Most of the sequencing and base-calling services were provide by CloudHealth Genomics, Ltd. (Shanghai).
For RNA-Seq dataset, raw data was aligned to a home maintained rDNA database using Bowtie2 (version 2.1.0) with default parameters to filter out any rRNA sequence. Retained reads were then mapped to genome reference using TopHat2 (v2.1.1) with parameters: --read-realign-edit-dist 0 --max-intron-length 10000 --max-segment-intron 10000 --prefilter-multihits. FPKM value of each gene was calculated using StringTie (v1.3.1c) with parameters: -e -j 3 -f 0.2 -A. Raw read counts of genes were calculated using HTSeq (version 0.9.1) with parameters: --nonunique all.
For DNase-Seq and ChIP-Seq dataset, raw reads were mapped to the genome reference using Bowtie2 (version 2.1.0) with option: -3 100. For DNase-Seq and transcription factor ChIP-Seq datasets, peaks were called using MACS (ver 2.1.1.20160309), with the parameters: --nomodel -q 0.01 and -q 0.01, respectively. For H3K27me3 ChIP-Seq dataset, peaks were called using SICER (version 1.1) with the settings: window size 150, gap size 300, FDR 0.01. H3K27me3 candidate peaks were filtered further by their length, fold of enrichment and FDR: 1. peaks shorter than 300 bp was discarded; 2. for peaks shorter than 1kb, fold of enrichment and FDR requirement cutoff were setted as 5 and 1e-50, respectively for apple and tomato datasets, 4 and 1e-50 repectively for banana, grape and pear datasets, 3 and 1e-5 for datasets of other species; 3. for peaks longer than 1kb, fold of enrichment cutoff were setted as 4 for apple and tomato datasets, 3 for banana, grape and pear datasets, 2 for datasets of other species; Alignments with mapping score less than 10 and PCR duplicates were discarded using samtools before peak calling. bedgraph file generated by MACS with --SPMR enabled was converted to bw file using bedGraphToBigWig.
For Bisulfite-Seq dataset, raw data was mapped to genome reference using BSMAP (version 2.90) with the parameters: -A AGATCGGAAGAGC -w 100 -r 0 -q 10. Methylation ratio of each cytosine was calculated using methratio.py with the parameters: -z -r. The result file was compressed using bgzip and index using tabix.
