The <i>Vitis vinifera</i> receptor VvLYK6 negatively regulates chitin-triggered immune responses and promotes fungal infections.

ABSTRACT:

Introduction

Botrytis cinerea is recognized as one of the most damaging fungal pathogens affecting grapevine (Vitis vinifera), directly impacting both grape yield and wine quality. Identifying new genes involved in the interaction between V. vinifera and B. cinerea appears to be a promising strategy for enhancing grapevine resistance in future breeding programs. During pathogen infection, plasma membranelocalized pattern recognition receptors (PRRs) are responsible for detecting conserved microbe-associated molecular patterns (MAMPs). Among PRRs, members of the LysM receptor-like kinase family are well known to mediate the recognition of fungal MAMPs and trigger plant immune signaling pathways. Interestingly, a novel member of this receptor family, named VvLYK6
