Abstract
The present invention relates to a novel sporulation gene isolated from B. thuringiensis, and a DNA segment comprising the nucleic acid sequences encoding the gene and DNA sequences encoding crystal toxin proteins wherein said DNA segment is stably integrated into a B. thuringiensis host by homologous recombination. The invention further relates to a DNA segment wherein the sporulation gene is mutated thereby rendering an oligosporogenic or asporogenic transformed B. thuringiensis as a result of stable integration of the DNA segment into the Bacillus thuringiensis chromosome by homologous recombination.
