Fig. 6: Inhibitory effect of F. anhuiense against F. oxysporum and F. anhuiense population enhancement by tocopherol acetate in planta.
From: General variation in the Fusarium wilt rhizosphere microbiome
In planta experiments (n = 3 biologically independent samples per group; each sample consisted of a pooled collection from 30 tomato plants). Treatments: C (control), T (tocopherol acetate), K (F. anhuiense K5), TK (tocopherol acetate+F. anhuiense K5). Spores of F. oxysporum were inoculated in all treatments. A Colony count of F. oxysporum at 15 days. Compared with the control, the P values for the K and TK groups were 1.76 × 10−2 and 4.50 × 10−3, respectively (one‑way ANOVA followed by Dunnett’s post hoc test). B Colony counts of F. anhuiense K5 at 15 days. Compared with the control, the P value for the K group was 4.69 × 10−3 (Student’s two‑sided t test). C Disease index at 15 days. Compared with the control, the P values for the K, T and TK groups were 1.24 ×10−3, 1.30 × 10−3, and 1.60 × 10−4, respectively (one‑way ANOVA followed by Dunnett’s post‑hoc test). Data in A–C are presented as box plots showing the median (center line), the 25th and 75th percentiles (box limits), and the minimum and maximum values (whiskers). D Proposed model for Flavobacterium enrichment in the rhizosphere of infected plants. Pathogen infection enhances root secretion of tocopherol acetate, which promotes beneficial Flavobacterium growth. The recruited Flavobacterium may subsequently suppress F. oxysporum invasion through antimicrobial activity. Orange and blue arrows represent root‑exudate–pathogen and root‑exudate–probiotic interactions, respectively. Created in BioRender. Lv, Su. (2025) https://www.biorender.com/7cods4t.
