Fig. 2: Distribution of antiviral systems in prokaryotic genomes.
From: Systematic and quantitative view of the antiviral arsenal of prokaryotes
a Distribution of the total number of antiviral systems per genome. The x-axis was cut at 20 for data visualization purposes. Max number is 57 (Desulfonema limicola). b Average number of antiviral systems (blue) and number of families of antiviral systems (gray) are correlated with genome size (two-sided Spearman, ρ = 0.25 and ρ = 0.44, both p-values < 0.0001 on all sizes; ρ = 0.27 and ρ = 0.30, p-value < 0.0001 for the 2 Mbp–5 Mbp interval) (CI = 95%). Bottom plot, distribution of the genome size. c Average number of antiviral systems (blue) and number of families of antiviral systems (gray) are correlated with number of prophages (two-sided Spearman, ρ = 0.16 and ρ = 0.27, both p-values < 0.0001) (CI = 95%). Bottom plot, distribution of the number of prophages in genomes.
