A new bioengineering approach for boosting photosynthesis in rice plants could increase grain yield by up to 27 percent, according to a new study. The approach, called GOC bypass, enriches plant cells with CO2 that would otherwise be lost through a metabolic process called photorespiration. The genetically engineered plants were greener and larger and showed increased photosynthetic efficiency and productivity under field conditions, with particular advantages in bright light.
