Virus-host interactions in activated sludge (AS). A Relative abundances of vOTUs and their hosts grouped by the host taxonomy in each AS ample. AS samples are separated by wastewater types (black lines) and countries (different colors). B, C Linear regression model analysis is performed based on the virus-host abundance correlations for the specific lineage or functional group in each dataset (domestic wastewater: n = 51, industrial wastewater: n = 49, and mixed wastewater: n = 44). Based on linear regression analysis, the R2 values and P values of each dataset in linear regression models are presented in different colors. Two-way ANOVA P values (black font) indicate the significant differences between the three datasets
