Spatial resolution of an integrated C4+CAM photosynthetic metabolism (Sci. Advances)
C4 and CAM are both photosynthetic strategies that concentrate CO2 upstream of RuBisCO, somewhat uncoupling photosynthetic carbon fixation from transpirational water loss. Both strategies use the enzyme PEP-carboxylase to produce an organic acid, which can then be decarboxylated to provide CO2 to RuBisCO. In the C4 system, PEP-carboxylase operates in mesophyll cells and RuBisCO in […]
