Sample GSM5857176 Query DataSets for GSM5857176
Status Public on Feb 04, 2022
Title WT_15min_afterInd_37C_rep3
Sample type SRA
 
Source name bacteria grown in Lauria broth
Organism Yersinia pseudotuberculosis
Characteristics strain: YPIII
genotype: wild type
time (minutes): 15
Treatment protocol To reach the virulence induction condition, overnight bacterial cultures were diluted to OD600 0.05 in LB and grown at 26ºC. After 1 h, calcium was depleted by adding EGTA to 5 mM and MgCl2 to 20 mM , and cultures were shifted to 37ºC
Growth protocol All strains were routinely grown at 26ºC in LB medium containing kanamycin (50 µg/ml) to the desired OD600.
Extracted molecule total RNA
Extraction protocol For isolation and purification of RNA, the Trizol method (Ambion Life Technologies, Carlsbad, CA) and the Direct-zol RNA kit (Zymo Research, USA) were used. To remove unwanted DNA, purified RNA was treated with DNAse for 30 min at room temperature according to the manufacturer’s instructions. RNA quantity was measured by Qubit
RNA libraries were prepared for sequencing using RNA-tag seq protocol
 
Library strategy RNA-Seq
Library source transcriptomic
Library selection cDNA
Instrument model Illumina NovaSeq 6000
 
Data processing Reads were trimmed from 5' and 3' ends until all the adapter and low-quality bases were removed and the sequences passed QC checking by FastQC
Reads were aligned to a reference genome of Y. pseudotuberculosis (accession number NC_010465) using bowtie2 with the unique-mapping option.
Post-mapped read quality checking was done using RseQC, and the numbers of reads for each gene were counted using feaatureCount
Aligned reads were converted to BAM and wig by SAMtool and custom script
Differential gene expression was determined using DEseq2, using the shrinkage estimation of dispersion option (lfcSrink =True) to generate more accurate estimates of differential expression in fold changes
