Fig. 4: Gene content of the large genomes recovered from ancient permafrost samples.
From: Past and present giant viruses diversity explored through permafrost metagenomics
For each genome, the position of ORFans (ORFs with no match in the nr database), cellular and viral matches are recorded along the genome. The positions of tRNAs are also shown as red arrows. The pie charts present the proportion and taxonomy of viral matches with slices ≥5% labeled. Groups that match less than 5% of the Unknown Permafrost:M_b2437_k1 scaffold were gathered in “other” except for Pithoviridae. The environmental Pithoviridae/Orpheoviridae-like category contains metagenomic sequences from Bäckström et al.26, 27. The Hydrivirus genome was circularized. Source data are provided as a Source Data file.
