RLK — Beta vulgaris subsp. vulgaris

Summary

BvRLK (BVRB_6G150070) on sugar beet chromosome 6 encodes a transmembrane receptor protein serine/threonine kinase with lectin domains, belonging to the L-type lectin receptor kinase family. It possesses histidine kinase activity, coreceptor activity, sugar binding, and protein homodimerization activity. The gene is associated with diverse biological processes including pollen aperture formation and development, somatic embryogenesis, abscission, cell differentiation, regulation of developmental growth, and responses to ethylene, cytokinin, and salicylate. It is linked to immune response, defence against oomycetes and fungi, upregulation of innate immunity, and both cellular salinity response and inhibition of salinity response. The encoded protein localizes to the plasma membrane, endoplasmic reticulum, cytosol, nucleus, and extracellular region. Associations with ethylene sensitivity, defence against herbivory, and methyl jasmonate-mediated stomatal closure have also been noted.
