AMR gene copy number per Mbp of assembled metagenomes normalised for microbial communities in wastewater treatment plant effluent, river water, seawater, and communities that colonise LDPE, PET and PP plastics after pre-exposure to wastewater, river water brackish water and seawater at 1-week. Abundance changes are shown by the colour gradient. Significant ANOVA generated p-values for interactions between sample type and ARG are shown on significant heatmap tiles. Statistical significance: ***p < 0.001; **p < 0.01; *p < 0.05, p < 0.1. Based on CARD database [49]
