Two components of DNA replication-dependent LexA cleavage

open access: yesJournal of Biological Chemistry, 2020
Induction of the SOS response, a cellular system triggered by DNA damage in bacteria, depends on DNA replication for the generation of the SOS signal, ssDNA.

Evaluation of phylogenetic footprint discovery for predicting bacterial cis-regulatory elements and revealing their evolution

open access: yesBMC Bioinformatics, 2008
Background The detection of conserved motifs in promoters of orthologous genes (phylogenetic footprints) has become a common strategy to predict cis-acting regulatory elements.

The SOS response of Listeria monocytogenes is involved in stress resistance and mutagenesis [PDF]

open access: yes
The SOS response is a conserved pathway that is activated under certain stress conditions and is regulated by the repressor LexA and the activator RecA.

Factors determining chromosomal localization of transposable elements in plants

open access: yesPlant Biology, EarlyView.
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.

Gene expression noise in a complex artificial toxin expression system.

open access: yesPLoS ONE, 2020
Gene expression is an intrinsically stochastic process. Fluctuations in transcription and translation lead to cell-to-cell variations in mRNA and protein levels affecting cellular function and cell fate. Here, using fluorescence time-lapse microscopy, we

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 ...

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

Interaction of LexA repressor with the asymmetric dinG operator and complete nucleotide sequence of the gene [PDF]

open access: yesJournal of Bacteriology, 1992
The dinG gene was originally isolated during a search for Escherichia coli promoters which are components of the SOS regulon. The regulatory region of this gene contains a potential binding site for LexA repressor which is quite different from other known sites.

The pea branching RMS2 gene encodes the PsAFB4/5 auxin receptor and is involved in an auxin-strigolactone regulation loop [PDF]

open access: yes, 2017
Strigolactones (SLs) are well known for their role in repressing shoot branching. In pea, increased transcript levels of SL biosynthesis genes are observed in stems of highly branched SL deficient (ramosus1 (rms1) and rms5) and SL response (rms3 and rms4)
