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

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, is well known to be particularly active in triggering immunity in many plant species, including grapevine. While chitin is a well-known elicitor of plant defenses, other MAMPs such as short chitooligosaccharides [e.g. chitotetraose (CO4)] and lipo-chitooligosaccharides (LCOs) have been described to promote symbiotic interactions and inhibit plant immunity in several plant species. Here, we analyzed the molecular signaling triggered by these MAMPs in grapevine, focu
