Abstract  A new putative transposon was identified in the tobacco budworm, Heliothis virescens. This transposon was characterized as a full length CORE‐SINE (65 bp of “CORE” core specific nucleotide short interspersed elements) that resembled sequences from three other lepidopterans and humans. In particular, the A‐box and B‐box regions of this sequence most closely conformed to the signature of CORE‐SINEs from widely divergent species. This CORE‐SINE was present as a polymorphism in a… 

Expansion of CORE-SINEs in the genome of the Tasmanian devil

It is evident that the early phases of evolution of the carnivorous marsupial order Dasyuromorphia was characterized by a burst of SINE activity, and the radiation and abundance of CORE-SINEs in Marsupial genomes indicates that they may be a major player in the evolution of marsupials.



Intact mariner‐like element in tobacco budworm, Heliothis virescens (Lepidoptera: Noctuidae)

An intact mariner‐like element was isolated from the genome of tobacco budworm, Heliothis virescens, andylogenetic analysis demonstrated that Hvmar1 belongs to the irritans subfamily.

Transposable elements in lepidoptera: hobo-like transposons in Heliothis virescens and Helicoverpa zea.

Analysis of the DNA sequence and the single open reading frame found within these fragments clearly demonstrates that these elements are closely related to the hobo transposon from Drosophila melanogaster.

First application of the SINE (short interspersed repetitive element) method to infer phylogenetic relationships in reptiles: an example from the turtle superfamily Testudinoidea.

The present study represents the first application of this method to a phylogenetic analysis of this class of vertebrates, and it provides detailed information on the SINE subgroups and types of hidden-necked turtles.

Short interspersed elements (SINEs) are a major source of canine genomic diversity.

The high frequency of bimorphic SINE insertions in the dog population is predicted to provide numerous examples of allele-specific transcription patterns that will be valuable for the study of differential gene expression among multiple dog breeds.

Evolutionary inventions and continuity of CORE-SINEs in mammals.

A model in which new CORE-families, with distinct 3'-segments, are created at the RNA level due to template switching between LINE and Core-RNA during reverse transcription is proposed.

Retrotransposon insertion in SILV is responsible for merle patterning of the domestic dog

Data show that SILV is responsible for merle patterning and is associated with impaired function of the auditory and ophthalmologic systems, which makes it an intriguing candidate gene for human auditory–pigmentation disorders.

It is proposed that the core identifies an ancient tRNA-like SINE element, which survived in different lineages such as mammals, reptiles, birds, and fish, as well as mollusks, presumably for >550 million years.

Molecular Population Genetics of Sodium Channel and Juvenile Hormone Esterase Markers in Relation to Pyrethroid Resistance in Heliothis virescens (Lepidoptera: Noctuidae)

It is concluded that one or more mutations elsewhere in the hscp gene confer resistance to pyrethroids in populations of H. virescens through positive linkage disequilibrium between Hpy3 and presumed resistance-conferring allele(s) at another locus.

The Heliothis virescens cadherin protein expressed in Drosophila S2 cells functions as a receptor for Bacillus thuringiensis Cry1A but not Cry1Fa toxins.

It is demonstrated that HevCaLP is a functional Cry1A but not Cry1Fa receptor, which suggests the possibility of evolution of cross resistance via alteration of Hev CaLP.

Voltage‐gated sodium channel genes hscp and hDSC1 of Heliothis virescens F. genomic organization

The genomic sequence of hscp, a sodium channel α subunit gene for Heliothis virescens, contained thirty‐one deduced exons with a translation of 1695 residues and overall amino acid similarity to the para locus of Drosophila melanogaster was 86%.
