Abstract The Cyclostomata consists of the two orders Myxiniformes (hagfishes) and Petromyzoniformes (lampreys), and its monophyly has been unequivocally supported by recent molecular phylogenetic studies. [...] Key Method Under this updated vertebrate phylogeny, we performed in silico evolutionary analyses using currently available cDNA sequences of cyclostomes. We first calculated the GC-content at four-fold degenerate sites (GC4), which revealed that an extremely high GC-content is shared by all the lamprey…Expand
Insights into Cyclostome Phylogenomics: Pre-2R or Post-2R
  • S. Kuraku
  • Biology, Medicine
  • Zoological science
  • 2008
TLDR
The hypothesis that two-round (2R) genome duplication events occurred before the divergence between cyclostomes and gnathostomes, and therefore that a post-2R state is a genomic synapomorphy for all extant vertebrates is focused on. Expand

TLDR
Current controversy and future perspectives of cyclostome genomics are discussed with reference to evolutionary developmental biology. Expand
The complete mitogenome of two Australian lampreys: mordacia mordax and mordacia praecox
TLDR
The recovered topology strongly supported the hypothesis that lampreys separated from hagfishes about 409 MYA, and that lamprey divergence involved the early radiation of Mordaciidae followed by the monophyletic divergence of Geotriidae plus Petromyzontidae about 85 MYA. Expand
microRNAs reveal the interrelationships of hagfish, lampreys, and gnathostomes and the nature of the ancestral vertebrate
TLDR
Fundamental conservation of microRNA expression patterns among lamprey, hagfish, and gnathostome organs, implying that the role of microRNAs within specific organs is coincident with their appearance within the genome and is conserved through time, support the monophyletic of cyclostomes and suggest that the last common ancestor of all living vertebrates was a more complex organism than conventionally accepted. Expand
Minnows and molecules: resolving the broad and fine-scale evolutionary patterns of Cypriniformes
TLDR
To provide robust support for relationships at various taxonomic levels within Cypriniformes, an anchored hybrid enrichment approach was used to resolve relationships and a revised, genus-level taxonomy for the group is presented. Expand
Cyclostome embryology and early evolutionary history of vertebrates.
TLDR
Comparison of the lamprey and gnathostome developmental patterns suggests some plesiomorphic traits of vertebrates that would have already been established in the most recent common ancestor of the vertebrates. Expand
The evolution of lamprey (Petromyzontida) life history and the origin of metamorphosis
TLDR
A review synthesizes findings and concludes that the ancestral lamprey life cycle followed a direct development, suggesting that the larval period was short and relatively limited if present at all, but that the juvenile included modern larval traits. Expand
Hagfish from the Cretaceous Tethys Sea and a reconciliation of the morphological–molecular conflict in early vertebrate phylogeny
TLDR
By addressing nonindependence of characters, phylogenetic analyses recovered hagfish and lampreys in a clade of cyclostomes (congruent with the cyclostome hypothesis) using only morphological data, which potentially resolve the morphological–molecular conflict at the base of the Vertebrata. Expand
Unresolved orthology and peculiar coding sequence properties of lamprey genes: the KCNA gene family as test case
TLDR
The results suggest that secondary modifications of sequence properties unique to the lamprey lineage may be one of the factors preventing robust orthology assessments of lamprey genes, which deserves further genome-wide validation. Expand
Early Jawless Vertebrates and Cyclostome Origins
TLDR
The anatomy and physiology of lampreys and hagfishes are so different that it is difficult to reconstruct an ancestral morphotype of the cyclostomes, assuming that they are a clade, and there is no clear evidence of any fossil taxon that is neither a fossil hagfish nor a fossil lamprey, but would be more closely related to the Cyclostomes than to the gnathostomes.

28S and 18S rDNA sequences support the monophyly of lampreys and hagfishes.
TLDR
Moderate to very strong support is provided for the monophyly of the cyclostomes in lampreys plus hagfishes and the currently accepted hypothesis of a lamprey-gnathostome clade is moderately rejected by the Kishino-Hasegawa test and resoundingly rejected by parametric bootstrap tests. Expand
Monophyly of Lampreys and Hagfishes Supported by Nuclear DNA–Coded Genes
TLDR
Cl cloning and sequencing of the four nuclear DNA–coded single-copy genes encoding the triose phosphate isomerase, calreticulin, and the largest subunit of RNA polymerase II and III were conducted, and it was shown that all the five proteins prefer the monophyletic tree of cyclostomes, which significantly supports the cyclostome monophyly at the level of ±1 SE. Expand
The complete nucleotide sequence of the mitochondrial DNA of the agnathan Lampetra fluviatilis: bearings on the phylogeny of cyclostomes.
TLDR
The mtDNA sequence of L. fluviatilis was used in combination with relevant mtDNA sequences for an approach to the hagfish/lamprey relationships using the maximum-parsimony, neighbor-joining, and maximum-likelihood methods, and the data collected do not support the vertebrate or the cyclostome hypothesis. Expand
Complete mitochondrial DNA of the hagfish, Eptatretus burgeri: the comparative analysis of mitochondrial DNA sequences strongly supports the cyclostome monophyly.
TLDR
Molecular data, i.e., results and those obtained using nuclear genes, conclude that hagfishes and lampreys form a clade, and unequivocally supported the monophyly of cyclostomes. Expand
Molecular phylogeny and divergence times of deuterostome animals.
TLDR
It is found that most major lineages of deuterostomes arose prior to the Cambrian Explosion of fossils and that several lineages had originated before periods of global glaciation in the Precambrian. Expand
Phylogeny of Living Parasitic Lampreys (Petromyzontiformes) Based on Morphological Data
TLDR
Relationships among the 18 extant species of parasitic lamprey (Petromyzontiformes) were determined using a cladistic analysis of 32 mainly morphological characters, revealing a trichotomy between a monophyletic northern hemisphere clade and the southern hemisphere genera Geotria and Mordacia. Expand
Phylogeny of the lamprey genus Lampetra inferred from mitochondrial cytochrome b and ND3 gene sequences
TLDR
Mitochrondrial DNA analysis resolved many previously unanswered questions concerning the phylogeny of the lamprey genus Lampetra (comprising the subgenera Entosphenus, Lethenteron, and Lampetras) using rates of molecular evolution estimated in other fish taxa. Expand
Molecular phylogeny of early vertebrates: monophyly of the agnathans as revealed by sequences of 35 genes.
TLDR
This work uses the sequences of 35 nuclear protein-encoding genes to provide definitive evidence for the monophyly of the Agnatha (jawless vertebrates, a group encompassing the hagfishes and lampreys). Expand
Evidence from 18S ribosomal RNA sequences that lampreys and hagfishes form a natural group.
TLDR
Phylogenetic comparisons of 18S ribosomal RNA sequences from two hagfishes, two lampreys, a tunicate, a lancelet, and a number of gnathostomes support the monophyly of the cyclostomes, forcing a reassessment of several features of early vertebrate evolution. Expand
The complete mitochondrial genome of Alligator mississippiensis and the separation between recent archosauria (birds and crocodiles).
TLDR
The complete mitochondrial genome of the alligator, Alligator mississippiensis, was sequenced and maximum-likelihood branch length data of amino acid sequences suggest that the divergence between the avian and crocodilian lineages took place at approximately equal to 254 MYA. Expand
