The interplay of restriction-modification systems with mobile genetic elements and their prokaryotic hosts

PH Oliveira, M Touchon, EPC Rocha - Nucleic acids research, 2014 - academic.oup.com
The roles of restriction-modification (RM) systems in providing immunity against horizontal
gene transfer (HGT) and in stabilizing mobile genetic elements (MGEs) have been much …

Epigenomic characterization of Clostridioides difficile finds a conserved DNA methyltransferase that mediates sporulation and pathogenesis

PH Oliveira, JW Ribis, EM Garrett, D Trzilova… - Nature …, 2020 - nature.com
Clostridioides (formerly Clostridium) difficile is a leading cause of healthcare-associated
infections. Although considerable progress has been made in the understanding of its genome, …

[HTML][HTML] Diversity of the Pacific Ocean coral reef microbiome

…, C Hochart, N Henry, BCC Hume, PH Oliveira… - Nature …, 2023 - nature.com
Coral reefs are among the most diverse ecosystems on Earth. They support high biodiversity
of multicellular organisms that strongly rely on associated microorganisms for health and …

[HTML][HTML] The chromosomal organization of horizontal gene transfer in bacteria

PH Oliveira, M Touchon, J Cury, EPC Rocha - Nature communications, 2017 - nature.com
Bacterial adaptation is accelerated by the acquisition of novel traits through horizontal gene
transfer, but the integration of these genes affects genome organization. We found that …

Regulation of genetic flux between bacteria by restriction–modification systems

PH Oliveira, M Touchon… - Proceedings of the …, 2016 - National Acad Sciences
Restriction–modification (RM) systems are often regarded as bacteria's innate immune
systems, protecting cells from infection by mobile genetic elements (MGEs). Their diversification …

Conserved DNA methyltransferases: a window into fundamental mechanisms of epigenetic regulation in bacteria

PH Oliveira, G Fang - Trends in microbiology, 2021 - cell.com
An increasing number of studies have reported that bacterial DNA methylation has important
functions beyond the roles in restriction-modification systems, including the ability of …

Marker-free plasmids for biotechnological applications–implications and perspectives

PH Oliveira, J Mairhofer - Trends in biotechnology, 2013 - cell.com
Nonviral gene therapy and DNA vaccines have become the first promising approaches to
treat, cure, or ultimately prevent disease by providing genetic information encoded on a …

Host range and genetic plasticity explain the coexistence of integrative and extrachromosomal mobile genetic elements

J Cury, PH Oliveira, F de La Cruz… - Molecular biology and …, 2018 - academic.oup.com
Self-transmissible mobile genetic elements drive horizontal gene transfer between
prokaryotes. Some of these elements integrate in the chromosome, whereas others replicate …

[HTML][HTML] Analysis of DNA repeats in bacterial plasmids reveals the potential for recurrent instability events

PH Oliveira, KJ Prather, DMF Prazeres… - Applied microbiology and …, 2010 - Springer
Structural instability has been frequently observed in natural plasmids and vectors used for
protein expression or DNA vaccine development. However, there is a lack of information …
