Transposable elements (TEs), widespread genetic parasites, pose potential threats to the stability of their host genomes. Hence, the interactions observed today between TEs and their host genomes, as well as among the different TE species coexisting in the same host, likely reflect those that did not lead to the extinction of either the host or the TEs. It is not clear to what extent the expression and integration steps of the TE replication cycles are involved in this ‘peaceful’ coexistence. Here, we show that four Drosophila LTR RetroTransposable Elements (LTR-RTEs), although sharing the same overall integration mechanism, preferentially integrate into distinct open chromatin domains of the host germline. Notably, the differential expressions of the gtwin and ZAM LTR-RTEs in ovarian and embryonic somatic tissues, respectively, result in differential integration timings and targeting of accessible chromatin landscapes that differ between early and late embryonic nuclei, highlighting connections between temporal and spatial LTR-RTEs niche partitionings.
