| Title |
WT-ChIP-1 |
| Sample type |
SRA |
| |
|
| Source name |
whole seedlings
|
| Organism |
Arabidopsis thaliana |
| Characteristics |
developmental satge: 3-day-old
growth conditions: dark-grown
chip antibody: anti-Myc (Abcam, ab9132)
genotype/variation: wild-type
|
| Treatment protocol |
Under green safelight, seedlings were cross-linked in 72 ml of 1% fresh formaldehyde solution for 5 plus 10 min by vacuum infiltration, and then were quenched by adding 5 ml of 2M of glycine with 5 min of vacuum infiltration. Seedlings were rinsed by sterile distilled water, dried by paper towels, and then frozen in liquid nitrogen.
|
| Growth protocol |
0.2 g stratified seeds were irradiated with WL at 21 ºC for 3 h to induce germination and grown in darkness at 21 ºC for 3 d before harvest.
|
| Extracted molecule |
genomic DNA |
| Extraction protocol |
For each PIF-ChIP and each WT control ChIP three independent libraries were generated pooling DNA of four ChIP assays of two biological replicates each using the NEXTflex ChIP-seq kit and 6 NEXTflex ChIP-Seq Barcodes (Bioo Scientific) according to the manufacturer’s instructions. Adapter-ligated DNA-fragments of 200-300 bp were gel-purified, validated by Bioanalyzer 2000 (Agilent) and quantified by the KAPA Library Quantification Kit (KAPABiosystems). Six libraries were pooled on a single lane and sequenced by 50-cycle single-end sequencing on the Illumina HiSeq platform.

| Description |
PIF1-peaks-1.txt
|
| Data processing |
Base-callling was performed using Illumina pipeline CASAVA-1.8.0.
Reads passed quality filtering were aligned to the chromosomes 1-5 of the TAIR10 genome assembly using Bowtie-0.12.7 with the following settings: -v 2 --best --strata -m 1 -5 3
Peak-calling was performed using MACS-1.4.1 with the following settings: -g 150000000 --off-auto --nomodel --shiftsize=60 -w -S.
Genome_build: TAIR10
Supplementary_files_format_and_content: Tabular files generated by MACS containing peaks information, including chromosome name, start position of peak, end position of peak, length of peak region, peak summit position related to the start position of peak region, number of tags in peak region, -10*log10(pvalue) for the peak region, fold enrichment for this region against random Poisson distribution with local lambda, FDR in percentage.
