Sample GSM1600637 Query DataSets for GSM1600637
Status Public on Feb 04, 2017
Title Rhizophagus NPC exudate time point 24h replicate 3
Sample type SRA
 
Source name germinating spores
Organism Rhizophagus irregularis
Characteristics strain: DAOM197198
treatment: rice NPC Root exudates
growth time post induction: 24 hours
Treatment protocol germinating spores were treated with root exudates and collected 1 hour, 24 hours and 7 days in the same previous conditions.
Growth protocol 80 000 spores were germinated in 40ml of liquid M medium for 2 days in the dark with 2% CO2 before treatment (T0)
Extracted molecule total RNA
Extraction protocol Spores were crushed with a motar and a pestle in liquid nitrogen and mRNA were extracted using RNeasy plant kit (Qiagen), according to the manufacturer instructions.
Samples were sequenced at the Genome and Transriptome platform (Toulouse, France - GeT). mRNA were isolated with polyT beads before processing, libraries were constructed according to the manufacturer's protocol.
 
Library strategy RNA-Seq
Library source transcriptomic
Library selection cDNA
Instrument model Illumina HiSeq 2000
 
Description Sample 15
Data processing For gene expression analysis, we used additional triplicates Illumina libraries from treated samples (germinating spores of R.irregularis with wt/npc rice root exudates at time 0, 1h, 24h , 7d). Reads were mapped to the Gloin1 assembly (Tisserant et al., PNAS, 2013) for calculating gene expression by using RNA-seq functionality of the CLC Genomic Workbench suite. To find the genes significantly upregulated during symbiosis, RPKM (Reads Per Kilobase of exon per Million fragments mapped - Mortazavi et al., 2008) and proportion-based test statistics (Baggerly et al., 2003) with a False Discovery Rate (FDR) correction for multiple testing (Benjamini & Hochberg, 1995) were calculated (settings: minimum mapped read length fraction = 0.95; minimum similarity = 0.98). According to CLC recommendation, genes were considered as significantly up regulated when meeting the requirements of "total difference reads mapped" >10 (parameter proposed by CLC WorkBench to select only significantly expressed genes), RPKM fold change>2 and FDR corrected p value<0.05.
