RLK — Medicago truncatula

Summary

MTR_7G062850, designated MtRLK, encodes a transmembrane receptor protein serine/threonine kinase with a leguminous lectin domain and sugar-binding activity. In barrel medic, this gene is associated with nodulation, nitrogen fixation, lateral root development, organogenesis, pollen aperture formation, pollen development, cell division, root development, protein phosphorylation and autophosphorylation, ectodomain cleavage, defense response to oomycetes, response to salt, inhibition of salinity response, response to symbiotic fungi, response to salicylate, and cell death. It localizes to the pollen aperture, endoplasmic reticulum, extracellular region, cytosol, and plasmalemma. Overexpression studies link MtRLK to salt tolerance and pathogen resistance. Studies of a related gene in another species connect the family to seed germination. Sequence similarity further links the family to traits including seed weight, seed size, chlorophyll content, root hair length, proline content, and salt tolerance.
