Horizontal gene transfer: evidence and possible consequences.

Horizontal DNA and mRNA transfer between donor and recipient cells after allogeneic hematopoietic cell transplantation?

Allogeneic hematopoietic cell transplantation in humans results in true biological chimeras. There is now accumulating evidence that besides Graft versus Host Disease (GvHD), there are also other consequences in the co-existence of two genetically distinct populations in the transplant recipient. First, epithelial cells with donor-derived genotype emerge. Second, epithelial tissues of the host ...

III.3. Evidence for horizontal gene transfer between eukaryotes and Myxobacteria Evidence for horizontal gene transfer from Eukaryotes to Myxobacteria

Horizontal gene transfer in plants.

Horizontal gene transfer (HGT) has played a major role in bacterial evolution and is fairly common in certain unicellular eukaryotes. However, the prevalence and importance of HGT in the evolution of multicellular eukaryotes remain unclear. Recent studies indicate that plant mitochondrial genomes are unusually active in HGT relative to all other organellar and nuclear genomes of multicellular e...

Systematic Search for Evidence of Interdomain Horizontal Gene Transfer from Prokaryotes to Oomycete Lineages

While most commonly associated with prokaryotes, horizontal gene transfer (HGT) can also have a significant influence on the evolution of microscopic eukaryotes. Systematic analysis of HGT in the genomes of the oomycetes, filamentous eukaryotic microorganisms in the Stramenopiles-Alveolates-Rhizaria (SAR) supergroup, has to date focused mainly on intradomain transfer events between oomycetes an...

Recurrent Horizontal Transfer of Bacterial Toxin Genes to Eukaryotes

In this work, we report likely recurrent horizontal (lateral) gene transfer events of genes encoding pore-forming toxins of the aerolysin family between species belonging to different kingdoms of life. Clustering based on pairwise similarity and phylogenetic analysis revealed several distinct aerolysin sequence groups, each containing proteins from multiple kingdoms of life. These results stron...
