FER3 — Cicer arietinum

Summary

FER3 on chickpea chromosome 3 encodes a ferritin protein with ferroxidase activity and the ability to bind ferric and ferrous iron. This gene is associated with cellular and multicellular organismal iron ion homeostasis, iron transport, response to oxidative stress, and response to abscisic acid. It is linked to leaf and flower development, electron transport chain function, glucose homeostasis, DNA protection, and ureide breakdown. Associations with agronomic traits include relative chlorophyll content, photosynthetic rate, abscisic acid content, root morphology, and salt tolerance. The encoded protein localises to the cytoplasm, chloroplast envelope and stroma, mitochondria, Golgi complex, and cytosol. Studies of related genes in other species connect the family to iron storage, lateral root emergence, wounding response, and photoinhibition response.
