Soil Health
The hidden chemistry your garden plants pump into the soil every day shapes which beneficial bacteria and fungi thrive around their roots — and this new tool finally lets scientists decode those conversations at scale.
Plants constantly release chemicals from their roots into the soil, and these chemicals act like invitations for certain microbes while repelling others. Until now, scientists struggled to study this in the lab because growing microbes away from living plants meant missing those crucial chemical signals. This new system keeps the plant alive and secreting while microbes are cultured alongside it, making the experiment far closer to what actually happens in your garden.
Key Findings
The system captures diffusible metabolites from living plant roots in real time, enabling microbe culturing under plant-relevant chemical conditions rather than synthetic media alone.
LEAP-CS is designed as a high-throughput platform, meaning many microbe-plant combinations can be tested simultaneously — dramatically scaling discovery capacity compared to traditional one-at-a-time culturing.
The approach bridges culturomics (growing and cataloging microbes in bulk) with phytobiome research, potentially uncovering previously unculturable microbes that only grow in response to specific plant signals.

Researchers developed LEAP-CS, a new high-throughput lab system that cultures soil microbes in the presence of real, living plant root secretions — allowing scientists to study which microbes plants actually attract and communicate with under realistic conditions.
