Methylome-dependent transformation of emm1 group A streptococci

mBio, 2023
Genetic intractability presents a fundamental barrier to the manipulation of bacteria, hindering advancements in microbiological research. Group A Streptococcus (GAS), a lethal human pathogen currently associated with an unprecedented surge of infections

Deletion of the primase-polymerases encoding gene, located in a mobile element in Thermus thermophilus HB27, leads to loss of function mutation of addAB genes

Frontiers in Microbiology, 2022
DNA primase-polymerases (Ppol) have been shown to play active roles in DNA repair and damage tolerance, both in prokaryotes and eukaryotes. The ancestral thermophilic bacterium Thermus thermophilus strain HB27 encodes a Ppol protein among the genes ...

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).

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.

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.
