Abstract

Diverse Tc1/mariner elements with the DD37E signature have been detected. However, their evolutionary relationship and profiles are largely unknown. Using bioinformatics methods, we defined the evolution profile of a Tc1/Mariner family, which harbors the catalytic domain with the DD37E signature, and renamed it DD37E/Mosquito (MS). MS transposons form a separate monophyletic clade in the phylogenetic tree, distinct from the other two groups of elements with the DD37E signature, DD37E/L18 and DD37E/TRT (transposon related to Tc1), and represent a very different taxonomic distribution from that of DD37E/TRT. MS is only detected in invertebrate and is mostly present in Arthropoda, as well as in Cnidaria, Ctenophora, Mollusca, Nematoda, and Platyhelminthes, with a total length of about 1.3 kb, containing an open reading frame (ORF) encoding about 340 amino acids transposases, with a conserved DD37E catalytic domain. The terminal inverted repeat (TIR) lengths range from 19 bp to 203 bp, and the target site duplication (TSD) is TA. We also identified few occurrences of MS horizontal transfers (HT) across lineages of diptera. In this paper, the distribution characteristics, structural characteristics, phylogenetic evolution, and horizontal transfer of the MS family are fully analyzed, which is conducive to supplementing and improving the Tc1/Mariner superfamily and excavating active transposons.
