fused genes and their use for the presence of metals or xenobiotic compounds.

摘要

The invention relates to a fused gene containing: the promoter sequence of UN / OS GEN / S CODING / N RESISTANCE one or more metals or encoding the catabolism ONE OR MORE xenobiotics, said PROMOTER stimulable IN THE PRESENCE OF SAID / S METAL / ES, COMPOSITE / S xenobiotic / SO FOR BOTH, AND DESCENDING THE PROMOTER, a gene that produces a detectable signal, such as light emitted by GEN being this gene under the control of said promoter; This gene produces a detectable signal, which is situated in such a position, that induction of promoter causes transcription of the gene PRODUCING A detectable signal AND SO THAT NO LIMIT OF ILLUMINATION between the promoter and the gene that produces the detectable signal .
