FIG 5.
Analysis of cross correlations between the transcription of promoters with high NTRs. (a to d) Representative expression patterns of dual-color reporters with SfGFP and CyOFP1 expression, respectively, driven by two high-NTR promoters. (a) Negative correlation between the transcription of flp and PA5127 promoters. (b and c) Expression of flp/mdcA and pqsA/fliC reporters is distributed in relatively concentrated areas. (d) Linear positive correlation between the transcription of pvdA and pvdS promoters. (e) Cross-extrinsic noise index (κ) of dual-color cross reporters. κ is the mean value of κp1,p2 and κp2,p1. Two promoters in mutual reporters with κ > 0.25 or κ < −0.25 were connected with red (κ > 0.25) or blue (κ < −0.25) line. Shade of red or blue lines indicates the κ value according to the color bar. Background colors of promoters represents different functional categories to which they belong.
