HVA22 — Hordeum vulgare subsp. vulgare

Summary

HORVU.MOREX.R3.7HG0674710 (symbol HVA22, also known as HvENS-122) on barley chromosome 7H encodes a TB2_DP1_HVA22 domain-containing protein. This gene is associated with the regulation of autophagy, protein storage, secretion, programmed cell death, ABA signaling, stomatal closure, and fruit development. It has been linked to seed germination, as well as flavonoid and chlorophyll content. The encoded protein localises to the ER, Golgi complex, and membrane. Studies of related genes in other species connect the HVA22 family to grain yield, seed weight, protein content, quality traits, and low-temperature stress response, including cold stress tolerance.
