Abstract We constructed integrative plasmids to place xylA-lacZ indicator gene fusions into two different loci of the Bacillus megaterium chromosome, gdh2 and trpC, in lac mutants of strains DSM 319 and QM B1551, which differ markedly. Single-crossover integration was achieved in all cases while double crossovers occurred only in gdh2 of DSM 319 and QM B1551 and in trpC of QM B1551. Neither of the loci affected regulation of the xylA-lacZ fusions. These results confirm the suitability of the two gene loci for single-copy cloning.
