RLK — Beta vulgaris subsp. vulgaris

Summary

BVRB_2G025270 (BvRLK) encodes a transmembrane receptor serine/threonine kinase with histidine kinase activity and sugar-binding capacity, belonging to the L-type lectin receptor kinase family. In sugar beet, this gene is associated with diverse biological processes including defense responses to bacteria, fungi, and oomycetes, immune response, cytokinin and brassinosteroid signaling, ethylene sensitivity, pollen development and aperture formation, self-pollen rejection, abscission, and cellular salinity response. It is linked to regulation of developmental growth, protein phosphorylation and autophosphorylation, and histidyl-aspartyl phosphorelay. The encoded protein localizes to the plasma membrane, endoplasmic reticulum, cytosol, nucleus, and extracellular region. Studies of related genes in other species connect the family to traits such as drought tolerance, salt response, root volume, fruit size, lycopene content, and resistance to Fusarium crown rot and Pseudomonas syringae.
