RLK — Brassica oleracea

Summary

BoRLK (BOLC102_C04P010700.1) on cabbage chromosome 4 encodes a transmembrane receptor serine/threonine kinase with an L-type lectin domain, possessing histidine kinase activity, coreceptor activity, sugar binding, and protein homodimerization activity. It is associated with multiple biological processes including calcium and cytokinin signaling, the histidyl-aspartyl phosphorelay, pollen aperture formation and development, somatic embryogenesis, immune and defense responses to oomycetes and fungi, regulation of growth and developmental growth, inhibition of salinity response, response to salicylate, glucosinolate and amino acid anabolism, and homeostasis. The protein localizes to the plasma membrane, extracellular region, ER, cytosol, and pollen aperture. Studies of related genes in other species link the family to drought tolerance and stomatal resistance.
