LYK3 — Medicago truncatula

Summary

MTR_5G086030, also known as LYK3, encodes a transmembrane receptor protein serine/threonine kinase with chitin-binding activity, belonging to the LysM_RLK3/10 and CERK1/LYK3-like families. In barrel medic, this gene is associated with nitrogen fixation, response to symbiotic bacteria, response to chitin, and regulation of reactive oxygen species metabolic processes. It has also been linked to endocytosis, vesicle localization, flower morphogenesis, regulation of leaf senescence, sepal giant cell differentiation, anther wall tapetum development, microsporogenesis, megasporogenesis, and plant organ development. Additionally, LYK3 is associated with innate immune response-activating signaling, virus-induced PTGS, and chloroplast organization. The encoded protein localizes to the plasma membrane, membrane, MVB membrane, and vacuolar lumen. Studies of related genes in other species link the family to non-specific serine/threonine protein kinase activity (EC 2.7.11.1).
