RLK — Hordeum vulgare subsp. vulgare

Summary

HORVU.MOREX.R3.7HG0746230, designated HvRLK (also known as HvRDK1 or RDK1) on barley chromosome 7H, encodes a transmembrane receptor serine/threonine kinase with leucine-rich repeats, exhibiting protein kinase activity, steroid binding, SNARE binding, and histone H2AS1 kinase activity. The gene is associated with sporulation, upregulation of seed germination, floral organ development, regulation of meristem organization, cellular response to drought, activation of salinity response, detection of brassinosteroid stimulus, and regulation of stomatal complex development. It is linked to stem rust and ABA response phenotypes. Studies of related genes in other species connect the family to grain yield, plant height, spikelet density, drought tolerance, chlorophyll content, anthesis time, and root morphology traits.
