Evolution, weighting, and phylogenetic utility of mitochondrial gene sequences and a compilation of conserved polymerase chain reaction primers
DNA-sequence data from the mitochondrial genome are being used with increasing frequency to estimate phylogenetic relationships among animal taxa. The advantage to using DNA-sequence data is that… Expand
The sequence, organization, and evolution of the Locusta migratoria mitochondrial genome
The sequencing of the cloned Locusta migratoria mitochondrial genome has been completed. The sequence is 15,722 by in length and contains 75.3% A+T, the lowest value in any of the five insect… Expand
Methods for the preservation of insects for DNA studies
Abstract Adult Simulium damnosum s.l. were reared from pupae and preserved in liquid nitrogen, Carnoy's solution, formal saline, three alcohols at a variety of concentrations, dried over silica gel… Expand
Inferences about orthopteroid phylogeny and molecular evolution from small subunit nuclear ribosomal DNA sequences
We determined DNA sequences of SSU rRNA genes in twenty‐nine polyneopteran insect species and aligned these with homologues from eight other insects. In a phylogenetic analysis we recovered the… Expand
Combined molecular phylogenetic analysis of the Orthoptera (Arthropoda, Insecta) and implications for their higher systematics.
A phylogenetic analysis of mitochondrial and nuclear rDNA sequences from species of all the superfamilies of the insect order Orthoptera (grasshoppers, crickets, and relatives) confirmed that… Expand
The phylogeny of the Caelifera (Insecta, Orthoptera) as deduced from mtrRNA gene sequences.
Fragments of both mitochondrial ribosomal RNA genes of 32 caeliferan taxa (representing six of the seven superfamilies) and six outgroup Orthopteroids were sequenced. The combined alignment length… Expand

We describe a new ab initio method and corresponding program, LOOPER, for the prediction of protein loop conformations. The method is based on a multi-step algorithm (developed as a set of CHARMm… Expand
The effectiveness of mitochondrial rRNA gene sequences for the reconstruction of the phylogeny of an insect order (Orthoptera).
We investigated the value of mitochondrial rRNA sequences for analyzing pre-Cainozoic divergence events in insects. Using small subunit and large subunit rRNA sequences from 38 orthopteroid species,… Expand

Molecular phylogenetic analysis of the Pneumoroidea (Orthoptera, Caelifera): molecular data resolve morphological character conflicts in the basal acridomorpha.
A key transition in the evolution of the insect suborder Caelifera (Orthoptera; Insecta) was from predominantly non-angiosperm-feeding basal lineages to the modern acridomorph fauna (grasshoppers and… Expand
