Recent progress in the understanding of the chromosomal rearrangements in Streptomyces has allowed us to envisage the possible involvement of genetic instability in the evolution of the chromosomal structure. The characterization of recombinational events in the terminal parts of the S ambofaciens chromosome, as well as the observation by other groups that linear plasmids and chromosomes are able to interact, would provide an explanation for the very high levels of polymorphism seen in the terminal inverted repeats of different strains of Streptomyces.
对链霉菌染色体重排的认识取得的最新进展,使我们能够设想遗传不稳定性可能参与了染色体结构的进化。对产二素链霉菌染色体末端重组事件的表征,以及其他研究小组观察到的线性质粒和染色体能够相互作用,这将为在不同链霉菌菌株的末端反向重复序列中观察到的非常高的多态性水平提供一种解释。
