RLK — Brassica napus

Summary

BnRLK (DARMORV10_C04P10220.1) on chromosome C04 of oilseed rape encodes a transmembrane receptor serine/threonine kinase with lectin domains, belonging to the L-type lectin receptor kinase family. The protein exhibits histidine kinase activity, coreceptor activity, sugar binding, and protein homodimerization activity, and localizes to the plasma membrane, endoplasmic reticulum, cytosol, and pollen aperture. This gene is associated with cell wall thickening, pollen aperture formation, stomatal closure, embryogenesis, somatic embryogenesis, immune and defense responses to oomycetes and fungi, response to chitin and salicylate, cytokinin signaling, regulation of developmental growth, inhibition of salinity response, and cell death. It is also linked to stomatal resistance. Studies of related genes in other species connect the family to drought tolerance.
