Three LysM effectors of Zymoseptoria tritici collectively disarm chitin-triggered plant immunity [PDF]

Molecular Plant Pathology, 2020
SUMMARY Chitin is a major structural component of fungal cell walls and acts as a microbe-associated molecular pattern (MAMP) that, upon recognition by a plant host, triggers the activation of immune responses. In order to avoid the activation of these responses, the Septoria tritici blotch (STB) pathogen of wheat,

The short chitooligosaccharide CO4 inhibits chitin-triggered immunity in grapevine and promotes the infection by Botrytis cinerea but not Plasmopara viticola. [PDF]

J Exp Bot
Abstract Plants have developed strategies to detect different microorganisms and specifically modulate their immune responses. A primary recognition involves the perception of highly conserved molecular signatures, also known as microbe-associated molecular patterns (MAMPs). Among them, chitin, the main component of the fungal cell wall,

Chitin Triggers Calcium-Mediated Immune Response in the Plant Model Physcomitrella patens [PDF]

Molecular Plant-Microbe Interactions®, 2020
A characteristic feature of a plant immune response is the increase of the cytosolic calcium (Ca2+) concentration following infection, which results in the downstream activation of immune response regulators. The bryophyte Physcomitrella patens has been shown to mount an immune response when exposed to bacteria, fungi, or chitin elicitation, in a ...

A Case of Plant Vaccination: Enhancement of Plant Immunity against Verticillium dahliae by Necrotized Spores of the Pathogen

Plants, 2022
The soil-borne fungus Verticillium dahliae is causing a devastating vascular disease in more than 200 species of dicotyledonous plants. The pathogen attacks susceptible plants through the roots, colonizes the plant vascular system, and causes the death ...

Maize Antifungal Protein AFP1 Elevates Fungal Chitin Levels by Targeting Chitin Deacetylases and Other Glycoproteins

mBio, 2023
Pathogenic fungi convert chitin to chitosan to evade plant perception and disarm chitin-triggered immune responses. Whether plants have evolved factors to counteract this evasion mechanism remains obscure.

Effector-Mediated Suppression of Chitin-Triggered Immunity by Magnaporthe oryzae Is Necessary for Rice Blast Disease   [PDF]

The Plant Cell, 2012
Abstract Plants use pattern recognition receptors to defend themselves from microbial pathogens. These receptors recognize pathogen-associated molecular patterns (PAMPs) and activate signaling pathways that lead to immunity. In rice (Oryza sativa), the chitin elicitor binding protein (CEBiP) recognizes chitin oligosaccharides released ...

NDR1/HIN1-Like Protein 13 Interacts with Symbiotic Receptor Kinases and Regulates Nodulation in Lotus japonicus

Molecular Plant-Microbe Interactions, 2022
Lysin-motif receptor-like kinases (LysM-RLKs) are involved in the recognition of microbe-associated molecular patterns to initiate pattern-triggered immunity (PTI). LysM-RLKs are also required for recognition of microbe-derived symbiotic signal molecules

Chitin receptorCERK1 links salt stress and chitin‐triggered innate immunity in Arabidopsis [PDF]

The Plant Journal, 2017
SummaryIn nature, plants need to respond to multiple environmental stresses that require the involvement and fine‐tuning of different stress signaling pathways. Cross‐tolerance, in which plants pre‐treated with chitin (a fungal microbe‐associated molecular pattern) have improved salt tolerance, was observed in Arabidopsis, but is not well understood ...

Arabidopsis CPK5 Phosphorylates the Chitin Receptor LYK5 to Regulate Plant Innate Immunity

Frontiers in Plant Science, 2020
Chitin, a major component of the fungal cell wall, triggers plant innate immunity in Arabidopsis via a receptor complex including two major lysin motif receptor-like kinases, AtLYK5, and AtCERK1.

Pattern-triggered immunity suppresses programmed cell death triggered by fumonisin b1. [PDF]

PLoS ONE, 2013
Programmed cell death (PCD) is a crucial process for plant innate immunity and development. In plant innate immunity, PCD is believed to prevent the spread of pathogens from the infection site.
