Title |
Vegetative stage replicate 1 |
Sample type |
SRA |
|
|
Source name |
Vegetative cell nuclei
|
Organism |
Dictyostelium discoideum |
Characteristics |
developmental stage: Vegetative strain: AX4
|
Growth protocol |
We cultured te strain at 22 °C shaken in the incubator at 180 rpm in HL5 medium with 300 μg/ml streptomycin
|
Extracted molecule |
genomic DNA |
Extraction protocol |
Frozen pellets of D discoideum cells from the various stages were washed twice with cold PBS and lysed with 10 mM Tris-HCl (pH 7.4), 10 mM NaCl, 3 mM MgCl2, 0.1% Igepal-630 Nuclei were transposed using the Nextera DNA Library Prep Kit. Transposed libraries were amplified for 11 cycles and size selected for fragments ranging 200-1000 bp. ATAC-seq experiments were sequenced to a minimum depth of 10 million reads/sample.

Data processing |
Real-Time Analysis (RTA) software The raw fastq files were trimmed for the first and last 8 nucleotides, the multiqc was use to summarize the fastQC results, and the trimmed files were mapped to the Dictyostelium discoideum genome using bowtie2 The mitochondria genome was removed in the alignment process The duplicated reads were removed by picard and sorted bam files were subject to peak calling with MACS2 Open chromatin regions and peak annotation were deducted with Diffbind and ChIPSeeker, respectively Genome_build: AX4 Supplementary_files_format_and_content: Peak files for open chromatin regions
