RLK — Brassica oleracea

Summary

BoRLK (BOLC102_C03P025890.1) on cabbage chromosome 3 encodes a transmembrane receptor serine/threonine kinase with a legume lectin domain, belonging to the L-type lectin receptor kinase family. It has histidine kinase activity, coreceptor activity, sugar binding, and protein homodimerization activity. The gene is associated with diverse biological processes including immune response, defense against oomycetes and bacteria, pollen aperture formation and development, calcium and cytokinin signaling, brassinosteroid-mediated signaling, response to heat and salicylate, inhibition of salinity response, and regulation of developmental growth. It localizes to the plasmalemma, extracellular region, ER, cytosol, and pollen aperture. Studies of related genes in other species link the family to drought tolerance and stomatal resistance.
