RLK — Medicago truncatula

Summary

MTR_7G062730, designated MtRLK, encodes a transmembrane receptor protein serine/threonine kinase belonging to the L-type lectin receptor kinase family. The product exhibits histidine kinase activity, sugar binding, SNARE binding, steroid binding, and signaling receptor activity. In barrel medic, MtRLK is associated with nitrogen fixation, lateral root development, organogenesis, defense response to oomycetes, immune response, cytokinin and brassinosteroid signaling, inhibition of salinity response, and response to salt and salicylate. It localizes to the plasma membrane, endosome, endoplasmic reticulum, and extracellular region. Overexpression of LPK1 is linked to salt tolerance and pathogen resistance. Related genes in other species are linked to seed germination, seed weight, seed size, chlorophyll content, root hair length, proline content, and disease tolerance.
