Sample GSM8016844 Query DataSets for GSM8016844
Status Public on Jan 19, 2024
Title PHYB-GFP/AbCDE, 5 minutes, rep 1
Sample type SRA
 
Source name 6-day-old etiolated seedlings (at 17 °C). Following a red light pulse at 50 µmol m-2 s-1 fluence rate for 5 min.
Organism Arabidopsis thaliana
Characteristics tissue: 6-day-old etiolated seedlings (at 17 °C). Following a red light pulse at 50 µmol m-2 s-1 fluence rate for 5 min.
genotype: PHYB-GFP/AbCDE
treatment: red light pulse at 50 µmol m-2 s-1 fluence rate for 5 min.
Treatment protocol Following a red light pulse at 50 µmol m-2 s-1 fluence rate for 5 min, seedlings were fixed in 1 % (v/v) formaldehyde solution.
Growth protocol Surface sterilised seeds were sowed on half-strength MS media and stratified for 3 days at 4 °C. Germination was induced by white light treatment for 6 h, then the plates were incubated in the darkness for 6 days at 17 °C.
Extracted molecule genomic DNA
Extraction protocol The ChIP protocol by Werner Aufsatz (https://www.epigenome-noe.net/researchtools/protocol.php_protid=13.html) was applied with the following modifications. Chromatin samples were sonicated on ice six times for 10 s using a Vibra Cell sonicator (SONICS & MATERIALS Inc., Danbury, CT, USA) at 10% power. Sonicated and diluted chromatin samples were pre-cleared by 20 µl (bed volume) of binding control agarose beads (Chromotek GmbH, Germany) for 1 h at 4 °C. Chromatin was precipitated using 12.5 µl (bed volume) of GFP-Trap agarose beads (Chromotek GmbH, Germany) for 16 h at 4 °C. Precipitated chromatin was eluted from the beads, de-crosslinked and DNA was extracted using the NucleoSpin® Gel and PCR Clean-up kit (Macherey-Nagel, Düren, Germany) with Buffer NTB (Macherey-Nagel, Düren, Germany).
Library preparation was performed using NEBNext Ultra II DNA Library Prep Kit for Illumina (New England BioLabs) along with NEBNext Multiplex Oligos for Illumina (Index Primers Set 1 and 2, New England BioLabs) according to the manufacturer’s protocol. Final libraries were quality checked using D1000 ScreenTape and Reagents on TapeStation 2200 (all from Agilent); quantification was performed using Qubit dsDNA BR Assay kit (Thermo Fischer Scientific). Sequencing was performed on Illumina NextSeq 1000 instrument.

Data processing Sequence reads were trimmed using TrimmomaticPE.0.39 with this parameters:ILLUMINACLIP:TruSeq3-PE-2.fa:2:30:10, LEADING:5 TRAILING:5, SLIDINGWINDOW:5:20, MINLEN:50.
Quality controlled reads (FastQC), were mapped to reference genom using bowtie v2.4.2
PCR duplicates were identified with PicardTools MarkDuplicates v.2.24.
Peaks were called using MACS2 v.2.2.7.1 with the significance cutoff <=0.05 with 147 base pair exact size.
