NDH complex-mediated cyclic electron flow in bundle sheath cells enables C4 photosynthesis

This study shows that NDH complex-mediated cyclic electron flow in bundle sheath cells is essential for ATP production required for CO2 fixation in C4 photosynthesis.

Recording true oxygen reduction capacity during photosynthetic electron transfer in Arabidopsis thylakoids and intact leaves

The paper quantifies oxygen reduction and H2O2 accumulation in thylakoids and leaves, showing H2O2 accumulates at Photosystem I and may enhance mitochondrial respiration during stress.

Up-regulation of bundle sheath electron transport capacity under limiting light in C4 Setaria viridis

This study shows that under low light, bundle sheath cells in C4 Setaria viridis upregulate electron transport components and alter PSII composition, enhancing their capacity for linear electron flow.

A commonly used photosynthetic inhibitor fails to block electron flow to photosystem I in intact systems

The paper investigates the efficacy of DNP-INT as a photosynthetic inhibitor and finds it fails to block electron flow to photosystem I in intact systems.

Cytochrome cM downscales photosynthesis under photomixotrophy in Synechocystis sp. PCC 6803

The study shows that deletion of cytochrome cM in Synechocystis sp. PCC 6803 prevents photosynthesis reduction under photomixotrophy, maintaining higher growth rates.

Increased expression of mitochondrial dysfunction stimulon genes affects chloroplast redox status and photosynthetic electron transfer in Arabidopsis

This study shows that increased MDS gene expression in Arabidopsis affects chloroplast redox status and photosynthetic electron transfer, with hypoxia mitigating these effects in an MDS-overexpressor mutant.
