Should nations prioritize developing genetically modified crops to help combat climate change?
Salk Institute researchers have initiated field trials for genetically modified soybeans designed with roots that penetrate deeper into soil. This research, supported by an $18 million grant from the Bezos Earth Fund, aims to store more carbon underground while potentially improving crop resilience.
Why it matters
The development of crops capable of deeper root growth addresses both climate change mitigation and agricultural food security risks. By increasing the depth of root systems, these plants may store significantly more carbon while providing greater protection against drought conditions.
Researchers identified 347 genes linked to root growth and carbon storage to engineer the deeper root structure. Each hectare of these modified crops is estimated to sequester one additional metric ton of carbon dioxide annually.
The players
Salk Institute
A non-profit research organization focused on biological sciences, including plant biology and molecular genetics.
Bezos Earth Fund
A philanthropic fund established to support research and initiatives addressing climate change and environmental issues.
University of Illinois Urbana-Champaign
A public research university utilizing advanced soil sensors and imaging for crop science field trials.
The details
Scientists used gene-editing techniques to target specific pathways responsible for root expansion, allowing plants to reach deeper soil layers. At the University of Illinois Urbana-Champaign and other sites in Illinois, Missouri, Kansas, and Iowa, researchers use underground cameras and specialized sensing equipment to monitor carbon sequestration rates and root penetration depth in real time.
Timeline
2020 to 2026: Scientists developed a genomic encyclopedia of row crops.
Fall 2026: Researchers expect initial results from field trials.
2040: Target year for potential annual removal of one gigaton of carbon if crops are adopted.
The Tech Race
This project builds directly on the Salk Institute's Harnessing Plants Initiative, which seeks to transform agricultural crops into effective carbon-capture tools. It extends ongoing efforts to optimize plant genomics for environmental stability rather than just caloric yield.
These crops are currently in the field-testing phase and are not yet available for commercial agricultural use. Future adoption will depend on performance data confirming that deeper root structures maintain consistent crop yields while providing climate mitigation benefits.
The takeaway
The trajectory of this research hinges on proving that carbon-sequestering genes do not negatively impact the total yield of soybean harvests. Interested observers should monitor the initial field trial results expected in fall 2026 to see if the laboratory performance is replicated in diverse soil conditions.
What happens next
Researchers expect to publish the initial results from the multi-state field trials in the fall of 2026.
