The specter of climate change looms large, demanding bold solutions. While reducing emissions remains paramount, removing existing carbon dioxide from the atmosphere is also crucial. Scientists estimate that in order to limit global warming to 1.5 degrees Celsius, we must not only curb future emissions but also actively remove billions of tons of carbon dioxide already present in the air.
Current methods of carbon capture are often expensive and energy-intensive. Here’s where nature steps in, offering a more elegant and sustainable solution: plants. Plants naturally absorb carbon dioxide through photosynthesis, converting it into organic matter and storing carbon in the process. Forests, for example, act as massive carbon sinks, playing a vital role in regulating atmospheric carbon dioxide levels. Salk Institute’s Harnessing Plants Initiative leverages this natural process but aims to take it a step further. By optimizing plant growth and root systems, scientists hope to create a new generation of plants that are even more adept at capturing and storing carbon dioxide, contributing significantly to the fight against climate change. In this ambitious botanical crusade, an unlikely but powerful tool comes into play: artificial intelligence (AI).

Nature itself offers a potent weapon in this fight – plants’ innate ability to store carbon dioxide. Salk scientists aim to optimize this natural process by focusing on the hidden world beneath the surface – the root system. Their secret weapon? A user-friendly AI software called SLEAP, developed by Salk Fellow Talmo Pereira. Originally designed for tracking animal movement in the lab, SLEAP has undergone a fascinating metamorphosis, adapted for plant research in collaboration with Professor Wolfgang Busch. Their groundbreaking research, published in Plant Phenomics, details a novel protocol for using SLEAP to analyze plant root phenotypes. These phenotypes encompass root depth, width, mass, and other physical characteristics. Traditionally, measuring these traits involved laborious manual methods. SLEAP, however, revolutionizes this process, enabling the creation of the most extensive root phenotype catalog to date. This newfound ability to analyze root systems with unprecedented detail and efficiency paves the way for the development of these next-generation carbon-capturing plants.

But SLEAP’s power goes beyond mere measurement. It delves deeper, facilitating the identification of genes associated with specific root traits. This allows scientists to pinpoint the genes most beneficial for designing plants with superior carbon capture capabilities. “This collaboration exemplifies the strength of Salk science,” says Pereira, highlighting the synergy between disciplines. Prior to SLEAP’s arrival, analyzing plant physical characteristics was a painstaking process. Researchers meticulously flagged relevant sections within images, a time-consuming step necessary before applying older AI models. SLEAP bypasses this tedious process altogether.
Its unique combination of computer vision and deep learning allows it to extract plant features directly from images, streamlining analysis and accelerating research. This newfound ability to link physical characteristics with underlying genes represents a significant leap forward. By understanding the genetic basis of desirable root traits, scientists can now target these genes to create plants specifically designed for maximized carbon capture. This marks a crucial step in the development of a powerful biological weapon against climate change.
SLEAP: Streamlining the Process
SLEAP’s innovation lies in its unique marriage of computer vision and deep learning. This powerful combination allows researchers to bypass the tedious pixel-by-pixel analysis, extracting plant features directly from images.
“We developed a robust protocol applicable to various plant types,” explains Elizabeth Berrigan, the study’s lead author. “SLEAP-roots, a downloadable open-source toolkit, streamlines analysis while prioritizing ease of use.”
SLEAP-roots facilitates processing key root system traits like depth, mass, and growth angles. Testing across a diverse range of plants, including soybeans, rice, and canola, revealed significant improvements. The SLEAP-based methods were 1.5 times faster for annotation, 10 times faster for AI model training, and 10 times faster for predicting plant structure from new data – all while maintaining accuracy.
Bridging the Gap: Phenotypes Meet Genotypes
These detailed phenotypic data – the comprehensive information about plant characteristics – are then combined with large-scale genome sequencing efforts. This powerful combination helps identify the genes responsible for desirable traits like deep root systems, crucial for long-term carbon storage in plants.
Connecting phenotypes and genotypes is a critical step in the creation of efficient carbon-capturing plants. “SLEAP has enabled us to develop the most extensive root phenotype catalog, accelerating our research on climate-fighting plants,” says Professor Busch.
Open Access and Global Impact
Accessibility and reproducibility were central tenets in SLEAP’s design. The free availability of both SLEAP and SLEAP-roots opens doors for global utilization. Discussions with NASA scientists highlight the potential for studying plants not only on Earth but also in space environments.
Back at Salk, the team’s journey continues. They are already tackling the challenge of analyzing 3D data with SLEAP. Refining, expanding, and sharing SLEAP and SLEAP-roots will be an ongoing process for years to come. However, its contribution to the Harnessing Plants Initiative demonstrates the transformative power of AI. By empowering plants to become active participants in the fight against climate change, SLEAP represents a root revolution with the potential to reshape our planet’s future.
