Project description:We used single-embryo metabolomics to characterize early developmental metabolism in Drosophila. We employed a multi-omics approach where samples were collected, homogenized in 80% methanol and the soluble fraction recover to perform targeted metabolomic whle RNA-seq was performed on the insoluble fraction to accurately stage each embryo. Then, this RNA-based staging was used to place single embryo metabolomes across the developmental trajectory. Thus, we are able to construct a highly detailed metabolomic map of embryonic development. Importantly, we validated our single-embryo metabolomics results in pools of 10 embryos. The data provide a continuous timeline of metabolite levels (and gene expression) during early development (0-3 hours) in Drosophila melanogaster. We used two genetically different lines from the Drosophila Genetic Reference Panel (DGRP) with known genetic variations in our crosses (males/DGRP_352, females/DGRP_737). RNA-seq data related to this dataset can be accessed at GEO under accession number GSE263568.
Project description:Full-length, directional RNA-Seq data from a panel of 8 F1 hybid D. melanogaster lines along with matched RNA-Seq data from the two parental lines for one of the F1 crosses. All paternal fly lines were taken from the Drosophila Genetic Reference Panel crossed to a common mother (PMID31308546). Data were collected at three time points (2-4h, 6-8h, 10-12h at 25C) with two biological replicates per collection.

Project description:Investigation of gene expression level changes in evolved polygamous and monogamous populations of Drosophila melanogaster. The populations investigated are described in Hollis et al. 2011. Populations with elevated mutation load do not benefit from the operation of sexual selection. Journal of Evolutionary Biology 24: 1918-1926. A study using total RNA extracted from male and female virgin 4-day old Drosophila melanogaster and then transcriptionally profiled with 12x135k Nimblegen arrays. Also, transcriptional profiling of male and female heads from the same populations using Illumina RNA-Seq.
