Additional file 5: Fig. S5. Response of Pseudomonas fluorescens to AMF hyphal exudates and major compounds in the in vitro experiment. A, AMF hyphae with attached P. fluorescens stained with 4′,6-diamidino-2-phenylindole (DAPI); scale bar, 10 μm. B, Bacterial optical densities (OD600) of P. fluorescens in response to AMF hyphal exudates and major compounds (n = 3). C, Expression of the nirS gene and nosZ/nirS ratio of P. fluorescens in response to hyphal exudates and major compounds (n = 3). Different lowercase letters indicate significant differences among treatments by the least significant difference (LSD) test at the 5% level. D, Dynamic N2O concentrations in the headspace of serum bottles emitted from three strains of P. fluorescens in response to glucose, citrate, and hyphal exudates (n = 3). Asterisks, significant differences between hyphal exudate or citrate treatment and glucose treatment at 3 h within each strain according to two-tailed unpaired t-test (*, P < 0.05; ***, P < 0.001) .
