Characterization of a Unique Pair of Ferredoxin and Ferredoxin NADP⁺ Reductase Isoforms That Operates in Non-Photosynthetic Glandular Trichomes.

ABSTRACT: Our recent investigations indicated that isoforms of ferredoxin (Fd) and ferredoxin NADP⁺ reductase (FNR) play essential roles for the reductive steps of the 2C-methyl-D-erythritol 4-phosphate (MEP) pathway of terpenoid biosynthesis in peppermint glandular trichomes (GTs). Based on an analysis of several transcriptome data sets, we demonstrated the presence of transcripts for a leaf-type FNR (L-FNR), a leaf-type Fd (Fd I), a root-type FNR (R-FNR), and two root-type Fds (Fd II and Fd III) in several members of the mint family (Lamiaceae). The present study reports on the biochemical characterization of all Fd and FNR isoforms of peppermint (Mentha × piperita L.). The redox potentials of Fd and FNR isoforms were determined us
