FER1 — Phaseolus vulgaris

Summary

PHAVU_008G221200, designated PvFER1, encodes a ferritin protein with ferroxidase activity and the ability to bind ferrous and ferric iron, and is associated with cellular iron ion homeostasis. In French bean (Phaseolus vulgaris) on chromosome 8, this gene is associated with iron transport, nitrogen fixation, nodulation, nitric oxide storage, and response to oxidative stress. It is also linked to photosynthetic rate. The protein localises to the cytoplasm. Studies of related genes in other species connect the family to seed protein content, net photosynthetic rate, and salt tolerance, though these associations are not yet established for PvFER1 itself.
