Drosophila males modulate the interpulse intervals produced during their courtship songs. These song cycles, which are altered by mutations in the clock gene period, exhibit a species-specific variation that facilitates mating. We have used chimeric period gene constructs from Drosophila melanogaster and Drosophila simulans in germline transformation experiments to map the genetic control of th...

Invasive species are a major cause of ecological damage and commercial losses. A current problem spreading in North America Europe is the vinegar fly Drosophila suzukii. Unlike other Drosophila, it infests non-rotting healthy fruits therefore concern to fruit growers, such as vintners. Consequently, large amounts data about occurrence D. suzukii have been collected recent years. However, there ...

Background: Alzheimer’s disease (AD) is an increasingly prevalent neurodegenerative characterized by protein aggregation in the form of amyloid plaques containing beta-amyloid peptides and neurofibrillary tangles hyperphosphorylated tau protein. The central molecular events underlying AD pathogenesis remain controversial poorly defined. Drosophila melanogaster has emerged as important genetic r...

A 1.9-kilobase region of the period locus was sequenced in six individuals of Drosophila melanogaster and from six individuals of each of three sibling species: Drosophila simulans, Drosophila sechellia and Drosophila mauritiana. Extensive genealogical analysis of 174 polymorphic sites reveals a complex history. It appears that D. simulans, as a large population still segregating very old linea...

Data independent acquisition (DIA) has emerged as a promising mass spectrometry based approach, combining the advantages of shotgun and targeted proteomics. Here we applied a DIA approach (termed SWATH) to monitor the dynamics of the Drosophila melanogaster embryonic proteome upon heat-shock treatment. Embryos were incubated for 0.5, 1 or 3 h at 37 °C to induce heat-shock or maintained at 25 °C...

Understanding the earliest events in speciation remains a major challenge in evolutionary biology. Thus identifying species whose populations are beginning to diverge can provide useful systems to study the process of speciation. Drosophila aldrichi, a cactophilic fruit fly species with a broad distribution in North America, has long been assumed to be a single species owing to its morphologica...

Background: MicroRNAs are a class of small (~22nt) endogenous RNAs that regulate target transcript expression post-transcriptionally. Previous studies characterized age-related changes in diurnal but it is not understood how these regulated, and whether they may be attributed part to microRNA or activity with age. Diurnal RNA age were previously studied.<ns3:...

HIGHLIGHTS The longevity of the female and male Drosophila melanogaster is improved at doses given Aloe vera. Trifluralin has been observed to cause DNA damage, while vera shown reduce damage. reduced larval survival rate, increased rate high concentration.
