A Simple Screen to Identify Promoters Conferring High Levels of Phenotypic Noise
Figure 2
Histograms of GFP expression from clones exhibiting the highest level of noise in each population.
Clones from each of the ten populations were ranked according to the amount of noise in GFP expression produced. A histogram of GFP expression was plotted for a single clone from each population with the highest level of noise. Clones from selected populations (red, orange, and yellow lines) show a much higher level of noise than the control those from control populations (blue lines). Clones containing the fliC promoter are orange and a clone containing the flgK promoter is yellow.
