We constructed a set of recombinant Saccharomyces cerevisiae strains with xylose-fermenting ability. A recombinant S. cerevisiae strain D-XR/ARSdR/XK, in which protein engineered NADP(+)-dependent XDH was expressed, showed 40% increased ethanol production and 23% decrease in xylitol excretion as compared with the reference strain D-XR/XDH/XK expressing the wild-type XDH.

Horizontal transposon transfer (HTT) plays an important role in the evolution of eukaryotic genomes, however the detailed evolutionary history and impact of most HTT events remain to be elucidated. To better understand the process of HTT in closely related microbial eukaryotes, we studied Ty4 retrotransposon subfamily content and sequence evolution across the genus Saccharomyces using short- and long-read whole genome sequence data, including new PacBio genome assemblies for two S. mikatae strains.

The murine hepatitis virus (MHV) is an important model system for studying coronavirus (CoV) molecular and cell biology. Despite this, few reagents for MHV are available through repositories such as ATCC or Addgene, potentially limiting the widespread adoption of MHV as a tractable model system. To overcome some challenges inherent in the existing MHV reverse genetics systems, we developed a plasmid-launched transformation-associated recombination (TAR) cloning-based system to assemble the MHV (strain A59; MHV-A59) genome.

Reverse genetics is a useful tool for studying viruses and developing vaccines for coronaviruses. However, constructing and manipulating the coronavirus genome in can be time-consuming and challenging due to its large size and instability. Homologous recombination, a genetic manipulation mechanism found in organisms, is essential for DNA repair, gene recombination, and genetic engineering.

Precision fermentation processes, especially when using edited microorganisms, demand accuracy in the bioengineering process to maximize the desired outcome and to avoid adverse effects. The selection of target sites to edit using CRISPR/Cas9 can be complex, resulting in non-controlled consequences. Therefore, the use of multi-omics strategies can help in the design, selection and efficiency of genetic editing.
