That process, called carbon fixation, resulted in the assembly of ... These rice plants combat photorespiration via C4 photosynthesis. Credit: Utsman Media/Unsplash Some plants, like rice, wheat ...

C3 and C4 plants respond differently to changing carbon dioxide concentrations thanks to differences in the molecular pathways they use to capture the gas from the atmosphere. While C3 plants use an ...

Four autotrophic carbon-fixation pathways were already known and Berg et al. now report a fifth pathway that is used by archaea from diverse habitats. The best-known autotrophic pathway is the ...
