The Q-PCR verification of the enhanced promoters and the impacts of the artificial sequences combined with other natural promoters. a The relative changing fold of crtY transcription in the selected four champion strains (LE7-Y1, LG7-Y1, HE1-O1, HG3-O1) compared with their corresponding control strain were verified by Q-PCR. b The artificial sequences in the four champion strains were added to other promoters and the impacts on promoters’ strengths were detected in the form of relative fluorescence of GFP
