RLK — Hordeum vulgare subsp. vulgare

Summary

HORVU.MOREX.R3.2HG0131770 (HvRLK) on barley chromosome 2H encodes a protein with a legume lectin domain and a serine/threonine kinase domain, and is annotated with histidine kinase activity, sugar binding, and protein homodimerization activity. This gene is associated with sporulation, pollen aperture formation, cytokinin signaling, immune response, regulation of defence response to fungi, defense response to oomycetes, response to heat and salicylate, and inhibition of salinity response. It is linked to stem rust and growth. The protein localizes to the plasmalemma, pollen aperture, endoplasmic reticulum, plant-type vacuole, mitochondria, cytosol, and nucleus. Related genes in other species are associated with salt tolerance, stomatal immunity, ethylene homeostasis, and resistance to Pseudomonas syringae, as well as traits including grain yield, drought tolerance, plant height, and cold tolerance.
