In fact, among the three populations, extremely significant differences were found for CYP4C67 [ F ( 2 , 27 ) = 21.056, P < 0.001], CYP4C68 [ F ( 2 , 27 ) = 14.979, P < 0.001], CYP4C70 [ F ( 2 , 27 ) = 28.084, P < 0.001], and CYP4DB1 [ F ( 2 , 27 ) = 19.673, P < 0.001].
The differences of mean relative abundances of four symbiotic bacteria among three populations were marginally significant; however, the mean relative abundance of 16 fungi among three populations was significantly different, and positive linear correlations were observed between the resistance level and two fungi ( Aspergillus niger and Aureobasidium pullulans ) and two genes ( CYP4C70 and CYP4DB1 ).
