RLK — Brassica napus

Summary

BnRLK (DARMORV10_A03P20820.1) on chromosome A03 of oilseed rape encodes a transmembrane receptor serine/threonine kinase with lectin domains, possessing histidine kinase activity, sugar binding, and coreceptor activity. The gene is associated with cell wall thickening, pollen aperture formation, stomatal closure, embryogenesis, and stress responses including defense against oomycetes and response to chitin. It is linked to cytokinin and ABA signaling, salicylate response, immune response, cell death, and inhibition of salinity response. The encoded protein localizes to the pollen aperture, endoplasmic reticulum, extracellular region, cytosol, and plasmalemma. Studies of related genes in other species link the family to drought tolerance and other stress-related traits.
