Randy Moore and Clanton C. Black, Jr. Nitrogen assimilation in crabgrass Digitaria sanguinalis (L.) Scop., was studied by comparing leaf extracts with isolated mesophyll cell and bundle sheath strand ...

The photo-oxidation of cytochrome f (cytochrome $\text{c}_{554}$) in bundle sheath cells isolated from leaves of maize (Zea mays var. DS 606A) has been compared with that in intact maize leaf and in ...

C4 photosynthesis represents a striking example of convergent evolution, where multiple plant lineages have independently modified an ancestral C3 pathway to enhance carbon fixation efficiency. This ...

Cross sections of C3 rice (left) and C4 sorghum (right) shoots. Both grain crops evolved from a common ancestor, but sorghum evolved to photosynthesize more efficiently. LA JOLLA (November 20, ...
