Fig. 6: Evolution of gammachloroviruses pan-genome.

a COG-sharing network including the 37 gammachloroviruses and all COGs constructed using OrthoFinder, employing bidirectional Blastp with e < 1e-5. Each species is indicated as a bigger spot with different colors. COGs were categorized as: Core genome, as white nodes in the middle of the graph; Accessory genome as light gray nodes around viral species nodes, consisting of COGs found in at least 2 at most 36 viral isolates; and Singletons as dark gray nodes, corresponding to exclusively COGs found in a virus isolate. The graph was generated using a force-based algorithm, with minimal manual organization to allow clear visualization of singletons connections. b Evolution of pan-genome in gammachloroviruses. Pan: number of COGs in pan-genome. Core: number of COGs in core-genome. Viral isolates from the same species are demarcated with different colors. 237 COGs were found in all viruses (core) and 681 COGs were obtained comprising 14062 genes distributed among the 37 isolates.
