is mediated via perturbation of cell-wall biogenesis in leaves [PDF]
Frontiers in Plant Science, 2022 Chitin is a well-known elicitor of disease resistance and its recognition by plants is crucial to perceive fungal infections. Chitin can induce both a local immune response and a systemic disease resistance when provided as a supplement in soils.

Chitin-Induced Airway Epithelial Cell Innate Immune Responses Are Inhibited by Carvacrol/Thymol. [PDF]
PLoS ONE, 2016 Chitin is produced in large amounts by fungi, insects, and other organisms and has been implicated in the pathogenesis of asthma. Airway epithelial cells are in direct contact with environmental particles and serve as the first line of defense against ...

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 ...

Fungal dual-domain LysM effectors undergo chitin-induced intermolecular, and not intramolecular, dimerization. [PDF]
Plant Physiol, 2022 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 ...

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

The Arabidopsis small G-protein AtRAN1 is a positive regulator in chitin-induced stomatal closure and disease resistance. [PDF]
Mol Plant Pathol, 2021 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.

Comparison of chitin-induced natural transformation in pandemic Vibrio cholerae O1 El Tor strains. [PDF]
Environ Microbiol, 2020 Summary The human pathogen Vibrio cholerae serves as a model organism for many important processes ranging from pathogenesis to natural transformation, which has been extensively studied in this bacterium.

Microfluidic Interrogation of Chitin-Induced Calcium Oscillations in the Moss Physcomitrium patens [PDF]
Plants (Basel)Plants 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.

Conversion of a recA-Mediated Non-toxigenic Vibrio cholerae O1 Strain to a Toxigenic Strain Using Chitin-Induced Transformation [PDF]
Frontiers in Microbiology, 2019 Toxigenic Vibrio cholerae strains, including strains in serogroups O1 and O139 associated with the clinical disease cholera, are ubiquitous in aquatic reservoirs, including fresh, estuarine, and marine environments.

Two transmembrane transcriptional regulators coordinate to activate chitin-induced natural transformation in Vibrio cholerae. [PDF]
PLoS GenetABSTRACT Transcriptional regulators are a broad class of proteins that alter gene expression in response to environmental stimuli. Transmembrane transcriptional regulators (TTRs) are a subset of transcriptional regulators in bacteria that can directly regulate gene expression while remaining anchored in the membrane ...
