<p>Gene expression systems comprising an expression vector and a <<trans-acting DNA segment>>, where the expression vector comprises the gene or genes to be expressed and one or more cis-acting regulatory elements which are responsive to a trans-acting factor produced by said <<trans-acting DNA segment>>. More specifically the invention relates to such gene expression systems where said <<trans-acting DNA segment>> and said cis-acting regulatory elements comprise one or more segments of the genome from a Bacillus species. Methods for stimulating the production of gene products, vectors for transforming microorganisms, and their use are also disclosed.</p> |
