Table 2 Summary of the documented induction/repression conditions for the S. cerevisiae promoters chosen for the GFP-reporter constructs

HXT1

Low-affinity hexose transporter

Snf3p/Rgt2p

High glucose (4% w/v)^a

Low glucose (0.1% w/v)

[20]

HXT2

High-affinity hexose transporter

Snf3p/Rgt2p

Low glucose (0.1% w/v)

High glucose (4% w/v)

[20]

HXT4

High-affinity hexose transporter

Snf3p/Rgt2p

Low glucose (0.1% w/v)

High glucose (4% w/v); more glucose-repressed than HXT2

[20, 77]

SUC2

Invertase

SNF1/Mig1p

Low glucose (0.1% w/v)

High glucose (2% w/v) and depleted glucose (0% w/v)

[78]

CAT8

Alternative carbon source response-activator

SNF1/Mig1p

Low glucose (0.2% w/v)

High glucose (4% w/v)

[79]

TPS1

Trehalose-6-phosphate synthase (56 kD subunit)

cAMP/PKA

Glucose limitation, stress conditions (e.g. heat, nutrient starvation, oxidative stress)

High glucose; however, a basal expression level has been observed when growing on rapidly fermentable sugars

[80, 81]

TPS2

Trehalose-6-phosphate synthase (102.8 kD subunit)

cAMP/PKA

TEF4

Translation elongation factor

cAMP/PKA
