FSD1 — Beta vulgaris subsp. vulgaris

Summary

BvFSD1 (FSD1) on sugar beet chromosome 5 encodes a manganese/iron superoxide dismutase (Mn/Fe_SOD) family protein with superoxide dismutase activity, as well as RNA endonuclease activity, siRNA and miRNA binding, and calcium-dependent protein serine/threonine kinase activity. The gene is associated with removal of superoxide radicals, reactive oxygen species homeostasis, and detoxification pathways. It has been linked to numerous agronomic traits including biomass yield, seed yield and viability, leaf elongation rate, water use efficiency, transpiration rate, days to flowering, and responses to herbicides, light intensity, and carbon dioxide. Additional associations include auxin metabolism, unsaturated fatty acid and triglyceride anabolism, regulation of stomatal opening, floral organ abscission, and leaf pattern formation. The protein localizes to plastid nucleoids, chloroplasts, thylakoids, mitochondria, and the apoplast.
