Update of the list of qualified presumption of safety (QPS) recommended microbiological agents intentionally added to food or feed as notified to EFSA 23: Suitability of taxonomic units notified to EFSA until September 2025

EFSA Journal, Volume 24, Issue 1, January 2026.
Abstract The qualified presumption of safety (QPS) process was developed to provide a harmonised safety assessment approach to support EFSA Scientific Panels and Units. The QPS approach assesses the taxonomic identity, body of relevant knowledge and safety of microorganisms intentionally added to the food and feed chain.

Rad27/FEN1 prevents accumulation of Okazaki fragments and ribosomal DNA copy number changes

FEBS Letters, Volume 599, Issue 24, Page 3669-3684, December 2025.
The budding yeast Rad27 is a structure‐specific endonuclease. Here, the authors reveal that Rad27 is crucial for maintaining the stability of the ribosomal RNA gene (rDNA) region. Rad27 deficiency leads to the accumulation of Okazaki fragments and changes in rDNA copy number.

Population genomics of the fission yeast Schizosaccharomyces pombe. [PDF]

PLoS ONE, 2014
The fission yeast Schizosaccharomyces pombe has been widely used as a model eukaryote to study a diverse range of biological processes. However, population genetic studies of this species have been limited to date, and we know very little about the ...

Coming to Terms: The Mechanisms of Overplus and Luxury Phosphorus Uptake for Polyphosphate Storage in Microalgae and Yeast

Biotechnology and Bioengineering, Volume 122, Issue 12, Page 3486-3495, December 2025.
Plouviez et al. give a perspective on the terminology used for describing the mechanisms of polyphosphate accumulation in microalgae and yeast. Their differentiation of mechanisms is based on environmental P availability, polyP chemistry, genetics, or cellular function as described in recent literature.

DNA Preparation from Schizosaccharomyces pombe [PDF]

Cold Spring Harbor Protocols, 2017
This protocol includes two methods for genomic DNA preparation from Schizosaccharomyces pombe. The first is a quick method for preparation of DNA suitable for polymerase chain reaction (PCR) genotyping. The second, longer method yields high-quality DNA that can be used for amplification of targeting cassettes.

Optimisation of the Schizosaccharomyces pombe urg1 expression system. [PDF]

PLoS ONE, 2013
The ability to study protein function in vivo often relies on systems that regulate the presence and absence of the protein of interest. Two limitations for previously described transcriptional control systems that are used to regulate protein expression

Conserved Phosphorylation of the Myosin1e TH1 Domain Impacts Membrane Association and Function in Yeast and Worms

Cytoskeleton, Volume 82, Issue 12, Page 837-849, December 2025.
ABSTRACT Cells have an intrinsic ability to rapidly respond to environmental change to regulate cell cycle progression and membrane organisation, thereby affecting cell growth and division. The actin cytoskeleton is a highly dynamic complex of proteins that can rapidly reorganise to change the growth pattern of a cell.

Multifunctional cytokinesis genes in schizosaccharomyces pombes [PDF]

Acta Biologica Hungarica, 2001
The proper division of cells is essential for the production of viable daughter cells. In plants and fungi, the dividing cell produces a cross-wall or septum that bisects the cytoplasm. For separation of the daughter cells, the septum has to be cleaved. To study the regulation of this process, we isolated mutants defective in septum cleavage.

Diverse transposable element landscapes in pathogenic and nonpathogenic yeast models: the value of a comparative perspective

Mobile DNA, 2020
Genomics and other large-scale analyses have drawn increasing attention to the potential impacts of transposable elements (TEs) on their host genomes. However, it remains challenging to transition from identifying potential roles to clearly demonstrating

Engineering Strategies for Fungal Cell Disruption in Biotechnological Applications

Engineering in Life Sciences, Volume 25, Issue 12, December 2025.
ABSTRACT Fungal cell disruption plays a critical role in unlocking a wide range of high‐value intracellular products such as lipids, proteins, pigments, and bioactive compounds. However, lysing fungal cells is far more challenging than breaking bacterial or algal cells due to their robust and highly structured cell walls.
