Chicken endogenous retrovirus families. Phylogenetic analysis of an RT multiple sequence alignment for all full-length elements was used to delineate chicken ERV families. The neighbor-joining phylogeny is shown; maximum parsimony and maximum likelihood trees were also reconstructed. The names of the taxa (ERV sequences) correspond to the chicken chromosome number, strand, start and end coordinates from the May 2006 build, v2.1 draft assembly from the Washington University Genome Sequencing Center, found on the UCSC Genome Browser. Family names and characteristics for the 11 novel ERV families discovered here are shown below the tree. Family copy numbers are indicated along with the family averages of intra-element percent identity between 5' and 3' LTRs and their age ranges (lower-to-upper bounds). For each family, percent support values are shown for the internal branch that subtends the family based on bootstrap analysis, for neighbor-joining and maximum parsimony, and the approximate likelihood ratio test for maximum likelihood.
