Disequilibrium between chloroplast proton motive force and ATP levels in Arabidopsis

Gustaf E. Degen, Markus Schwarzländer, Matthew P. Johnson

The paper shows that in Arabidopsis pgr5CAS mutant, proton motive force is reduced but MgATP2- levels remain unchanged, suggesting PGR5-CET is not needed for ATP augmentation.

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.

Tethering ferredoxin-NADP+ reductase to photosystem I promotes photosynthetic cyclic electron transfer

Tom Z. Emrich‐Mills, Matthew S. Proctor, Gustaf E. Degen, Philip J. Jackson, Katherine H. Richardson, Frederick R. Hawkings, Felix E. Buchert, Andrew Hitchcock, Christopher Neil Hunter, Luke C. M. Mackinder, Michael Hippler, Matthew P. Johnson

This study shows that tethering FNR to PSI in Chlamydomonas reinhardtii promotes CET over LET, reducing CO2 fixation.
