HVA1 — Hordeum vulgare subsp. vulgare

Summary

HVA1 (HORVU.MOREX.R3.4HG0408940) 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 response to thirst. It is associated with the nucleus. HVA1 has been connected to several agronomically important traits including drought tolerance, salinity tolerance, cold tolerance, heat tolerance, water use efficiency, seed dormancy, root length, chlorophyll content, relative chlorophyll content, soluble protein content, flavonoid content, and protein content. Studies of related genes in other species link the family to abiotic stress tolerance, cold stress tolerance, and ABA responsiveness, as well as shoot dry weight and leaf number.
