RLK — Medicago truncatula

Summary

MTR_7G062920 (MtRLK) encodes a transmembrane receptor serine/threonine kinase with a legume lectin domain, classified as an L-type lectin receptor kinase. It possesses 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 inhibition of salinity response, response to salt, and upregulation of innate immune response. The gene is also connected to cell death, cytokinin signaling, and regulation of growth. Overexpression studies associate MtRLK with salt tolerance and pathogen resistance. The protein 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 germination, seed weight, seed size, chlorophyll content, and root hair length.
