Fold change in expression of umoA and umoD in YL1006 compared with BB2000 cells in broth- or soft surface-grown cultures

Gene	Broth		Agar
	Fold change in expressiona	P value	Fold change in expressiona	P value
umoA	1.8 ± 0.4	0.10	1.8 ± 0.4	0.05
umoB	0.9 ± 0.1	0.14	0.9 ± 0.1	0.15
umoC	NDb	NAc	ND	NA
umoD	1.1 ± 0.1	0.21	1.5 ± 0.3	0.04

^aThe fold change in expression (YL1006 versus BB2000) was calculated to compare the expression of each gene (relative to the expression of rpoA, the reference gene) in YL1006 (the ΔfliL mutant) with the expression of the same gene (relative to rpoA expression) in BB2000 (the wild type). A value of >1 indicates that expression of the gene is greater in YL1006 than in BB2000, while a value of <1 means that expression decreases in YL1006. Means ± standard deviations from three independent measurements from three biological samples are presented.
