ASD — Oryza sativa Japonica

Summary

OsASD (OS12G0260500) in rice encodes a member of the short-chain dehydrogenase/reductase (SDR) family with NAD(P)-binding domain, exhibiting momilactone-A synthase, (+)-borneol dehydrogenase, xanthoxin dehydrogenase (NAD+), and aldo-keto reductase (NAD) activities. The gene is associated with abscisic acid and gibberellin biosynthesis, monoterpenoid and terpenoid anabolism, alanine and sucrose anabolism, ethanol fermentation, aerobic respiration, and detoxification. It has been linked to pre-harvest sprouting, seed dormancy, germination rate, vivipary, seed shattering, hull and pericarp color, stem elongation, plant height, grain yield, protein content, and salinity tolerance. The encoded protein localizes to mitochondria and the cytosol. Related genes in other species link the family to alcohol dehydrogenase and tropinone reductase activities.
