FSD1 — Capsicum annuum

Summary

CaFSD1 (T459_15098) on pepper chromosome 5 encodes a member of the Fe/Mn superoxide dismutase family with superoxide dismutase activity (EC 1.15.1.1), along with annotated RNA endonuclease, siRNA/miRNA binding, and calcium-dependent protein serine/threonine kinase activities. The gene is associated with reactive oxygen species homeostasis, removal of superoxide radicals, detoxification, and the ascorbate-glutathione cycle. It is linked to heat dissipation, carotenoid metabolism, dopamine metabolism, and regulation of hormone levels. Associations with agronomic traits include leaf area index, root volume, biomass yield, seed yield, net photosynthetic rate, pungency, and responses to viral disease and aphids. Localisation evidence connects the product to chloroplasts, thylakoids, plastid nucleoids, and mitochondria. Related genes in other species are linked to oxidative stress tolerance, redox homeostasis, and responses to copper deficiency, uranium stress, and waterlogging.
