摘要

Tomato bacterial wilt caused by the soil-borne pathogen Ralstonia solanacearum presents a critical challenge to global tomato production, causing substantial yield losses and quality deterioration. This study demonstrates that Bacillus velezensis ZN-S10 effectively controls tomato bacterial wilt through a series of pot experiments and field trials. Metagenomic analysis revealed that ZN-S10 significantly alters the diversity, richness, and network structure of bacterial communities in the tomato rhizosphere, notably enriching beneficial microbes such as Sphingomonas. During ZN-S10 inoculation and R. solanacearum infection, the expression of enzymes involved in pyruvate and acetate synthesis increased. Pot experiments confirmed that introducing Sphingomonas, along with pyruvate and acetate, enhanced tomato resistance to R. solanacearum, as evidenced by increased levels of these organic acids. These findings establish a novel tripartite mechanism where ZN-S10 simultaneously primes plant immunity, enlists beneficial microbiota, and activates critical metabolic pathways, proposing an innovative strategy for sustainable disease management in solanaceous crops.
