Horizontal Gene Transfer in Fungi [PDF]
, 2020 Horizontal gene transfer (HGT), the sharing of genes between species outside of inheritance, is a common feature among prokaryotes, but a growing body of evidence supports HGT in eukaryotic genomes. The driving forces behind horizontal gene transfer occur within a shared environment and are selective—meaning they improve survivability of stress ...

Horizontal gene transfer into the genomes of insects [PDF]
Russian Journal of Genetics, 2016 Horizontal gene transfer (HGT) is widespread in the world of prokaryotes, but the examples of this phenomenon among multicellular animals, particularly insects, are few. This review examines the transfer of genetic material to the nuclear genomes of insects from the mitochondrial genome (intracellular HGT), as well as from the genomes of viruses ...

Horizontal Gene Transfer in Choanoflagellates
Journal of Experimental Zoology Part B: Molecular and Developmental Evolution, 2012AbstractHorizontal gene transfer (HGT), also known as lateral gene transfer, results in the rapid acquisition of genes from another organism. HGT has long been known to be a driving force in speciation in prokaryotes, and there is evidence for HGT from symbiotic and infectious bacteria to metazoans, as well as from protists to bacteria.

Monitoring and modeling horizontal gene transfer
Nature Biotechnology, 2004Monitoring efforts have failed to identify horizontal gene transfer (HGT) events occurring from transgenic plants into bacterial communities in soil or intestinal environments. The lack of such observations is frequently cited in biosafety literature and by regulatory risk assessment.

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.

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 ...

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.

Horizontal Gene Transfer and Microevolution in Soil
2006High-throughput methods for DNA sequencing have cataloged the composition of thousands of bacterial genomes, including those of many soil bacteria. Regardless of the impact of ecological factors on bacterial microevolution, whole-genome sequencing and comparative genome analysis do provide strong and compelling evidence for the importance of horizontal
