Fig. 2From: Genetic characterization of novel class 1 Integrons In0, In1069 and In1287 to In1290, and the inference of In1069-associated integron evolution in Enterobacteriaceae Genetic structures and proposed evolutionary history of In1069 and related integrons. Genes are denoted by arrows and colored according to gene function classification. Shaded areas denote regions of homology (>95% nucleotide identity). Double-headed arrows indicate the addition or excision of relevant gene cassttes. Asterisks denote the partially sequenced coding regions of relevant genesBack to article page
