U.S. researchers have tweaked plant machinery to create crops that can respond to rising levels of atmospheric CO2 , photosynthesize more.

In field experiments, they produced sugarcane and sorghum crops that generated between 15 and 81% more biomass.

The study expands a growing field of work to hack photosynthesis in the attempt to make more productive crops.

“In the bigger picture, I would like to get a better understanding of how plants with increased Rubisco content respond to abiotic stress conditions such as heat, cold and drought in order to further future proof’ these crops” Salesse-Smith et. al . “Adapting C4 photosynthesis to atmospheric change and increasing productivity by elevating Rubisco .
