General Information

General Information Comment Organism
physiological function in the plastids of higher plants, ferredoxin-NADP+ oxidoreductase (FNR) mediates electron transfer between ferredoxin (Fd) and NADP+. In Arabidopsis, two leaf-type ferredoxin-NADP+ oxidoreductase (LFNR) isoforms function in photosynthetic electron flow in reduction of NADP+, while two root-type FNR (RFNR) isoforms catalyse reduction of ferredoxin in non-photosynthetic plastids. The function of RFNRs might lie in their spatial and temporal distribution in different plant tissues and cell types. Although the function of the RFNR isozymes 1 and 2 is partly redundant, the RFNR proteins are essential for plant development and survival. The strict regulation of RFNR gene expression and differential accumulation of the RFNR isoforms within the root suggests that RFNR1 and RFNR2 may have distinct physiological roles in the root metabolism Arabidopsis thaliana
