RLK — Medicago truncatula

Summary

MTR_7G062900, designated MtRLK, encodes a transmembrane receptor serine/threonine kinase with a legume lectin domain, classifying it as an L-type lectin receptor kinase. The gene product possesses coreceptor, histidine kinase, and sugar-binding activities, and is localized to the plasma membrane, endoplasmic reticulum, and pollen aperture. MtRLK is associated with nitrogen fixation, lateral root development, somatic embryogenesis, organogenesis, and pollen aperture formation. It is linked to defense responses against oomycetes and fungi, immune response regulation, cell death, and inhibition of the salinity response. Associations with salt tolerance and pathogen resistance have been observed in overexpression contexts. Related genes in other species are linked to seed germination.
