An international team is using advanced tools to develop crops that give farmers more options for sustainably producing more food on less land.
An international team is using advanced tools to develop crops that give farmers more options for sustainably producing more food on less land. To do this, thousands of plant prototypes must be carefully analyzed to figure out which genetic tweaks work best. Today, in a special issue of the journal Remote Sensing of Environment, scientists have shown a new technology can more quickly scan an entire field of plants to capture improvements in their natural capacity to harvest energy from the sun.
“The method we developed allows us to measure improvements we have engineered in a plant’s photosynthesis machinery in about ten seconds, compared to the traditional method that takes up 30 minutes,” Katherine Meacham-Hensold, a postdoctoral researcher at the University of Illinois, who led this work for a research project called Realizing Increased Photosynthetic Efficiency (RIPE). “That’s a major advance because it allows our team to analyze an enormous amount of genetic material to efficiently pinpoint traits that could greatly improve crop performance.”

Now they can use a measurement technique that takes 10 seconds—rather than 30 minutes—to assess genetically modified crops. Credit: Beau Barber/University of Illinois
