Transgenic Drosophila melanogaster have been used to model both the physiological and pathological behavior of serpins. When the isolated populations were mixed, “molasses flies” preferred to mate with other molasses flies and … The ability to generate flies expressing serpins and to rapidly assess associated phenotypes contributes to the power of this paradigm. Abstract. Drosophila melanogaster is one of the most well studied genetic model organisms, nonetheless its genome still contains unannotated coding and non-coding genes, transcripts, exons, and RNA editing sites. Abstract. Abstract. Development of mating preference is considered to be an early event in speciation. The cohabitation of Drosophila melanogaster with humans is nearly ubiquitous. Though it has been well established that this fly species originated in sub-Saharan Africa, and only recently has spread globally, many details of its swift expansion remain unclear. Abstract. Abstract. We identified the causal genetic variation for the difference in the thoracic trident pigmentation intensity between two wild-derived strains of Drosophila melanogaster.It was found to be the difference in expression level of ebony, which codes for an enzyme in the melanin-synthesis pathway and has pleiotropic effects on vision and behavior. The fruit fly Drosophila melanogaster is a whole-animal model system that has been used to study how physiological responsiveness is integrated with immunity and how dysregulation of this integration leads to pathology. Abstract.
Here, we overcome this limitation by combining whole-genome polymorphism data from D. melanogaster and divergence data between D. melanogaster and Drosophila yakuba. Drosophila exhibits a circadian rest-activity cycle, but it is not known whether fly rest constitutes sleep or is mere inactivity. It is shown here that, like mammalian sleep, rest inDrosophila is characterized by an increased arousal threshold and is homeostatically regulated independently of the circadian clock. Drosophila melanogaster presents an excellent system in which to investigate whether microbiome composition acts as an agent that drives rapid host genomic adaptation. In this study, mating preference was achieved by dividing a population of Drosophila melanogaster and rearing one part on a molasses medium and the other on a starch medium. Previous studies of the evolution of genes expressed at different life-cycle stages of Drosophila melanogaster have not been able to disentangle adaptive from nonadaptive substitutions when using nonsynonymous sites.
