RLK — Hordeum vulgare subsp. vulgare

Summary

HORVU.MOREX.R3.6HG0623130 (HvRLK) on barley chromosome 6H encodes a transmembrane receptor protein serine/threonine kinase with a legume lectin domain, classified as an L-type lectin receptor kinase. The product exhibits histidine kinase activity, coreceptor activity, sugar binding, and protein homodimerization activity, and localizes to the plasma membrane, cytosol, and pollen aperture. This gene is associated with diverse biological processes including sporulation, pollen aperture formation, pollen development, somatic embryogenesis, cytokinin and brassinosteroid-mediated signaling, regulation of growth, immune response, defense against fungi and oomycetes, virus-induced PTGS, inhibition of salinity response, and response to heat. It is also linked to stem rust. Studies of related genes in other species connect the family to immune signaling and stress responses.
