Disequilibrium between chloroplast proton motive force and ATP levels in Arabidopsis.

Nature plants - 1 Sept 2026

Degen Gustaf E, Schwarzländer Markus, Johnson Matthew P

Abstract excerpt

Current dogma holds that CO2 fixation by photosynthesis requires additional ATP production via cyclic electron transfer, mediated by two distinct pathways involving the NADH dehydrogenase-like complex (NDH) and proton gradient regulation 5 protein (PGR5), to augment the ATP relative to NADPH produced by linear electron transfer. Here we use the MgATP2- fluorescent biosensor ATeam1.03-nD/nA and find that, while...
