Successful Invasions of Short Internally Deleted Elements (SIDEs) and Its Partner CR1 in Lepidoptera Insects.

ABSTRACT: Although DNA transposons often generated internal deleted derivatives such as miniature inverted-repeat transposable elements, short internally deleted elements (SIDEs) derived from nonlong terminal-repeat retrotransposons are rare. Here, we found a novel SIDE, named Persaeus, that originated from the chicken repeat 1 (CR1) retrotransposon Zenon and it has been found widespread in Lepidoptera insects. Our findings suggested that Persaeus and the partner Zenon have experienced a transposition burst in their host genomes and the copy number of Persaeus and Zenon in assayed genomes are significantly correlated. Accordingly, the activity though age analysis indicated that the replication wave of Persaeus coincided with that of Zenon. Phylogenetic analyses suggested that Persaeus may have evolv
