Root colonization assay of tvhydii1 strains. Relative quantification of sm1 amplification in tomato roots colonized by T. virens 29.8, Δtvhydii1 T2.1, Δtvhydii1 T2.3, tvhydii1OE T2 and tvhydii1OE T5. 2^(−ΔΔCt), values represent the amplification level of sm1 gene relative to the amplification level of the expressed gene of the plant DNA, compared to the control condition (tomato DNA). T. virens 29.8 and S. lycopersicum DNA were used as amplification controls. Data were analyzed with a one-way ANOVA and a Bonferroni post hoc test; ** p < 0.01; *** p < 0.001. Values represent means of three replicates, bars indicate standard deviation
