The nuclear small subunit rRNA (18S) has played a dominant role in the estimation of relationships among insect orders from molecular data. In previous studies, 18S sequences have been aligned by unadjusted automated approaches (computer alignments that are not manually readjusted), most recently with direct optimization (simultaneous alignment and tree building using a program called "POY"). Parsimony has been the principal optimality criterion. Given the problems associated with the alignment…

A molecular phylogeny of Hexapoda
TLDR
A supermatrix approach to the phylogeny of Insecta that stemmed from a talk given at the 2 Dresden Meeting on Insect Phylogeny (2005) is presented, suggesting that the elucidation of relationships between non-holometabolous neopteran orders is far from resolved.
Nearly complete rRNA genes from 371 Animalia: updated structure-based alignment and detailed phylogenetic analysis.
Nematode small subunit phylogeny correlates with alignment parameters.
The number of nuclear small subunit (SSU) ribosomal RNA (rRNA) sequences for Nematoda has increased dramatically in recent years, and although their use in constructing phylogenies has also
Molecular phylogeny of the higher taxa of Odonata (Insecta) inferred from COI, 16S rRNA, 28S rRNA, and EF1‐α sequences
TLDR
This study sequenced both two mitochondrial genes and nuclear genes from 71 species of Odonata that represent 7 superfamilies in 3 suborders to support the suborders Anisoptera and Zygoptera each being a monophyly, and the close relationship of Anisozygoptera to An isoptera.
Accurate and efficient reconstruction of deep phylogenies from structured RNAs
TLDR
The RNAsalsa approach, based on the improved accuracy of pairwise consensus structures and informed by a priori knowledge of group-specific structural constraints, provides both alignments and consensus structures that are of sufficient accuracy for routine phylogenetic analysis based on RNA-specific substitution models.
The mitochondrial genomes of palaeopteran insects and insights into the early insect relationships
TLDR
A next-generation sequencing approach was used to reconstruct new mitochondrial genomes from 18 species of basal insects, including six representatives of Ephemeroptera and 11 of Odonata, plus one species belonging to Zygentoma, which generally recovered Zygentomas as a monophyletic group, which formed a sister group to Pterygota.

18S Ribosomal RNA genes of insects : primary structure of the genes and molecular phylogeny of the Holometabola
TLDR
A sister group relationship of the Strepsiptera and the Diptera was found with both methods and with corrections for different substitution rates at different sites and for differences in the nucleotide composition.
Effects of nucleotide sequence alignment on phylogeny estimation: a case study of 18S rDNAs of apicomplexa.
TLDR
This empirical study inferred phylogenetic trees for 43 species of the Apicomplexa and 3 of Dinozoa based on complete small-subunit rDNA sequences using six different multiple-alignment procedures, and concluded that the helical regions are the most informative.
18S ribosomal RNA and tetrapod phylogeny.
TLDR
This research indicates that the previous discrepancy of phylogenetic results between the 18S rRNA gene and other genes is caused mainly by the misalignment of the sequences, the inappropriate use of the frequency parameters, and poor sequence quality.
Effects of sequence alignment and structural domains of ribosomal DNA on phylogeny reconstruction for the protozoan family sarcocystidae.
TLDR
This work shows that congruence between different methods in the formation of clades may be a feature of robust topology; however, a sequence alignment based on primary structure may not be comparing homologous nucleotides even though the expected topology is obtained.

TLDR
Suggestions for alignment, data presentation, and character description are made in the context of an example from frog large subunit nuclear rRNA, where improved congruence with previously published morphological conclusions and the format used in data presentation facilitated the description of character-based conclusions at each node in the cladogram.
Hierarchical analysis of variation in the mitochondrial 16S rRNA gene among Hymenoptera.
TLDR
This study finds that the 16S gene is most informative for phylogenetic analysis at two different levels: among closely related species or populations, and among tribes, subfamilies, and families.
The effectiveness of mitochondrial rRNA gene sequences for the reconstruction of the phylogeny of an insect order (Orthoptera).
TLDR
It seems that increasing either or both the number of taxa or nucleotide positions will not necessarily solve all problems, and the resolution of ancient branching events using mtDNA sequences probably depends upon the development and application of better specified reconstruction methods.

Systematics of holometabolous insect orders based on 18S ribosomal RNA.
TLDR
Parsimony analyses resolved relationships in a few groups but left the most controversial questions regarding relationships among major lineages unresolved, and all analyses supported a clade with Lepidoptera and Trichoptera as sister taxa most closely related to Diptera.
