Sample GSM6716934 Query DataSets for GSM6716934
Status Public on Dec 08, 2022
Title RNA of PAS71 LVX3
Sample type SRA
 
Source name Transcriptome of LVX-treated P. aeruginosa PAS71
Organism Pseudomonas aeruginosa
Characteristics strain: PAS71
condition: LVX-treated sample
tissue: exponential growth phase culture
Treatment protocol LB medium (50 mL) was inoculated with exponential growth phase P. aeruginosa PAS71 at a concentration of 1.0E8 CFU/mL. Levofloxacin were then added at a concentration of either 0 (control) or 0.125 μg/mL, respectively, in triplicate. All six experiment groups were incubated in a water bath shaker at 37 ºC with a shaking rate of 180 rpm for 5 h.
Growth protocol Every 50 mL LB medium was inoculated exponential growth phase of P. aeruginosa PAS71, with the bacterial concentration of 1.0E8 CFU/mL. All the three triplicate experiment groups were incubated in a water bath shaker at 37 ºC with a shaking rate at 180 rpm for 5 hours.
Extracted molecule total RNA
Extraction protocol Cells of P. aeruginosa PAS71 were flash frozen on dry ice, and RNA was harvested using Trizol reagent. Illumina TruSeq RNA Sample Prep Kit (Cat#FC-122-1001) was used with 3 ug of total RNA for the Vonstruction of sequencing libraries.
Strand specific library: The construct method of strand specific library is similar to that of NEB library expect that when synthesizing the second strand cDNA, dTTP is replayed by dUTP. After overhangs of the purified double-stranded cDNA are converted into blunt ends, adenylation of 3’ ends of DNA fragments, NEBNext Adaptor with hairpin loop structure is ligated to prepare for hybridization, the second strand cDNA is digested by USER enzyme. The following step is identical with NEB library construction.
 
Library strategy RNA-Seq
Library source transcriptomic
Library selection cDNA
Instrument model Illumina HiSeq 2000
 
Data processing Raw data (raw reads) of fastq format were firstly processed through in-house perl scripts. In this step, clean data (clean reads) were obtained by removing reads Vontaining adapter, reads Vontaining ploy-N and low quality reads from raw data. All the downstream analyses were based on the clean data with high quality.
Index of the reference genome was built using Bowtie v2.0.6 and paired-end clean reads were aligned to the reference genome using TopHat v2.0.9.
RPKM of each gene was calculated based on the length of the gene and reads count mapped to this gene, Vonsidering the effect of sequencing depth and gene length for the reads count at the same time(Mortazavi et al., 2008).
Assembly: Pseudomonas aeruginosa PAS71
