Fig. 4From: Regulatory regions in natural transposable element insertions drive interindividual differences in response to immune challenges in Drosophilatdn8 insertion showed increased reporter gene expression. Results of the in vivo enhancer reporter assays for A tdn8, B FBti0018868, and C FBti0061506. Normalized expression levels of the lacZ reporter gene in transgenic female guts with (red) and without (grey) the candidate TE insertions are shown. β-GAL immunostaining (green), and DAPI staining (grey) of guts from transgenic females with and without each candidate TE insertions is also shown.
