The Lysin Motif Receptor-like Kinase (LysM-RLK) CERK1 Is a Major Chitin-binding Protein in Arabidopsis thaliana and Subject to Chitin-induced Phosphorylation [PDF]

open access: yesJournal of Biological Chemistry, 2010
Plants detect potential pathogens by sensing microbe-associated molecular patterns via pattern recognition receptors. In the dicot model plant Arabidopsis, the lysin motif (LysM)-containing chitin elicitor receptor kinase 1 (CERK1) has been shown to be essential for perception of the fungal cell wall component chitin and for resistance to fungal ...

Expression of the chimeric receptor between the chitin elicitor receptor CEBiP and the receptor-like protein kinase Pi-d2 leads to enhanced responses to the chitin elicitor and disease resistance against Magnaporthe oryzae in rice

Plant Molecular Biology, 2012
We previously reported that rice plants expressing the chimeric receptor consisting of rice chitin oligosaccharides binding protein (CEBiP) and the intracellular protein kinase region of Xa21, which confers resistance to rice bacterial blight, showed enhanced cellular responses to a chitin elicitor N-acetylchitoheptaose and increased resistance to the ...

AtLYK4 is the major chitin receptor in Arabidopsis with N-glycosylation and ligand-interacting residues orchestrating chitin perception

Science China Life Sciences
Fungi, arthropods, and nematodes are chitin-containing organisms that cause severe damage to crop production. Plants can sense chitin to activate immunity against these invaders. In Arabidopsis thaliana (Arabidopsis), the lysin motif-containing receptor kinases (LysM-RKs) AtLYK5 and AtCERK1 are considered the primary chitin receptor and coreceptor for ...

The sulfonylurea receptor Sur is dispensable for chitin synthesis in Drosophila melanogaster embryos

Pest Management Science, 2013
AbstractBACKGROUNDChitin produced by membrane‐inserted chitin synthases is an important constituent of the arthropod cuticle and midgut peritrophic matrix. Chitin synthesis inhibitors are common insecticides in pest control. As the target of sulfonylurea‐derived insecticides such as diflubenzuron, the ABC transporter sulfonylurea receptor (Sur) has ...

Saccharomyces cerevisiae cell wall chitin, the Kluyveromyces lactis zymocin receptor

Yeast, 2001
AbstractThe exozymocin secreted by Kluyveromyces lactis causes sensitive yeast cells, including Saccharomyces cerevisiae, to arrest growth in the G1 phase of the cell cycle. Despite its heterotrimeric (αβγ) structure, intracellular expression of its smallest subunit, the γ‐toxin, is alone responsible for the G1 arrest.

Activation of an antifungal pathway in Yersinia pseudotuberculosis by chitin-receptor-mediated fungal recognition

Current Biology
Despite the ubiquitous nature of bacterial-fungal interactions (BFIs), it is not fully understood how bacteria detect the presence of a potential fungal competitor to initiate appropriate defense responses. In this study, we show that the enteropathogen Yersinia pseudotuberculosis (Yptb) utilizes the two-component system (TCS) histidine kinase RstB to ...

Overexpression of plant chitin receptors in wheat confers broad‐spectrum resistance to fungal diseases

The Plant Journal
SUMMARYWheat (Triticum aestivum L.) is a globally staple crop vulnerable to various fungal diseases, significantly impacting its yield. Plant cell surface receptors play a crucial role in recognizing pathogen‐associated molecular patterns (PAMPs) and activating PAMP‐triggered immunity, boosting resistance against a wide range of plant diseases ...

Cell death signaling in the Arabidopsis chitin receptor mutant cerk1-4

Plant surface immunity is mediated by pattern recognition receptors (PRRs) that recognize con-served molecules derived from microorganisms. In Arabidopsis, CERK1 is the main component of the receptor complex that binds chitin and transduces the signal intracellularly (Miya et al., 2007; Petutschnig et al., 2010; Wan et al., 2008).
