ASD — Sorghum bicolor

Summary

SORBI_3006G065300 (ASD, also known as SbABA2) on sorghum chromosome 6 encodes a momilactone A synthase, a short-chain dehydrogenase/reductase (SDR) family protein with multiple oxidoreductase activities, including xanthoxin dehydrogenase, zerumbone synthase, and secoisolariciresinol dehydrogenase activities. The gene is associated with abscisic acid biosynthesis, terpenoid and phenylpropanoid biosynthesis, and responses to UV, jasmonic acid, and wounding. It has been linked to seed dormancy, seed germination, and sprouting tolerance. The encoded protein localizes to the mitochondria and cytosol. Studies of related genes in other species connect the SDR family to similar oxidoreductase functions and terpenoid metabolism.
