Site Streptomyces ambofaciens - Partial sequencing of the linear chromosome Description Bacteria of the genus Streptomyces are characterized by a complex morphologic differentiation cycle accompanied by the production of numerous extracellular enzymes as well as secondary metabolites. These bacteria present a phenomenon of genetic instability resulting from telomeric instability.
Genomic rearrangements define a large region which is non-essential under laboratory conditions.
Furthermore, analysis of genomic rearrangements and of intra- and interspecific polymorphisms in these regions suggests that exchanges of genetic information are frequent in these areas. On the other hand, the more internal regions of the chromosome are characterized by a higher level of genetic conservation. The Streptomyces web page.
