Sample GSM1377381 Query DataSets for GSM1377381
Status Public on Nov 11, 2014
Title dcl234 nrpd1 smRNAseq rep2
Sample type SRA
 
Source name dcl234 nrpd1 smRNAseq
Organism Arabidopsis thaliana
Characteristics genotype/variation: dcl 234 nrpd1
tissue: unopened flower buds
molecule subtype: RNA from 15-40nt
Growth protocol Plants were grown with 16hr of light
Extracted molecule total RNA
Extraction protocol The total RNA was extracted with trizol, and treated with Dnase I to clean up the genomic DNA contamination
All the libraries were built using True-seq small RNA preparation kits(Illumina) using different RNA input. dsRNA, the Rnase One(Promega) treated rRNA-depleted RNA. RNAseq and RNAseq-DSN , total rRNA-depleted RNA. RNAseq-DSN,the RNAseq libraries were normalized with DSN kit (Evrogen) before sequencing. PolyA+ RNAseq, polyA+ RNA. PolyA- RNAseq, rRNA-depleted polyA- RNA. smRNA, small RNA of size 15-40nt.
 
Library strategy miRNA-Seq
Library source transcriptomic
Library selection size fractionation
Instrument model Illumina HiSeq 2000
 
Description smRNAseq
Data processing For dsRNAseq, RNAseq, RNAseq-DSN, PolyA+ RNAseq, PolyA- RNAseq, the reads were mapped back twice. Firstly, the nonredundant reads without adapter trimming were mapped perfectly using BWA without mismatches. Secondly, the unmapped reads trimmed off adapter were mapped perfectly using BWA without mismatches again. The reads were joined together. For smRNAseq, the reads trimmed off adapters were mapped perfectly using BWA without mismatches. For the reads that mapped to multiple position, they are counted only at one randomly position.
Genome_build: TAIR10
Supplementary_files_format_and_content: Wiggle format files with normalized read densities for each nucleotide. The normalized reads were calculated as RPM(reads per million). Please note that some wig files contain both positive and negative values associated with a given chromosome position since the libraries contain strand information, and file s are viewable in popular genome browsers (IGV browser).
