Conditions that yield a repressive outcome
when pivot is Carbon
 and target is GS2:
GLN_Y and Starvation_Y
GLU_Y and NH4_Y
GLU_Y and NO3_Y
The following may give a strong repressive effect:
Illumination_Y
Starvation_Y
Organ_L
Time_S
Media_T
NH4_Y
NO3_Y
GLU_Y
GLN_Y
Experiments to clarify border between repressive and not
Illumination_Y, Starvation_Y, Organ_L, Time_S, Media_T, NH4_Y, NO3_Y, GLU_N, GLN_Y
Illumination_Y, Starvation_Y, Organ_L, Time_S, Media_T, NH4_Y, NO3_Y, GLU_Y, GLN_N
