Sample GSM1666097 Query DataSets for GSM1666097
Status Public on Apr 30, 2015
Title m6A-DpnII-dark
Sample type SRA
 
Source name Algae cultured in constant dark
Organism Chlamydomonas reinhardtii
Characteristics culture media: Tris-Acetate-Phosphate (TAP)
strain: CC 1609
Growth protocol Wild type Chlamydomonas strain CC 1609, wild type, mt+ (also called 21gr+) was grown in standard Tris-Acetate-Phosphate (TAP) medium in at 25 ÂșC with 220 rpm shaking and constant light.
Extracted molecule genomic DNA
Extraction protocol For enzyme digested samples, CviAII or DpnII are added to 10 U/ug and incubated overnight. Digested DNA is sonicated to ~500 bp segments which is subject to DNA library construction.
Standard DNA sequencing and Stranded RNA-seq protocol from Illumina
 
Library strategy OTHER
Library source genomic
Library selection other
Instrument model Illumina HiSeq 2000
 
Description enzyme-treated
Data processing After adaptor trimming and quality control, 50 bp sequence reads were mapped to the Chlamydomonas genome Cre4 (JGI 9) using Bowtie v1.0.1
Then MACS2 was introduced to find enriched regions which we called m6A peaks by comparing the reads from IP sample with input sample. FDR cutoff was set to 0.01.
For enzyme-treated samples, 100 bp paired-end reads are mapped by Bowtie V1.0.1,Reads ends are compared with CATG or GATC map in genome-wide.
Methylation ratios are determined by the the reads ends information.
Genome_build: Cre4
Supplementary_files_format_and_content: tdf files are generated by samtools and IGVTools. They can be directly loaded into IGV genome browser to visualize the reads distribution of each sequencing sample.
