Schematic providing a summary of host associations for monophyletic Tc1/mariner groups identified during phylogenetic analysis, which are illustrated as collapsed clades. For each clade (except groups containing less than 3 sequences), a schematic summarising the structure of the TEs contained within each group is illustrated, with structural features represented by different coloured rectangles (please see the accompanying key). TIR: terminal inverted repeat, ORF: open reading frame; Znf: zinc finger domain. For the Tc1, PlantMar, mariner and pogo families, pie charts show the proportion of elements extracted from each eukaryote host group. The four minor families Tec, HvSm, DD37E(L31) and TBE do not have pie charts as the number of sequences is very small
