Mobile Genetic Elements span the tree of life, and in many ways are just as diverse as their host organisms. This diversity can be hard to grasp, especially since few researchers work on a wide variety of elements. With that in mind this list was compiled to catalog a variety of elements that may be unfamiliar to researchers who focus on Eukaryotic or Prokaryotic MGEs exclusively. It includes phylogenetic groups of elements but also phenetic groups of elements that do not fit into the traditional phylogeny-based classification systems, or whose origins are not known. It also includes information on whether the elements in question use their own proteins to mobilize, or rely on the proteins of other elements.
This list is maintained by Tyler A. Elliott. Suggestions, updates and error corrections can be directed to Tyler, or by making changes to this page itself.
