op·er·on

 (ŏp′ə-rŏn′)
n.
A unit of genetic material that functions in a coordinated manner by means of an operator, a promoter, and one or more structural genes that are transcribed together.

(Genetics) genetics a group of adjacent genes in bacteria functioning as a unit, consisting of structural genes and an operator
[C20: from operate]

op•er•on

(ˈɒp əˌrɒn)

n.
a set of two or more adjacent cistrons whose transcription is under the coordinated control of a promoter, an operator, and a regulator gene.
[< French opéron (1960), derivative of opérer to work]

It was interesting to mention that the existence of dual operons regulating biosynthesis of phenazine makes this bacterium more flexibility in modulating the number of phenazine compounds.
cloacae) are highly adept at acquiring resistance genes to all disinfectants, heavy metals, and antibiotics through horizontal gene transfer between different bacteria within the environment; such genes include extended-spectrum beta-lactamases (ESBLs), copper and arsenic resistance systems (the pco and ars operons), and enzymes that hydrolyze cephalosporins (AmpC enzymes) [7,8].

proposed the use of bacterial clustered regularly interspaced short palindromic repeat (CRISPR) pathway elements to engineer specific posttranscriptional cleavage of multigene operons to yield predictable expression of the individual genes, also when placed in different positions [124].
If the possibility of HGT is excluded in experimental populations, the origin of all adaptive mutations must be through alterations to the ancestral bacterial genome (chromosome and accompanying plasmids) and might range from small-scale sequence changes affecting a single gene to larger rearrangements including deletions or duplications of whole operons or considerable portions of the genome.
One short-cut approach for the identification of the promoters, genes and operons under the direct control of a test transcription factor is to determine the binding sites of the test transcription factor on the genome.
(31) used microarrays to determine the operons derepressed by both Fur mutations and iron starvation, suggesting the presence of various iron uptake pathways.
