HVA1 — Hordeum vulgare subsp. vulgare

Summary

HORVU.MOREX.R3.1HG0079980 (HVA1) on barley chromosome 1H encodes a protein associated with late embryogenesis abundant (LEA) family members, specifically linked to LEA19. The gene is annotated to biological processes including protein storage, stomatal closure, cold acclimation, ABA signaling, seed germination, programmed cell death, and response to thirst. It localises to the nucleus. HVA1 is associated with several agronomically important traits, including drought tolerance, salinity tolerance, cold tolerance, heat tolerance, water use efficiency, seed dormancy, root length, relative chlorophyll content, soluble protein content, flavonoid content, and protein content. The gene is also connected to responses to cold temperature and abiotic stimuli. Studies of related genes in other species, linked by sequence similarity, associate the family with shoot dry weight.
