THE INNATE IMMUNITY RESPONSES IN RUBBER TREE
Plant innate immunity system consists of two branches: pathogen associated molecular patterns (PAMPs) -triggered immunity (PTI) and effector-triggered immunity (ETI).

Hide-and-Seek: Chitin-Triggered Plant Immunity and Fungal Counterstrategies
Trends in Plant Science, 2020Fungal pathogens are major destructive microorganisms for land plants and pose growing challenges to global crop production. Chitin is a vital building block for fungal cell walls and also a broadly effective elicitor of plant immunity. Here we review the rapid progress in understanding chitin perception and signaling in plants and highlight ...

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.

Functional Plant Biology, 2022
Plant diseases seriously damage crop production, and most plant diseases are caused by fungi. Fungal cell walls contain chitin, a highly conserved component that is widely recognised by plants as a PAMP (pathogen-associated molecular pattern) to induce defence responses.

The Bifunctional Plant Receptor, OsCERK1, Regulates Both Chitin-Triggered Immunity and Arbuscular Mycorrhizal Symbiosis in Rice [PDF]
Plants are constantly exposed to threats from pathogenic microbes and thus developed an innate immune system to protect themselves. On the other hand, many plants also have the ability to establish endosymbiosis with beneficial microbes such as arbuscular mycorrhizal (AM) fungi or rhizobial bacteria, which improves the growth of host plants. How plants

Botrytis cinerea and Sclerotinia sclerotiorum, two closely related necrotrophic fungal pathogens, secrete large amounts of oxalic acid (OA) into the plant apoplast to suppress host immunity, though the underlying mechanisms remain unclear. Here, we demonstrate that OA-induced virulence in Arabidopsis thaliana depends on CERK1, a coreceptor critical for

The grapevine LysM receptor-like kinase VvLYK5-1 mediates chitin-triggered immunity
2021The establishment of defense reactions to protect plants against invading pathogens first requiresthe recognition of Microbe-Associated Molecular Patterns (MAMPs), detected by plasmamembrane-bound Pattern Recognition Receptors (PRRs). These MAMPs, also termed elicitors, areused in several biocontrol products that are gradually developing to reduce the ...
