摘要

The development of efficient molecular cloning systems in the Gram-positive micro-organism Bacillus subtilis based on plasmid vectors derived from Staphylococcus aureus has met with several difficulties. Frequently observed problems with these plasmids were structural and segregational instability, and the low efficiencies in random cloning of foreign DNA (shotgun cloning). The latter is generally manifested in low yields of clones and limited insert sizes. The main purposes of the investigations described in the thesis were to uncover the major factors interfering with efficient molecular cloning in B. subtilis and, with this knowledge, to develop efficient and stable host-vector systems for this organism.
