Fig. 4: The distribution and metatranscriptomic analyses of the putative auxiliary metabolic genes (AMGs).
From: Diversity and ecological roles of hidden viral players in groundwater microbiomes
a A circular bar plot depicts the identified auxiliary metabolic genes (AMGs), colored by functional category. Gray triangles indicate cases where host linkages were identified. b A bubble plot shows the distribution of viruses carrying AMGs across different wells, categorized by AMG type. Bubble size corresponds to the relative abundance of virus-carrying AMG. Oxic and anoxic wells are indicated by blue-sky and olive-green colors, respectively. c Heatmap showing the expression levels of the AMGs, expressed as relative transcript abundance in log10. Color intensity reflects the relative expression level of each viral AMG within a given metatranscriptome sample. Higher relative expression (log10) corresponds to more intense colors. d A stacked bar plot depicting the percentage of KEGG pathway modules that are targeted (blue), or not-targeted (gray) by viruses. e Heatmap representing reconstruction of microbial metabolic pathways for microbial (top) and putative AMGs (bottom). Colors reflect the number of KEGG IDs detected, and pathway completeness is indicated. Terp. & polyk. Biosynth. stands for terpenoid and polyketide biosynthesis, Sec.Met. Biosynth. = for secondary metabolite biosynthesis, and Xenob.biodegrad. = for Xenobiotic Biodegradation. The detailed metabolic reconstruction is provided in Supplementary Data 13.
