Identification, Diversity and Evolution of MITEs in the Genomes of Microsporidian Nosema Parasites.

ABSTRACT: Miniature inverted-repeat transposable elements (MITEs) are short, non-autonomous DNA transposons, which are widespread in most eukaryotic genomes. However, genome-wide identification, origin and evolution of MITEs remain largely obscure in microsporidia. In this study, we investigated structural features for de novo identification of MITEs in genomes of silkworm microsporidia Nosema bombycis and Nosema antheraeae, as well as a honeybee microsporidia Nosema ceranae. A total of 1490, 149 and 83 MITE-related sequences from 89, 17 and five families, respectively, were found in the genomes of the above-mentioned species. Species-specific MITEs are predominant in each genome of microsporidian Nosema, with the exception of three MITE families that were shared by N. bombycis and N. antheraeae. On
