RLK — Beta vulgaris subsp. vulgaris

Summary

BvRLK (BVRB_7G173390) on sugar beet chromosome 7 encodes a protein with an L-type lectin receptor kinase domain, a legume lectin domain, a ConA-like domain superfamily, a protein kinase domain, and a kinase-like domain superfamily. It exhibits histidine kinase activity, sugar binding, transmembrane receptor protein serine/threonine kinase activity, kinase activity, protein serine kinase activity, protein kinase activity, protein serine/threonine kinase activity, protein homodimerization activity, and ATP binding. The gene is associated with pollen aperture formation, cellular response to ethene stimulus, histidyl-aspartyl phosphorelay, cellular salinity response, inhibition of salinity response, abscission, upregulation of innate immune response, somatic embryogenesis, regulation of growth, regulation of defence response to fungi, defense response to oomycetes, cytokinin signaling, immune response, response to salicylate, response to other organism, cell differentiation, protein phosphorylation, and pollen development. It localizes to the pollen aperture, endoplasmic reticulum, extracellular region, cytosol, plasmalemma, and nucleus. BvRLK is linked to ethylene sensitivity, defense response against herbivory, and methyl jasmonate-mediated stomatal closure. Related genes in other species link the family to stomatal immunity and resistance to Pseudomonas syringae, and to Fusarium crown and root rot resistance.
