Horizontal gene transfer in trypanosomatids
Trends in Parasitology, 2007Trypanosomes harbour a large number of structural and biochemical peculiarities. Kinetoplast DNA, mitochondrial RNA editing, the sequestration of glycolysis inside glycosomes and unique oxidative-stress protection mechanisms (to name but a few) are found only in the members of the order Kinetoplastida. Thus, it is not surprising that they have provoked

Ancient horizontal gene transfer
Nature Reviews Genetics, 2003The cornerstone of Charles Darwin's theory of evolution is the vertical inheritance of traits from parent to offspring across successive generations. However, molecular evolutionary biologists have shown that extensive horizontal (also known as lateral) gene transfer (HGT) can occur between distantly related species.

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.

The ecology of horizontal gene transfer
Trends in GeneticsHorizontal gene transfer (HGT) generates genetic variation in populations across all domains of life; however, most studies focus on individual transfers and functional information derived therefrom. This is useful but does not consider DNA transfer more broadly, that is, nongene transfers, donor-recipient dynamics, or trends and background levels that

Horizontal gene transfers in insects
Current Opinion in Insect Science, 2015Horizontal gene transfer is the transfer of genetic material across species boundaries. Although horizontal gene transfers are relatively rare in animals, the recent rapid accumulation of genomic data has identified increasing amounts of exogenous DNA inserts in insect genomes.

Horizontal gene transfer (HGT) may be defined as any occurrence of heritable material passing between organisms, asynchronous with reproduction of the organisms. It represents replication of heritable material outside the context of parent to offspring (i.e. vertical) reproduction. Three types of evidence traditionally lead to claims of HGT.

This review explores examples of horizontal genetic transfer in eukaryotes and prokaryotes. The best understood of these involves various conserved families of transposable elements, but examples of non-transposable-element-based movement of genes or gene clusters have also been identified in prokaryotic genomes.

Horizontal gene transfers as metagenomic gene duplications
Molecular BioSystems, 2012Abstract While it is well accepted that horizontal gene transfer plays an important role in the evolution and the diversification of prokaryotic genomes, many questions remain open regarding its functional mechanisms of action and its interplay with the extant genome.

Yi chuan = Hereditas, 2005
In this paper the conception of horizontal gene transfer (HGT) was introduced,and main mode of HGT was also enumerated as follows: HGT by medium such as plasmid and virus etc., and the HGT without any medium. The transfer of genes from one species to another especially between remote species was emphasized by the information from genome sequencing. The

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 ...
