TABLE 4.
Expression profile of selected transcriptional regulators and their function.
| Locus tag | Expressiona |
Product | Description | PS coreb | |
| 12 h | 24 h | ||||
| VT47_06065 | Down | DNA-binding transcriptional regulator, IscR family | The regulator is present upstream of iron-sulfur cluster operon (iscSUA). It represses the expression of the iron-sulfur cluster. | Yes | |
| VT47_09405 | Up | IclR family transcriptional regulator | Yes | ||
| VT47_10490 | Up | GntR family transcriptional regulator | No | ||
| VT47_13020 | Up | DNA-binding transcriptional regulator, LysR family | Yes | ||
| VT47_16235 | Up | Flagellar biosynthesis regulator FlhF | It regulates the synthesis of flagellar proteins, and it is essential for the placement and assembly of polar flagella. | Yes | |
| VT47_22635 | Up | Up | AraC family transcriptional regulator | The regulator is present upstream to glycine/betaine ABC transporter genes (proXVW). | Yes |
| VT47_22755 | Down | BetI family transcriptional regulator | This is a transcriptional repressor of betaine regulon. Betaine biosynthesis genes betA/betB are found adjacent to this regulator. | Yes | |
| VT47_24210 | Up | Chemotaxis protein CheY | This CheY family protein is flanked by PhoR/PhoB two-component system and phosphate ABC transporter. | Yes | |
aDifferential expression was investigated during two growth phases of the bacterial pathogen, the exponential phase (12 h) and stationary phase (24 h). bComparison was done with the core genome determined by Baltrus et al. (2011).
