Light Modulates Growth-Resistance-Quality Trade-Offs in Pseudostellaria Heterophylla via a Light-Induced Microbiota-Root-Shoot Axis.

Shading enhances growth and disease resistance in Pseudostellaria heterophylla by modulating a microbiota-root-shoot axis, with beneficial microbiota enriched under low light conditions.

• Why it matters: Understanding how light influences plant-microbiota interactions is crucial for optimizing medicinal herb cultivation and improving plant resilience under shaded environments.
• What they did: The study combined phenotypic, microbiome sequencing, transcriptomics, and co-culture experiments to analyze responses to graded shading, revealing microbiome shifts and gene regulation patterns.
• The result: Findings show shading promotes beneficial bacteria and metabolic changes that boost growth and disease resistance, providing a framework for sustainable understory cultivation strategies.
