BMP signaling dynamics in the follicle cells of multiple Drosophila species

► Patterning of BMP signaling is diverse in the follicle cells of Drosophila species. ► In most species, signaling diversity correlate with the dynamic expression of the type I receptor thickveins (tkv) .► Ectopic expression of tkv in D. melanogaster can recapitulate the signaling diversity found in other species.
