RLK — Hordeum vulgare subsp. vulgare

Summary

HORVU.MOREX.R3.3HG0235770 (HvRLK) on barley chromosome 3H encodes a transmembrane receptor protein serine/threonine kinase with a legume lectin domain, exhibiting histidine kinase activity, sugar binding, and coreceptor activity. The gene is associated with immune response, defense against bacteria and oomycetes, and response to heat. It has been linked to stem rust, as well as pollen development and aperture formation, sporulation, and regulation of developmental growth. The encoded protein localizes to the plasma membrane, cytosol, and pollen aperture. It is also associated with cytokinin and brassinosteroid-mediated signaling, histidyl-aspartyl phosphorelay, inhibition of salinity response, and virus-induced post-transcriptional gene silencing. Studies of related genes in other species link the family to additional signaling receptor functions.
