Sample GSM4473161 Query DataSets for GSM4473161
Status Public on Jul 10, 2021
Title jmj7_H3K4me3_ChIPSeq_IP rep2
Sample type SRA
 
Source name jmj7_H3K4me3_ChIPSeq_IP
Organism Solanum lycopersicum
Characteristics background: Ailsa Craig
genotype/variation: jmj7
develpmental stage: At 38 days after anthesis (dpa)
tissue: Pericarp
chip antibody: H3K4me3 (ab8580, Abcam)
Growth protocol Wild-type tomato and transgenic lines in the Ailsa-Craig background were grown in a greenhouse at 23°C under 16 h light and 8 h dark condition.
Extracted molecule genomic DNA
Extraction protocol Pericarp at the equatorial part of the fruit were collected, immediately cross-linked in 1% formaldehyde for chromatin isolation and Lysates were clarified from sonicated nuclei and protein-DNA complexes were precipitated with antibody.
Libraries were prepared according to Illumina's instructions accompanying the DNA Sample Kit (Part# 0801-0303). Briefly, DNA was end-repaired using a combination of T4 DNA polymerase, E. coli DNA Pol I large fragment (Klenow polymerase) and T4 polynucleotide kinase. The blunt, phosphorylated ends were treated with Klenow fragment (32 to 52 exo minus) and dATP to yield a protruding 3- 'A' base for ligation of Illumina's adapters which have a single 'T' base overhang at the 3’ end. After adapter ligation DNA was PCR amplified with Illumina primers for 15 cycles and library fragments of ~250 bp (insert plus adaptor and PCR primer sequences) were band isolated from an agarose gel. The purified DNA was captured on an Illumina flow cell for cluster generation. Libraries were sequenced on the Genome Analyzer following the manufacturer's protocols.
 
Library strategy ChIP-Seq
Library source genomic
Library selection ChIP
Instrument model Illumina NovaSeq 6000
 
Data processing Illumina Casava1.7 software used for basecalling.
Before read mapping, clean reads were obtained from the raw reads by removing the adaptor sequences. The clean reads were then aligned to Tomato reference genome (version SL3.0) using the BWA program.
Peaks were called using MACS2 software with the following setting: MACS2 callpeak --nomodel -f BAMPE --keep-dup 1 -q 0.05 -B –SPMR --broad --broad-cutoff 0.05.
Genome_build: Tomato reference genome (version SL3.0)
Supplementary_files_format_and_content: bigwig files were generated using MACS2 software.
