... versus female niche formation, as these structures form in the absence of dsx function. Instead, dsx acts to ‘tip the balance’ between the male or female programs, which are then executed independently of dsx . We show that bric a brac acts downstream of dsx to control the male versus female niche...

.... Nonetheless, the adult structures differ in both form and function. In Drosophila , one conspicuous morphological difference is that the antenna has fewer distal segments than the leg. We propose that this is due in part to the variations in the regulation of bric a brac . bric a brac is required for joint...

... in ovary morphogenesis, the basal stalks and interfollicular stalks, also form by cell rearrangement utilizing a convergence and extension mechanism. Terminal filament formation depends on the Bric à brac protein, which is expressed in the nuclei of terminal filament cells and is cell autonomously required...
