Systems analysis of long-term heat stress responses in the C4 grass Setaria viridis

This study examines the effects of long-term heat stress on Setaria viridis, revealing changes in metabolism, hormone levels, and gene expression, with a systems model of plant response.

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.

Faster responses of photosynthesis to light transitions increase biomass and grain yield in transgenic Sorghum bicolor overexpressing Rieske FeS

This study shows that overexpressing Rieske FeS in Sorghum bicolor improves photosynthetic responses to light changes, leading to higher biomass and grain yield.

Rieske FeS overexpression in tobacco provides increased abundance and activity of Cytochrome b6f

Overexpressing Rieske FeS in tobacco increases Cytochrome b6f abundance and activity, leading to transient improvements in photosynthetic electron transport.

Increased sedoheptulose-1,7-bisphosphatase content in the C4 species Setaria viridis does not affect photosynthesis

This study overexpresses SBPase in C4 plant Setaria viridis but finds no improvement in photosynthesis rates or CO2 assimilation.

Expression of a CO2-permeable aquaporin enhances mesophyll conductance in the C4 species Setaria viridis

The paper shows that expressing a CO2-permeable aquaporin in mesophyll cells of Setaria viridis increases CO2 diffusion conductance and enhances C4 photosynthesis.

Updating the steady state model of C4 photosynthesis

The paper updates a C4 photosynthesis model to include temperature dependencies and equations for calculating electron transport rates from CO2 assimilation measurements.

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.

The maize Aliphatic Suberin Feruloyl Transferase genes affect leaf water movement but are dispensable for bundle sheath CO2 concentration

This study shows that maize ZmAsft genes are not essential for CO2 concentration in bundle sheath cells but affect leaf water movement and cell wall properties.

Overexpression of the Rieske FeS protein of the Cytochrome b6f complex increases C4 photosynthesis

This study shows that overexpressing the Rieske FeS protein in C4 plants increases CO2 assimilation rates by enhancing electron transport efficiency.
