RLK — Medicago truncatula

Summary

MTR_7G062680, designated MtRLK, encodes a transmembrane receptor protein serine/threonine kinase with lectin domains, belonging to the L-type lectin receptor kinase family. The gene product possesses coreceptor activity, histidine kinase activity, sugar binding, and protein homodimerization activity, and is localized to the plasmalemma, ER, cytosol, and pollen aperture. 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. Overexpression studies link MtRLK to salt tolerance and pathogen resistance. Related genes in other species are associated with seed germination.
