Sample GSM951358 Query DataSets for GSM951358
Status Public on Apr 15, 2013
Title rve8_mock_1
Sample type SRA
 
Source name Arabidopsis seedlings
Organism Arabidopsis thaliana
Characteristics age: 7 days old
tissue: whole seedlings
genotype/variation: rve8-1
treatment: mock
Treatment protocol At ZT4 (4 hourse after lights on), meshes with the seedlings were transferred to liquid MS+3% sucrose media containing 30 mM dexamethasone (DEX) or the same volume of solvent (mock). After four hours incubation with gentle agitation, plants were harvested and quickly frozn in liquid nitrogen.
Growth protocol Arabidopiss rve8-1 RVE8::RVE8:GR and rve8-1 seeds (~30 seeds/ per sample) were sterilized and stratified on fine nylon mesh on MS +3% sucrose at 4 degree in the dark for 2 days. Seedlings were grown in 12 hours light (~50 micro Ei white light)/ 12 hours dark for 7 days.
Extracted molecule total RNA
Extraction protocol Total RNA was isolated using trizol and then purified by Qiagen mini-elute column. A customized Illumina-based strand-specific multiplex library construction protocol was used (modified from Wang et al., A Low-Cost Library Construction Protocol and Data Analysis Pipeline for Illumina-Based Strand-Specific Multiplex RNA-Seq, 2011)
 
Library strategy RNA-Seq
Library source transcriptomic
Library selection cDNA
Instrument model Illumina HiSeq 2000
 
Description Sample 10
Data processing Illumina Casava version 1.8 was used for basecalling.
Quality filtering (-q 20 -p 85, minimum quality score to keep: 20, minimum percent of bases that must satify the quality score cut-off: 85) using FASTX-toolkit (command-line)
Remove adaptor contamination using a perl script
De-multiplexing (allow one mis-match in the index sequnce) using "FASTX Barcode Splitter" included in FASTX-toolkit and removed the index sequnce from the reads
The reads were mapped to Arabidopsis cDNA representative_gene_model (TAIR 10) using BWA (aln -l 20, -t 4, using the first 20 subsequnce as seeds, tread number: 4)
Used samtools to combine bam files from the two lanes together and convert to sam files
Separated the reads mapped to forward or reverse strands using command-line
Summarized from the sam files to counts using R
Genome_build: TAIR10 cDNA representative_gene_model
Supplementary_files_format_and_content: sam2counts_RV.txt: COUNTS from reads mapped to the reversed strand in the 12 samples; suitable for edgeR analysis
