Sample GSM7780728 Query DataSets for GSM7780728
Status Public on Feb 26, 2024
Title Bd21-3_H3K4me1_rep1
Sample type SRA
 
Source name Bd21-3
Organism Brachypodium distachyon
Characteristics cell line: Bd21-3
cell type: leaf
genotype: Bd21-3
chip antibody: anti-H3K4me1
Growth protocol The seedlings grown to the 4th leaf stage under 20h (20h light/4h dark) photoperiods, and the samples were harvested at ZT10.
Extracted molecule genomic DNA
Extraction protocol Seedlings were harvested and fixed with the buffer containing 0.4 M sucrose, 10 mM Tris-HCl (pH 8.0), 1 mM EDTA, 1% formaldehyde, and 1 mM PMSF.Chromatin was sonicated into DNA fragments around 200~500-bp in size using lysis buffer containing 50 mM HEPES (pH 7.5), 150 mM NaCl, 1 mM EDTA, 1 mM PMSF, 1% SDS, 0.1% Na deoxycholate, 1% Triton X-100 and Protease Inhibitor cocktail.
The ChIP-seq libraries were constructed by following the manufacturer’s instructions of VAHTSTM Universal DNA Library Prep Kit (Vazyme).
 
Library strategy ChIP-Seq
Library source genomic
Library selection ChIP
Instrument model Illumina NovaSeq 6000
 
Data processing Cutadapt was used to trim the raw ChIP-seq reads to obtain high sequencing qualiyt reads.
Bowtie2 was used to map cleaned reads to the genome of Brachypodium distachyon.
Using SAMtools to sort reads and remove duplicate reads.
MACS2 was utilized to find peaks, and MAnorm was used to find different peaks in mutant compared with WT.
Reads were normalized using the bamCoverage tool in deepTools and using heatmap to exhibit by plotHeatmap tool in deepTools.
Assembly: Brachypodium distachyon (genome version is 3.0, download from http://plants.ensembl.org/)
