RLK — Beta vulgaris subsp. vulgaris

Summary

BvRLK (BVRB_6G150100) 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 has coreceptor activity, histidine kinase activity, sugar binding, and protein homodimerization activity. The gene is associated with pollen aperture formation and development, rejection of self-pollen, abscission, defense responses to oomycetes, bacteria, and fungi, immune response, response to salicylate, and cellular responses to ethylene and salinity. It localizes to the plasma membrane, endoplasmic reticulum, nucleus, cytosol, and extracellular region. BvRLK is linked to ethylene sensitivity, defense against herbivory, and methyl jasmonate-mediated stomatal closure. Studies of related genes in other species connect the family to drought tolerance, salt response, root and shoot biomass, fruit size, lycopene content, self-incompatibility, and resistance to Fusarium crown rot and Pseudomonas syringae.
