RLK — Hordeum vulgare subsp. vulgare

Summary

HORVU.MOREX.R3.5HG0523910 (HvRLK) on barley chromosome 5H encodes a non-specific serine/threonine protein kinase belonging to the L-type lectin receptor kinase family, with transmembrane receptor serine/threonine kinase activity, histidine kinase activity, coreceptor activity, sugar binding, and protein homodimerization activity. The gene is associated with diverse biological processes including sporulation, pollen aperture formation, pollen development, somatic embryogenesis, cytokinin and brassinosteroid-mediated signalling, regulation of growth, immune response, defence responses to bacteria, fungi, and oomycetes, virus-induced PTGS, inhibition of salinity response, response to heat, and protein autophosphorylation. It is linked to stem rust trait and localises to the pollen aperture, cytosol, and plasmalemma. Studies of related genes in other species connect the family to similar signalling and stress responses.
