RLK — Hordeum vulgare subsp. vulgare

Summary

HORVU.MOREX.R3.6HG0598520 (HvRLK) encodes a receptor-like kinase with a legume lectin domain, possessing transmembrane receptor serine/threonine kinase activity, histidine kinase activity, and sugar binding. This barley gene on chromosome 6H is associated with immune responses, including defence against bacteria, fungi, and oomycetes, as well as virus-induced PTGS and upregulation of innate immunity. It is linked to pollen development and aperture formation, sporulation, somatic embryogenesis, regulation of growth, and responses to heat. The gene is also connected to cytokinin and brassinosteroid-mediated signalling, protein autophosphorylation, and stem rust. The encoded protein localises to the membrane, plasmalemma, cytosol, and pollen aperture. Studies of related genes in other species link the family to additional signalling roles.
