Project description:Assessment of the seminal fluid proteins of Drosophila mojavensis and Drosophila arizonae. Experiment was performed using SILAC, whereas D. arizonae males were labeled with L-lysine-2HCL, 4,4,5,5-D4 (Lys 4) and D. mojavensis males labeled with L-Lysine-13C6,15N2 (Lys 8) and mated to their respective conspecific females (unlabeled). Following copulation females were immediately frozen in liquid nitrogen and stored at -80 C until reproductive tracts were removed and placed in 50 mM ammonium bicarbonate.

Project description:We utilized three ecologically diverse Drosophila species to explore the influence of ecological adaptation on transcriptomic responses to isocaloric diets differing in their relative proportions of protein to sugar. Drosophila melanogaster, a cosmopolitan species that breeds in decaying fruit, exemplifies individuals long exposed to a Western diet higher in sugar, while the natural diet of the cactophilic D. mojavensis, is much lower in carbohydrates. Drosophila arizonae, the sister species of D. mojavensis, is largely cactophilic, but also utilizes rotting fruits that are higher in sugars than cacti. We exposed third instar larvae for 24 hours to diets either (1) high in protein relative to sugar, (2) diets with equal amounts of protein and sugar, and (3) diets low in protein but high in sugar. As we predicted, based upon earlier interspecific studies of development and metabolism, the most extreme differences in gene expression under different dietary conditions were found in D. mojavensis followed by D. arizonae. No differential expression among diets was observed for D. melanogaster, a species that survives well under all three conditions, with little impact on its metabolism. We suggest that these three species together provide a model to examine individual and population differences in vulnerability to lifestyle-associated health problems such as metabolic syndrome and diabetes.

Project description:In order to polish a long-read genome assembly, short-read illumina data was obtained from Heterodera schachtii cysts (Woensdrecht population from IRS, the Netherlands). Cysts where obtained from infected plant material. Nematodes were cleaned using a sucrose gradient centrifugation step. Thereafter DNA was extracted and used for library preparation and sequencing by Illumina NextSeq500.

Project description:Replication of the eukaryotic genome requires the assembly of thousands of replisomes that must work in concert to accurately replicate a cell’s genetic and epigenetic information. Defining replisome-associated proteins is a key step in understanding how genomes are replicated and repaired in the context of chromatin to maintain genome stability. To identify replisome-associated proteins, we performed iPOND (Isolation of Proteins on Nascent DNA) coupled to quantitative mass spectrometry in Drosophila embryos and cultured cells. We identified 76 and 416 replisome-associated proteins in post-MZT embryos and Drosophila cultured S2 cells, respectively . By performing a targeted screen of a subset of these proteins, we demonstrate that BRWD3, a targeting specificity factor for the DDB1/Cul4 ubiquitin ligase complex (CRL4), functions at the replisome to promote replication fork progression and maintain genome stability. Altogether, our work provides a valuable resource for those interested in the DNA replication, repair and chromatin assembly during development.
