RLK — Hordeum vulgare subsp. vulgare

Summary

HORVU.MOREX.R3.6HG0590590 (HvRLK) encodes a transmembrane receptor serine/threonine kinase with a legume lectin domain, exhibiting histidine kinase activity, sugar binding, and protein homodimerization activity. This barley gene on chromosome 6H is associated with immune and defense responses, including defense against bacteria, oomycetes, and other organisms, as well as response to heat. It is linked to pollen development and aperture formation, sporulation, and regulation of developmental growth. The gene is connected to cytokinin and brassinosteroid-mediated signaling, histidyl-aspartyl phosphorelay, virus-induced PTGS, and inhibition of salinity response. Its product localizes to the plasma membrane, cytosol, and pollen aperture. HvRLK has also been associated with stem rust. Studies of related genes in other species link the family to additional signaling roles.
