Sample GSM8316168 Query DataSets for GSM8316168
Status Public on Nov 04, 2024
Title 2603V/R ∆covR RNA-seq Replicate 2
Sample type SRA
 
Source name 2603V/R
Organism Streptococcus agalactiae
Characteristics strain: 2603V/R
genotype: {delta}covR
Treatment protocol Bacterial pellets are washed with cold PBS containing RNA stabilization reagents (RNAprotect, Qiagen) before flash freezing and storage at -80°C.
Growth protocol Bacterial cultures in rich media (THY) incubated at 37°C in static condition are harvested in exponential growth phase (OD600 = 0.5).
Extracted molecule total RNA
Extraction protocol Total RNA are extracted after cell wall mechanical lysis with 0.1 µm beads (Precellys Evolution, Bertin Technologies) in RNApro reagent (MP Biomedicals), and purified by chloroform extraction and ethanol precipitation.
Depletion of rRNA (FastSelect Bacterial, Qiagen) and libraries construction ((TruSeq Stranded mRNA, Illumina) are done following manufacturer instructions.
 
Library strategy RNA-Seq
Library source transcriptomic
Library selection cDNA
Instrument model Illumina NextSeq 500
 
Description 2603VR_DcovR_Rep2
Data processing Reads were cleaned of adapter sequences and low-quality sequences using cutadapt version 2.10. Only sequences at least 25 nt in length were considered for further analysis.
Bowtie version 2.5.1, with default parameters, was used for alignment on the reference genome
Genes were counted using featureCounts version 2.0.0 from Subreads package (parameters: -t locus_tag -g ID -s 1).
Count data were analyzed using R version 4.0.5 and the Bioconductor package DESeq2 version 1.30.1. The normalization and dispersion estimation were performed with DESeq2 using the default parameters but statistical tests for differential expression were performed with(out) applying the independent filtering algorithm. A generalized linear model was set in order to test for the differential expression between the biological condition. For each pairwise comparison, raw p-values were adjusted for multiple testing according to the Benjamini and Hochberg (BH) procedure and genes with an adjusted p-value lower than 0.05 were considered differentially expressed.
