HSD1 — Beta vulgaris subsp. vulgaris

Summary

BvHSD1 (BVRB_5G126480) on sugar beet chromosome Bvchr5_un.sca023 encodes a short-chain dehydrogenase/reductase (SDR) family protein with estradiol 17-beta-dehydrogenase, 11-beta-hydroxysteroid dehydrogenase, secoisolariciresinol dehydrogenase and 3-oxoacyl-ACP reductase activities, and binds NAD(P). The gene is associated with steroid metabolism, lignan and phenylpropanoid anabolism, fatty acid anabolism, and responses to brassinosteroid, abscisic acid, jasmonic acid, UV and wounding. It has been linked to embryogenesis, seed germination, pollen development and male gametophyte viability. The protein localises to the cytosol, membrane, mitochondria, oil body and extracellular space. Studies of related genes in other species connect the family to salt stress tolerance, seed yield, seed dormancy and plant growth.
