Translate to divide: сontrol of the cell cycle by protein synthesis
Michael Polymenis and Rodolfo AramayoProtein synthesis underpins much of cell growth and, consequently, cell multiplication. Understanding how proliferating cells commit and progress into the cell cycle requires knowing not only which proteins need to be synthesized, but also what determines their rate of synthesis during cell division. Experiments with proliferating populations of microbial strains, animal or plant cell lines, have rigorous expectations. Under the same culture conditions, cells ought to have the same properties and composition in every single experiment. The basic “metrics” of proliferating cells remain constant, even after many rounds of cell division. These metrics include cellular mass and volume, and macromolecular composition. The constancy of such parameters reflects the fundamental ability of cells to coordinate their growth with their division. Balancing cell growth with cell division determines the overall rates of cell proliferation…

In the beginning was the word: How terminology drives our understanding of endosymbiotic organelles
OborníkThis In the Pit article argues that the naming conventions for biological entities influence research perspectives and methodologies, advocating for mitochondria and plastids to be classified and named as bacteria due to their endosymbiotic origins, with potential implications for our understanding of bacterial prevalence, definitions of the microbiome and multicellularity, and the concept of endosymbiotic domestication.
What’s in a name? How organelles of endosymbiotic origin can be distinguished from endosymbionts
GruberThis In the Pit article suggests redefining the relationship between hosts and endosymbionts, like mitochondria and plastids, as a single species based on “sexual symbiont integration,” the loss of independent speciation, and congruence in genetic recombination and population sizes, rather than solely on historic classifications or structural properties.

Peer-reviewed, open-access research using unicellular organisms (and multicellular microorganisms) to understand cellular responses and human disease.
The journal (founded in 2014) is led by its Editors-in-Chief Frank Madeo, Didac Carmona-Gutierrez, and Guido Kroemer
Microbial Cell has been publishing original scientific literature since 2014, and from the very beginning has been managed by active scientists through an independent Publishing House (Shared science Publishers). The journal was conceived as a platform to acknowledge the importance of unicellular organisms, both as model systems as well as in the biological context of human health and disease.
Ever since, Microbial Cell has very positively developed and strongly grown into a respected journal in the unicellular research community and even beyond. This scientific impact is reflected in the yearly number of citations obtained by articles published in Microbial Cell, as recorded by the Web of Science (Clarivate, formerly Thomson/Reuters):
The scientific impact of Microbial Cell is also mirrored in a series of milestones:
2015: Microbial Cell is included in the Emerging Sources Citation Index (ESCI), a selection of developing journals drafted by Clarivate Analytics based on the candidate’s publishing standards, quality, editorial content, and citation data. Note: As an ESCI-selected journal, Microbial Cell is currently being evaluated in a rigorous and long process to determine an inclusion in the Science Citation Index Expanded (SCIE), which allows the official calculation of Clarivate Analytics’ impact factor.
2016: Microbial Cell is awarded the so-called DOAJ Seal by the selective Directory of Open Access Journals (DOAJ). The DOAJ Seal is an exclusive mark of certification for open access journals granted by DOAJ to journals that adhere to outstanding best practice and achieve an extra high and clear commitment to open access and high publishing standards.
2017: Microbial Cell is included in Pubmed Central (PMC), allowing the archiving of all the journal’s articles in PMC and PubMed.
2019: Microbial Cell is indexed in the prestigious abstract and citation database Scopus after a thorough selection process. This also means that Microbial Cell obtains, for the first time, an official Scopus CiteScore as well as an official journal ranking in the Scimago Journal and Country Ranking.
2022: Microbial Cell’s CiteScore reaches a value of 7.2 for the year 2021, positioning Microbial Cell among the top microbiology journals (previously available CiteScores: 2019: 5.4; 2020: 5.1).

Sulfur dioxide resistance in Saccharomyces cerevisiae: beyond SSU1
García-Ríos and GuillamónThis article discusses the importance of understanding sulfite resistance in Saccharomyces cerevisiae due to its use in winemaking and the potential role of the transcription factor Com2. While the SSU1 gene and its activity have been correlated with sulfite tolerance, the work by Lage et al. (2019) indicates that Com2 might control a large percentage of the genes activated by SO2 and contribute to the yeast’s protective response, offering new insights into the molecular factors influencing this oenological trait.
