RLK — Hordeum vulgare subsp. vulgare

Summary

HORVU.MOREX.R3.1HG0038630 (HvRLK) encodes a transmembrane receptor protein serine/threonine kinase with lectin domains, exhibiting histidine kinase activity, sugar binding, and protein homodimerization activity. This barley gene on chromosome 1H is associated with sporulation, pollen aperture formation, somatic embryogenesis, regulation of developmental growth, cytokinin signaling, and immune response. It is linked to defense response to fungi and oomycetes, response to salicylate, virus-induced PTGS, inhibition of salinity response, and response to heat. The protein localizes to the plasmalemma, ER, nucleus, mitochondria, cytosol, plant-type vacuole, and pollen aperture. HvRLK is associated with stem rust and growth-related phenotypes. Studies of related genes in other species connect the family to salt tolerance, stomatal immunity, ethylene homeostasis, and traits including grain yield, plant height, drought tolerance, and cold tolerance.
