non-photochemical quenching redesign
Also known as: NPQ
Taxonomy: Mechanism Branch / Architecture. Workflows sit above the mechanism and technique branches rather than replacing them.
Summary
Secondly, strategies intended to optimize the acclimation of photosynthesis to changes in the environment are presented, including redesigning mechanisms to dissipate excess excitation energy (e.g., non-photochemical quenching)...

The abstract does not claim that NPQ redesign alone reliably increases crop yield. The review instead stresses that isolated interventions often fall short because photosynthesis is embedded in larger interacting networks.; the review states that these endeavors are still in an early exploratory phase and/or have not resulted in the desired outcome

Ranked Claims
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.
Acclimation-focused strategies discussed in the review include redesigning non-photochemical quenching to dissipate excess excitation energy and using flavodiiron proteins to dissipate excess reduction power.
Strategies discussed for enhancing light utilization per leaf include decreasing pigmentation, increasing photosynthetic protein levels, prolonging photosynthetic machinery lifespan, reconfiguring photosynthetic machinery, and incorporating nanomaterials.
