RLK — Hordeum vulgare subsp. vulgare

Summary

HORVU.MOREX.R3.5HG0518200 (HvRLK) on barley chromosome 5H encodes a transmembrane receptor protein serine/threonine kinase with a legume lectin domain, possessing histidine kinase activity, sugar binding, and signaling receptor activity. The gene is associated with diverse biological processes including sporulation, pollen aperture formation, pollen development, rejection of self pollen, defense response to fungi and oomycetes, immune response, detection of molecules of fungal origin, virus-induced PTGS, inhibition of salinity response, cytokinin and brassinosteroid-mediated signalling, response to heat, and protein autophosphorylation. It is linked to stem rust. The encoded protein localises to the membrane, plasmalemma, cytosol, and pollen aperture. Studies of related genes in other species connect the family to additional kinase functions.
