H-NS may directly repress PhilA because repression of hilA in E. coli requires both the upstream .
Thus , H-NS appears to be important for hilA repression by osmolarity .
The small nucleoid-bind-ing protein H-NS represses hilA in response to low-osmolarity .
In exponential phase cells , the results provided evidence that H-NS repress hilA expression .
Interestingly , a partial inhibition of H-NS activity in cells resulted in a signi-ficant induction of hilA expression , up to about 50 % of the expression .
Our work shows that H-NS repress hilA under account for SPI1 gene silencing .
Our work shows that H-NS repress hilA under a set of physiological conditions .
Our work shows that H-NS repress hilA under a set of well-defined environmental .
Finally , in-vitro-transcription data show that IHF interferes with H-NS repression of hilA .
