FER3 — Glycine max

Summary

GLYMA_18G205800V4, designated GmFER3, encodes a ferritin protein containing ferritin-like and ferritin DPS domains, with ferroxidase activity and the ability to bind ferrous and ferric iron. In soybean, this gene is associated with cellular iron ion homeostasis, iron transport, and DNA protection, as well as glucose homeostasis, ureide breakdown, proline metabolism, cellular respiration, phloem loading, protein storage, and responses to water and flooding. It localises to the cytoplasm. GmFER3 is linked to several agronomically relevant traits, including iron concentration, chlorophyll content, net photosynthetic rate, seed protein content, plant height, drought tolerance, and salt tolerance. Related genes in other species connect the family to oxidative stress response, though this has not been established for GmFER3 itself.
