Method for regulating transcription of foreign genes
First Claim
1. An isolated promoter for promoting transcription of a foreign gene in transgenic organisms, which comprises a nitrogen-inducible promoter with or without cis-acting sequence for expression of said gene and adapted to be modulated for transcriptional expression of said gene by addition or removal of a nitrogen inducer, said isolated promoter having the nucleic acid sequence as depicted in SEQ ID NO:

Abstract
The present invention relates to a method of regulating the transcription of transgene in genetically-modified organisms. More specifically, the invention relates to the use of expression vectors harboring the coding sequence of a gene of interest under the transcriptional control of promoting sequences for which activity is regulated by the presence of nitrogen.
