Role of vapBC toxin–antitoxin loci in the thermal stress response of Sulfolobus solfataricus
TA (toxin–antitoxin) loci are ubiquitous in prokaryotic microorganisms, including archaea, yet their physiological function is largely unknown. For example, preliminary reports have suggested that TA loci are microbial stress-response elements, although ...

Toxin–antitoxin (TA) loci are common in archaea and prokaryotes and allow cells to rapidly adapt to changing environmental conditions through release of active regulators of metabolism.

Genomic characterization of Microbacterium meiriae sp. nov., a novel bacterium isolated from the International Space Station [PDF]
During the microbial surveillance of the International Space Station (ISS) in April 2018, four Gram-stain positive bacterial strains, designated as F6_8S_P_2BT, F6_8S_P_3A, F6_8S_P_3B and F6_8S_P_3C, belonging to the genus Microbacterium were isolated ...

Lors de la symbiose fixatrice d’azote entre la légumineuse modèle Medicago truncatula et la rhizobiacée Sinorhizobium meliloti, les bactéries, différenciées en bactéroïdes dans la nodosité, réduisent l’azote atmosphérique (N2) en ammoniac (NH3 ...

VapC toxins from Mycobacterium tuberculosis are ribonucleases that differentially inhibit growth and are neutralized by cognate VapB antitoxins. [PDF]
The chromosome of Mycobacterium tuberculosis (Mtb) encodes forty seven toxin-antitoxin modules belonging to the VapBC family. The role of these modules in the physiology of Mtb and the function(s) served by their expansion are unknown.

The endogenous Coxiella burnetii plasmid encodes a functional toxin–antitoxin system
Coxiella burnetii is an obligate intracellular bacterium and causative agent of Q fever. Here we report that the C. burnetii genome encodes 11 toxin–antitoxin systems, which is highly unusual for intracellular bacteria, and that one TA system is encoded on the large endogenous plasmid found in almost all C. burnetii isolates.

Summary Alphaproteobacteria are typically characterized by a multipartite genome organization with a chromosome, stable chromids and accessory plasmids. Extrachromosomal elements determine the lifestyle of roseobacters and their horizontal transfer was previously correlated with rapid adaptations to novel ecological niches.

Legume–rhizobium dance: an agricultural tool that could be improved?
The present review describes the mechanisms involved in the regulation of the entire legume‐rhizobium symbiotic process and the strategies and tools of bacteria for reaching the nitrogen‐fixing state inside the nodule. Also, we revised different approaches to improve the nodulation process for a better crop yield.

Transcriptional and proteolytic regulation of the toxin-antitoxin locus vapBC10 (ssr2962/slr1767) on the chromosome of Synechocystis sp. PCC 6803. [PDF]
VapBC toxin-antitoxin (TA) systems are defined by the association of a PIN-domain toxin with a DNA-binding antitoxin, and are thought to play important physiological roles in bacteria and archaea.
