Genera followed by an asterisk indicate a significant increase or decrease in the relative abundance in the infected samples as compared to the non-infection samples for the non-biochar treatment. As a comparison, the values of the biochar treated samples are included in the table in gray, in which no significant differences were observed. NI = non-infected, I = infected, BC = biochar addition.
