LYK3 — Pisum sativum

Summary

PsLYK3 (PSAT4G197320) on garden pea chromosome 4LG4 encodes a LysM domain receptor-like kinase 3, a transmembrane receptor with protein serine/threonine kinase activity and chitin binding. This gene is associated with nodulation, response to symbiotic bacteria, and regulation of leaf senescence. It is linked to calcium signaling, MAPK cascade, intracellular signal transduction, and hormone-mediated signaling including ABA and brassinosteroid pathways. PsLYK3 is associated with downregulation of defense response, regulation of ROS metabolic process, and innate immune response-activating signaling. Localization evidence places the product at the plasmalemma and vacuolar lumen. Studies of related genes in other species link the family to resistance against Botrytis cinerea and Pectobacterium carotovorum, as well as abscisic acid sensitivity and disease tolerance.
