Metabolome-driven rhizosphere microbiome assembly determining the health of medicinal herb (Angelica sinensis) against root rot.
Researchers discovered that healthy dong quai plants recruit beneficial soil bacteria (Streptomyces) by releasing specific lipid compounds from their roots, which helps suppress the fungal disease Fusarium root rot. Applying these lipids together with the beneficial bacteria as a 'synbiotic' treatment successfully protected plants from disease.
