LYK3 — Medicago truncatula

Summary

MTR_5G086040, symbol LYK3, encodes a LysM receptor-like kinase belonging to the CERK1/LYK3 family, with transmembrane receptor protein serine/threonine kinase activity, protein tyrosine kinase activity, chitin binding, and signaling receptor activity. In barrel medic, LYK3 is associated with nitrogen fixation, response to symbiotic bacteria, response to chitin, upregulation of defense response to oomycetes, and upregulation of innate immune response. It has also been linked to endocytosis, vesicle localization, regulation of leaf senescence, flower morphogenesis, sepal giant cell differentiation, megasporogenesis, microsporogenesis, anther wall tapetum development, and plant epidermal cell differentiation. The gene product localizes to the plasma membrane, membrane, multivesicular body membrane, and vacuolar lumen. Studies of related genes in other species link the family to broader roles in receptor kinase signaling and development.
