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. Assembly: TAIR10 Supplementary files format and content: bw, narrowPeak
