Optimizing Transformation Frequency of Cryptococcus neoformans and Cryptococcus gattii Using Agrobacterium tumefaciens

Journal of Fungi, 2021
The transformation of Cryptococcus spp. by Agrobacterium tumefaciens has proven to be a useful genetic tool. A number of factors affect transformation frequency. These factors include acetosyringone concentration, bacterial cell to yeast cell ratio, cell

Disinfectants facilitate the transformation of exogenous antibiotic resistance genes via multiple pathways

Ecotoxicology and Environmental Safety, 2023
The prevalence and spread of multidrug-resistant (MDR) bacteria pose a global challenge to public health. Natural transformation is one of the essential ways for horizontal transfer of antibiotic resistance genes (ARGs).

Optimization of the Transformation Protocol for Increased Efficiency of Genetic Transformation in Hevea brasiliensis

Plants, 2022
The recurring growth of bacterium in newly developed resistant cells and a minimal level of bacterial infection rate are the main limiting factors of Agrobacterium-mediated transformation experiments in Hevea brasiliensis.

Impacts of deforestation and forest regeneration on soil bacterial communities associated with phosphorus transformation processes in the Brazilian Amazon region

Ecological Indicators, 2023
Land-use change has negative impacts on the biodiversity of plants and animals. However, we lack studies and/or information about the impacts of land-use change on the biodiversity of soil microorganisms, especially those involved in the phosphorus (P ...

Bacterial Transformation Buffers Environmental Fluctuations through the Reversible Integration of Mobile Genetic Elements

mBio, 2020
Horizontal gene transfer (HGT) promotes the spread of genes within bacterial communities. Among the HGT mechanisms, natural transformation stands out as being encoded by the bacterial core genome.

Integrated FT-ICR MS and metabolome reveals diatom-derived organic matter by bacterial transformation under warming and acidification

iScience, 2023
Summary: Bacterial transformation and processing of diatom-derived organic matter (OM) is extremely important for the cycling of production and energy in marine ecosystems; this process contributes to the production of microbial food webs. In this study,

Mechanisms of Transforming DNA Uptake to the Periplasm of Bacillus subtilis

mBio, 2021
Transformation is a widely distributed mechanism of bacterial horizontal gene transfer that plays a role in the spread of antibiotic resistance and virulence genes and more generally in evolution.

BACTERIAL TRANSFORMATION REACTIONS [PDF]

Bacteriological Reviews, 1952
This article by Austrian reviewed the research conducted on bacterial transformation since Avery, MacLeod, and McCarty's 1944 article. Austrian briefly worked on transformation with MacLeod at New York University after MacLeod left Avery's lab in 1941.

Bacterial transformation v1 [PDF]

, 2019
Transformation of competent Escherichia coli cultures with heterologous DNA. This protocol allows the introduction of external DNA into competent E. coli cells. Typically, the piece of DNA consists of a plasmid, either for its cloning or for heterologous protein expression.
