... attributed. Summary:   Drosophila   prickle can affect, separately, both the Ds/Ft and the Stan/Fz PCP systems; however, Pk and Sple are not essential for either and do not act as a functional link between the two systems. Drosophila Planar cell polarity Abdomen Dachsous/Fat Prickle...

... ( Fig. 4D ). How do wild-type cells acquire different numbers and dispositions of asymmetric bridges on opposite sides of the cell? In the Drosophila abdomen, in the anterior compartment of each segment, we have argued that the Hh morphogen gradient drives a gradient of Fz activity ( Lawrence et...

...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...

..., followed by two segments with identities ranging between T3 and abdomen. The shift of several segment identities implies that Tc'giant directly or indirectly regulates several Hox genes (i.e. those required for the identities of at least maxilla, labium, T1 and T2). Homeotic function of Tc'giant...
