Transcription profiling of steady-state yeast cultures response to transient perturbations in carbon source (Chemostat setB)


ABSTRACT: Two time courses after pulses of 0.2 g/l and 2 g/l glucose on cells growing in chemostat with galactose as the carbon source. The reference is sample from the chemostat at time 0.

To understand the dynamics of transcriptional response to changing environments, well defined, easily controlled, and short-term perturbation experiments were undertaken. We subjected steady-state cultures of Saccharomyces cerevisiae in chemostats growing on limiting galactose to two different size pulses of glucose, well known to be a preferred carbon source. Although these pulses were not large enough to change growth rates or cell size, approximately 25% of the genes changed their expression  ...[more]
