Sample GSM6222428 Query DataSets for GSM6222428
Status Public on Jun 10, 2022
Title SYN4-ChIP-biological replicate 2
Sample type SRA
 
Source name the 7-day-old whole seedlings
Organism Arabidopsis thaliana
Characteristics tissue: the 7-day-old whole seedlings
genotype: Col-0
chip antibody: anti-GFP (Abcam #ab290)
Growth protocol Plants were grown at 21℃ on MS agar plates supplemented with 1.5% sucrose and 0.8% agar.
Extracted molecule genomic DNA
Extraction protocol Briefly, 10 g fresh 7-day-old whole seedlings were cross-linked in the cross-link buffer (0.4 M sucrose, 10m M Tris-HCl (pH8.0), 1m M PMSF, 1 m M EDTA, 1% formaldehyde) for 3×5min using vacuum infiltration and the reaction was terminated in 2 M glycine.
After reverse cross-link, DNA was extracted by phenol-chloroform method and sheared to an average size of 300 bp using a sonicator.Sequencing library was constructed according to the standard Illumina protocol.First,the end was supplemented, adenine was added in the 3 'segment, and then PCR amplification technology was used to build the library.
 
Library strategy ChIP-Seq
Library source genomic
Library selection ChIP
Instrument model Illumina HiSeq 1500
 
Data processing Low-quality and adapter sequences were trimmed from the reads using cutadapt (v1.18) with parameters: -a AGATCGGAAGAGC -A AGATCGGAAGAGC --trim-n -m 50 -q 20, 20.
Then, the reads were mapped to the Arabidopsis thaliana TAIR10 genome using Bowtie2 (v2.3.4.3) with parameters: -N 0 --no-discordant --no-mixed --no-unal.
Samtools (v1.9) was used to transfer the mapping results from sam format to position sorted bam format.
Next, the duplicated reads were removed by markdup from sambamba (v0.6.8).
Bam files were then converted to bigwig files using bamCoverage from the deeptools suite (v3.1.3) with parameters: --normalize using RPKM --binSize 25.
Assembly: TAIR10
Supplementary files format and content: bigWig(bigWig is the binary version of WIG or bedGraph. BigWig stores interval axis information. And correlation score (SCORE), mainly used to view continuous density maps of data in the Genome Browser)
