Project description:Gene expression level of Clostridioides difficile (C. difficile) strain R20291 comparing control C. difficile carring pMTL84151 as vector plasmid with C. difficile conjugated with a pMTL84151-03890 gene. Goal was to determine the effects of 03890 gene conjugation on C. difficile strain R20291 gene expression.
Project description:We isolated suppressors of a ∆ddl mutant strain with constitutively active allelles of the vanS gene. VanS is a histidine kinase of a two-component system that regulates expression of the vanG operon. Transcriptomes of wild-type and ∆ddl vanS (R334L) strains were compared.
Project description:Metabolomic and transcriptomic analysis of changes in the exponential and stationary phase of Clostridioides difficile after cultivation in casamino acids medium (reference) and supplemented with L-lactate and the connection to toxin production.
Project description:The experiment intends to reveal the difference in gene expression profiles between the wild-type strain and the ∆rpoN mutant of Clostridioides difficile. We first constructed the ∆rpoN mutant, and the phenotypic changes of the ∆rpoN mutant against the wild-type strain were studied. To further elucidate the mechanism of phenotypic changes of the ∆rpoN mutant, RNA-sequencing experiments were carried out to reveal the underlying mechanism of phenotypic changes.
