Abstract excerpt

In Arabidopsis thaliana, the main route of cyclic electron transport around PSI is sensitive to antimycin A, but the site of inhibition has not been clarified. We discovered that ferredoxin-dependent plastoquinone reduction in ruptured chloroplasts was less sensitive to antimycin A in Arabidopsis that overaccumulated PGR5 (PROTON GRADIENT REGULATION 5) originating from Pinus taeda (PtPGR5) than that in the wild...
