FDX6 — Sorghum bicolor

Summary

SORBI_3009G154700 (symbol FDX6) on sorghum chromosome 9 encodes a ferredoxin family protein with 2Fe-2S cluster binding, ferrous iron binding, and electron transfer activity. It is associated with ferredoxin metabolism, the electron transport chain, sucrose anabolism and breakdown, and homeostasis. The gene product localises to the chloroplast and etioplast stroma. FDX6 is associated with forage yield, sugar content, and salt tolerance. Related genes in other species link the family to photosynthetic electron transfer and stress responses, though these associations are not yet established in sorghum.
