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.
摘要
丝状细菌天蓝色链霉菌的染色体是线性的，但遗传图谱是环状的。我们基于荧光原位杂交技术提供了细胞学证据，表明染色体末端经常共定位，这与染色体末端结合在一起从而有效形成环状染色体的观点一致。这些观察结果为线性细菌染色体如何呈现环状遗传图谱提供了一种可能的解释。
