From: Horizontal transfer of a non-autonomous Helitron among insect and viral genomes
Phylogenetic relationship among Helitron-like Hel-2 elements horizontally transferred among insects and viruses. Maximum likelihood (ML) estimation among Hel-2 elements in genomes of moths, butterflies, hymenopteran parasitoids, a hemipteran gall former, and insect viruses. using the Tamura-3-Parameter model and Gamma shape parameter of 2.249. Bootstrap support is indicated at each node of the consensus tree when values were ≥ 50%, whereas unresolved branches exist for all other instances. Resulting tree has a Log Likelihood = − 1908.7; total branch length of 5.438. Species definitions: Moths: Family Bombycidae, Bombyx mori; Family Crambidae, Ostrinia nubilalis and Maruca vitrata; Family Noctuidae, Agrotis sgatum, Helicoverapa armigera, Heliothis virescens, Spodoptera frugiperda, S. exigua, and S. littoralis; Family Tortricidae, Choristoneura fumiferana and Epiphyas postvittana, Family Plutellidae, Plutella xylostella Butterflies: Family Pieridae, Colias eurytheme and C. behrri, Family Papilionidae, Papilio xuthus; Family Nymphalidae, Heliconius erato, H. numata and H. melpomene. *C. vestalis TSA submissions determined to share flanking sequence with CvBV segements and are suggested to comprise transcripts derived from viral integrations.
