Extracted molecule genomic DNA
Extraction protocol ChIP-seq assays were performed on 4-week-old tomato fourth branch of leaves according to Bio-protocol of Ramirez-Prado, J.S. et al (2021) by using aAnti-RNAPII (Abcam, ab26721), Anti-H3K4ac (Active Motif, 39382), Anti-H3K4me3 H3K4me3 (Millipore 07-473), Anti-H3K4me2 (active motif, 39142), Anti-H3K4me1 (active motif, 39300), Anti-H3K9ac (Millipore, 07-352), Anti-H3K9me2 (Abcam, ab1220), Anti-H3K14ac (Millipore, 07-353), Anti-H3K14me1 (Active Motif, 61510), Anti-H3K18ac (Millipore, 07-354), Anti-H3K23me3 (Active Motif, 61500), Anti-H3K23me1 (Active Motif, 39388), Anti-H3K27ac (Abcam, ab4729), Anti-H3K27me3 (Millipore 07-449), Anti-H3K27me2 (Abcam, 24684), Anti-H3K27me1 (Millipore, 07-488), Anti-H3K36ac (Active Motif, 39380), Anti-H3K36me3 (Abcam, ab9050), Anti-H3K56ac (Active Motif, 39282), Anti-H3K56me2 (Active Motif, 39278), Anti-H3K56me1 (Active Motif, 39274), Anti-H3K79ac (Active Motif, 39566), Anti-H4K5ac (Active Motif, 39700), Anti-H4K8ac (Active Motif, 61104), Anti-H4K12ac (Active Motif, 61531), Anti-H4K16ac (Active Motif, 39930), Anti-H4K20ac (Active Motif, 61531) antibodies.
ChIP-seq libraries were prepared from 10ng of DNA using NEBNext Ultra II DNA Library Prep Kit for Illumina (NEB) according to manufacturer’s instructions. DNA libraries were checked for quality and quantified using an Agilent 2100 Bioanalyzer (Agilent) and subjected to 1 × 75 bp high-throughput sequencing by NextSeq 500 (Illumina).
 
Library strategy ChIP-Seq

Data processing Adapters trimming: Sequencing reads were trimmed with trimmomatic with the following command "java -jar trimmomatic-0.38.jar SE $input $output ILLUMINACLIP:TruSeq3-SE.fa:2:30:10 LEADING:5 TRAILING:5 MINLEN:30"
Read mapping: Trimmed reads data were mapped using bowtie2 v 2.3.5 with the following setting "bowtie2 --very-sensitive" against the genome of SollycM82_v1.0.
Filtering step: Mapped reads were filtered with samtools v.1.9 with the command "samtools view -h -b -q 30 "mapping_quality >= 30"
Duplicate filtering: duplicated reads were removed with samtools v.1.9 with the command "samtools fixmate -m and samtools markdup -r "
Peak calling: peaks of read density were called with macs2 2.2.7.1 with the command "macs2 callpeak -t sample.bam -c Input.bam -g 829069930 -p 0.05 --extsize 150 --bw 500 -B -n --outdir (with respectively narrow or broad mode)
Bigwig generation: read density was scored with deeptools the default bamCoverage paramaters
Assembly: SollycM82_v1.0
Supplementary files format and content: Bamcoverage bigwig for plots generated with ComputeMatrix plotprofile of Deeptools
