LYK3 — Medicago truncatula

Summary

MTR_5G086540 (LYK3) on barrel medic chromosome 5 encodes a transmembrane receptor protein serine/threonine kinase with chitin-binding and sugar-binding activity, belonging to the LysM_RLK3/10 and CERK1/LYK3-like families. The gene is associated with nitrogen fixation, response to symbiotic bacteria, and response to chitin, as well as defense response to oomycetes, innate immune response-activating signaling, and regulation of reactive oxygen species. It has been linked to endocytosis, vesicle localization, cell death, hypersensitive response-programmed cell death, inhibition of salinity response, regulation of leaf senescence, megasporogenesis, microsporogenesis, anther wall tapetum development, chloroplast organization, and virus-induced post-transcriptional gene silencing. The product localizes to the membrane, plasmalemma, and vacuolar lumen. Studies of related genes in other species, including RLK10, RLK9, and PSKR, connect the family to additional signaling roles.
