Since the components, structure, and regulatory mechanisms of the light reactions of photosynthesis are well understood, concepts for enhancing the process have been suggested and partially tested. These approaches vary in complexity, from targeting single components to comprehensive redesign of the whole process on the scales from single cells or tissues to whole canopies.

Integrated, systems-wide approaches are required to achieve breakthroughs that effectively increase crop yields through photosynthesis engineering.
The reviewed efforts to enhance the light reactions of photosynthesis are still in an early exploratory phase and/or have not resulted in the desired outcome.
The review surveys engineering strategies to enhance the light reactions of photosynthesis, ranging from single-component interventions to comprehensive redesign across scales from cells and tissues to whole canopies.
A major reason these engineering efforts have not yet achieved the desired outcome is that photosynthesis is embedded in large networks of closely interacting cellular and metabolic processes that vary among species and cultivars.
