HvPKABA1 — Hordeum vulgare subsp. vulgare

Summary

HvPKABA1, located on barley chromosome 2H, encodes a protein serine/threonine kinase (EC 2.7.11.1) with ATP-binding and kinase domains. The gene is associated with abscisic acid (ABA) signaling, seed germination, seedling development, protein phosphorylation, and signal transduction. It has been linked to protein storage, responses to salinity and abiotic stimuli, and the expression of OsSAPK1. The encoded protein localizes to the cytosol, cytoplasm, and nucleus. The gene is associated with drought response. Related genes in other species are linked to root growth and abiotic stress tolerance. Sequence similarity evidence further associates the family with traits including drought tolerance, heat tolerance, chlorophyll content, root thickness, flavonoid content, proline content, and black point incidence in Fusarium.
