Abstract

The extent of transposable element (TE) mobilization in different somatic tissues and throughout diverse species is not well understood. Somatic transposition is often challenging to study as it generates de novo TE insertions that represent rare genetic variants present in heterogenous tissues. Here, we describe experimental approaches that can be applied to address TE mobility in somatic tissues with the use of short- and long-read whole-genome DNA sequencing. Focusing on the analysis of the Drosophilamelanogaster intestinal and head tissues, we provide instructions on how to design, perform, and validate experiments that aim at detecting somatic transposition. In addition to providing examples of protocols, this chapter intends to deliver general experimental guidelines that may be adapted to other flytissues or to other species.
