Subcellular RNA localization during Drosophila embryonic neurogenesis [fractionation-Seq]
We isolated whole embryo, nuclear, and cytoplasmic lysates from Drosophila embryos during early and late embryogenesis In Drosophila melanogaster, cell-type specification during early nervous system development requires precise regulation of gene expression in time and space. To investigate the gene regulation patterns in early neuronal development, we developed a method 'DIV-SortSeq'    to enrich for specific neuroglial cell types for RNA sequencing: from early columnar subdivision and specification, through neuroglial differentiation. DIV-SortSeq recapitulates many of the known protein-coding transcriptome dynamics, as well as novel transcriptional regulatory patterns. We also performed nuclear-cytoplasmic fractionation of whole embryos - Fractionation-Seq - to assess temporal changes in subcellular localization of transcripts during embryogenesis. We present these data as a resource to permit further in-depth investigation into the functional roles of the coding and noncoding transcriptome during early Drosophila neurogenesis. Overall design: Ribodepleted RNA-Seq data from whole embryos, nuclear and cytoplasmic fractions at 6-8h and 18-22h after egg laying (AEL)
