RLK (HORVU.MOREX.R3.2HG0211290) — Hordeum vulgare subsp. vulgare

Summary

HORVU.MOREX.R3.2HG0211290, designated HvRLK on barley chromosome 2H, encodes a non-specific serine/threonine protein kinase with a legume lectin domain, classifying it as an L-type lectin receptor kinase. The gene is associated with transmembrane receptor serine/threonine kinase activity, histidine kinase activity, coreceptor activity, sugar binding, and protein homodimerization. It has been linked to diverse biological processes including immune and defense responses against bacteria, oomycetes, and other organisms, as well as cytokinin and brassinosteroid-mediated signaling, pollen development and aperture formation, sporulation, inhibition of salinity response, virus-induced PTGS, and response to heat. The product localizes to the plasma membrane, cytosol, and pollen aperture. Additionally, HvRLK is associated with stem rust. Studies of related genes in other species connect the family to immune signaling and stress responses.
