Sample GSM6758123 Query DataSets for GSM6758123
Status Public on Nov 10, 2023
Title set2, AagrOXF 4week thalli, H3, rep2
Sample type SRA
 
Source name thalli
Organism Anthoceros agrestis
Characteristics strain: Oxford
tissue: thalli
age: 4 weeks
genotype: wild type
chip antibody: H3
Growth protocol Plants were cultured on 0.5 Gamborg’s B5 medium solidified with 1% agar under continuous white light at 22°C.
Extracted molecule genomic DNA
Extraction protocol Tissues were fixed with 1% paraformaldehyde for 10 minutes. After quenching and tissue lysis, chromatin was sonicated using a E220 focused-ultrasonicator (Covaris).
ChIP-seq libraries were prepared using the Ovation® Ultralow Library Systems V2. 1-10 ng of DNA was used as starting material for input and ip samples. Libraries were amplified using 12-15 cycles on the thermocycler. Libraries were validated using the fragment analyzer.
 
Library strategy ChIP-Seq
Library source genomic
Library selection ChIP
Instrument model Illumina HiSeq 4000
 
Description TH_Aa_ChIP15
Data processing Self-ligated adaptor sequences were removed by using catadapt with a option --minimum-length 1.
ChIP-seq reads were aligned to the Anthoceros agrestis Oxford genome using Bowtie2 version 2.3.4.2 with options --sensitive -p 8 -N 0 --trim5 0 --trim3 0. Reads with MAPQ less than ten were removed with Samtools v1.9 and duplicates were removed with Picard v2.18.27.
Bigwig files were generated using the bamCoverage function of deepTools v3.3.1 with options --normalizeUsing RPGC --effectiveGenomeSize 122905886 --binSize=10.
Bigwig files of log2 ratio of each mark to input sample were generated using the bamConpare function of deepTools v3.3.1 with options--scaleFactorsMethod readCount --binSize=10.
Peaks were called using MACS2 v2.2.5 with options --nomodel --nolambda -q 0.01 --broad --broad-cutoff 0.1.
Aligned BAM files of each replicate were merged using SAMtools v1.9. These merged BAM files were used to generate bigwig files and MACS2 peak files (used the same method described above)
