Abstract

Mitochondria are key cell organelles with a prominent role in both energetic metabolism and the maintenance of cellular homeostasis. Since mitochondria harbor their own genome, which encodes a limited number of proteins critical for oxidative phosphorylation and protein translation, their function and biogenesis strictly depend upon nuclear control. The yeast Saccharomyces cerevisiae has been a unique model for understanding mitochondrial DNA organization and inheritance as well as for deciphering the process of assembly of mitochondrial components. In the last three decades, yeast also provided a powerful tool for unveiling the communication network that coordinates the functions of the nucleus, the cytosol and mitochondria. This crosstalk regulates how cells respond to extra- and intracellular changes either to maintain cellular homeostasis or to activate cell death. This review is focused on the key pathways that mediate nucleus-cytosol-mitochondria communications through both transcriptional regulation and proteostatic signaling. We aim to highlight yeast that likely continues to serve as a productive model organism for mitochondrial research in the years to come.

  • Only two C. albicans Rtg targets, DIC1 and PEX11, were found to be upregulated in respiratory-deficient strains of S. cerevisiae, albeit in a manner that does not depend on the Rtg transcription factors.

    “Yet, only two of them—DIC1 and PEX11 were found to be upregulated in respiratory-deficient strains of S. cerevisiae, albeit in a manner that does not depend on the Rtg transcription factors (Epstein et al. 2001; Guaragnella et al. 2018).”

    From Mitochondrial retrograde control of transcription evolves with respiratory stress, metabolic adaptation, and virulence in budding yeasts (2026) · cites this paper as Guaragnella et al. 2018

    The section on RTG-independent retrograde signaling describes upregulation of ATO3 in cells lacking mitochondrial DNA, while the section on mitochondria–nucleus communication describes broader transcriptional changes during respiratory deficiency. Neither passage identifies DIC1 or PEX11, establishes that they are C. albicans Rtg targets, or addresses whether their upregulation in S. cerevisiae is independent of Rtg transcription factors (searched: DIC1, PEX11, C. albicans Rtg targets).

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
