ASD — Oryza sativa Indica Group

Summary

BGIOSGA026334 (ASD) in Indica rice encodes a member of the short-chain dehydrogenase/reductase (SDR) family with NAD(P)-binding domain, exhibiting zerumbone synthase, momilactone-A synthase, (+)-borneol dehydrogenase, xanthoxin dehydrogenase, and aldo-keto reductase activities. The gene is associated with abscisic acid and terpenoid biosynthesis, the MAPK cascade, seed maturation, and monoterpenoid and (+)-camphor anabolism. Its product localizes to mitochondria and cytosol. ASD has been linked to submergence tolerance, seed dormancy, plant height, and grain yield. Studies of related genes in other species connect the SDR family to alcohol dehydrogenase and tropinone reductase-like functions, as well as EC 1.1.1.326, 1.1.1.295, 1.1.1.198, and 1.1.1.1 activities.
