Gene editing improved photosynthesis in soybeans, leading to a 33% increase in yield—just the latest example of the need to accelerate biotechnology like gene editing crops to save our food supply in the face of climate change.
The key finding: Gene editing can increase the efficiency of photosynthesis in soybeans, leading to greater crop yield, finds research released yesterday from the University of Illinois at Urbana-Champaign.
The details: “Crop leaves in full sunlight dissipate damaging excess absorbed light energy as heat. This protective dissipation continues after the leaf transitions to shade, reducing crop photosynthesis,” explain the researchers. However, by bioengineering the change in soybeans, the resulting higher “photosynthetic efficiency” led to a 33% increase in seed yield, without changes to “seed protein or oil content.”
The big picture: The research provides “a glimmer of potential that such methods could someday put more food on tables as climate change and other threats make it harder for vulnerable populations across the globe to feed their families,” explains The New York Times.
The next steps: The researchers said they only studied soy plants “grown in a single location during two crop seasons,” per The New York Times, so trials in different environments and weather conditions—and on different types of crops—are needed.
The bigger challenge: consumer acceptance.As we’ve reported, consumer acceptance of gene-edited foods is low, but when they’re educated about the science and the benefits, they’re more likely to try them. The problem? Only 37% of people in a recent survey had ever heard of gene-edited foods.
