Abstract. Although bacterial species display wide variation in their overall GC contents, the genes within a particular species' genome are relatively similar in base composition. As a result, sequences that are novel to a bacterial genome—i.e., DNA introduced through recent horizontal transfer—often bear unusual sequence characteristics and can be distinguished from ancestral DNA. At the time of introgression, horizontally transferred genes reflect the base composition of the donor genome; but… 
A quantitative account of genomic island acquisitions in prokaryotes
TLDR
It is suggested that many of the resident Genomic Islands per prokaryotic genome originated from the same source, which may have implications with respect to their regulatory interactions, and for the elucidation of the common origins of these acquired gene clusters.
Impact of Horizontal Genetic Transfer on the Evolution of Bacterial Genomes
TLDR
If the roles of horizontal genetic transfer and chromosomal deletion are considered in shaping the composition of bacterial chromosomes, it can be seen that the mode of genome evolution has strong implications for how bacteria diversify.
The Dynamic Bacterial Genome
TLDR
Directional mutation pressures provide a distinct ‘‘fingerprint’’ to a bacterial genome owing to the differential mutational proclivities of DNA polymerases, the nature of mismatch correction systems, the numbers and abundances of tRNA species, and even relative concentrations of precursor nucleotide pools.
The source of laterally transferred genes in bacterial genomes
TLDR
It is shown that contrary to what is often supposed, these genes fit the description of recently described genes in lambdoid phages, named 'morons', and should not be cited as evidence for genetic exchange between distantly related bacteria.
Horizontal Gene Transfer Building Prokaryote Genomes: Genes Related to Exchange Between Cell and Environment are Frequently Transferred
TLDR
A method for the detection of genes that potentially originated by HGT is developed based on the comparison of BLAST scores between homologous genes to 16S rRNA-based phylogenetic distances between the involved organisms, which confirms that genes related to protein translation are vertically inherited, whereas interestingly, transport and binding proteins are strongly enriched among HGT genes.
The genomic architecture of introgression among sibling species of bacteria
TLDR
Introgression among these closely-related species has been very limited, confined to the symbiosis plasmids and a few chromosomal islands, implying that introgression occurred by conjugative plasmid transfer.
Association between translation efficiency and horizontal gene transfer within microbial communities
TLDR
Analysis of genomic sequences of more than 190 microorganisms and the HGT events that have occurred between them shows that the number of genes that were horizontally transferred between organisms is positively correlated with the similarity between their tRNA pools, and suggests that frequent HGT may be a homogenizing force that increases the similarity in the t RNA pools of organisms within the same community.
How microbiology helps define the rhizome of life
TLDR
It is confirmed that the term “rhizome” in evolutionary biology applies to the entire cellular life history, and this view of evolution should resemble a clump of roots representing the multiple origins of the repertoires of the genes of each species.
Ancestral genome estimation reveals the history of ecological diversification in Agrobacterium
TLDR
This work used a phylogenetic approach accounting for the transfer of genes (or groups of genes) to estimate the history of genomes in Agrobacterium biovar 1, a diverse group of soil and plant-dwelling bacterial species, and identified clade-specific blocks of co-transferred genes encoding coherent biochemical pathways that may have contributed to the evolutionary success of key Agrobacteria clades.
Phylogeny vs genome reshuffling: horizontal gene transfer
TLDR
In the post-genomic era, the explosion of known sequences through large-scale sequencing projects has unraveled the weakness of traditional 16S rDNA gene tree based evolutionary model and generated greater genetic diversity, which is likely to increase resource use and ecosystem resilience.

Selfish operons: horizontal transfer may drive the evolution of gene clusters.
TLDR
A model is presented whereby the formation of gene clusters in bacteria is mediated by transfer of DNA within and among taxa, and predicts a mosaic structure of modern genomes in which ancestral chromosomal material is interspersed with novel, horizontally transferred operons providing peripheral metabolic functions.

TLDR
Three clonal frames are described on the basis of the present local high-resolution data, as well as previous analyses of restriction fragment length polymorphism (RFLP) and of multilocus enzyme electrophoresis (MLEE) covering small regions more widely dispersed on the chromosome.
Lateral transfer in natural populations of eukaryotes.
TLDR
The importance of lateral transfers for host organisms must await answers to more general questions about the long-term evolutionary significance of mobile elements and the extent to which they can act as vectors for host genomic sequences.

TLDR
Analysis of DNA sequence has revealed that practically all organisms are subject to directional mutation pressure, and the theory offers plausible explanations for the large heterogeneity in guanine-plus-cytosine content among different parts of the vertebrate genome.
Heterogeneity of genome sizes among natural isolates of Escherichia coli
TLDR
Comparisons of the genetic maps of Escherichia coli K-12 and Salmonella typhimurium LT2 suggest that the size and organization of bacterial chromosomes are highly conserved, and the genomes of natural isolates are larger than those of laboratory strains, largely because of the fact that laboratory strains were derived from the subgroup of E. coli with the smallest genomes.
Detecting selective sweeps in naturally occurring Escherichia coli.
TLDR
Evidence that some evolutionary event has recently purged the variability in the region surrounding the gapA and pabB loci in E. coli can be explained by the spread of a selected allele through the global E. Escherichia coli population by directional selection and the resulting loss in variability inThe surrounding regions due to genetic hitchhiking.
Clonal divergence in Escherichia coli as a result of recombination, not mutation.
TLDR
Recombination has been the dominant force driving the clonal divergence of the ECOR group A strains and must be considered a significant factor in structuring E. coli populations.

Acquisition of the inv/spa genes may have been a key event in the evolution of the salmonellae as pathogens, following which the invention of flagellar phase shifting facilitated niche expansion to include warm-blooded vertebrates.
