Colocalisation of genes regulated by AraC. a The figure shows a dual fluorescence image of strain LR31, carrying a LacO array at araBAD and a MalO array at araJ stained with Hoechst 33,258. b and c The bar charts show the distance between two distal chromosomal locations, each independently tagged with different FROS reporters. b Distance measurements between the araBAD locus, tagged with a LacO array, and the araJ locus, tagged with a MalO array, were calculated in 300 individual cells. Absolute distances between the two chromosomal locations in the presence and absence of the inducer, arabinose, are plotted. c Distance measurements between the araBAD locus, tagged with a LacO array, and the araFGH locus, tagged with a MalO array, were calculated in 300 individual cells. Absolute distances between the two chromosomal locations in the presence and absence of the inducer, arabinose, are plotted
