The P element invaded rapidly and caused hybrid dysgenesis in natural populations of Drosophila simulans in Japan.

ABSTRACT: Transposable elements not only can change genomic positions and disperse across the gene pool, but also can jump to another species through horizontal transmission. Of late, the P element, a DNA transposon in insects, was shown to cross the genetic boundary from Drosophila melanogaster to D. simulans in Europe around 2006. To understand the dynamics of transposable elements, especially in the early stages of invasion, we examined 63 lines of D. simulans from 11 natural populations in Japan established in 1976-2015. Based on PCR analyses, P elements were demonstrated to exist in Japan in 2008 and later. One copy of the full-length P element was identified and mapped to a site on chromosome 3 L in a genome. All of 18 copies of P elements exami
