Long‐Term Stress Adaptation as a Highly‐Conserved Key Factor in Yeast Aging
Aging Cell, Volume 25, Issue 5, May 2026.This study shows that long‐term, but not short‐term, stress exposure triggers molecular changes in yeast that mirror established hallmarks of aging, including altered proteostasis, epigenetic shifts, and reduced lifespan. These changes are reversible upon stress removal, and the genes involved are conserved across all domains of life. ABSTRACT Aging is

Global transcriptional response after exposure of fission yeast cells to ultraviolet light
BMC Cell Biology, 2009 Background In many cell types, including the fission yeast Schizosaccharomyces pombe, a set of checkpoints are induced by perturbations of the cell cycle or by DNA damage.

Cell cycle regulation of a Xenopus Wee1-like kinase [PDF]
, 1995 Using a polymerase chain reaction-based strategy, we have isolated a gene encoding a Wee1-like kinase from Xenopus eggs. The recombinant Xenopus Wee1 protein efficiently phosphorylates Cdc2 exclusively on Tyr- 15 in a cyclin-dependent manner.

The Hemoprotein Hhy1 Promotes Heme‐Dependent Catalase Activity of Ctt1
Molecular Microbiology, Volume 125, Issue 5, Page 389-411, May 2026.A Schizosaccharomyces pombe strain deficient in heme (hem1Δ) and siderophore (Fc) biosynthesis, as well as high‐affinity iron (Fe) uptake (blue), was used to uncover the hemoprotein Hhy1 that promotes the heme‐dependent activity of the catalase Ctt1. In contrast, hhy1Δ cells exhibit reduced Ctt1 activity and increased sensitivity to oxidative stress ...

Live Cell Imaging in Fission Yeast [PDF]
Cold Spring Harbor Protocols, 2017 Live cell imaging complements the array of biochemical and molecular genetic approaches to provide a comprehensive insight into functional dependencies and molecular interactions in fission yeast. Fluorescent proteins and vital dyes reveal dynamic changes in the spatial distribution of organelles and the proteome and how each alters in response to ...

To Make a Long Spindle Short: Nuclear Envelope Breakdown during Meiosis
Cell Reports, 2018 In fission yeast, the nuclear envelope (NE) remains intact during mitosis and meiosis I but is compromised during meiosis II. In this issue of Cell Reports, Flor-Parra et al.

Splitting of the fission yeast septum [PDF]
FEMS Yeast Research, 2007 In cell-walled organisms, a cross wall (septum) is produced during cytokinesis, which then splits in certain organisms to allow the daughter cells to separate. The formation and the subsequent cleavage of the septum require wall synthesis and wall degradation, which need to be strictly coordinated in order to prevent cell lysis.

PLoS Genetics, 2008 The fission yeast Schizosaccharomyces pombe Rec12 protein, the homolog of Spo11 in other organisms, initiates meiotic recombination by creating DNA double-strand breaks (DSBs) and becoming covalently linked to the DNA ends of the break.

Pattern selection in a biomechanical model for the growth of walled cells [PDF]
, 2015 In this paper, we analyse a model for the growth of three-dimensional walled cells. In this model the biomechanical expansion of the cell is coupled with the geometry of its wall. We consider that the density of building material depends on the curvature
