| Extraction protocol |
Poly(A)-selected RNA-sequencing (RNA-seq) was performed on 2.5µg of RNA purified from adult ovaries using the NEBNext® Poly(A) mRNA Magnetic Isolation Module and the NEBNext® UltraTM Directional RNA Library Prep Kit for Illumina®.
Total RNA from adult ovaries was isolated using Trizol reagent (Invitrogen) and quantified by Qubit (Invitrogen)

| Description |
Poly(A)-selected RNA-seq from piwi heterozygous (in Harwich background)
|
| 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.
