Sample GSM4228115 Query DataSets for GSM4228115
Status Public on Apr 25, 2020
Title W306_young_leaf_H3K4me3_rep1
Sample type SRA
 
Source name W306
Organism Oryza sativa
Characteristics tissue: young leaf
development stage: young leaves from two-week old seedlings
cultivar: BASMATI 385
chip antibody: H3K4me3
Treatment protocol Tissues were cross-linked with 1% formaldehyde for 10–15 min and quenched with 0.2 M glycine at room temperature.
Growth protocol Germinating seeds were obtained by soaking dry seeds in water for 72 h at 37 °C. For roots and young leaves, the germinated seeds were grown in a phytotron with the day/night cycle set at 14 h/10 h and a temperature of 32 °C/28 °C. Roots were obtained 7 d after planting on moist filter paper, and young leaves were obtained from 2-week-old plants cultured hydroponically as described34. Approximately 20-d-old seedlings were transplanted to the field and managed under normal agricultural conditions on the experimental farm of Huazhong Agricultural University, Wuhan, China. Mature leaves at the floral induction phase and young panicles were harvested.
Extracted molecule genomic DNA
Extraction protocol Lysates were clarified from sonicated nuclei and protein-DNA complexes were isolated with antibody.
ChIP-DNA was extracted with phenol:chloroform:isoamyl alcohol (Sigma–Aldrich, P3803), precipitated with ethanol, and resuspended in TE buffer. ChIP DNA libraries were prepared using an NEBNext® Ultra™ II DNA library prep kit for Illumina® (New England BioLabs, E7645). Briefly, ChIP DNA was end-repaired, ligated with an adaptor, and followed by 6–10 cycles of PCR amplification, per the manufacturer’s guidelines. Next, library fragments of 250–650 bp were selected using AMPure XP beads (Beckman, A63881). Finally, the DNA fragments were sequenced using an Illumina HiSeq X Ten system (paired-end 150-bp reads)
 
Library strategy ChIP-Seq
Library source genomic
Library selection ChIP
Instrument model HiSeq X Ten
 
Data processing Trimmomatic fitered the raw reads
ChIP-seq reads were aligned to the MSU.7.0/MH63 genome assembly using bwa mem
Data were filtered using the SAMTOOLS MAPQ30 and filter the duplication reads
peaks were called using MACS.2.2.1 with narrow(H3K4me3,H3K27ac,PII)/broad(H3K27me3,H3K4me1,H3K9me2) parameters
