RNRs in viral metagenomes. Heatmap representation of the relative abundance of RNR classes among sequenced viral metagenomic data sets, ranging from low abundance (blue) to high abundance (red). The normalized abundance values are summed over all genes belonging to each RNR class. Viral metagenomes with ≤ five RNR hits are not shown [28,86,91-93,104-111].
