Fig. 6From: HilE is required for synergistic activation of SPI-1 gene expression in Salmonella enterica serovar TyphimuriumRegulatory network controlling SPI-1 and flagellar gene expression. While the mechanism is unknown, one possibility is that HilE is repressing Rcs mediated repression of SPI-1 and flagellar gene expression. Not shown are repression of flagellar gene expression by the Rcs system and RtsB and activation of flagellar gene expression by HilDBack to article page
