Comparative Genomics in Molecular Evolution of Bacteria

Placing genomes into an evolutionary framework has proved to be usefol for deciphering the genome sequences of organisms.Comparative genomies,as a routine toolkit.has substantially incteased the understanding of the processes by which bacterial genomes evolve and led to a re-evaluation of the history of life.In this review,we present some of the most important recent advances and promising leads in the field of bacterial evolutionary genomics. Key words: Comparative genomics; HGT; Phylogeny
