Populus PtrbHLH011 Is a Transcriptional Co-Regulator Involved in the Activation of Cell Wall Biosynthesis by Iron Deprivation. [PDF]

Plant Biotechnol J
ABSTRACT The lack of a mechanistic understanding of the environmental plasticity of secondary cell wall (SCW) biosynthesis restricts large‐scale biomass and bioenergy production on marginal lands. Using Populus (poplar), a key bioenergy crop, we discovered that iron deprivation, a prevalent abiotic stress on marginal lands, stimulates SCW biosynthesis ...

RecA and Specialized Error-Prone DNA Polymerases Are Not Required for Mutagenesis and Antibiotic Resistance Induced by Fluoroquinolones in Pseudomonas aeruginosa

Antibiotics, 2022
To cope with stressful conditions, including antibiotic exposure, bacteria activate the SOS response, a pathway that induces error-prone DNA repair and mutagenesis mechanisms.

Bacteriophage 434 Hex Protein Prevents RecA-Mediated Repressor Autocleavage

Viruses, 2013
In a λimm434 lysogen, two proteins are expressed from the integrated prophage. Both are encoded by the same mRNA whose transcription initiates at the PRM promoter. One protein is the 434 repressor, needed for the establishment and maintenance of

Redesign of ultrasensitive and robust RecA gene circuit to sense DNA damage

Microbial Biotechnology, 2021
Summary SOS box of the recA promoter, PVRecA from Vibrio natriegens was characterized, cloned and expressed in a probiotic strain E. coli Nissle 1917. This promoter was then rationally engineered according to predicted interactions between LexA repressor

The trans-activation domain of the sporulation response regulator Spo0A revealed by X-ray crystallography [PDF]

, 2000
Sporulation in Bacillus involves the induction of scores of genes in a temporally and spatially co-ordinated programme of cell development. Its initiation is under the control of an expanded two-component signal transduction system termed a phosphorelay.

Transcriptional analysis of the recA gene of Streptococcus thermophilus

Microbial Cell Factories, 2006
Background RecA is a highly conserved prokaryotic protein that not only plays several important roles connected to DNA metabolism but also affects the cell response to various stress conditions.

Regulation of transcription elongation in response to osmostress [PDF]

, 1967
Cells trigger massive changes in gene expression upon environmental fluctuations. The Hog1 stress-activated protein kinase (SAPK) is an important regulator of the transcriptional activation program that maximizes cell fitness when yeast cells are exposed

Biochemical characterization of Borrelia burgdorferi's RecA protein. [PDF]

PLoS ONE, 2017
RecA plays key roles in DNA recombination, replication and repair. Mutation of recA in the Lyme disease spirochete, Borrelia burgdorferi, fails to produce some of the phenotypes expected from study of recA mutation in other organisms.

The Sulfolobus solfataricus radA paralogue sso0777 is DNA damage inducible and positively regulated by the Sta1 protein [PDF]

, 2007
Little is known about the regulation of the DNA damage-mediated gene expression in archaea. Here we report that the addition of actinomycin D to Sulfolobus solfataricus cultures triggers the expression of the radA paralogue sso0777.
