Expression of lpsS::uidA fusion in the presence and absence of luteolin^a

Strain	Genotype	Luteolinb	Expressionc
Rm1021	Wild type	+	35.5 ± 2.346
Rm1021	Wild type	−	82.3 ± 71.72
DKR227	lpsS::uidA	+	4,190.4 ± 1,147.15
DKR227	lpsS::uidA	−	3,692.9 ± 258.5

^aActivity is in Miller units (27).

^bCells were cultured in the presence of luteolin (solublized in ethanol) or the equivalent amount of ethanol.

^cβ-Glucuronidase activity was measured in cells cultured to late stationary phase (OD₆₀₀, 2.5).
