Each point corresponds to one scaffold. Viral matches (y-axis) were counted as the number of ORFs matching a Nucleocytoviricota-specific HMM at an E value of 10−10. These HMMs come from a previous study18 to which were added specific HMMs from the VOG database and HMMs constructed on Pandoraviridae and Pithoviridae genomes. Cellular matches (x-axis) are the number of DIAMOND BLASTP matches against the cellular RefSeq database with a threshold of 35% of sequence identity and an E value ≤ 10−5. The dashed lines represent the chosen threshold excluding all point under or on the line. a Control dataset. The inset is a zoom of the bottom-left corner of the plot. For clarity, 1 bacterial point with over 1000 cellular matches and 1 viral match are not shown. b Permafrost data. For clarity, 5 points with over 1000 cellular matches are not shown. Source data are provided as a Source Data file.
