RLK — Medicago truncatula

Summary

MTR_7G062660 (MtRLK) encodes a transmembrane receptor protein serine/threonine kinase with lectin domains, classified as an L-type lectin receptor kinase. It exhibits coreceptor activity, histidine kinase activity, sugar binding, and protein homodimerization activity. In barrel medic, MtRLK is associated with nitrogen fixation, lateral root development, somatic embryogenesis, organogenesis, pollen aperture formation, and defense responses to oomycetes and fungi. It is linked to the regulation of growth, cell death, immune response, and inhibition of salinity response. The gene has been connected to salt tolerance and pathogen resistance, particularly in overexpression contexts. MtRLK localizes to the plasma membrane, endoplasmic reticulum, cytosol, extracellular region, and pollen aperture. Studies of related genes in other species link the family to seed weight, seed size, chlorophyll content, root hair length, proline content, and disease tolerance.
