Horizontally transferred genes play significant roles in eukaryotic genomes

DNA passed to and from all kinds of organisms, even across kingdoms, has helped shape the tree of life, to a large and undisputed degree in microbes and also unexpectedly in multicellular fungi, plants, and animals.

A re-analysis of sequencing data from a 2016 study of these tiny metazoans reveals possible contamination, rather than an exchange of DNA among species.

Frequent horizontal gene transfer has occurred between distantly related angiosperms

Whiteflies overcome a toxin in plants they eat through the use of the plant’s own genetic protection, likely ferried from plant to insect millions of years ago by a virus.

Staphylococcus aureus.

Foreign genes in animal genomes may be of bacterial or fungal origin, according to a new analysis.

Scientists transferred light-harvesting proteins into yeast for the first time, shining a light on the past lives of eukaryotic cells.

Genetic studies have made it clear that eukaryotic horizontal gene transfer can and does happen. Exactly how, though, remains speculative.

Horizontal gene transfer accounts for the majority of prokaryotic protein evolution
