Histone deacetylases: revealing the molecular base of dimorphism in pathogenic fungi
Alberto Elías-Villalobos et al.Fungi, as every living organism, interact with the external world and have to adapt to its fluctuations. For pathogenic fungi, such interaction involves adapting to the hostile environment of their host. Survival depends on the capacity of fungi to detect and respond to external stimuli, which is achieved through a tight and efficient genetic control. Elías-Villalobos et al. propose that histone acetylation is critical to the proper timing and induction of transcription of the genes encoding factors that coordinate changes in morphology with pathogenesis.

A bacterial volatile signal for biofilm formation
Yun Chen et al.Bacteria constantly monitor the environment they reside in and respond to potential changes in the environment through a variety of signal sensing and transduction mechanisms in a timely fashion. In their recent study (Chen, et al. mBio (2015), 6: e00392-15), the authors demonstrated that the soil bacterium Bacillus subtilis uses acetic acid as a volatile signal to coordinate the timing of biofilm formation within physically separated cells in the community. They also showed that the bacterium possesses an intertwined gene network to produce, secrete, sense, and respond to acetic acid, in stimulating biofilm formation.

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:

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.
