ASD — Beta vulgaris subsp. vulgaris

Summary

BvASD (BVRB_7G158510) encodes a short-chain dehydrogenase/reductase (SDR) family protein with NAD(P)-binding domain, exhibiting momilactone-A synthase, (+)-borneol dehydrogenase, secoisolariciresinol dehydrogenase, and xanthoxin dehydrogenase activities, along with aldo-keto reductase, nucleotide-binding, copper-binding, and redox activities. In sugar beet, BvASD is associated with abscisic acid (ABA) biosynthesis, sugar signaling, and responses to wounding, heat, UV, jasmonic acid, and bacterial defense. It is linked to traits including photosynthetic rate, amino acid content, and ethylene sensitivity, and to phenotypes such as seed dormancy, germination, drought tolerance, stomatal closure, and resistance to Botrytis cinerea. The gene product localizes to the cytosol, nucleus, mitochondria, and stress granules. Studies of related genes in other species connect the family to ABA biosynthesis, sugar sensitivity, and pathogen resistance.
