Rhizosphere microbial diversity analysis reveals enrichment of biocontrol taxa in healthy tobacco plants and yields novel antagonists against Phytophthora nicotianae
Introduction Tobacco black shank (TBS), caused by Phytophthora nicotianae, is a devastating disease. Current control relies heavily on chemical pesticides, which pose risks of resistance and environmental pollution. Biological control using rhizosphere microorganisms offers a sustainable alternative. However, the relat...
