LYK5 — Phaseolus vulgaris

Summary

PHAVU_008G212500 (PvLYK5) on chromosome 8 of French bean encodes a LysM domain-containing receptor-like kinase with protein serine/threonine kinase activity, chitin and chitosan binding, and transmembrane receptor protein kinase activity. It is associated with cellular response to chitin, detection of molecules of fungal and bacterial origin, cell surface PRR signaling, and upregulation of defense response to oomycetes. The gene is linked to bacterial blight disease resistance, disease tolerance, salt tolerance, stomatal closure, and resistance to Botrytis cinerea and Fusarium graminearum. It also connects to flower morphogenesis, leaf senescence regulation, and plant epidermal cell differentiation. Studies of related genes in other species link the family to chitin response, innate immunity, and bacterial and fungal disease resistance.
