FSD1 — Beta vulgaris subsp. vulgaris

Summary

BvFSD1 (FSD1) on sugar beet chromosome 7 encodes a superoxide dismutase with manganese/iron-binding domains, annotated with superoxide dismutase, siRNA/miRNA binding, RNA endonuclease, and protein kinase activities. The gene is associated with reactive oxygen species anabolism and removal of superoxide radicals, responses to light intensity, UV, copper, and zinc, and regulation of stomatal opening and transport. It is linked to plastid, chloroplast, mitochondrial, and thylakoid localizations. Traits connected to BvFSD1 include biomass yield, seed yield and viability, water use efficiency, transpiration rate, leaf elongation rate, days to flowering, IAA and jasmonic acid content, sucrose synthase activity, and responses to aphids, viruses, and osmotic stress. Phenotypes associated with the gene include oxidative stress tolerance, waterlogging tolerance, heat stress response, photosynthetic efficiency, chloroplast biogenesis, and root architecture.
