RLK — Hordeum vulgare subsp. vulgare

Summary

HORVU.MOREX.R3.2HG0211310 (HvRLK) encodes a non-specific serine/threonine protein kinase belonging to the L-type lectin receptor kinase family, with transmembrane receptor protein serine/threonine kinase activity, histidine kinase activity, coreceptor activity, sugar binding, and protein homodimerization activity. This barley gene on chromosome 2H is associated with sporulation, pollen aperture formation and development, regulation of developmental growth and growth, somatic embryogenesis, immune response, defense response to oomycetes and fungi, virus-induced PTGS, upregulation of innate immune response, inhibition of salinity response, cytokinin and brassinosteroid mediated signaling, response to heat, protein phosphorylation and autophosphorylation, and histidyl-aspartyl phosphorelay. It is localized to the pollen aperture, cytosol, and plasmalemma. The gene is also linked to stem rust. Studies of related genes in other species, including BAK1, SIT1, SIT2, SERL2, CHARK, and DAF1, connect the family to similar signaling and stress response functions.
