Gene duplications in the E. coli genome: common themes among pathotypes

Gene duplication underlies a significant proportion of gene functional diversity and genome complexity in both eukaryotes and prokaryotes. Although several reports in the literature described the duplication of specific genes in E. coli, a detailed analysis of the extent of gene duplications in this microorganism is needed.The genomes of the E. coli enteroaggregative strain 042 and other pathogenic strains contain duplications of the gene that...
