RLK — Medicago truncatula

Summary

MTR_7G062700 (MtRLK) encodes a transmembrane receptor serine/threonine kinase with a legume lectin domain, 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, cell death, inhibition of salinity response, and response to salt and salicylate. The protein localizes to the plasma membrane, endoplasmic reticulum, cytosol, and extracellular region. Overexpression studies connect MtRLK to salt tolerance and pathogen resistance. Related genes in other species link the family to seed germination.
