Processes leading to the acquisition of one or more genes from a different species are reviewed for bacteria and metazoans. Evolutionary benefits related to different categories of transferred genes through acquisition and insertion mechanisms are discussed.

Horizontal Gene Transfer in Cyanobacterial Signature Genes
2009Comparison of 15 phylogenetically diverse cyanobacterial genomes identified an updated list of 183 signature genes that are widely found in cyanobacteria but absent in non-cyanobacterial species. These signature genes comprise the unique portion of the core cyanobacterial phenotype, and their absence from other lineages implies that if they arose by ...

Hosts, parasites, and horizontal gene transfer
Trends in Parasitology, 2013Mendelian inheritance transfers genes vertically within lineages, whereas horizontal gene transfer (HGT) moves genetic material between or among lineages. Herein, we explore possible mechanisms of HGT between parasites and their hosts, as their intimate contact affords substantial opportunities for HGT.

Direct Visualization of Horizontal Gene Transfer
Science, 2008Conjugation allows bacteria to acquire genes for antibiotic resistance, novel virulence attributes, and alternative metabolic pathways. Using a fluorescent protein fusion, SeqA-YFP, we have visualized this process in real time and in single cells of Escherichia coli .

Exploring the costs of horizontal gene transfer
Trends in Ecology & Evolution, 2013Horizontal gene transfer (HGT) is one of the most important evolutionary forces within microbial populations. Although evidence for beneficial fitness effects of HGT is overwhelming, recently acquired regions often function inefficiently within new genomic backgrounds so that each transfer event has the potential to disrupt existing regulatory and ...

Horizontal gene transfer not observed
Trends in Plant Science, 2000John Heritage and colleagues (University Leeds, UK) working on horizontal gene transfer, have looked for evidence that the gut bacteria from chickens had accepted and activated the bla gene (ampicillin resistance) after the birds had been fed GM maize or naked pUC18 plasmid DNA.

The record of horizontal gene transfer in Salmonella
Trends in Microbiology, 1997The evolution of virulence in Salmonella is driven by horizontal gene transfer. This has given rise to highly flexible pathogens that are able to colonize new niches and extend their host range. Tracing the record of horizontal gene transfer can provide clues to the virulence factors that contribute to the formation of new pathovars.

Agrobacterium-Mediated Horizontal Gene Transfer
1998Tumor- and root-inducing Agrobacterium species (e.g., A. tumefaciens, A. rhizogenes, A. vitis, A. rubi) mediate the transfer of a specific genetic element into plants. This element, known as the T-DNA, is a specific segment of a large resident Ti (or Ri depending on the species) plasmid, and is processed and transferred by protein products encoded by ...
