The chorion surrounding the embryos subjected to Rp-dpp RNAi frequently shows absence of the operculum and deformities.

Embryos labeled with antibodies against the Toll receptor and Peanut protein, which marks the plasma membrane during the cellularization process. Images acquired using confocal microscopy.

Schematic illustration of the BMP pathway in Drosophila melanogaster, showing receptor activation, Smad-mediated signaling, and its role in gene regulation.

Expression of the engrailed gene in a stage 4 embryo, revealed by in situ hybridization, highlighting the spatial localization of the transcript during embryonic development.

Germ band of the R. prolixus embryo labeled with phalloidin (red) for filamentous actin and nuclei (blue) of the mesoderm, ectoderm, and amnion.

The repetitive muscle pattern in each body segment, revealed by phalloidin staining (filamentous actin).

Spontaneous mutant of R. prolixus showing a red eye instead of the typical black.

The image identifies mutant cells lacking sog expression, marked by the absence of GFP (green). Mutant cell clones were generated using the FLP/FRT system.
