HSD1 — Beta vulgaris subsp. vulgaris

Summary

BvHSD1 (BVRB_5G124740) on sugar beet chromosome Bvchr5_un.sca009 encodes a ketoreductase domain-containing protein with estradiol 17-beta-dehydrogenase, 17-beta-hydroxysteroid dehydrogenase, 11-beta-hydroxysteroid dehydrogenase, tropinone reductase, and 3-oxoacyl-ACP reductase activities, along with NAD(P) binding and redox activity. It is associated with steroid metabolism, steroidogenesis, tropane alkaloid anabolism, fatty acid anabolism, and responses to aldosterone, brassinosteroid, and abscisic acid. The gene is linked to embryogenesis, seed germination, pollen development, and male gametophyte viability. It localizes to the oilbody, adiposome, membrane, cytosol, and extracellular regions. Studies of related genes in other species connect the family to salt stress tolerance, salt tolerance, seed yield, seed dormancy, and plant growth.
