This helps ensure that they don’t overcommit resources to harvesting sunlight when other factors, like water and nutrients, might limit their growth.īut it’s not necessary for plants to do that, says David Savage, a plant biologist at the University of California, Berkeley and member of the IGI research team. For instance, when it’s very sunny outside, plants will often turn off key proteins involved in collecting photons of light. But in recent decades, plant biologists have discovered that the process is surprisingly inefficient.

It took hundreds of millions of years for the biochemical machinery behind photosynthesis to evolve. The plant then uses the organic carbon to grow new leaves, shoots, and roots.

There, energy from sunlight is used to strip electrons from water molecules and add them to carbon dioxide, transforming it into glucose, a simple sugar. Plants’ ability to sequester carbon naturally begins inside tiny cellular compartments called chloroplasts. CRISPR can be used to make positive effects on climate, and so we’re going for it.” Optimizing plants “Climate change is a serious, serious problem,” says Brad Ringeisen, the executive director of the IGI and lead principal investigator on the project. But the researchers believe their ambitious project meets the urgency of the climate crisis. Additional social, policy, and ethical considerations will determine whether those crops are widely adopted by farmers. It’s a tremendously ambitious goal, and the team is likely to face numerous challenges in the lab before its CO2-scrubbing plants can be put in the ground. Eventually, the researchers hope to create gene-edited rice and sorghum seeds that could-if planted around the globe-pull more than a billion extra tons of carbon out of the air annually. With an $11-million gift from the Chan Zuckerberg Initiative, a team of plant geneticists, soil scientists, and microbial ecologists embarked on a three-year effort using CRISPR to create new crop varieties that photosynthesize more efficiently and funnel more carbon into the soil. Last month, the Innovative Genomics Institute (IGI), a San Francisco Bay area research consortium founded by CRISPR pioneer Jennifer Doudna, began to explore the idea in earnest.

About half of that carbon winds up in roots and eventually the soil, where it can stay for hundreds to thousands of years.īut what if we could create plants and soils that are even better at capturing carbon? With CRISPR genome editing-a revolutionary new molecular biology toolset that allows scientists to make rapid and precise edits to the DNA code that underpins all life-that might be possible. Plants are among the best tools we have to do this, since these living solar collectors already capture billions of tons of carbon dioxide each year from the atmosphere through photosynthesis. Because it’s virtually impossible for humanity to do that as fast as is now required, we will also need to pull carbon out of the air and secure it. To prevent dangerous levels of global warming, scientists say it won’t be enough to just stop burning fossil fuels that release carbon into the air.
