Genetic basis of I-complex plasmid stability and conjugation
PLoS Genetics, 2023 Plasmids are major drivers of increasing antibiotic resistance, necessitating an urgent need to understand their biology. Here we describe a detailed dissection of the molecular components controlling the genetics of I-complex plasmids, a group of ...

Mechanistic insights into plasmid transfer inhibition in Enterobacterales by nucleoside analogues [PDF]
npj Antimicrobials and ResistanceAntimicrobial resistance (AMR) poses a major global health threat, with carbapenem-resistant and extended-spectrum β-lactamase (ESBL)-producing Enterobacterales causing widespread infections and deaths. Much of this resistance spreads through conjugative

Conjugation-based genetic manipulation of Fusobacterium animalis
mBioFusobacterium is an oncobacterium associated with colorectal cancer (CRC) development. Despite that F. animalis (Fa) dominates the CRC niche in humans, studies on the pathogenesis of Fusobacterium have been limited by the paucity of genetically tractable

Dye‐Conjugated Spinach RNA by Genetic Alphabet Expansion
Chemistry – A European Journal, 2022 AbstractLight‐emitting systems using an RNA aptamer‐dye pair, such as Spinach RNA, are an attractive method for imaging and tracing RNA expression in vitro and in vivo. We present an alternative Spinach method by genetic alphabet expansion using an unnatural base pair system, in which a dye‐conjugated unnatural base substrate is site‐specifically ...

A complex genetic switch involving overlapping divergent promoters and DNA looping regulates expression of conjugation genes of a gram-positive plasmid. [PDF]
PLoS Genetics, 2014 Plasmid conjugation plays a significant role in the dissemination of antibiotic resistance and pathogenicity determinants. Understanding how conjugation is regulated is important to gain insights into these features.

Conjugation-mediated genetic exchange in Legionella pneumophila [PDF]
Journal of Bacteriology, 1985 Genetic exchange mechanisms, to our knowledge, have not been reported for Legionella pneumophila, and consequently, studies on the genetic organization of L. pneumophila have not appeared in the literature. Here, we describe gene transfer mediated by broad host range conjugative plasmids in Legionella spp. Escherichia coli strains carrying plasmids RP1
