Abundance of Devosia sp. ZB163 significantly correlates with plant weight, mycorrhization, and N and P accumulation. A Boxplot of the absolute abundance of Devosia DNA on roots of plants in sterilized soil inoculated with a mock solution (Control), Devosia sp. ZB163 (Devosia), R. irregularis (AM), or both symbionts. Letters indicate significant differences as determined by ANOVA with Tukey’s HSD test. B–E Scatter plots of the correlation between the absolute abundance of Devosia DNA and B total plant N accumulation, C shoot dry weight, D root dry weight, E hyphal colonization, and F total plant P accumulation. Correlations and probabilities thereof are determined using linear regression
