Suppression of Chitin-Triggered Immunity by a New Fungal Chitin-Binding Effector Resulting from Alternative Splicing of a Chitin Deacetylase Gene [PDF]
Journal of Fungi, 2022 Phytopathogenic fungi have evolved mechanisms to manipulate plant defences, such as chitin-triggered immunity, a plant defensive response based on the recognition of chitin oligomers by plant-specific receptors.

Suppression of Chitin-Triggered Immunity by Plant Fungal Pathogens: A Case Study of the Cucurbit Powdery Mildew Fungus Podosphaera xanthii [PDF]
Journal of Fungi, 2023 Fungal pathogens are significant plant-destroying microorganisms that present an increasing threat to the world’s crop production. Chitin is a crucial component of fungal cell walls and a conserved MAMP (microbe-associated molecular pattern) that can be ...

Plasmodiophora brassicae CBM18 Proteins Bind Chitin and Suppress Chitin-Triggered Immunity
PhytoFrontiers, 2022 Plants have a sophisticated and multilayered immune system. However, plant pathogens, helped by effector proteins, have found several strategies to evade plant immunity.

CERK1 is required for chitin-triggered reactive oxygen species generation in melon and is broadly conserved in cucurbits [PDF]
Plant Signaling & BehaviorCHITIN ELICITOR RECEPTOR KINASE 1 (CERK1), originally identified in Arabidopsis thaliana, encodes a pattern recognition receptor that perceives the fungal cell wall component called chitin to activate immune responses, including the production of ...

CRISPR/Cas9-based knockout of BnaLYK compromises pattern-triggered immunity and resistance to Sclerotinia sclerotiorum in Brassica napus [PDF]
BMC Plant BiologyRapeseed (Brassica napus) is severely threatened by Sclerotinia sclerotiorum, the causal agent of Sclerotinia stem rot (SSR). The lack of fully resistant cultivars, combined with the genetic complexity of rapeseed as an allopolyploid species, has ...

Chitin Deacetylase, a Novel Target for the Design of Agricultural Fungicides
Journal of Fungi, 2021 Fungicide resistance is a serious problem for agriculture. This is particularly apparent in the case of powdery mildew fungi. Therefore, there is an urgent need to develop new agrochemicals.

Acetylation and accessibility of Cryptococcus neoformans cell wall chitosans influence the strength of host immune responses [PDF]
The Cell SurfaceThe fungal pathogen Cryptococcus neoformans causes fatal cryptococcal meningitis, a significant global health risk. Unlike most fungi, C. neoformans expresses chitin deacetylases that convert its cell wall chitin into chitosan, helping to evade chitin ...
