Association of texim genes with Helitron transposons in different fish species, plotted on a Texim molecular phylogeny. Texim phylogeny was performed on a 112 amino-acid alignment using the Maximum Likelihood method with 100 bootstraps (values are provided). Blue boxes indicate texim exons, light blue regions encode the SGNH domain. Grey boxes show Helitron transposons, broken boxes indicate that the coding region is corrupted by point mutations. Nucleotide distance between texim and Helitron is provided. Accession numbers are given in the legend of Figure 4.
