Loss of PSAE redirects PGRL1 to photosystem I and enhances PGR5-dependent cyclic electron transfer in Arabidopsis
Gustaf E. Degen, Erin Park, Matthew P. Johnson
This study shows that loss of PSAE in Arabidopsis enhances PGR5-dependent cyclic electron transfer and redirects PGRL1 to PSI, while NDH supports CO2 fixation under disrupted PSI conditions.
