Title |
Strain TC_KPN15_rep 1 |
Sample type |
SRA |
|
|
Source name |
Enterobacteria
|
Organism |
Klebsiella pneumoniae |
Characteristics |
cell type: Enterobacteria genotype: pOXA-48 transconjugant dataset batch: First dataset
|
Growth protocol |
We grew the cells in LB medium with continuous shaking. When cultures reached a turbidity of 0.5 (first dataset) or 0.2-0.3 (second dataset) at 600 nm, we collected the cells at 4ºC, pelleted them by centrifugation at 4ºC 12,000 g or 11,000 g for 1 min and immediately froze them at -70ºC.
|
Extracted molecule |
total RNA |
Extraction protocol |
We purified the total RNA from each sample using the NZY Total RNA Isolation kit (NZYTECH) (first dataset) or the Total RNA Mini Kit (BioRad’s Aurum) (second dataset). Then, we determined RNAs concentration using the Qubit RNA Broad-Range Assay following the manufacturer's instructions. Additionally, the quality of the RNA was examined using the Tape-Station system (Agilent). We ribodepleted the RNA and sequenced it at the Wellcome Trust Centre for Human Genetics (WTCHG; Oxford, UK) using the Illumina's NovaSeq6000 platform, resulting in >8 million reads per sample (first dataset), or at SeqCoast Genomics (Portsmouth, NH, USA) with Illumina NextSeq2000, generating >6 million reads per sample (second dataset).

Description |
TC_KPN15.1 KPN15_featureCounts.tsv KPN15_DE_results_raw.tsv
|
Data processing |
We trimmed and adapter-removed the reads with Trim Galore v0.6.4 (-q 20 --length 50 --illumina). We assessed the quality of the reads before and after trimming with FastQC v.0.11.9 and MultiQC v1.11. After annotating the reference genomes with PGAP v2021-07-01.build5508, we mapped the trimmed reads to their corresponding reference genome with BWA-MEM v0.7.17. We inspected the mappings to confirm the appropriate presence or absence of pOXA-48 in the replicates. We obtained the raw counts of reads mapping to each genomic feature (including CDS, ncRNA, tRNA, tmRNA, antisense RNA, RNase P and SRP RNA) with featureCounts from the Rsubread v2.14.2 package. We performed the DE analysis from raw counts using DESeq2 v1.40.1 by comparing the pOXA-48-carrying strain against the pOXA-48-free strain (first dataset) or the pOXA-48ΔlysR-carrying strain (second dataset).
