Devosia promotes plant growth, mycorrhization, and N accumulation. Boxplots show A shoot dry weight, B root dry weight, C percentage of each root system colonized by AM fungi, D shoot N accumulation, and E shoot P accumulation of 8-week-old Prunella plants cultivated in autoclaved soil (Control) or inoculated with Devosia sp. ZB163 (Devosia), R. irregularis (AM), or both symbionts. In the 6th, 7th and 8th week, plants were watered with modified Hoagland solution without N and P. Significant differences are indicated with letters (ANOVA and Tukey’s Honest HSD test). F Photographs of the Prunella plants immediately before harvest. Red circles indicate plants that were later found to be colonized by AM fungi
