The N-use efficiency for photosynthesis was higher in a C₄ plant, maize, than in a C₃ plant, rice, including rbcS antisense rice with optimal ribulose-1,5-bisphosphate carboxylase (Rubisco) content for CO₂-saturated photosynthesis, even when photosynthesis was measured under saturating CO₂ conditions. The N cost for the C₄ cycle enzymes in maize was not large, and the lower amount of Rubisco allowed a greater N investment in the thylakoid components. This greater content of the thylakoid components as well as the CO₂ concentrating mechanism may support higher N-use efficiency for photosynthesis in maize.
