Evolution of the terminal regions of the Streptomyces linear chromosome.
Comparative analysis of the Streptomyces chromosome sequences, between Streptomyces coelicolor, Streptomyces avermitilis, and Streptomyces ambofaciens ATCC23877 (whose partial sequence is released in this study), revealed a highly compartmentalized genetic organization of their genome. Indeed, despite the presence of specific genomic islands, the central part of the chromosome appears highly sy...
متن کاملPhysical map of the linear chromosome of Streptomyces griseus.
The chromosomal DNA of Streptomyces griseus 2247 (a derivative of strain IFO3237) was digested with several restriction endonucleases and analyzed by pulsed-field gel electrophoresis (PFGE). Digestion with AseI and DraI gave 15 and 9 fragments, respectively, the total sizes of which were 7.8 Mb. All the AseI and DraI fragments were aligned on a linear chromosome map by using linking plasmids an...

15 صفحه اولIdentification of genes with fast-evolving regions in microbial genomes.
Complete sequences of multiple strains of the same microbial species provide an invaluable source for studying the evolutionary dynamics between orthologous genes over a relatively short time scale. Usually the intensity of the selection pressure is inferred from a comparison between the nonsynonymous substitution rate and the synonymous substitution rate. In this paper, we propose an alternati...
متن کاملUnderreplicated Regions in Drosophila melanogaster Are Enriched with Fast-Evolving Genes and Highly Conserved Noncoding Sequences
Many late replicating regions are underreplicated in polytene chromosomes of Drosophila melanogaster. These regions contain silenced chromatin and overlap long syntenic blocks of conserved gene order in drosophilids. In this report we show that in D. melanogaster the underreplicated regions are enriched with fast-evolving genes lacking homologs in distant species such as mosquito or human, indi...
