Towards solving the conundrum of plasmid mobility: networks of functional dependencies shape plasmid transfer

M Ares-Arroyo, C Coluzzi, EPC Rocha - bioRxiv, 2022 - biorxiv.org
Plasmids are key drivers of bacterial evolution by transferring genes between cells via
conjugation. Yet, half of the plasmids lack all protein coding genes for this process. We …

Origins of transfer establish networks of functional dependencies for plasmid transfer by conjugation

M Ares-Arroyo, C Coluzzi, EPC Rocha - Nucleic acids research, 2023 - academic.oup.com
Plasmids can be transferred between cells by conjugation, thereby driving bacterial
evolution by horizontal gene transfer. Yet, we ignore the molecular mechanisms of transfer …

Multiple plasmid origin‐of‐transfer regions might aid the spread of antimicrobial resistance to human pathogens

J Zrimec - MicrobiologyOpen, 2020 - Wiley Online Library
Antimicrobial resistance poses a great danger to humanity, in part due to the widespread
horizontal gene transfer of plasmids via conjugation. Modeling of plasmid transfer is …

Pseudogenes in plasmid genomes reveal past transitions in plasmid mobility

DM Hanke, Y Wang, T Dagan - Nucleic Acids Research, 2024 - academic.oup.com
Evidence for gene non-functionalization due to mutational processes is found in genomes in
the form of pseudogenes. Pseudogenes are known to be rare in prokaryote chromosomes …

Diverse mobilization strategies facilitate transfer of non-conjugative mobile genetic elements

JP Ramsay, N Firth - Current opinion in microbiology, 2017 - Elsevier

elements.•Element carriage of a relaxase gene is not a strict requirement for mobilization.•A …

Increased copy number couples the evolution of plasmid horizontal transmission and antibiotic resistance

T Dimitriu, A Matthews, A Buckling - bioRxiv, 2020 - biorxiv.org
Antimicrobial resistance (AMR) in bacteria is commonly encoded on conjugative plasmids,
mobile elements which can spread horizontally between hosts. Conjugative transfer …

Fundamental parameters governing the transmission of conjugative plasmids

J Rodriguez-Grande, MP Garcillan-Barcia, F de la Cruz… - bioRxiv, 2023 - biorxiv.org

Identification of novel origins of transfer across bacterial plasmids

M Ares-Arroyo, A Nucci, EPC Rocha - bioRxiv, 2024 - biorxiv.org
Conjugative plasmids are important drivers of bacterial evolution, but most plasmids lack
genes for conjugation. It is currently not known if the latter can transfer because origins of …
