RLK — Hordeum vulgare subsp. vulgare

Summary

HORVU.MOREX.R3.5HG0513630 (HvRLK) encodes a transmembrane receptor protein serine/threonine kinase with histidine kinase activity, coreceptor activity, and sugar binding, belonging to the L-type lectin receptor kinase family. In barley, it is associated with pollen development and aperture formation, sporulation, regulation of developmental growth, immune and defense responses including defense against bacteria and oomycetes, response to heat, cytokinin and brassinosteroid signaling, virus-induced PTGS, inhibition of salinity response, and histidyl-aspartyl phosphorelay. The protein localizes to the plasma membrane, cytosol, and pollen aperture. It is also linked to stem rust. Studies of related genes in other species connect the family to additional signaling roles.
