Nearly two decades ago, I started some genetic as well as genomic study using a eubacterium, Bacillus subtilis 168. Her ability drew my great attention, to take up DNA given outside and integrate it into her genome via homologous recombination. This research style later lead to development of a novel cloning vector. Most DNA cloning vectors can not handle a large number of genes, equivalent to giant DNA, at one time. Several works merged to provide the novel cloning system based on the B. subtilis genome as a cloning vehicle. The Bacillus GenoMe (BGM) vector derived from the 4.2-Mb genome of B. subtilsi168 was demonstrated to accommodate fairly large DNAs and is highlighted by the successful stable cloning of a whole
3.5-Mb genome of the nonpathogenic, unicellular photosynthetic bacterium Synechocystis (1) and any sequence-known DNA (2-3). Attempts to build a man-made synthetic genome will also be introduced.
