Summary We resolve debate over the evolution of vertebrate hypermineralized tissues through analyses of matrix protein-encoding secretory calcium-binding phosphoprotein (SCPP) genes and phylogenetic inference of hypermineralized tissues. Among these genes, AMBN and ENAM are found in both sarcopterygians and actinopterygians, whereas AMEL and SCPP5 are found only in sarcopterygians and actinopterygians, respectively. Actinopterygian AMBN, ENAM, and SCPP5 are expressed during the formation of… Expand

Transcriptomic profiling of tissue environments critical for post-embryonic patterning and morphogenesis of zebrafish skin
TLDR
A previously undescribed population of ameloblast-like epidermal cells is revealed, hormonal control of epithelial-mesenchymal signaling is suggested, the signaling network that governs scale papillae development is clarified, and the hypodermis is identified as a crucial pigment cell support environment.

TLDR
The three Pro/Gln-rich SCPP genes, required for mineralizing enamel matrix and confirmed only in tetrapods, were all identified in the coelacanth, strongly suggesting that enamel is equivalent in theCoelacant and tetrapod, corroborates the previous proposition that true enamel evolved much earlier than the origin of tetrapoda.

TLDR
Positive immunoreactivity to the anti-mammalian amelogenin antibodies by the preganoine of both Polypteridae and Lepisosteidae supports that ganoine is a homolog of tooth enamel. Expand

TLDR
The repertoire of SCPP genes in the zebrafish, frog, and humans includes many lineage-specific genes and some widely conserved genes that originated in stem osteichthyans or earlier, reinforcing the hypothesis that bone–dentin–enameloid–enameless constitutes an evolutionary continuum. Expand
Evolution of dental tissue mineralization: an analysis of the jawed vertebrate SPARC and SPARC-L families
TLDR
The results suggest the ameloblastic expression of the single chondrichthyan SPARC-L gene at the maturation stage reflects the ancestral gnathostome situation, and provide new evidence in favor of the homology of enamel and enameloids in all Gnathostomes. Expand
Distribution and variation in enamel structure in the oral teeth of sarcopterygians: Its significance for the evolution of a protoprismatic enamel
TLDR
The property of tooth enamel to resist alteration during fossilization, is used to analyse the unique arrangements of biological crystallites amongst genera of Paleozoic sarcopterygians, and it is established that types of monotypic enamel are present in both actinopteryGians and sarcoperygia.

SCPP Genes and Their Relatives in Gar: Rapid Expansion of Mineralization Genes in Osteichthyans.
TLDR
It appears that many SCPP genes expanded rapidly in stem osteichthyans and in basal actinopterygians, including many newly identified P/Q-rich genes expressed in teeth and/or scales. Expand
New genomic and fossil data illuminate the origin of enamel
TLDR
It is shown that Psarolepis romeri, a bony fish from the the Early Devonian period, combines enamel-covered dermal odontodes on scales and skull bones with teeth of naked dentine, and that Lepisosteus oculatus (the spotted gar) has enam and ambn genes that are expressed in the skin, probably associated with ganoine formation.

Immunolocalization of enamel matrix protein-like proteins in the tooth enameloid of spotted gar, Lepisosteus oculatus, an actinopterygian bony fish
TLDR
The enameloids matrix during the stages of enameloid formation in spotted gar, Lepisosteus oculatus, an actinopterygian, was examined mainly by transmission electron microscopy-based immunohistochemistry using an anti-mammalian amelogenin antibody and antiserum. Expand
The Evolution of Unusually Small Amelogenin Genes in Cetaceans; Pseudogenization, X–Y Gene Conversion, and Feeding Strategy
TLDR
It is speculated that common ancestors of modern cetaceans employed a degenerate AMELX, transferred from a decaying AMELY by gene conversion, at an early stage of their transition to suction feeders. Expand
Testing models of dental development in the earliest bony vertebrates, Andreolepis and Lophosteus
TLDR
These fossil remains have no bearing on the nature of the dentition in osteichthyans and, indeed, the results raise questions concerning the homologies of these bones and the phylogenetic classification of Andreolepis and Lophosteus. Expand
