Toward a comprehensive phylogeny for mammalian and avian herpesviruses.

ABSTRACT: With the aim of deriving a definitive phylogenetic tree for as many mammalian and avian herpesvirus species as possible, alignments were made of amino acid sequences from eight conserved and ubiquitously present genes of herpesviruses, with 48 virus species each represented by at least one gene. Phylogenetic trees for both single-gene and concatenated alignments were evaluated thoroughly by maximum-likelihood methods, with each of the three herpesvirus subfamilies (the Alpha-, Beta-, and Gammaherpesvirinae) examined independently. Composite trees were constructed starting with the top-scoring tree based on the broadest set of genes and supplemented by addition of virus species from trees based on narrower gene sets, to give finally a 46-species tree; branching order for three regions withi
