In response to AHLs , SdiA activates two Salmonella-specific loci , the rck operon
In response to AHL under laboratory conditions , Salmonella SdiA activates the expression of the rck operon .
In Salmonella , rck is induced by SdiA .
SdiA upregulates two loci in S. Typhimu-rium , the rck operon , located on the Salmonella virulence plasmid , and srgE -LRB- sdiA-regulated gene -RRB- , a horizontally acquired gene located on the chromosome .
In response to AHLs , SdiA increases the expression of the rck operon .
SdiA increases the expression of the rck operon .
In this study , we first confirmed that the transcriptional regulation of rck by SdiA resulted in an increase of Rck protein expression .
SdiA positively regulates two loci in the rck operon .
SdiA in Salmonella activates expression of the rck operon .
