| Title |

| Sample type |
SRA |
| |
|
| Source name |
Pseudomonas aeruginosa PAO1, Pseudomonas virus 14-1
|
| Organism |
Pseudomonas aeruginosa |
| Characteristics |
cell type: bacterial cell
strain: PAO1
treatment: no enrichment
agent: Pseudomonas virus 14-1
infection stage: infected with phage (samples from different timepoints during infection pooled)
|
| Treatment protocol |
Total RNA was extracted using hot-phenol extraction, followed by DNAse treatment. For each phage, the samples from different timepoints were pooled in equal amounts before starting the library prepartion. The enriched samples were subjected to an enrichment procedure based on streptavidin beads to enrich for primary transcripts. For the control samples the enrichment steps were omitted.
|
| Growth protocol |
P. aeruginosa cells (PAO1/PAK/Li010) were grown to exponential phase in LB medium and infected with the appropriate phage (LUZ19, LUZ24, YuA, PAK_P3, 14-1 or phiKZ). Culture samples were taken at multiple timepoints during infection. The number of samples and the timepoints were decided depending on the duration of the phage infection cycle.

| Extracted molecule |
total RNA |
| Extraction protocol |
All samples, aside from 0 min, were pooled together and homogenized (sample tφ). The resulting samples t0 (uninfected) and tφ (phage infected) were subjected to hot phenol treatment and ethanol precipitation to extract and purify the RNATotal RNA was extracted using hot-phenol extraction, followed by DNAse treatment.
Total RNA was enriched for primary transcripts using the ONT-cappable-seq enrichment protocol. In parallel, control samples were subjected to similar environmental conditions. The RNA was reverse transcribed, PCR amplified and barcoded accoriding to Oxford Nanopore Technology cDNA-PCR protocol (SQK-PCB109)
