Abstract
The chromosome of the filamentous bacterium Streptomyces coelicolor is linear, but the genetic map is circular. We present cytological evidence based on the use of fluorescence in situ hybridization showing that the ends of the chromosome frequently colocalize, in agreement with the idea that the ends are held together, effectively forming a circular chromosome. These observations provide a possible explanation for how a linear bacterial chromosome can exhibit a circular genetic map.Keywords
