title: The GTS1 gene product facilitates the self-organization of the energy metabolism oscillation in the continuous culture of the yeast Saccharomyces cerevisiae.
abstract: To study the role of the GTS1 gene in the energy metabolism oscillation in continuous cultures of yeast from the physical aspect, time-series data of dissolved oxygen oscillations were analyzed by transforming them into power spectra and by creating two-dimensional trajectories using time delay embedding technique. We found that the wild-type cells organized themselves into a stable limit cycle oscillation and that the GTS1-deleted mutant, gts1Delta, usually showed transient oscillations whose power spectra resembled those of 1/f noise. Thus, we suggested that GTS1 plays an important role in the self-organization of the energy metabolism oscillation.
