1 Here, we show that transcription of all AK genes is negatively regulated under darkness and low sugar conditions. Sugars aspartate kinase Saccharomyces cerevisiae S288C
2 Elevated transcript levels of DPBF4 and ABI5 under darkness and low sugar conditions coincide with the repression of AK gene expression. Sugars aspartate kinase Saccharomyces cerevisiae S288C
3 A dominant-negative version of DPBF4 fused to the SRDX repressor domain of SUPERMAN could counteract the repression and stimulate AK expression under low sugar and darkness in planta. Sugars aspartate kinase Saccharomyces cerevisiae S288C
