RLK — Beta vulgaris subsp. vulgaris

Summary

BvRLK (BVRB_7G173340) on sugar beet chromosome 7 encodes a transmembrane receptor serine/threonine kinase with histidine kinase activity, sugar binding, and ATP binding, belonging to the L-type lectin receptor kinase family. The gene is associated with diverse biological processes including defense responses to bacteria, fungi, oomycetes, and other organisms, immune response, response to salicylate, cytokinin signaling, abscission, pollen aperture formation and development, cellular salinity response and its inhibition, histidyl-aspartyl phosphorelay, and protein phosphorylation and autophosphorylation. It is linked to phenotypes such as defense against herbivory and methyl jasmonate-mediated stomatal closure. The protein localizes to the plasma membrane, membrane, extracellular region, ER, cytosol, nucleus, and pollen aperture. Studies of related genes in other species connect the family to traits including drought tolerance, salt response, root volume, fruit size, and resistance to Fusarium crown rot and Pseudomonas syringae.
