Journal ArticleDOI
Flavodiiron proteins act as safety valve for electrons in Physcomitrella patens.
Caterina Gerotto,Alessandro Alboresi,Andrea Meneghesso,Martina Jokel,Marjaana Suorsa,Eva-Mari Aro,Tomas Morosinotto +6 more
TL;DR: In P. patens, Flavodiiron (FLV) proteins are acting as an electron sink to avoid photosynthetic electron transport chain over-reduction after any increase in illumination and are fundamental for protection under fluctuating light conditions.
Journal ArticleDOI
Combined Increases in Mitochondrial Cooperation and Oxygen Photoreduction Compensate for Deficiency in Cyclic Electron Flow in Chlamydomonas reinhardtii
Kieu-Van Dang,Kieu-Van Dang,Kieu-Van Dang,Julie Plet,Julie Plet,Julie Plet,Dimitri Tolleter,Dimitri Tolleter,Dimitri Tolleter,Martina Jokel,Stéphan Cuiné,Stéphan Cuiné,Stéphan Cuiné,Patrick Carrier,Patrick Carrier,Patrick Carrier,Pascaline Auroy,Pascaline Auroy,Pascaline Auroy,Pierre Richaud,Pierre Richaud,Pierre Richaud,Xenie Johnson,Xenie Johnson,Xenie Johnson,Jean Alric,Jean Alric,Jean Alric,Yagut Allahverdiyeva,Gilles Peltier,Gilles Peltier,Gilles Peltier +31 more
TL;DR: It is concluded that a combination of mitochondrial cooperation and oxygen photoreduction downstream of PSI (Mehler reactions) supplies extra ATP for photosynthesis in the pgrl1 mutant, resulting in normal biomass productivity under steady state conditions.
Journal ArticleDOI
Flavodiiron Protein Flv2/Flv4-Related Photoprotective Mechanism Dissipates Excitation Pressure of PSII in Cooperation with Phycobilisomes in Cyanobacteria
Luca Bersanini,Natalia Battchikova,Martina Jokel,Ateeq Ur Rehman,Imre Vass,Yagut Allahverdiyeva,Eva-Mari Aro +6 more
TL;DR: Results of biophysical measurements indicate that the flv4-2 operon functions in an alternative electron transfer pathway from PSII, and thus alleviates PSII excitation pressure by channeling up to 30% of PSII-originated electrons.
Journal ArticleDOI
Hunting the main player enabling Chlamydomonas reinhardtii growth under fluctuating light.
TL;DR: Different roles, yet a close relationship, are suggested between the function of PGR5, PGRL1 and FDP proteins in photoprotection, with flv mutant lines unable to survive even mild FL conditions.
Journal ArticleDOI
A new approach for sustained and efficient H2 photoproduction by Chlamydomonas reinhardtii
TL;DR: Sustained H2 photoproduction is demonstrated in green algae under a train of strong white light pulses interrupted by longer dark phases, which relies on the presence of the [FeFe]-hydrogenase in algal chloroplasts.
