Artificial sweeteners stimulate horizontal transfer of extracellular antibiotic resistance genes through natural transformation. [PDF]
ISME J, 2022 Antimicrobial resistance has emerged as a global threat to human health. Natural transformation is an important pathway for horizontal gene transfer, which facilitates the dissemination of antibiotic resistance genes (ARGs) among bacteria. Although it is

Prophage-Dependent Neighbor Predation Fosters Horizontal Gene Transfer by Natural Transformation
mSphere, 2020 Natural transformation is a broadly conserved mechanism of horizontal gene transfer (HGT) in bacteria that can shape their evolution through the acquisition of genes that promote virulence, antibiotic resistance, and other traits.

The molecular diversity of transcriptional factor TfoX is a determinant in natural transformation in Glaesserella parasuis [PDF]
Frontiers in Microbiology, 2022 Natural transformation is a mechanism by which a particular bacterial species takes up foreign DNA and integrates it into its genome. The swine pathogen Glaesserella parasuis (G. parasuis) is a naturally transformable bacterium.

Native Plasmid-Encoded Mercury Resistance Genes Are Functional and Demonstrate Natural Transformation in Environmental Bacterial Isolates [PDF]
mSystems, 2019 Plasmid-mediated horizontal gene transfer (HGT) is a major driver of genetic diversity in bacteria. We experimentally validated the function of a putative mercury resistance operon present on an abundant 8-kbp native plasmid found in groundwater samples ...

Homotopy of Natural Transformations [PDF]
Canadian Journal of Mathematics, 1970 Let C be a full subcategory of T, the category of based topological spaces and based maps, and let Cn be the corresponding category of n-tuples. Let S, T: Tn → T be covariant functors which respect homotopy classes and let u, v: S → T be natural transformations, u and v are homotopic inC, denoted u ≃ v(C), if uX ≃ vX: SX → TX (X ∈ Cn), that is to say ...

An Improved Natural Transformation Protocol for the Cyanobacterium Synechocystis sp. PCC 6803
Frontiers in Plant Science, 2020 The naturally transformable cyanobacterium Synechocystis sp. PCC 6803 is a widely used chassis strain for the photosynthetic production of chemicals. However, Synechocystis possesses multiple genome copies per cell which means that segregating mutations ...
