Shapeshifting plant roots rely on a balance of anatomy, metabolism, and microbes to maximize survival
Researchers at the University of Nottingham have discovered that plant root anatomy plays a critical role in how roots recruit and interact with soil microbes. This structural plasticity allows plants to adapt to nutrient-poor environments by remodeling their root systems in response to microbial colonization.
Why it matters
Understanding these plant-microbe interactions could lead to more resilient agricultural practices and improved crop yields in challenging soil conditions.

The findings could pave the way for developing new ways to improve beneficial plant-microbe interactions in agriculture.
Roots naturally vary in the complexity of their cross-sectional anatomy—from the thick, woody root of a mangrove to the fine, hairlike strands of a scallion or duckweed.
