Cell-preferential PGRL1 paralogs provide distinct modes of photoprotection in C ₄ photosynthesis

Abstract The PGR5-PGRL1 pathway protects plants from photodamage by regulating electron flow to maintain Photosystem I in an oxidised state. Grasses possess two PGRL1 paralogs, but their functional roles have remained unknown.

In vivo chlorophyll fluorescence screening allows the isolation of a Chlamydomonas mutant defective for NDUFAF3, an assembly factor involved in mitochondrial complex I assembly

, 2017
peer reviewedThe qualitative screening method to select complex I mutants in the microalga Chlamydomonas, based on reduced growth under heterotrophic condition, is not suited for high throughput screening.

FOCUSING ON A NEW BIOHYDROGEN PRODUCTION STRATEGY USING CHLAMYDOMONAS REINHARDTII MUTANTS

, 2022
Microalgae have been drawn great attention due to their biohydrogen production potentials. In this study, we investigated biohydrogen production potentials of Chlamydomonas reinhardtii strains as D1 protein mutant strain D240-41, PGRL1 single mutant ...

Structure-Function of the Cytochrome B6f Complex in Oxygenic Photosynthesis: Molecular Control of Electron Transport and Thermodynamic Analysis of the Interaction of a Proposed Protein Ligand

, 2020
In the first study presented here, the 2.5 Å crystal structure1 of the cytochrome b6f complex obtained from the cyanobacterium Nostoc sp. PCC 7120 (pdb 4OGQ) was used as a guide for modification by site-directed mutagenesis in the cyanobacterium ...

Loss of PSAE redirects PGRL1 to photosystem I and enhances PGR5-dependent cyclic electron transfer in Arabidopsis

Abstract Electrons energised by light energy at photosystem I (PSI) primarily enter the linear photosynthetic electron transfer (LET) or cyclic electron transfer (CET) pathway. The balance between LET and CET activity is a crucial factor in the regulation of photosynthesis, since CET increases the stoichiometry of ...

Redox and ATP control of photosynthetic cyclic electron flow in Chlamydomonas reinhardtii: (II) involvement of the PGR5-PGRL1 pathway under anaerobic conditions.

Biochimica et biophysica acta, 2014
In oxygenic photosynthesis, cyclic electron flow around photosystem I denotes the recycling of electrons from stromal electron carriers (reduced nicotinamide adenine dinucleotide phosphate, NADPH, ferredoxin) towards the plastoquinone pool. Whether or not cyclic electron flow operates similarly in Chlamydomonas and plants has been a matter of debate ...

Régulation du transfert d' électrons photosynthétiques et de la photo-production d' hydrogène chez Chlamydomonas reinhardtii

, 2015
Deux voies de transfert cyclique d’électrons ont été décrites chez l’algue verte C.reinhardtii, une implique (PGRL1 et PGR5), l’autre une NADP(H)-plastoquinone oxidoréductase (NDA2). Le TCE participerait à la génération d’ATP et donc à l’équilibration de

Adaptation of mechanisms for regulation of photosynthetic electron transport upon land colonization [PDF]

, 2018
In eukaryotic organisms, oxygenic photosynthesis is catalyzed by 4 multiprotein complexes present on the thylakoid membranes inside the chloroplasts: Photosystem (PS) II, Cytochrome b6f (Cyt b6f), PSI and chloroplast ATP synthase (ATPase).

Regulation of photosynthesis under dynamic light conditions in Chlamydomonas reinhardtii : Impact on hydrogen production [PDF]

, 2017
The development of renewable biofuels to ensure sustainable energy supply is one of the biggest global challenges of modern society. Hydrogen has great potential to become the fuel of the future, since it provides energy without CO2 emission.
