The outermost circle indicates the chromosomal location in base pairs (each
tick is 100 kb). The distribution of genes is depicted by coloured boxes according
to functional category and direction of transcription (outer band is the plus
strand; inner band is the minus strand). Red arrows, the locations and direction
of transcription of ribosomal RNA genes; green arrow, the inverted region
that resulted from a homologous recombination event between rrnA and
rrnB; blue arrows, location of two regions containing probable bacteriophages.
The black plot in the centre is percentage G+C content plotted as the average
for non-overlapping 1-kb windows spanning one strand for the entire P.
aeruginosa genome. Yellow bars, regions of 
3.0 kb with
G+C content of two standard deviations (< 58.8%) below the mean
(66.6%) (see Supplementary Information). A linear map
of the genes, with the colour code for functional categories, is available
at http://www.pseudomonas.com.
