RLK — Hordeum vulgare subsp. vulgare

Summary

HORVU.MOREX.R3.2HG0183940 (HvRLK) encodes a transmembrane receptor protein serine/threonine kinase with a legume lectin domain, classified as an L-type lectin receptor kinase. It exhibits histidine kinase activity, coreceptor activity, sugar binding, and protein homodimerization activity. The gene is associated with diverse biological processes including sporulation, pollen aperture formation and development, regulation of developmental growth, cytokinin and brassinosteroid-mediated signalling, immune and defense responses against bacteria, oomycetes, and heat, as well as virus-induced PTGS and inhibition of salinity response. It localizes to the pollen aperture, cytosol, and plasmalemma. HvRLK is also linked to stem rust. Studies of related genes in other species connect the family to additional signalling and stress responses.
