RLK — Brassica napus

Summary

BnRLK (DARMORV10_C03P24480.1) on chromosome C03 of oilseed rape encodes a transmembrane receptor serine/threonine kinase with a legume lectin domain, possessing histidine kinase activity, sugar binding, and protein homodimerization activity. This gene is associated with cell wall thickening, pollen aperture formation and development, stomatal closure, embryogenesis, stress and immune responses, defense against oomycetes, cytokinin and ABA signaling, response to chitin and salicylate, cell death, and inhibition of salinity response. It localizes to the pollen aperture, endoplasmic reticulum, extracellular region, cytosol, and plasmalemma. The gene is also linked to stomatal resistance. Studies of related genes in other species connect the family to drought tolerance and other traits.
