Prospects for improving CO₂ fixation in C₃-crops through understanding C₄-Rubisco biogenesis and catalytic diversity

Sharwood, Robert E; Ghannoum, Oula; Whitney, Spencer M

Description

By operating a CO₂ concentrating mechanism, C₄-photosynthesis offers highly successful solutions to remedy the inefficiency of the CO₂-fixing enzyme Rubisco. C₄-plant Rubisco has characteristically evolved faster carboxylation rates with low CO₂ affinity. Owing to high CO₂ concentrations in bundle sheath chloroplasts, faster Rubisco enhances resource use efficiency in C₄ plants by reducing the energy and carbon costs associated with photorespiration and lowering the nitrogen investment in...[Show more]
