IP and input libraries were prepared using NEBNext® Ultra™ II DNA Library Prep Kit for Illumina® ChIP on formaldehyde-crosslinked ovaries was performed as previously described (Rozhkiv et al, 2013 - Genes Dev), using 100-200 dissected adult ovaries as starting material and the anti-H3K9me3 (Abcam, ab8898).

Description |
Input of H3K9me3 ChIP-seq from dysgenic F1 progeny
|
Data processing |
ChIP-seq analysis was performed on the Galaxy web-based platform following previously described methods (Han et al, 2015 - Bioinformatics). Illumina adaptors and other low quality sequences were removed using the ‘Trim Galore!’ package. ChIP-seq input and IP filtered data were mapped to the Drosophila genome (dm3) and transposon consensus sequences using Bowtie2, using the -k = 1 parameter. RNA-seq: Paired-end (100-nt-long reads) RNA-seq data were mapped to the Drosophila melanogaster genome (dm3) and the FlyBase and Repbase transposon consensus database using the piPipes package (version 1.5.0; https://github.com/bowhan/piPipes), following the RNA-seq pipeline as previously described (Han et al., 2015 - Bioinformatics). Briefly, libraries were first aligned to ribosomal RNA using Bowtie2. Non-rRNA reads were then mapped to the transcriptome and transposon consensus using Bowtie2. Genome_build: Drosophila melanogaster dm3 Supplementary_files_format_and_content: ChIP-seq: Files contain density coverage of uniquely mapped reads to dm3 Supplementary_files_format_and_content: RNA-seq: Files contain strand-specific density coverage of uniquely mapped reads to dm3
