ADH — Oryza sativa Indica Group

Summary

BGIOSGA009283 (symbol ADH, preferred name OiADH) on chromosome 2 of Indica rice encodes an alcohol dehydrogenase family protein with S-(hydroxymethyl)glutathione dehydrogenase (NAD+, NADP+) and S-nitrosoglutathione reductase (NADH) activities, as well as aldo-keto reductase and redox activity. The gene is associated with responses to hypoxia, flooding, hydrogen peroxide, heat acclimation, and osmotic and salinity stress, and with seed development, programmed cell death, and the MAPK cascade. It has been linked to traits including respiration rate, herbicide sensitivity, low temperature stress response, photosynthetic rate, leaf senescence, disease tolerance, plant height, salt tolerance, and drought tolerance. The encoded protein localizes to plastids, mitochondria, the cytosol, the nucleus, and the plasmalemma. Studies of related genes in other species link the family to low oxygen tolerance, freezing tolerance, drought resistance, and formaldehyde detoxification.
