LYK3 — Cicer arietinum

Summary

CaLYK3 (LOC101496137) on chickpea chromosome 1 encodes a transmembrane receptor protein kinase with chitin-binding and protein tyrosine/serine/threonine kinase activities, belonging to the CERK1/LYK3-like LysM domain family. The gene is associated with nitrogen fixation, response to symbiotic bacteria, and regulation of defense responses to fungi and oomycetes. It is linked to immune response signaling, detection of brassinosteroid stimulus, abscisic acid-mediated signaling, reactive oxygen species metabolism, leaf senescence, chloroplast organization, and post-embryonic development. The product localizes to the plasma membrane and vacuolar lumen. Studies of related genes in other species connect the family to resistance against Botrytis cinerea and Pectobacterium carotovorum, as well as abscisic acid response and disease tolerance.
