Title |
400-2 |
Sample type |
SRA |
|
|
Source name |
C. elegans RNA
|
Organism |
Caenorhabditis elegans |
Characteristics |
ir treatment: 400Gy
|
Treatment protocol |
Approximately 1000 age-synchronized young adult hermaphrodites (24 h post the L4 larval stage) were irradiated with 0 Gy, 200 Gy and 400 Gy of X-rays using a 600C/D linear accelerator (Varian, USA).
|
Growth protocol |
C. elegans were provided by South China Agricultural University, Guangzhou, Guangdong, China. NGM medium containing 0.3% NaCl, 0.25% peptone, 1.7% agar and 1 M KH2PO4-K2HPO4 solution buffer was used to culture C. elegans according to the standard protocol
|
Extracted molecule |
total RNA |
Extraction protocol |
RNA was harvested using Trizol reagent. Illumina TruSeq RNA Sample Prep Kit (Cat#FC-122-1001) was used with 1 ug of total RNA for the construction of sequencing libraries. RNA libraries were prepared for sequencing using standard Illumina protocols

Data processing |
Illumina Bcl2FastQÂ software used for basecalling. Sequenced reads were trimmed for adaptor sequence, and masked for low-complexity or low-quality sequence, then mapped to GCF_000002985.6_WBcel235 whole genome using Tophat2 v2.0.13 with parameters --read_mismatches 2 --read_gap_length 2 --read_edit_dist 2 Reads Per Kilobase of exon per Megabase of library size (RPKM) were calculated using a protocol from Chepelev et al., Nucleic Acids Research, 2009. In short, exons from all isoforms of a gene were merged to create one meta-transcript. The number of reads falling in the exons of this meta-transcript were counted and normalized by the size of the meta-transcript and by the size of the library. Genome_build: GCF_000002985.6_WBcel235 Supplementary_files_format_and_content: tab-delimited text files include RPKM values and counts for each Sample
