RLK — Hordeum vulgare subsp. vulgare

Summary

HORVU.MOREX.R3.7HG0648470 (HvRLK) on barley chromosome 7H encodes a transmembrane receptor protein serine/threonine kinase with lectin domains, possessing histidine kinase activity, coreceptor activity, sugar binding, and protein homodimerization activity. The gene is associated with diverse biological processes including sporulation, pollen aperture formation, regulation of developmental growth, histidyl-aspartyl phosphorelay, virus-induced PTGS, upregulation of innate immune response, inhibition of salinity response, somatic embryogenesis, cytokinin and brassinosteroid mediated signalling, regulation of defence response to fungi, defence response to oomycetes, immune response, pollen development, protein autophosphorylation, and response to heat. It is linked to stem rust and localises to the pollen aperture, cytosol, and plasmalemma. Studies of related genes in other species link the family to immune signalling and brassinosteroid perception.
