Gene Gain and Gene Loss in Streptococcus: Is It Driven by Habitat?
30 Aug 2006
Abstract excerpt
Bacterial genomes can evolve either by gene gain, gene loss, mutating existing genes, and/or by duplication of existing genes. Recent studies have clearly demonstrated that the acquisition of new genes by lateral gene transfer (LGT) is a predominant force in bacterial evolution. To better understand the significance of LGT, we employed a comparative genomics approach to model species-specific and intraspecies...
