Differential abundance analysis performed at genus level by ANCOM-BC of differently treated apple saplings at the last sampling timepoint (TP3). Results are shown for the L- and T-associated bacterial communities (upper and lower panel, respectively). Plants were inoculated with P. leucotricha and then left untreated (IU) or treated with a synthetic fungicide (IT) or remained uninoculated and treated with water as control (NC). The heatmap shows the coefficients obtained from the ANCOM-BC log-linear model divided by their standard error (called W-value). The colour code indicates differential abundances between two treatments with red indicating enrichment in the last value of the column name. A “*” is shown if ANCOM-BC showed significant differences based on adjusted p-values in this comparison. In addition, the mean relative abundances of the taxa are displayed and only taxa with a mean relative abundance of > 0.1% are shown
