Phylogenetic relationships of 12 species of the vetigastropod family Haliotidae were analysed on the basis of partial haemocyanin coding genes. Both protein-coding and genomic sequence data, of which the latter includes one ancient intron, were analysed. We were able to distinguish two genetically different monophyletic groups with high bootstrap support: (i) the abalones from Europe, South Africa, Australia, Taiwan and Japan group together and are separated from (ii) five California and two…

Molecular phylogeny of South African abalone, its origin and evolution as revealed by two genes
TLDR
All five South African species were revealed as a monophyletic group with a sister relationship to the Australian endemics clade and a split within the South African group was revealed as well as further speciation within one of the two subclades.
Chromosome number of the South African abalone Haliotis midae
TLDR
This study is the first report for Haliotis midae, the largest and only economically important species in South Africa, with a somatic chromosome number of 2n = 36, and corroborates the hypothesis of the radiation of the genus into the Southern and Northern hemispheres from the Indo-Pacific area.
Evolution of Genome Size within the Genus Haliotis (Vetigastropoda: Haliotidae)
TLDR
The results suggest that increases in the DNA amount occurred independently in the ancestor of each of the different lineages.
Two different and functional nuclear rDNA genes in the abalone Haliotis tuberculata: tissue differential expression
TLDR
A phylogenetic analysis makes a clear separation between type I and type II ITS1 sequences and supports grouping H. coccinea and H. marmorata together and proposes a general structure of the ITS1 transcript, with four major helices for the two types.
Karyotype analysis of interspecific hybrids between Haliotis rufescens and Haliotis discus HANNAI
TLDR
A quantitative karyotype analysis inHaliotis rufescens, Haliotis discus hannai and their interspecific hybrid showed that the hybrids are successfully viable and their karyotypes evidenced a conservative chromosome number of 2n=36, and the implications of the abalone hybrid viability derived from its chromosome composition are discussed.
Identification of a potential antimicrobial peptide derived from Haliotis midae haemocyanin
TLDR
This study provides the first evidence that an antimicrobial peptide derived from the H. midae haemocyanin could be functioning as a component of the abalone innate immune response.
Genetic Variability of Cultured Populations of Red Abalone in Chile: An Approach Based on Heterologous Microsatellites
TLDR
According to the FST and RST values, there are genetic differences among the populations, with the 3 northern hatcheries from Caldera and Coquimbo more related than the abalone population of southern Chile.
Development of Gene-linked Molecular Markers in South African Abalone (Haliotis midae) Using an In silico Mining Approach
TLDR
The present study investigates and demonstrates the use of public sequence collections to develop type I markers for a species with limited genomic resources, via three strategies: Surveying anonymous H. midae microsatellite markers’ flanking regions to find homology to gene sequences in public databases, cross-species marker transfer of anonymous markers from H. rubra and H. discus hannai demonstrating putative gene associations and EST marker mining from various Haliotids and testing transfer to the target species.

Evolution and systematics in Haliotidae (Mollusca: Gastropoda): inferences from DNA sequences of sperm lysin
TLDR
Two historical hypotheses are proposed to explain the biogeography and evolution within these abalone: Tethyan distribution of the ancestral abalone, during the Cretaceous, followed by extinction in most of the habitat, but radiation in California and Southeast Asia which later spread to the other areas.
Structures of two molluscan hemocyanin genes: Significance for gene evolution
TLDR
It is proposed that the introns between FUs were generated as the eight-unit polypeptide evolved from a monomeric precursor, and that the internal introns have been added later.
Molecular systematics of the major lineages of the Gastropoda
TLDR
By virtue of their abundance and diversity in the Recent fauna, gastropods have been used in studies spanning numerous biological disciplines, including ecology, physiology, developmental biology, population genetics, biodiversity, biomechanics, biogeography, and molecular evolution.
Genetic evidence for hybridisation between Haliotis rubra and H. laevigata
TLDR
Protein electrophoresis revealed that rare, morphologically intermediate abalone are predominantly F1 hybrids; others are backcross individuals; there is also evidence of possible local introgression of H. rubra genes into H. laevigata in sympatric populations.
Distribution and biogeography of the recent Haliotidae (Gastropoda: Vetigastropoda) world-wide
TLDR
The area cladogram, which treats the distribution of the individual species as characters and the areas as taxa, is in general agreement with an unrooted phylogenetic tree of the taxa for which the geographic occurrence is superimposed.
Ontogenetic changes in the trochoidean (Archaeogastropoda) radula, with some phylogenetic interpretations
TLDR
Radulae have been examined of juvenile specimens of 18 species belonging to the Turbinidae, the Tricoliidae and 6 subfamilies of Trochidae and it is suggested that such an unspecialized starting point means a high potential for specializations and future evolution.
Gastropod phylogeny based on six segments from four genes representing coding or non-coding and mitochondrial or nuclear DNA
TLDR
Additional data was collected from three gene segments and analyses of these data using cladistic, maximum likelihood or Bayesian methodologies were conducted in an attempt to resolve some of the differences between current hypotheses of gastropod relationships based on morphological and molecular data.
Sequence of the Octopus dofleini hemocyanin subunit: structural and evolutionary implications.
TLDR
Phylogenetic analysis of the sequences of the O. dofleini functional units indicates that the multi-domain subunit structure must have arisen over a relatively brief period, preceeding the differentiation of major molluscan types.
Gastropod evolutionary rates and phylogenetic relationships assessed using partial 28S rDNA and histone H3 sequences
TLDR
The data support the monophyly of the Patellogastropoda (true limpets), Euthyneura and the ‘higher’ vetigastropods and the polyphyly ofThe ‘Cocculiniformia’, and show marked variability in the rate of evolution in both segments of the 28S rDNA, whether or not the expansion regions are included.
