Effect of AlgU on expression of flhDC and cydR. qRT-PCR analysis of flhDC (a), and cydR (b) gene expression from BS cultures of the wild-type strain ATCC 9046, the algU mutant SMU88 and the mucA mutant JRA4. The level of flhDC and cydR transcripts was normalized according to the levels of gyrA mRNA, and data are presented as -fold changes of mRNA levels of SMU88 and JRA4 mutant strains relative to those of the wild-type ATCC 9046.
