Sample GSM6166515 Query DataSets for GSM6166515
Status Public on May 25, 2022
Title mycelia - H3K4me3_set1_rep2_IP
Sample type SRA
 
Source name mycelia
Organism Ustilaginoidea virens
Characteristics isolate: mutant UvKmt2
growth_condition: potato sucrose agar
treatment: H3K4me3
Treatment protocol The mycelia were crosslinked with 1% formaldehyde for 20 mins and stopped with 125 mM glycine for 5 mins at room temperature.
Growth protocol The WT and all transformed strains derived from the WT were cultured on PSA (potato sucrose agar, potato 200 g/L, sucrose 20 g/L and agar 20 g/L) plates at 28°C under dark conditions.
Extracted molecule genomic DNA
Extraction protocol After the cross-linking was stopped with 125 mM glycine, the mycelia were ground in liquid nitrogen and suspended with the nuclei isolating buffer (10 mM Tris pH 8.0, 10 mM sodium butyrate, 400 mM sucrose, 0.1 mM PMSF, 5 mM β-mercaptoethanol and 1 × proteinase inhibitors). The precipitated nuclei were treated with 1 mL lysis buffer (50 mM HEPES pH 7.5, 150 mM NaCl, 1 mM EDTA, 10 mM sodium butyrate, 0.1% deoxycholate, 1% Triton X-100, 0.1% SDS, 1mM PMSF and 1 × Roche protease inhibitor cocktail) and broken into DNA fragments between 200 -500 bp using Diagenode Vioruptor. After pretreating with 10 μL protein A beads (Thermofisher, 10001D), the supernatant was incubated with anti-H3K4me3 antibody (Abcam, ab1012) for 1 h. Then 20 μL protein A beads were added into the above reaction system to bind anti-H3K4me3 antibody. Two biological repeats were conducted.
The purified DNA was used as libraries construction with the NEBNext Ultra II DNA Library Prep Kit for Illumina (NEB, E7645L).

Data processing High-throughput sequencing was carried out using Illumina Hiseq-PE150 by Novogene Corporation (Beijing, China) for Illumina (Langmead et al., 2009).
The clean read pairs were mapped to the reference genome with Bowtie2 (Version 2.3.5) (Langmead and Salzberg, 2012) , and reads with low mapping quality or multiple positions on the genome were identified and removed by SAMtools (Version 1.9).
Enriched peaks were called by HOMER (Version 4.9.1) with default parameters (Heinz, 2010).
