(a) Evenness value (θE) scatter diagram, with average and SD of log hybridization signal ratio. (b) θE values by genome fragment, ID 1 to 92, 93 to 182, 183 to 278, and 279 to 338 originated from P. fluorescens ATCC 13525T, P. chlororaphis ATCC 9447, P. putida ATCC 12633T, and P. aeruginosa ATCC 15692, respectively. The solid line and dotted lines (horizontal) indicate average and SD, respectively.
