Description
Qing Shu and co-authors test a bacterium that lives in plant tissue, as a biocontrol that might fight root rot in a plant used as medicine. Their 2026 study deals with Paris polyphylla variety yunnanensis. That plant is at risk from the fungus Fusarium oxysporum.
The bacterium is Sphingobium xenophagum strain J-1. It was drawn from healthy plants of the same species. An extract from its fermentation broth slowed the sprouting of fungal spores. The effect grew with the dose, and hit a high rate at the most strong dose tested. Under the microscope, hyphae looked swollen and split into parts. Their contents leaked out, and spaces formed in them. The extract seemed to break up fungal cell membranes. The team stresses that this is in vitro proof only. Tests in a greenhouse and in the field are still needed.
