Growth phase- and carbon source-dependent expression of the FBA and XFP genes determined using qRT-PCR

Growth phase or carbon sourcea	Relative gene expression level
	FBA gene	XFP gene
Early log phaseb (OD600, 0.65)	1.00 ± 0.37	1.00 ± 0.31
Mid-log phase (OD600, 1.86)	4.09 ± 0.38	0.35 ± 0.04
Glcb	1.00 ± 0.16	1.00 ± 0.12
Glc and Frc	1.49 ± 0.31	1.52 ± 0.32
Frc	3.65 ± 0.33	3.63 ± 0.39

^aStrain PM1 was cultured in 60 mM glucose (Glc), 30 mM glucose and fructose (Glc/Frc), or 60 mM fructose (Frc) medium for 24 h.

^bControl condition for qRT-PCR.
