| Title |
MBO22 (C) rep2 |
| Sample type |
SRA |
| |
|
| Source name |
Bacteria planktonic culture harvested at OD600nm 0.8.
|
| Organism |
Streptococcus pneumoniae |
| Characteristics |
strain: MBO22
hsds allele: C
hsds allele target recognition domains: 1.2 and 2.2
colony phenotype: 100% transparent
|
| Growth protocol |
For each pneumococcal strain, three independent cultures were grown in 8 mL of Todd-Hewitt broth supplemented with 0.5 % yeast extract in a 37°C water bath. Cultures were harvested at mid-log phase (OD600nm 0.8), centrifuged (12,000 rpm) for 5 min and resuspended in 1 mL PBS containing lysozyme (2 mg/mL). Samples were immediately processed for RNA extraction.
|
| Extracted molecule |
total RNA |
| Extraction protocol |
RNA was extracted from bacteria pellets with lysozyme, followed by clean-up and DNase I treatment with NucleoSpinRNA II kit kit per manufacturer’s recommendations.
The ribosomal RNA was removed from the total bacterial RNA using ribosome reduction for Gram positive bacteria (ArrayStar, Rockville MD). The purified RNA was then processed using the SureSelect Strand Specific RNA-Seq library prep kit from Agilent Technologies (San Diego, CA) following the manufacturer’s protocol. The resulting libraries were quantitated with quantitative PCR (KapaBiosystems, Woburn MA) and the size distribution of the inserts were checked on the Agilent 2100 BioAnalyzer on a High Sensitivity DNA Chip. Library concentration was normalized to 2nM

| Data processing |
Illumina Casava (bcl2fastq) version 1.8.4 software used for basecalling.
Reads were mapped to the reference S. pneumoniae TIGR4 genome (accession- NC_003028.3) using Bowtie2 2.2.9 (default parameters), and transcript abundance was calculated using summarizeOverlaps function from R package GenomicAlignments
The differential expression analyses were carried out using R package DeSeq2 alognwith generation of normalized read count matrix
Genome_build: NC_003028.3
Supplementary_files_format_and_content: Normalized read count matrix for all samples
