RLK — Medicago truncatula

Summary

MTR_7G062890, also known as MtRLK or MtLPK1, encodes a transmembrane receptor serine/threonine kinase with a legume lectin domain, classified as an L-type lectin receptor kinase. The gene product possesses protein kinase, histidine kinase, and sugar-binding activities, and is annotated with coreceptor activity. In barrel medic, MtRLK is associated with nitrogen fixation, lateral root development, somatic embryogenesis, organogenesis, pollen aperture formation, and the regulation of growth and immune responses. It is linked to defense against oomycetes and fungi, response to salt and salicylate, cell death, and inhibition of the salinity response. The protein localizes to the plasma membrane, endoplasmic reticulum, cytosol, and extracellular space. Overexpression studies connect MtRLK to enhanced salt tolerance and pathogen resistance. Studies of related genes in other species link the family to seed germination.
