Horizontal gene transfer in metazoans has been documented in only a few species and is usually associated with endosymbiosis or parasitism. [] Key Result Some of the foreign genes were defective, whereas others were intact and transcribed; some of the latter contained functional spliceosomal introns. One such gene, apparently of bacterial origin, was overexpressed in Escherichia coli and yielded an active enzyme. The capture and functional assimilation of exogenous genes may represent an important force in…

Horizontal gene transfer in bdelloid rotifers is ancient, ongoing and more frequent in species from desiccating habitats
TLDR
HGT is ongoing in bdelloids and has contributed to putative functional differences among species, and Variation among the authors' study species is consistent with the hypothesis that desiccating habitats promote HGT.
Multiple lateral gene transfers and duplications have promoted plant parasitism ability in nematodes
TLDR
It is reported that independent lateral gene transfers from different bacteria, followed by gene duplications and early gain of introns, have shaped this repertoire of plant parasitism in nematodes.
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.
Lateral Gene Transfer in Multicellular Organisms
TLDR
An overview and discussion of the many recent examples of LGT in animals with examination of important studies in plant LGT and differentiate LGT from adaptive hybridization are provided.
The Genome of the Fungal Pathogen Verticillium dahliae Reveals Extensive Bacterial to Fungal Gene Transfer
TLDR
This work systematically searched for evidence of inter-kingdom HGT events in the genome of V. dahliae and provides evidence for extensive horizontal gene acquisition from bacterial origin.
Horizontal gene transfers in insects.
Multiple horizontally acquired genes from fungal and prokaryotic donors encode cellulolytic enzymes in the bdelloid rotifer Adineta ricciae.
Horizontal gene transfer in eukaryotic evolution
TLDR
The number of well-supported cases of transfer from both prokaryotes and eukaryotes, many with significant functional implications, is now expanding rapidly and major recent trends include the important role of HGT in adaptation to certain specialized niches and the highly variable impact of H GT in different lineages.
Biochemical Diversification through Foreign Gene Expression in Bdelloid Rotifers
TLDR
Bdelloid rotifers express horizontally acquired genes on a scale unprecedented in animals, and foreign genes make a profound contribution to their metabolism, which represents a potential mechanism for ancient asexuals to adapt rapidly to changing environments and thereby persist over long evolutionary time periods in the absence of sex.
Genomic evidence for ameiotic evolution in the bdelloid rotifer Adineta vaga
TLDR
The genome of a bdelloid rotifer, Adineta vaga, is reported and it is shown that its structure is incompatible with conventional meiosis, and abundant evidence of gene conversion is found, which may limit the accumulation of deleterious mutations in the absence of meiosis.

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.

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.

Evidence for degenerate tetraploidy in bdelloid rotifers
TLDR
This work sequenced 45- to 70-kb regions surrounding the four copies of the hsp82 gene of the bdelloid rotifer Philodina roseola, each of which is on a separate chromosome, to propose that bdlloid colinear chromosome pairs are maintained as templates for the repair of DNA double-strand breaks caused by the frequent desiccation and rehydration characteristic of bdellsoid habitats.
Widespread Lateral Gene Transfer from Intracellular Bacteria to Multicellular Eukaryotes
TLDR
It is shown that some of these inserted Wolbachia genes are transcribed within eukaryotic cells lacking endosymbionts, potentially providing a mechanism for acquisition of new genes and functions.

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).
Genome fragment of Wolbachia endosymbiont transferred to X chromosome of host insect
TLDR
Results strongly suggest that wBruAus has no microbial entity but is a genome fragment of Wolbachia endosymbiont transferred to the X chromosome of the host insect.
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.
