Horizontal gene transfer (HGT; also known as lateral gene transfer) has had an important role in eukaryotic genome evolution, but its importance is often overshadowed by the greater prevalence and our more advanced understanding of gene transfer in prokaryotes. Recurrent endosymbioses and the generally poor sampling of most nuclear genes from diverse lineages have also complicated the search for transferred genes. Nevertheless, the number of well-supported cases of transfer from both… Expand
Functional and ecological impacts of horizontal gene transfer in eukaryotes.

  • Biology, Medicine
  • Current opinion in genetics & development
  • 2009
TLDR
Several cases of HGT conferring a plausible adaptive advantage are reviewed to examine emerging trends in such transfer events and seem to play an important role in adaptation to parasitism and pathogenesis, as well as to other specific environmental conditions such as anaerobiosis or nitrogen and iron limitation in marine environments.

  • Jinling Huang

  • BioEssays : news and reviews in molecular, cellular and developmental biology
  • 2013
TLDR
A model of HGT is proposed that suggests both unicellular and early developmental stages as likely entry points for foreign genes into multicellular eukaryotes, and indicates that no insurmountable barrier to HGT exists, even in complex multICEllular eUKaryotes. Expand
Gene transfer and diversification of microbial eukaryotes.

  • 2009
TLDR
The role of gene transfer in the diversification process of microbial eukaryotes currently is underestimated and Rigorous systematic studies of gene acquisitions that allow for the possibility of exchanges of all categories of genes from all sources are needed. Expand
Lateral Gene Transfer Mechanisms and Pan-genomes in Eukaryotes.
TLDR
Evidence for known and potential mechanisms and trends emerging from recently reported examples of LGT into diverse eukaryote lineages are reviewed, with a particular focus on protists, and the potential role ofLGT in generating 'pan-genomes' in diverse Eukaryotic species is explored. Expand
Horizontal gene transfer: Its impacts and influences
TLDR
The current review has highlighted about the different types of horizontal gene transfer, factors affecting the HGT its benefits and its impact on nutritional value. Expand
Horizontal Gene Transfer
TLDR
Across the eukaryotes the impact of HGT was irregular and for acquiring the new genes some other lineages are appearing to be immune. Expand
Horizontal gene transfer in the acquisition of novel traits by metazoans
  • L. Boto
  • Biology, Medicine
  • Proceedings of the Royal Society B: Biological Sciences
  • 2014
TLDR
Suspected examples in sponges, cnidarians, rotifers, nematodes, molluscs and arthropods suggest that horizontal gene transfer in metazoans is not simply a curiosity, and the scarcity of studies in vertebrates and other animal groups is stressed. Expand
Horizontal gene transfer in the evolution of photosynthetic eukaryotes
TLDR
There is clear evidence that anciently acquired genes played an important role in the establishment of primary plastids and in the transition of plants from aquatic to terrestrial environments and reliable approaches are needed to distinguish endosymbionts‐derived genes from those independently acquired from preferential feeding or other activities.

Lateral gene transfer between prokaryotes and multicellular eukaryotes: ongoing and significant?
TLDR
It is argued that the transfer of genes between host and symbiont may occasionally be of great evolutionary importance, particularly in the evolution of the symbiotic interaction itself. Expand
Horizontal Acquisition of Prokaryotic Genes for Eukaryote Functioning and Niche Adaptation
TLDR
Different cases of intra- and inter-domain HGT conferring an adaptive advantage to eukaryotes are reviewed to examine novel trends and HGT paradigms and appear to play an important role in eUKaryotic adaptation to specific environmental conditions. Expand

Lateral gene transfer in eukaryotes
  • J. Andersson

  • 2005
TLDR
Findings in this work indicate that lateral gene transfer frequently occurs in protists with phagotrophic lifestyles, possibly with rates comparable to prokaryotic organisms, and have implications for eukaryotic genomic research in general, and studies of the origin and phylogeny of eucaryotes in particular. Expand
Horizontal gene transfer in plants.
TLDR
A case of massive HGT in Amborella trichopoda is uncovered involving acquisition of at least a few dozen and probably hundreds of foreign mitochondrial genes, which will examine the implications of such massive transfer, the potential mechanisms and consequences of plant-to-plant mitochondrial H GT in general, as well as the limited evidence in plant chloroplast and nuclear genomes. Expand
Ancient horizontal gene transfer can benefit phylogenetic reconstruction.
TLDR
The recent progress in phylogenetic application of ancient HGTs is discussed and two examples of transfer events to the ancestor of red algae and green plants that support a common origin of these two groups are described. Expand
Widespread horizontal transfer of mitochondrial genes in flowering plants
TLDR
It is shown that standard mitochondrial genes, encoding ribosomal and respiratory proteins, are subject to evolutionarily frequent horizontal transfer between distantly related flowering plants, implying the existence of mechanisms for the delivery of DNA between unrelated plants and indicating that horizontal transfer is also a force in plant nuclear genomes. Expand
Horizontal gene transfer in chromalveolates
TLDR
Recurring intra- and interdomain gene exchange provides an important source of genetic novelty not only in parasitic taxa as previously demonstrated but as the show here, also in free-living protists. Expand

TLDR
It is proposed that a major factor in the more frequent horizontal transfer of operational genes is that informational genes are typically members of large, complex systems, whereas operational genes are not, thereby making horizontalTransfer of informational gene products less probable (the complexity hypothesis).

Massive Horizontal Gene Transfer in Bdelloid Rotifers
TLDR
In bdelloid rotifers, many genes that appear to have originated in bacteria, fungi, and plants are found, concentrated in telomeric regions along with diverse mobile genetic elements. Expand
Horizontal gene transfer in prokaryotes: quantification and classification.
TLDR
The fixation and long-term persistence of horizontally transferred genes suggests that they confer a selective advantage on the recipient organism, and the nature of this advantage remains unclear, but detailed examination of several cases of acquisition of eukaryotic genes by bacteria seems to reveal the evolutionary forces involved.

Phylogenetic Analyses of Diplomonad Genes Reveal Frequent Lateral Gene Transfers Affecting Eukaryotes
TLDR
Phylogenetic analyses of 15 genes present in the genome of the Atlantic Salmon parasite Spironucleus barkhanus and the intestinal parasite Giardia lamblia show that most of these genes originated via LGT, showing that LGT is a significant evolutionary mechanism among diplomonads in particular and protists in general.
