| Abstract |
The Streptomyces glaucescens genome frequently undergoes gross genomic rearrangement events which result in the deletion of extremely large segments of chromosomal DNA. The structure and origin of the DNA forming the novel junctions arising from five of these deletion events are described. Only one junction proved to be the result of a relatively simple event; the remainder were more complex, with one involving DNA which originated from at least five distinct loci. In three of the investigated cases, DNA sequences present in the junctions appeared to have resulted from the duplication of previously unique sequences, suggesting that duplication of chromosomal segments may be an important factor in genetic instability. The nucleotide sequences surrounding these junctions and their respective wild-type termini were determined. |
