Relationship between mutation and evolution rates across viruses.

<p>Symbols for each Baltimore group are the same as in <a href="http://www.plospathogens.org/article/info:doi/10.1371/journal.ppat.1002685#ppat-1002685-g001" target="_blank">Figure 1</a>. <b>a</b>: evolution rates versus mutation rates for seven viruses (HSV-1: herpes simplex virus 1; TMV: tobacco mosaic virus; AHBV: avian hepatitis B virus; FLUVA: influenza A virus; HIV-1: human immunodeficiency virus 1; PV-1: poliovirus 1; HCV: hepatitis C virus). <b>b</b>: log-scale mean ± SEM mutation and evolution rates for each Baltimore group. The dotted line indicates the prediction from a purely neutral model, whereas the dashed line corresponds to a model that incorporates deleterious mutations.
