Precise targeted integration by a chimaeric transposase zinc-finger fusion protein [PDF]

open access: yes, 2010
Transposons of the Tc1/mariner family have been used to integrate foreign DNA stably into the genome of a large variety of different cell types and organisms.

PSOSP uncovers pervasive SOS‐independent prophages with distinct genomic and host traits in bacterial genomes

open access: yesiMeta, Volume 4, Issue 5, October 2025.
Prophages are ubiquitously present in bacterial genomes, significantly influencing host physiological and ecological functions. We present Prophage SOS‐dependency Predictor (PSOSP), a novel bioinformatics tool that predicts prophages induction modes by analyzing the Heterology Index (HI) of LexA protein binding to target DNA, classifying prophages into

Analysis of the SOS response of Vibrio and other bacteria with multiple chromosomes [PDF]

open access: yes, 2012
Background: The SOS response is a well-known regulatory network present in most bacteria and aimed at addressing DNA damage. It has also been linked extensively to stress-induced mutagenesis, virulence and the emergence and dissemination of antibiotic ...

"Activated"-RecA protein affinity chromatography of LexA repressor and other SOS-regulated proteins. [PDF]

open access: greenProceedings of the National Academy of Sciences, 1989
We have developed an affinity column to study the interaction of LexA repressor and other substrates with the activated form of RecA protein. Nucleoprotein complexes of RecA protein, (dT)25-30, and adenosine 5'-[gamma-S]thio-triphosphate were formed in solution and bound to RecA protein-agarose columns.

Transcription factors ERF74/77/108/125 enhance thermotolerance in rice by regulating common and distinct heat‐responsive gene expression

open access: yesPlant Biotechnology Journal, Volume 23, Issue 10, Page 4539-4551, October 2025.
Summary Heat stress severely impacts crop productivity, necessitating the identification of key regulatory genes for improving thermotolerance. Here, we demonstrate that the rice nuclear‐localized AP2/ERF transcription factors ERF74/77/108/125 function as critical regulators of heat stress responses.

Factors determining chromosomal localization of transposable elements in plants

open access: yesPlant Biology, Volume 27, Issue 6, Page 975-989, October 2025.
We review transposon chromosomal niches, and the functional consequences of their specific chromosomal localization in plants. Abstract Transposable elements (TEs) constitute a significant part of plant genomes and shape their genomic landscape. While some TEs are ubiquitously dispersed, other elements specifically occupy discrete genomic loci.

Detection Of DNA Damage By Use Of Escherichia Coli Carrying recA\u27::lux, uvrA\u27::lux, And alkA\u27::lux Reporter Plasmids [PDF]

open access: yes, 1997
Plasmids were constructed in which DNA damage-inducible promoters recA, uvrA, and alkA from Escherichia coli were fused to the Vibrio fischeri luxCDABE operon. Introduction of these plasmids into E. coli allowed the detection of a dose-dependent response

HilE regulates HilD by blocking DNA binding in Salmonella enterica serovar Typhimurium [PDF]

open access: yes, 2018
The Salmonella type three secretion system (T3SS), encoded in the Salmonella pathogenicity island 1 (SPI1) locus, mediates the invasion of the host intestinal epithelium.

Adaptive Tolerance of Listeria monocytogenes to Chemical Oxidants: Comparative Analysis of Transcriptomic Studies

open access: yesComprehensive Reviews in Food Science and Food Safety, Volume 24, Issue 5, September 2025.
ABSTRACT Listeria monocytogenes is a foodborne pathogen that poses significant challenges to food safety and public health due to its ability to adapt to harsh environments, particularly those found in food processing facilities. This review explores the global transcriptional responses of L.

Cholinergic and Glutamatergic Axons Differentially Require Glial Support in the Drosophila PNS

open access: yesGlia, Volume 73, Issue 7, Page 1365-1382, July 2025.
Main Points In the Drosophila PNS, motor‐ and sensory axons differentially interact with wrapping glia processes. Sensory axons are more weakly associated with wrapping glia and show a length dependent degeneration upon loss of wrapping glia. ABSTRACT In vertebrates, there is a differential interaction between peripheral axons and their associated ...
