RLK — Hordeum vulgare subsp. vulgare

Summary

HORVU.MOREX.R3.4HG0403960 (symbol HvRLK) on barley chromosome 4H encodes a transmembrane receptor protein serine/threonine kinase with a legume lectin domain, possessing histidine kinase activity, sugar binding, and protein kinase activity. It is associated with diverse biological processes including defense responses to bacteria, oomycetes, and other organisms, immune response, heat response, cytokinin and brassinosteroid-mediated signaling, pollen development and aperture formation, sporulation, virus-induced PTGS, and inhibition of salinity response. The product localizes to the membrane, plasmalemma, cytosol, and pollen aperture. The gene is also linked to stem rust trait. Studies of related genes in other species connect the family to additional stress signaling roles.
