germinated conidia
|
| Organism |
Neurospora crassa |
| Characteristics |

| Extraction protocol |
Preparation of N6-methyladenine-containing DNA for sequencing was performed using a previously reported procedure {Bernstein:2012wx} with the following modifications: 5 μg of genomic DNA from N. crassa strains expressing a Dam fusion was digested with 1 μL of DpnI (NEB, 20 units/μL); ligation to primer 5050 was carried out overnight at 16 °C; amplification reactions of ligated DNA with primer 5051 were performed in triplicate, contained 5 μL dNTPs, and an additional PCR cycle was added to the 2nd and 3rd phase of the PCR protocol (4 and 18 cycles respectively); 3 μg of pooled, amplified DNA was sheared using a Bioruptor (Diagenode) twice on high for 10 minutes (30 seconds on/off) at 4 °C; biotinylated DNA was purified using 250 μL slurry of streptavidin-agarose beads (Sigma).

Library strategy: DamID-seq
ChIP-seq processing: All sequencing reads were mapped to the corrected N. crassa OR74A (NC12 genome) (Galazka et al., 2016) using Bowtie2 (Langmead and Salzberg, 2012). ChIP-seq read coverage was averaged, normalized, and analyzed using tools available from deepTools2 on the open-source platform Galaxy (Afgan et al., 2016). Sequencing tracks are displayed as 25-nt-window TDF or bigWig files with the Integrative Genomics Viewer (IGV) (Robinson et al., 2011).
RNA-seq processing: Tools available on Galaxy {Afgan:2018gf} were used to map mRNA-sequencing reads (intron size < 1kb) {Dobin:2012fg} against the corrected N. crassa OR74A (NC12) genome {Galazka:2016cm}, count the number of reads per gene {Dobin:2012fg} and determine differentially expressed genes with DESeq2 {Love:2014ka}.

Genome_build: Neurospora crassa assembly 12 Fixed (files: neurospora_crassa_or74a_12_genome_FIXED.fasta, and neurospora_crassa_or74a_12_transcripts_FIXED.gtf; files are found in GEO submission GSE71024)
Supplementary_files_format_and_content: ChIP-seq processed data files are bigwig files generated using DeepTools (Ramirez et al., 2016) using a window size of 25bp
Supplementary_files_format_and_content: RNA-seq processed data files are txt files containing normalized counts for 2 replicates each of wild type, ∆set-7 (both from Klocko et al. 2016; GSE82222) and ∆epr-1 and the output file from DESeq2 (Love et al., 2014) with pairwise comparisons of 2 biological replicates from each genotype.
