Figure 4From: Genome-wide detection and analysis of homologous recombination among sequenced strains of Escherichia coliThe KS local random walk plot showing homologous recombination in the tryptophan (trp) operon. Genes are rectangular boxes positioned above or below the axis based on transcribed strand. KS SNDs form two non-overlapping MSCs with significant local scores exceeding 170. Both MSCs, with a combined length under 2 kb, are contained in a single 6.5 kb HSS covering most the trp operon. The positions of each KO, KC, and KS SND in E. coli K-12 are shown above the KS excursion. Random walk values below 50 are not plotted, resulting in the absence of visible KC or KO excursions.Back to article page
