Additional file 4: Fig. S4. Phylogeny and community structure of culturable denitrifying bacteria in response to AMF hyphae in the in vitro experiment. A, Phylogenetic tree of culturable denitrifying bacteria from patches of faba bean residue. This was constructed by the neighbor-joining method based on 16S rRNA gene sequences. Names of strains obtained from this study are shown in bold. B, Relative abundances of major culturable denitrifying bacterial communities in the absence or presence of AMF (n = 5). Asterisks, significant differences between the −AMF and +AMF treatments according to the Wilcoxon rank sum test (*, P < 0.05; **, P < 0.01; ***, P < 0.001). C, Nonmetric multidimensional scaling (NMDS) pattern of culturable denitrifying bacterial communities between −AMF and +AMF treatments based on Bray–Curtis dissimilarity. Ellipses in the plots indicate 95% confidence intervals for microbial communities under the −AMF and +AMF treatments (n = 5).
