HVA22 — Hordeum vulgare subsp. vulgare

Summary

HORVU.MOREX.R3.5HG0485770, also known as HVA22, is a barley gene on chromosome 5H that encodes a TB2_DP1_HVA22 domain-containing protein. In barley, this gene is associated with the regulation of autophagy, protein storage, secretion, programmed cell death, ABA signaling, and stomatal closure. It has also been linked to fruit development, embryogenesis, and response to thirst. The encoded protein localises to the endoplasmic reticulum, Golgi complex, and membrane. Additionally, HVA22 is associated with flavonoid content, chlorophyll content, and seed germination. Studies of related genes in other species link the HVA22 family to grain yield, relative yield, spikelet fertility, seed weight, protein content, and quality traits.
