Identification of Jockey elements horizontal transfer. Consistency graphical representation and dS-ENC graphs obtained from the comparison between species in Jockey-F36 (a), Jockey-F53 (b) and Jockey-F65 (c) representing inferences of HTT. In the graphical matrix, the tree represents the host species and each square represents a pairwise comparison, which is coloured according to p-values calculated for the null hypothesis of VT: red represents significant signals of HTT, and the absence of colour represents VT (p-values indicated within each square). In the dS-ENC plots the black empty circles represent ENC–dS measures of the single-copy orthologous genes, the dotted black lines represent the linear regression of dS-ENC from genes, the dotted red lines represent the cut-off P value of 0.05 and red triangles represents the Jockey dS-ENC comparisons. dS: number of synonymous substitutions per synonymous site. ENC: effective number of codons. Species names are shortened as such: dbus for D. busckii, deug for D. eugracilis, dbip for D. bipectinata, dlac for D. lacertosa, dana for D. ananassae and drho for D. rhopaloa. There is evidence of HTT between all the species in the three Jockey families
