Correlations among data related to promoter strengths obtained by GFP reporter, real-time RT-qPCR, and RNA-Seq. a The positive linear relationships of data obtained in S. coelicolor M1146 derivatives. b The positive linear relationships of data obtained in S. venezuelae WVR2006 derivatives. c The positive linear relationships of data obtained in S. albus J1074 derivatives. Black dots in the three-dimensional spaces indicate the overall relationship of promoter strengths reflected by different approaches. The red, green, and blue dots scattered in the three different planes indicate the relationships of promoter strengths measured by any two approaches among the three approaches. For each promoter, the data were the averages of strengths generated by three different approaches. R ² was the linear regression coefficient
