Comparative Genomics: Genome Configuration and the Driving Forces in the Evolution of Vibrios

摘要: This chapter outlines recent progress in the study of Vibrio genomes, including information from genome sequences covered to date. A Japanese group and an American independently reported possession two circular chromosomes for vibrios. First, all vibrios examined possessed chromosomes: no with only one chromosome were found. Second, size large was relatively constant among The distribution genes known function between small provides tantalizing clues about how two-chromosome configuration Vibrionaceae might confer evolutionary advantage. Thus, whatever origin vibrios, stable maintenance genomes multiple have required evolution shared mechanisms control replication. Genome sequencing three species enabled authors precisely compare structures strains. a brief introduction some topics on horizontal gene transfer mainly relation acquisition pathogenicity. Recently, it that chromosomal superintegrons be genetic source resistance clinically relevant antibiotics through integron-mediated recombination events. As parahaemolyticus, further comparative analysis more should give us exciting new knowledge exhibiting variety lifestyles.
