HT analysis of IT transposons. a Phylogenetic tree based on alignment of the nucleotide sequence of IT transposons. The phylogenetic tree was inferred using the maximum likelihood method with the IQ-TREE program (http://iqtree.cibiv.univie.ac.at), and the DD34E/Tc1 family was used as the outgroup, the identity calculation of each cluster was done using MEGA7. Only consensus or representative sequences were used in this analysis. b Horizontal transfer of IT transposons. The distance was obtained from all possible pairwise comparisons (n = 629; marked on the x-axis) between the 35 (cluster 2), five (cluster 3), three (cluster 4) and seven (cluster 5) species in which IT motifs were identified and complete. The coding sequence (CDS) of the RAG1 gene from the NCBI database is available in Supplementary Table S2
