RLK — Hordeum vulgare subsp. vulgare

Summary

HORVU.MOREX.R3.2HG0131680, designated HvRLK on barley chromosome 2H, encodes a transmembrane receptor serine/threonine kinase with a legume lectin domain, possessing histidine kinase activity, coreceptor activity, sugar binding, and signaling receptor activity. This gene is associated with diverse biological processes including sporulation, pollen aperture formation, defense response to oomycetes, immune response, cytokinin signaling, response to salicylate, and inhibition of salinity response. It has been linked to stem rust and growth phenotypes. The encoded protein localizes to the plasmalemma, pollen aperture, endoplasmic reticulum, plant-type vacuole, mitochondria, cytosol, and nucleus. Studies of related genes in other species connect the family to salt tolerance, drought tolerance, grain yield, cold tolerance, stomatal immunity, and resistance to Pseudomonas syringae.
