HVA1 — Hordeum vulgare subsp. vulgare

Summary

HVA1 (HORVU.MOREX.R3.4HG0408930) on barley chromosome 4H encodes a protein associated with cold acclimation and stress responses. The gene is linked to protein storage, stomatal closure, ABA signaling, seed germination, embryogenesis, programmed cell death, and signal transduction, with the product localizing to the nucleus. HVA1 is associated with several agronomically important traits, including drought tolerance, salinity tolerance, cold tolerance, heat 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 stress tolerance, and ABA responsiveness.
