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