摘要

The dominant bacteria enriched in the Fusarium wilt plants’ rhizosphere are of increasing interest, as they adapt well to the diseased rhizosphere. However, general information about these bacteria is still lacking. Here, we perform a meta-analysis of Fusarium wilt plants rhizosphere and comprehensive studies to obtain information about the robust variation in the rhizosphere microbiome of Fusarium wilt plants. We demonstrate that Fusarium infection reproducibly changes the rhizosphere bacterial community composition. The rhizosphere microbiomes of Fusarium wilt plants are characterized by the enrichment of Flavobacterium, gene cassettes involved in antioxidant functions related to sulfur metabolism and the root secreted tocopherol acetate. We further isolate antagonistic Flavobacterium anhuiense from the diseased tomato rhizosphere, and reveal that the growth of F. anhuiense and the expression of genes related to carbohydrate metabolism in this strain are significantly stimulated by tocopherol acetate. Furthermore, the inhibitory effect of F. anhuiense against F. oxysporum and F. anhuiense population enhancement by tocopherol acetate are confirmed in planta. The robust variation in the rhizosphere microbiome elucidates key principles governing the general assembly mechanism of the microbiome in the Fusarium wilt plants’ rhizosphere.
