Extended Data Fig. 3: myo-Inositol restored B. megaterium YC4-R4 biofilm formation on the roots of rdd and ros1 (Related to Fig. 4).

Roots of Col-0, rdd and ros1 were shown in bright field images (a) and Scanning Electronic Microscopy (SEM) images (b). For samples with no visualized biofilm, less amplified images were used to show no visual findings. Red area or arrows indicate bacteria in the bright field images. Blue area indicates biofilm in the SEM images. In both cases, images show representative pictures from three independent experiments with similar results (n = 5 biological independent samples).
