Infographic: Possible Mechanisms of Gene Transfer in Eukaryotes
Genetic studies have made it clear that eukaryotic horizontal gene transfer can and does happen. Exactly how, though, remains speculative.

Horizontally transferred genes play significant roles in eukaryotic genomes
Horizontal Gene Transfer Happens More Often Than Anyone Thought
Christie Wilcox, PhD | Jul 5, 2022 | 10+ min read
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.
Bacterial Enzyme Keeps Rotifers’ Transposable Elements in Check
Christie Wilcox, PhD | Mar 3, 2022 | 5 min read
Jumping genes in bdelloid rotifers are tamped down by DNA methylation performed by an enzyme pilfered from bacteria roughly 60 million years ago, a study finds.
First Report of Horizontal Gene Transfer Between Plant and Animal
Emma Yasinski | Mar 25, 2021 | 3 min read
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.
Giant Viruses Can Integrate into the Genomes of Their Hosts
Amanda Heidt | Nov 19, 2020 | 4 min read
Rather than introducing small chunks of DNA as other viruses do, some giant viruses can contribute more than 1 million base pairs to a host’s genome, broadening the ways in which viruses may shape eukaryote evolution.
Genes from Bacteria Likely Aided Plants’ Move to Land
Shawna Williams | Nov 15, 2019 | 2 min read
An analysis suggests that DNA cribbed from soil microbes enabled plants’ ancestors to colonize a terrestrial environment.
Horizontal Gene Transfer in Bdelloid Rotifers Questioned
Abby Olena, PhD | Jul 12, 2018 | 4 min read
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.
