LYK3 — Cicer arietinum

Summary

CaLYK3 (LOC101489148) on chickpea chromosome 7 encodes a transmembrane receptor serine/threonine kinase with a LysM domain, belonging to the CERK1/LYK3-like family, and exhibits chitin-binding and signaling receptor activity. In chickpea, CaLYK3 is associated with nitrogen fixation, nodulation, response to symbiotic bacteria, and downregulation of defense responses, as well as regulation of leaf senescence, abscisic acid signaling, reactive oxygen species metabolism, and innate immune signaling. It is also linked to brassinosteroid detection, chloroplast organization, and post-embryonic development, and localizes to the plasma membrane and vacuolar lumen. Related genes in other species are associated with resistance to Botrytis cinerea and Pectobacterium carotovorum, as well as abscisic acid sensitivity.
