ADH1 — Oryza sativa Indica Group

Summary

BGIOSGA026336 (ADH1) on chromosome 7 of indica rice encodes an uncharacterized protein that belongs to the short-chain dehydrogenase/reductase (SDR) family and contains an NAD(P)-binding domain. The enzyme exhibits multiple oxidoreductase activities, including zerumbone synthase, momilactone-A synthase [NAD(P)H], secoisolariciresinol dehydrogenase, (+)-borneol dehydrogenase, and xanthoxin dehydrogenase (NAD+) activities, along with aldo-keto reductase and general redox activity. This gene is associated with the biosynthesis of terpenoids, lignans, abscisic acid, and (+)-camphor, as well as the MAPK cascade. The encoded protein localizes to the cytosol. ADH1 is linked to submergence tolerance and plant height. Studies of related genes in other species further connect the SDR family to seed germination and protein content.
