Microbial genomes: dealing with diversity.

abstract：:Toxin-antitoxin (TA) systems are small genetic modules that are abundant in bacterial genomes. Three types have been described so far, depending on the nature and mode of action of the antitoxin component. While type II systems are surprisingly highly represented because of their capacity to move by horizontal gene tr...
