TABLE 3.
Transcriptional profile of ABC transporters during the exponential and the stationary phase interactions.
| Transporter | Genes | Expression |
Description | |
| 12 h | 24 h | |||
| Phosphate and amino acid ABC transporter | ||||
| Phosphate | pstSCAB | Up | Partially Up regulatedb | Upregulation of the phosphate transporter has been previously reported in Salmonella infection of epithelial cells (Hautefort et al., 2008) |
| Lysine/Arginine/Ornithine | argT, hisMQP | Up | Highly Up | The presence of amino acids in the extra cellular environment was co-related to host tissue damage (Hassel et al., 2014). |
| Glutamate/Aspartate | gltIKJL | Up | ||
| General L-amino acid | aapJQMP | Up | Up | |
| Branched-chain amino acid | livKHMGF | Up | Up | |
| Histidine | hisMP a | Partially Up-regulated b | ||
| Mineral and organic ion ABC transporter | ||||
| Alkanesulfonate | ssuACB | Down | ||
| Glycine betaine/Proline | proXWV | Up | ||
| Oligosaccharide and polyol ABC transporter | ||||
| smoEG | Partially up regulatedb | |||
| Monosaccharide transporter | ||||
| Ribose/Autoinducer 2/D-Xylose | rbsBCAD | Up | Partially up regulatedb | Highly up-regulated at 12 h, whereas only rbsB gene was up-regulated at 24 h |
| L-Arabinose | araFHG | Up | ||
| D-Xylose | xylFHG | Up | Partially up regulatedb | Only xylF gene showed noticeable induction at 24 h |
| ABC-2 transporter | ||||
| Lipopolysaccharide | rfbAB | Up | ||
aAll the genes of the ABC transporter were not differentially expressed. Genes that showed variation in their expression levels were presented. bSome of the genes of the ABC transporter showed variation in transcriptional profile.
