FER1 — Brassica napus

Summary

BnFER1 (FER1) on chromosome C03 of oilseed rape (Brassica napus) encodes a ferritin protein with ferroxidase activity and iron-binding capacity. The gene is associated with cellular and multicellular iron ion homeostasis, iron transport, and responses to iron, zinc, hydrogen peroxide, and bacteria. It is linked to photosynthetic electron transport, seed development, leaf senescence, cell cycle modulation, and miRNA processing. The protein localises to the thylakoid, chloroplast thylakoid membrane, chloroplast stroma, mitochondria, and cytoplasm. Associations with agronomic traits include seed weight, seed iron accumulation, zinc accumulation, lateral root density and development, and responses to cold and salt stress. Studies of related genes in other species connect the family to iron homeostasis, iron storage, lateral root emergence, disease resistance, and senescence.
