These results show that HilD positively controls the expression of the gtgE genes , independently of InvF .
These results show that HilD positively controls the expression of the gtgE genes , independently of HilA .
HilD induces the expression of gtgE , in the absence of other Salmonella-specific regulators .
Thus , HilD positively regulates the expression of the gtgE genes , and positively .
HilD positively regulates gtgE in S. Typhimurium .
HilD induces the expression of gtgE , in E. coli MC4100 .
