|
| Source name |
adult tail (trunk)
|
| Organism |
Danio rerio |
| Characteristics |
tissue: adult tail (trunk)
rna fraction: size fractionated (20-40 nt) whole cell RNA
|
| Extracted molecule |
total RNA |
| Extraction protocol |
Tissues were homogenized and whole cell RNA was extracted using Qiazol (Qiagen) according to the manufacturer.
RiboMeth-seq: 5-10 ug of RNA was partially degraded by alkaline at denaturing temperatures. The size fraction 20-40 nt was purified on gels and linkers added using a system relying on a modified Arabidopsis tRNA ligase joining 2',3' cyclic phosphate and 5' phosphate ends. The library fragments were then sequenced on the Ion Proton platform. See Birkedal U, Christensen-Dalsgaard M, Krogh N, Sabarinathan R, Gorodkin J, Nielsen H.

| Data processing |
Library strategy: RiboMeth-seq
Barcode separation using python script
Adaptor trimming using Cutadapt v. 2.0
Mapping to rRNA reference sequence using Bowtie2 v. 2.3.4.1
Counting read ends and calculating RiboMeth-seq scores using python scripts
The output FASTA files from small RNA-seq were merged and used as the basis of the SNORD search and rRNA interaction prediction. Initially, SNORDs were identified by running the merged FASTA file through snoScan (Schattner et al. 2005) against zebrafish early- and late-rRNA reference sequences (Locati et al. 2017).
Genome_build: early and late zebrafish rRNA (locati et al). The reference sequences are available in the FASTA file on the series record.
Supplementary_files_format_and_content: MS Excel file contains 5' and 3' read count and calculated RiboMeth-seq score at all positions in the rRNA sequence.
