Cyclic and pseudo-cyclic electron pathways play antagonistic roles during nitrogen deficiency in Chlamydomonas reinhardtii

This study investigates the roles of cyclic and pseudo-cyclic electron pathways in Chlamydomonas reinhardtii under nitrogen deficiency, showing they have antagonistic effects on photosynthesis and carbon storage.

The chloroplast ATP synthase redox domain in Chlamydomonas reinhardtii attenuates activity regulation as requirement for heterotrophic metabolism in darkness.

This paper shows that Chlamydomonas reinhardtii uses a hairpin structure in the chloroplast ATP synthase {gamma}-subunit to disconnect redox regulation from disulfide formation, enabling metabolic coupling with mitochondria under heterotrophic conditions.

Cytochrome b6f complex inhibition by antimycin-A requires Stt7 kinase activation but not PGR5.

The paper shows that antimycin-A inhibits the cytochrome b6f complex in a PGR5-independent manner during cyclic electron flow, requiring Stt7 kinase activation.

ECS-based investigation of chloroplast ATP synthase regulation

This paper investigates chloroplast ATP synthase regulation in Arabidopsis using in vivo absorption spectroscopy, showing the {gamma}-subunit exists mostly oxidized in dark-adapted leaves and its redox state affects ATP synthesis efficiency.

PGR5 is required for efficient Q cycle in the cytochrome b6f complex during cyclic electron flow

This study re-evaluates the role of PGR5 in the cytochrome b6f complex of Chlamydomonas reinhardtii, showing it enables efficient Q cycle during cyclic electron flow by regulating redox activity modes.
