Evaluation of the engineered promoters (A) and the native promoters (B and C) by the relative promoter strength in Synechocystis PCC 6803 under the respective growth condition. (A) The histogram of the relative promoter strength by comparing 22 engineered promoters to the native rnpB promoter. The original data in EYFP emission of EYFP reporter proteins per cell are from the present work. (B) The histogram of the relative promoter strength by comparing 634 native type I promoters to the native non-type-I rnpB promoter. The original data in pyrosequencing-reads of RNA transcripts are from the supplementary Table three in the work of Mitschke et al. [25]. (C) The histogram of the relative promoter strength by comparing 173 native promoters, which transcribe protein-coding genes in high level, to the native rnpB promoter. The original data in pyrosequencing-reads of RNA transcripts are from the supplementary Table five in the work of Mitschke et al. [25].
