HSD1 — Beta vulgaris subsp. vulgaris

Summary

BvHSD1 (HSD1) on sugar beet chromosome 1 encodes a short-chain dehydrogenase/reductase (SDR) family protein with estradiol 17-beta-dehydrogenase, 17-beta-hydroxysteroid dehydrogenase (NADP+), 11-beta-hydroxysteroid dehydrogenase (NAD+), and 3-oxoacyl-ACP reductase activities, and binds NAD and NADP. The gene is associated with responses to brassinosteroids, abscisic acid, and aldosterone, as well as steroid metabolism, steroidogenesis, fatty acid anabolism, keratinocyte proliferation, and inflammatory response. Its product localises to the oilbody, adiposome, membrane, cytosol, and extracellular region. BvHSD1 is linked to seed germination, pollen development, and male gametophyte viability. Studies of related genes in other species connect the family to salt stress tolerance, seed yield, seed dormancy, and plant growth.
