LYK3 — Medicago truncatula

Summary

MTR_5G086130 (LYK3) in barrel medic (Medicago truncatula) on chromosome 5 encodes a transmembrane receptor protein kinase with chitin-binding and protein tyrosine/serine/threonine kinase activities, belonging to the LysM_RLK3/10 and CERK1/LYK3-like families. The gene is associated with nitrogen fixation, response to symbiotic bacteria, response to chitin, detection of molecules of fungal origin, upregulation of defense response to oomycetes, endocytosis, vesicle localization, flower morphogenesis, regulation of leaf senescence, and various developmental processes including sepal giant cell differentiation, megasporogenesis, microsporogenesis, and anther wall tapetum development. It is also linked to membrane and plasmalemma localization. Studies of related genes in other species connect the family to traits such as root weight, nitrogen content, auxin content, leaf shape, salt response, and root length.
