- Setaria viridis is a species of grass that is a member of the Panicoid family, which is the most economically important family of grass species, and includes maize, sorghum and sugarcane. Each of the above listed members of the Panicoid family undergoes C4 photosynthesis of carbon capture and fixation.
- They are also morphologically characterized as having Kranz anatomy, such that bundle-sheath (BS) and mesophyll (M) cells arranged in concentric circles around the vascular bundles of the leaves.
- C4 photosynthesis can be subdivided into three main subtypes, which are biochemically distinct. In the case of S. viridis, atmospheric CO2 is first fixed in the M cytoplasm by PEPC (phosphoenol-pyruvate carboxylase), and after chemical modifications it is transformed into a four-carbon compound (malate).
- The malate is then transported into BS chloroplasts where the decarboxylation step is performed mainly by the NADP-dependent malic enzyme (NADP-ME), leading to the release of CO2 close to the active site of the RuBisCO enzyme.
- In C4 plants, RuBisCO is confined to BS cells, and this partitioning of carbon assimilation and carbon fixation steps greatly reduces the losses caused by photorespiration. Such an arrangement enables these plants to more efficiently use water and nitrogen, especially in hot and dry environments.
