Characteristics of ORFans (black circles) and HOPs (open circles) in γ-Proteobacterial clades of increasing phylogenetic depth. Clade designations (n0-n4) follow those shown in Figure 1, and dashed lines denote values for native genes. (A) Average size (in base pairs). (B) Average %G+C content at the third position of codons (G+C3). Bars represent one standard error.
