Title |
E. coli cell, envZ_point_mutant, rep3 |
Sample type |
SRA |
|
|
Source name |
envZ_Val241Gly
|
Organism |
Escherichia coli |
Characteristics |
cell line: envZ_Val241Gly cell type: point mutant genotype: BW25113
|
Treatment protocol |
In the case of CC1_120, CC2_120 and CC3_120 lines, log phase cells of the ancestor were treated with a lethal concentration of ciprofloxacin (50 ng/ml) for 120 minutes. In the case of CC1_0, CC2_0 and CC3_0 lines, log phase cells were treated with ciprofloxacin (50 ng/ml), and harvested immediately (0 minutes).
|
Growth protocol |
Strains were grown in Minimal salts (MS) medium supplemented with 0.1mM MgSO4, 0.54 μg/mL FeCl3, 1 μg/mL Tiamin, 0.2% Cas amino-acids and 0.2% glucose.
|
Extracted molecule |
total RNA |
Extraction protocol |
Cultures were started from single colonies and grown overnight in Erlenmeyer flasks (25 ml minimal medium). Approximately 109 cells (A600 nm ≈ 1) were taken as samples for RNA isolation. RNA was isolated in late exponential phase (OD around 0.8-1). QIAGEN RNA Protect bacteria reagent was used for freezing of samples (Cat. Num.: 76506). Macherey-Nagel NucleoSpin RNA Plant kit was used for RNA isolation (Cat. Num.: 740949.50). And additional DNase treatment was carried out with Ambion DNase I (Cat. Num.: AM2222). All steps were carried out according to the Manufacturer's instructions. Ribo-Zero rRNA Removal Kit (Gram-Negative Bacteria, Cat.Num.: MRZGN126) was used for RNA depletion. SOLiD Total RNA-Seq kit was used for sequencing library generation (Cat. Num.: PN 4445374). All steps were carried out according to the Manufacturer's instructions.

Data processing |
CLC Genomics Workbench v 7.5.1. Sequence reads were trimmed for adaptor sequence/low-quality sequence using CLC genomic benchwork (parameter- Quality limit: 0.05). Trimmed sequence reads were mapped to E. coli strain K-12 MG1655 / U00096.3 using CLC genomic benchwork (parameters- maximum number of mismatches: 2, minimum length: 0.8, similarity fractions: 0.8, unspecific match hit: 10) Reads shorter than 50 bp were excluded. Read count extraction were performed using CLC genomic benchwork. Read count data were then imported into R version 3.0.249 excluding ribosomal DNA (rDNA) genes. Assembly: U00096.3 Supplementary files format and content: Tab-delimited text files include raw gene counts for each Sample.
