Maximum likelihood tree of 101 PolB sequences in the complete reference set

The phylogenetic tree was built using PhyML [] (Jones-Taylor-Thornton substitution model [], 100 bootstrap replicates) based on a multiple sequence alignment generated using M-Coffee []. This tree is unrooted . The phage group was arbitrarily chosen as an outgroup for presentation purposes. The lengths of branches do not represent sequence divergence. Bootstrap values lower than 70% are not shown. The selected 51 representatives for the phylogenetic mapping and the associated branches are highlighted in bold face and black lines, respectively. Different colors correspond to different taxa: viruses (blue), eukaryotes (orange), bacteria (green) and archaea (pink).<p><b>Copyright information:</b></p><p>Taken from "Taxonomic distribution of large DNA viruses in the sea"</p><p>http://genomebiology.com/2008/9/7/R106</p><p>Genome Biology 2008;9(7):R106-R106.</p><p>Published online 3 Jul 2008</p><p>PMCID:PMC2530865.</p><p>
