AP1 — Brassica juncea

Summary

BJUB03G55540S (symbol AP1, preferred name BjFD1) on Indian mustard chromosome B03 encodes a ferredoxin protein containing 2Fe-2S cluster-binding and electron transfer activity domains. The gene product is associated with ferredoxin metabolism, the electron transport chain, and response to light stimulus, and localises to the chloroplast stroma. BjFD1 has been linked to meristem identity, plant height, linear electron flow, and heat stress tolerance. Related genes in other species connect the ferredoxin family to lignin content, high temperature stress response, and photochemical quenching.
