Phylogenetic distribution of pogo-related transposases and transposase-derived genes in metazoans. JR and CR indicate that the sequences belong to the JR clade and the CR clades, respectively. Filled-boxes depict pogo-related transposases and empty boxes depict transposase-derived genes. Numbers in the nodes show posterior probabilities (black) and bootstrap values (red). Shaded branches correspond to new CR proteins identified in this work and in d'Alençon et al 2011 (table 1) that have been incorporated to the previously published phylogeny (Casola et al 2008). Dotted lines represent branches not drawn to scale. Trees including nonmetazoans pogo-related transposases and transposase-derived genes are depicted in supplementary figures S2 and S3, Supplementary Material online.
