phytobiome
A phytobiome encompasses the entire ecological system surrounding a plant, including the complex communities of bacteria, fungi, insects, animals, and other organisms that live in, on, and around it, along with the soil, air, and climate of its environment. Understanding phytobiomes is critical for plant science because plant health, growth, and resilience are shaped not just by genetics but by thousands of dynamic interactions with surrounding organisms. Research in this field is revealing how manipulating these microbial and ecological communities can improve crop productivity, disease resistance, and adaptation to environmental stress.

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.
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.
