## Abstract 17 spontaneous Gal^β^ mutants of __S. coelicolor__ were studied using Southern blottings, but no insertion or deletion mutations were found. 10 mutants of __S. lividans__ included three deletion mutations. The reasons for the lack of insertion mutants are discussed.
A mutant of Streptomyces coelicolor A 3(2) highly resistant to chloramphenicol was selected. It had amplified some chromosomal DNA fragments to a copy number of 20-50. Some of the amplified fragments were cloned and used as hybridisation probes to investigate the spontaneous chloramphenicol-sensitiv
