HVA1 — Hordeum vulgare subsp. vulgare

Summary

HVA1 (HORVU.MOREX.R3.1HG0080000) on barley chromosome 1H encodes a protein associated with protein storage and localised to the nucleus. The gene is associated with cold acclimation, response to cold, ABA signaling, stomatal closure, seed germination, embryogenesis, cell division, programmed cell death, and signal transduction. It is associated with several agronomically important traits including drought tolerance, cold tolerance, heat tolerance, salinity tolerance, water use efficiency, relative chlorophyll content, soluble protein content, flavonoid content, seed dormancy, protein content, and root length. Studies of related genes in other species link the family to abiotic stress tolerance, cold and osmotic stress tolerance, salt tolerance, ABA responsiveness, and traits such as grain weight, plant height, spike length, and coleoptile length.
