Progenitor cell integration into a barrier epithelium during adult organ turnover Open
Barrier epithelial organs face the constant challenge of sealing the interior body from the external environment while simultaneously replacing the cells that contact this environment. These replacement cells—the progeny of basal stem cell…

Odorant binding protein 69a connects social interaction to modulation of social responsiveness in Drosophila Open
Living in a social environment requires the ability to respond to specific social stimuli and to incorporate information obtained from prior interactions into future ones. One of the mechanisms that facilitates social interaction is pherom…

Evolution of mechanisms that control mating in<i>Drosophila</i>males Open
SUMMARY Genetically wired neural mechanisms inhibit mating between species because even naive animals rarely mate with other species. These mechanisms can evolve through changes in expression or function of key genes in specific sensory pa…

<i>dsx<sup>GAL4</sup></i> is expressed in a subset of cells of the midgut. Open
(A) The frequency of cells expressing UAS-RedStinger nuclear DsRed reporter (magenta) varies along the length of the anterior midgut from an adult female. Non-expressing nuclei are marked with DAPI alone (blue). Anterior (a) and posterior …

Generating Customized Transgene Landing Sites and Multi-Transgene Arrays in <i>Drosophila</i> Using phiC31 Integrase Open
Transgenesis in numerous eukaryotes has been facilitated by the use of site-specific integrases to stably insert transgenes at predefined genomic positions (landing sites). However, the utility of integrase-mediated transgenesis in any sys…
