Sample GSM4802054 Query DataSets for GSM4802054
Status Public on Aug 19, 2021
Title AS2_mC_liver_run2
Sample type SRA
 
Source name homogenised adult liver tissue
Organism Aulonocara stuartgranti
Characteristics tissue: liver
Sex: female
type: wild-caught
Extracted molecule genomic DNA
Extraction protocol Genomic DNA extracted using phenol/chlorophorm approach (see SUPP methods)
DNA strand-specific library using methylated adaptor (NEB) followed by bisulfite conversion (Imprint, Sigma), according to manusfacturer's instructions. WGBS libraries contain lambda genome spike-in control (0.2% w/w).
 
Library strategy Bisulfite-Seq
Library source genomic
Library selection RANDOM
Instrument model Illumina HiSeq 2500
 
Description WGBS from adult tissue
AS_l_n2_50bpmean_SNPcorr.bw
Data processing RNAseq reads were mapped to MZ_UMD2a and gene expression values were calculated using kallisto (see SUPP methods)
WGBS reads were mapped to mapped to SNP-corrected genomes (based on MZ_UMD2a) and methylation levels at CG site were called using Bismark after quality check and adaptor seq removeal using TrimGalore (see SUPP Methods). Methylation at CG sites with ≥5 ≤100 non-clonal seq reads averaged across 50bp-long non-slidding windows per species were performed to produce bw files.
Species-specific high-confidence SNP-corrected genome (fa file) was generated for each of the species studied in this study by using published whole genome sequencing dataset (Malinsky et al 2018); see Methods.
DMRs were called using DSS (see SUPP Methods). P<0.05, minimal overall methylation difference across any DMR between any species was >25% (d25pc), ≥4 CpG, ≥50bp and pvalue<0.05 (p005). For DMR calling, all CG sites were used independent of sequencing coverage following DSS recommandations (improved DMR calling).
Genome_build: Maylandia zebra MZ_UMD2a and SNP-corrected genomes
