Genome analyses of three strains of Rhodobacter sphaeroides: evidence of rapid evolution of chromosome II.

ABSTRACT: Three strains of Rhodobacter sphaeroides of diverse origin have been under investigation in our laboratory for their genome complexities, including the presence of multiple chromosomes and the distribution of essential genes within their genomes. The genome of R. sphaeroides 2.4.1 has been completely sequenced and fully annotated, and now two additional strains (ATCC 17019 and ATCC 17025) of R. sphaeroides have been sequenced. Thus, genome comparisons have become a useful approach in determining the evolutionary relationships among different strains of R. sphaeroides. In this study, the concatenated chromosomal sequences from the three strains of R. sphaeroides were aligned, using Mauve, to examine the extent of shared DNA regions and the degree of relatedness among their chromosome-specif
