Staphylococcus aureus temperate bacteriophage: carriage and horizontal gene transfer is lineage associated. [PDF]

open access: yes, 2012
Staphylococcus aureus is a major cause of human and animal infections. Bacteriophage are a class of mobile genetic element (MGE) that carry virulence genes and disseminate them horizontally, including Panton-Valentine leukocidin (PVL), the immune evasion

Comparative study of adenosine 3′‐pyrophosphokinase domains of MuF polymorphic toxins

open access: yesFEBS Open Bio, EarlyView.
With the ultimate goal of understanding the association of toxin‐immunity modules to temperate phages, we characterized toxins from three prophages and examined cross‐protection from immunity proteins. The toxins exhibit adenosine 3′‐pyrophosphokinase activity and are toxic in Escherichia coli.

nec1, a Gene Conferring a Necrogenic Phenotype, Is Conserved in Plant-Pathogenic Streptomyces spp. and Linked to a Transposase Pseudogene

open access: yesMolecular Plant-Microbe Interactions, 1998
We are investigating the genetic basis for, and evolution of, plant pathogenicity in Streptomyces spp. The plant-pathogenic species S. scabies, S. acidiscabies, and S.

Horizontal gene transfer: A critical view [PDF]

open access: yesProceedings of the National Academy of Sciences, 2003
It has been suggested that horizontal gene transfer (HGT) is the “essence of phylogeny.” In contrast, much data suggest that this is an exaggeration resulting in part from a reliance on inadequate methods to identify HGT events. In addition, the assumption that HGT is a ubiquitous influence throughout evolution is questionable.

Phase Diagrams of Quasispecies Theory with Recombination and Horizontal Gene Transfer

open access: yes, 2006
We consider how transfer of genetic information between individuals influences the phase diagram and mean fitness of both the Eigen and the parallel, or Crow-Kimura, models of evolution.

Multiple pathways of plasmid DNA transfer in Helicobacter pylori [PDF]

open access: yes, 2012
Many Helicobacter pylori (Hp) strains carry cryptic plasmids of different size and gene content, the function of which is not well understood. A subgroup of these plasmids (e.g.

A review of artificial intelligence in brachytherapy

open access: yesJournal of Applied Clinical Medical Physics, EarlyView.
Abstract Artificial intelligence (AI) has the potential to revolutionize brachytherapy's clinical workflow. This review comprehensively examines the application of AI, focusing on machine learning and deep learning, in various aspects of brachytherapy.

Does habitat variability really promote metabolic network modularity? [PDF]

open access: yesPLoS ONE, 2013
The hypothesis that variability in natural habitats promotes modular organization is widely accepted for cellular networks. However, results of some data analyses and theoretical studies have begun to cast doubt on the impact of habitat variability on ...

Quasispecies Theory for Horizontal Gene Transfer and Recombination [PDF]

open access: yes, 2008
We introduce a generalization of the parallel, or Crow-Kimura, and Eigen models of molecular evolution to represent the exchange of genetic information between individuals in a population. We study the effect of different schemes of genetic recombination on the steady-state mean fitness and distribution of individuals in the population, through an ...

Horizontal Gene Transfer in Thermus spp.

open access: yesCurrent Issues in Molecular Biology, 2018
The small amount of genetic content in thermophiles generally limits their adaptability to environmental changes. In Thermus spp., very active horizontal gene transfer (HGT) mechanisms allow the rapid spread of strain-specific adaptive gene modules among the entire population.
