Abstract
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.
