| Characteristics |
treatment: TCA
time point (minutes): 10
biological replicate: 3

| Treatment protocol |

| Growth protocol |
E. faecalis strains were grown in standardized conditions as described in Fouquier D'hérouel, 2011. For all experiments, the strain frozen at -80°C was streaked on 1.5 % agar plate of Brain Heart Infusion (BHI), grown for 20 h at 37°C and incubated 2 h at room temperature. One single colony was used to inoculate 5 ml of liquid BHI and grown for 18 h at 37°C without agitation. The culture was then diluted 1/500-fold in a pre-warmed BHI liquid medium and grown to an OD600 ranging from 0.27 to 0.33 (OD600 ~ 0.3), as monitored manually on spectrophotometer at 600 nm weight length (Pharmacia Biotech, Novaspec II). At such a density, the bacterial population ranged from ~2 to 4 x 10^8 cfu/mL, as verified by viable cell counts on BHI plates.

| Data processing |
Read mapping using BWA-backtrack (version 0.7.12-r1039).
Structural reference annotation of Enterococcus faecalis V583 chromosome (AE016830.1) was enriched with sRNA annotation from Innocenti et al., 2015.
Read counts were obtained using HTSeq-count (version 0.9.1).
Differential expression analysis R library "DESeq2" and associated "median ratio method" normalization procedure.
DESeq2 p-values were converted into q-values using R library "fdrtool".
RPKM values processed using DESeq-2 with a prior-count of 33.
Genome_build: Enterococcus faecalis V583 chromosome (AE016830.1)
Supplementary_files_format_and_content: TCA_gene_expression.txt: Tab-delimited text file containing for each gene/sample raw data counts, log2rpkm with differential expression analysis results.
