RLK — Medicago truncatula

Summary

MTR_7G062950 (MtRLK) encodes a transmembrane receptor protein serine/threonine kinase with lectin domains, belonging to the L-type lectin receptor kinase family. The gene product exhibits coreceptor activity, histidine kinase activity, sugar binding, and protein homodimerization activity. MtRLK is associated with nitrogen fixation, lateral root development, somatic embryogenesis, organogenesis, pollen aperture formation, and ectodomain cleavage. It is linked to defense responses against oomycetes and fungi, immune response, upregulation of innate immune response, inhibition of salinity response, response to salt and salicylate, cell death, and regulation of growth. The protein localizes to the plasmalemma, endoplasmic reticulum, cytosol, extracellular region, and pollen aperture. Overexpression studies connect MtRLK to salt tolerance and pathogen resistance. Studies of related genes in other species link the family to seed germination.
