Figure 1 Unrooted Neighbor-Joining Phylogeny Based on the Amino Acid Sequence of the Pol Protein Labels at branch tips represent taxa as provided by the Universal Virus Database, ICTVdB (http://phene.cpmc.columbia.edu; Büchen-Osmond, 2003). Numbers at branch nodes indicate the percentage of bootstrap support for that node based on 1000 replications. Color codes are according to the clade, with the following scheme: ssRNA-RT viruses (red), positive-sense ssRNA viruses (blue), and dsRNA viruses (green). Abbreviations: PRRSV, Porcine reproductive and respiratory syndrome virus. Molecular Cell 2005 17, 61-68DOI: (10.1016/j.molcel.2004.12.009)
Figure 2 Estimation of Dinucleotide Usage Bias χ2 values were calculated at each position upstream of the slippery heptamer. Black line represents the threshold score for a p value of 1% with 15 degrees of freedom. Higher values are more indicative of a significant bias. The first dinucleotide is strongly significant (p value = 6.4 10−11). Molecular Cell 2005 17, 61-68DOI: (10.1016/j.molcel.2004.12.009)
