Distribution of selected Transposable Elements (TE) within the Dothideomycete phylogeny. The phylogeny is a simplified version of that in Figure 1. Rxx and Dxx correspond to retrotransposons and DNA transposons families respectively. The species in which the family has been identified are highlighted along with the corresponding branches. Colors indicate different times of invasion and are similar to those in Additional file 14: Figure S4.
