To investigate the mechanism underlying the expressional regulation of fljB : z66 , gene deletion mutants of FlhDC were constructed in this study .
To investigate whether fljB is regulated by FlhDC like other biphasic S. fliA mutants were affected by the osmotic environment , an ompR mutant was also prepared .
To investigate whether fljB is regulated by FlhDC like other biphasic S. flhDC mutants were affected by the osmotic environment , an ompR mutant was also prepared .
To investigate whether fljB is regulated by FlhDC like other biphasic S. enterica mutants were affected by the osmotic environment , an ompR mutant was also prepared .
