ADH — Hordeum vulgare subsp. vulgare

Summary

HORVU.MOREX.R3.4HG0406790 (HvADH) on barley chromosome 4H encodes an alcohol dehydrogenase with S-nitrosoglutathione reductase, S-(hydroxymethyl)glutathione dehydrogenase, and aldo-keto reductase activities, along with calcium ion binding and protein homodimerization functions. The gene is associated with ethanol fermentation, activation of cellular response to hypoxic stress, methanal metabolism, pyruvate metabolism, and responses to hypoxia, flooding, hydrogen peroxide, sucrose, and estradiol. It localizes to the cytosol, plastid, mitochondria, nucleus, and plasmalemma. HvADH is linked to grain yield, grain dry weight, seed size, germination rate, protein content, photosynthetic rate, respiration rate, leaf senescence, drought tolerance, low temperature stress response, herbicide sensitivity, disease tolerance, and salt tolerance. Phenotypic associations include submergence tolerance, waterlogging tolerance, hypoxia tolerance, cold stress tolerance, flooding response, aldehyde detoxification, fermentation, and stomatal closure.
