The coevolution of toxin and antitoxin genes drives the dynamics of bacterial addiction complexes and intragenomic conflict [PDF]
, 2012 Bacterial genomes commonly contain ‘addiction’ gene complexes that code for both a toxin and a corresponding antitoxin. As long as both genes are expressed, cells carrying the complex can remain healthy.

Communications Biology, 2020 Toxin-antitoxin (TA) systems are widespread on mobile genetic elements and in bacterial chromosomes. In type I TA, synthesis of the toxin protein is prevented by the transcription of an antitoxin RNA.

The vapB-vapC operon of Acidovorax citrulli functions as a bona-fide toxin-antitoxin module
Frontiers in Microbiology, 2016 Toxin–antitoxin systems are commonly found on plasmids and chromosomes of bacteria and archaea. These systems appear as biscystronic genes encoding a stable toxin and a labile antitoxin, which protects the cells from the toxin’s activity. Under specific,

Escherichia coli EHEC Germany outbreak preliminary functional annotation using BG7 system [PDF]
, 2011 We have annotated the European outbreak E. coli EHEC genome sequenced by BGI (6-2-2011) and assembled with MIRA by Nick Loman (6-2-2011 ). Our system BG7, Bacterial Genome annotation of Era7 Bioinformatics, predicts ORFs and annotates them based on ...

Prokaryote toxin–antitoxin modules: Complex regulation of an unclear function
Protein Science, 2021 Toxin–antitoxin (TA) modules are small operons in bacteria and archaea that encode a metabolic inhibitor (toxin) and a matching regulatory protein (antitoxin).

Regulation of toxin–antitoxin systems by proteolysis
Plasmid, 2013 Toxin-antitoxin systems are widely distributed among many bacterial species, including human pathogens. Typically, these systems consist of two genes in an operon which encodes a stable toxin disrupting essential cellular processes and a labile antitoxin preventing toxicity.

Small Open Reading Frames, Non-Coding RNAs and Repetitive Elements in Bradyrhizobium japonicum USDA 110 [PDF]
, 2016 Small open reading frames (sORFs) and genes for non-coding RNAs are poorly investigated components of most genomes. Our analysis of 1391 ORFs recently annotated in the soybean symbiont Bradyrhizobium japonicum USDA 110 revealed that 78% of them contain ...

Toxin–antitoxin systems: reversible toxicity
Current Opinion in Microbiology, 2017 Toxin-antitoxin (TA) systems encoded on the plasmids and chromosomes of bacteria are emerging as key players in stress adaptation. In particular, they have been implicated in the induction of persisters non-growing cells that can evade antibiotic exposure.

Complete Assembly of the Genome of an Acidovorax citrulli Strain Reveals a Naturally Occurring Plasmid in This Species [PDF]
, 2019 Acidovorax citrulli is the causal agent of bacterial fruit blotch (BFB), a serious threat to cucurbit crop production worldwide. Based on genetic and phenotypic properties, A.
