Figure 6From: A hidden reservoir of integrative elements is the major source of recently acquired foreign genes and ORFans in archaeal and bacterial genomesORFan distribution. (a) Distribution of ORFans in CAGs: ORFans in CAGs of viral origin (red); ORFans in CAGs of plasmid origin (green); ORFans in CAGs of viral/plasmid origin (yellow); ORFans in CAGs of cellular origin (blue); and ORFans in unassigned CAGs (violet). (b) Proportion of ORFans inside CAGs of different sizes. Data were normalized according to the number of CAGs in each category.Back to article page
