A lysin motif effector subverts chitin‐triggered immunity to facilitate arbuscular mycorrhizal symbiosis [PDF]
New Phytologist, 2020 Summary Arbuscular mycorrhizal (AM) fungi greatly improve mineral uptake by host plants in nutrient‐depleted soil and can intracellularly colonize root cortex cells in the vast majority of higher plants. However, AM fungi possess common fungal cell wall components such as chitin that can be recognized by plant chitin receptors to trigger immune ...

A chitin deacetylase Ps CDA2 from Puccinia striiformis f. sp. tritici confers disease pathogenicity by suppressing chitin‐triggered immunity in wheat [PDF]
Molecular Plant Pathology, 2023 Plants have the ability to recognize the essential chitin molecule present in the fungal cell wall, which stimulates the immune response. Phytopathogenic fungi have developed various strategies to inhibit the chitin-triggered immune response. Here, we identified a chitin deacetylase of Puccinia striiformis f. sp.

Chitin-Binding Protein of Verticillium nonalfalfae Disguises Fungus from Plant Chitinases and Suppresses Chitin-Triggered Host Immunity [PDF]
Molecular Plant-Microbe Interactions, 2019 During fungal infections, plant cells secrete chitinases, which digest chitin in the fungal cell walls. The recognition of released chitin oligomers via lysin motif (LysM)-containing immune host receptors results in the activation of defense signaling ...

Multiple Chitin- or Avirulent Strain-Triggered Immunity Induces Microbiome Reassembly in Rice
MicroorganismsMagnaporthe oryzae is one of the most important fungal pathogens of rice. Chitin and avirulent strains can induce two layers of immunity response, pathogen-associated molecular pattern (PAMP)-triggered immunity (PTI) and effector-triggered immunity (ETI),

Domain gain or loss in a fungal chitinase enables specialization towards antagonism or immune suppression [PDF]
Nature CommunicationsEffector proteins orchestrate interactions that determine host compatibility and microbial competition. Among these are microbial chitinases, widespread enzymes involved in nutrient acquisition, fungal cell-wall remodelling, and antagonism, yet how their

OsCERK2/OsRLK10, a homolog of OsCERK1, has a potential role for chitin-triggered immunity and arbuscular mycorrhizal symbiosis in rice. [PDF]
Plant Biotechnol (Tokyo), 2022 In rice, the lysin motif (LysM) receptor-like kinase OsCERK1, originally identified as the essential molecule for chitin-triggered immunity, plays a key role in arbuscular mycorrhizal (AM) symbiosis. As we previously reported, although AM colonization was largely repressed at 2 weeks after inoculation (WAI), arbuscules were observed at 5 WAI in oscerk1

A haustorial-expressed lytic polysaccharide monooxygenase from the cucurbit powdery mildew pathogen Podosphaera xanthii contributes to the suppression of chitin-triggered immunity. [PDF]
Mol Plant Pathol, 2021 AbstractPodosphaera xanthii is the main causal agent of cucurbit powdery mildew and a limiting factor of crop productivity. The lifestyle of this fungus is determined by the development of specialized parasitic structures inside epidermal cells, termed haustoria, that are responsible for the acquisition of nutrients and the release of effectors.

Chitin Triggers Tissue-Specific Immunity in Wheat Associated With Fusarium Head Blight [PDF]
Frontiers in Plant Science, 2022 Fusarium graminearum is one of the primary causal agents of Fusarium head blight (FHB) on wheat and barley. FHB reduces grain yield and contaminates grain with various mycotoxins, including deoxynivalenol (DON). DON acts as a virulence factor to promote the fungus passing the rachis node and spreading throughout the head of wheat but not barley ...

Plasmodiophora brassicae CBM18 Proteins Bind Chitin and Suppress Chitin-Triggered Immunity [PDF]
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. For instance, the clubroot pathogen Plasmodiophora brassicae is able to turn the roots of susceptible hosts into nutrient-sink galls suppressing pattern-triggered immunity (PTI) and ...
