WebNov 8, 2024 · The pDawn and pDusk system demonstrated potential modularity of light sensors in synthetic biology. The YF1/FixJ system is inactivated by blue light, thereby leading to the pDawn system. To achieve blue light activated gene expression, the lamda repressor cI was used as an inverter (Ohlendorf et al., 2012). WebpsfGFP-pDawn-Tn7 in darkness was as low as that of the wild type, which demonstrates the low background activity of the pDawn-Tn7 system in P. aeruginosa. Compared with dark-treated bacteria, an approximately 20-fold increase in sfGFP expression from PAO1 psfGFP-pDawn-Tn7 under blue light illumination suggested that our modified light …
