| Title |
AMX resistant mutant-3 |
| Sample type |
SRA |
| |
|
| Source name |
E. coli bacteria
|
| Organism |
Escherichia coli str. K-12 substr. MG1655 |
| Characteristics |
genotype: AMX resistant mutant
agent: TCS
|
| Treatment protocol |
resistant strains as well as the wild-type strain E. coli K-12 MG1655 were cultured in triplicate in 10 mL liquid LB with 0.2 mg/L TCS at 37 °C for 8 h, shaken at 150 rpm.

| Growth protocol |
liquid LB culture at 37 °C
|
| Extracted molecule |
total RNA |
| Extraction protocol |
Bacterial cells were then harvested by centrifugation at 8000 × g for 10 min. Total RNA was extracted from the mutants using the QIAGEN miRNeasy Mini Kit (QIAGEN, Germany) manufacturer’s protocol with one extra bead-beating step to completely lyse the bacterial cells.
RNA libraries were prepared for sequencing using standard Illumina protocols

AMX-3

| Data processing |
base calling through an integrated primary analysis software called RTA (Real Time Analysis. v1.18).
The NGS QC toolkit (version 2.3.3) was used to treat the raw sequence reads to trim the 3’-end residual adaptors and primers, and the ambiguous characters in the reads were removed. Then, the sequence reads consisting of at least 85% bases were progressively trimmed at the 3’-ends until a quality value ≥ 20 were kept. Downstream analyses were performed using the generated clean reads of no shorter than 75 bp.
The clean reads of each sample were aligned to the E. coli reference genome (NC_000913) using SeqAlto (version 0.5). Cufflinks (version 2.2.1) was used to calculate the strand-specific coverage for each gene, and to analyze the differential expression in triplicate bacterial cell cultures. The statistical analyses and visualization were conducted using CummeRbund package in R (http://compbio.mit.edu/cummeRbund/).
Gene expression was calculated as fragments per kilobase of a gene per million mapped reads (FPKM, a normalized value generated from the frequency of detection and the length of a given gene.
