...Caroline C. G. Fabre; José Casal; Peter A. Lawrence The abdomen of adult Drosophila bears mechanosensory bristles with axons that connect directly to the CNS, each hemisegment contributing a separate nerve bundle. Here, we alter the amount of Engrailed protein and manipulate the Hedgehog signalling...

..., formation of the adult thorax and wound healing. All of these processes require the basic region-leucine zipper (bZIP) transcription factors Jun and Fos. Much less is known about morphogenesis of the fly abdomen, which involves replacement of larval epidermal cells (LECs) with adult histoblasts that divide...

...Nikolay Ninov; Dominic A. Chiarelli; Enrique Martín-Blanco The fusion of epithelial sheets is an essential morphogenetic event. Here,we study the development of the abdomen of Drosophila as a model of bounded epithelia expansion and uncover a complex multistep process for the generation...

.... The other set, the Stan system, encodes Starry night (Stan or Flamingo) and Frizzled. The prevailing view is that the Ds system acts via the Stan system to orient cells. However, using the Drosophila abdomen, we find instead that the two systems operate independently: each confers and propagates polarity...

All cells that secrete the abdominal tergites produced the same amount of Ebony protein, regardless of their position within the segment ( Fig. 4 C). Therefore, in the pupal abdomen, Ebony expression is not spatially regulated and does not correlate...
