RLK — Brassica napus

Summary

BnRLK (DARMORV10_A05P08260.1) on chromosome A05 of oilseed rape encodes a transmembrane receptor serine/threonine kinase with lectin domains, belonging to the L-type lectin receptor kinase family. The protein possesses histidine kinase activity, coreceptor activity, sugar binding, and protein homodimerization activity, and is localized to the plasmalemma, ER, cytosol, and pollen aperture. This gene is associated with cell wall thickening, pollen aperture formation, stomatal closure, somatic embryogenesis, and regulation of developmental growth. It is linked to defense responses against oomycetes and fungi, immune response, response to chitin and salicylate, cell death, and inhibition of salinity response. Additionally, it is associated with cytokinin signaling, histidyl-aspartyl phosphorelay, and stress response. Studies of related genes in other species associate the family with drought tolerance.
