| Abstract: | The genes of Photobacterium leiognathi luminescence system were cloned in plasmid pUC18. Escherichia coli cells harboring a recombinant plasmid pPHL1 are luminescent. pPHL1 contains luciferase genes and genes responsible for aldehyde biosynthesis. The luminescence of Escherichia coli is subject to autoinductor regulation similar to the one existing in luminescent bacteria. The 2.7 kb fragment of Photobacterium leiognathi DNA containing the genes for alpha- and beta-luciferase subunits were cloned in pUC19. |
