Hidden species diversity and mito-nuclear discordance within the Mediterranean ...
Abalde, Samuel; Crocetta, Fabio; Tenorio, Manuel J.; D'Aniello, Salvatore; Fassio, Giulia; Rodríguez-Flores, Paula C.; Uribe, Juan E.; Afonso, CarlosThe Mediterranean cone snail, Lautoconus ventricosus, is currently considered a single species inhabiting the whole Mediterranean basin and the adjacent Atlantic coasts. Yet, no population genetic study has assessed its taxonomic status. Here, we collected 245 individuals from 75 localities throughout the Mediterranean Sea and used cox1 barcodes, complete mitochondrial genomes, and genome skims to test whether ...
The genome of the venomous snail Lautoconus ventricosus sheds light on the orig...
Pardos-Blas, José Ramón; Irisarri, Iker; Abalde, Samuel; Afonso, Carlos; Jimenez-Tenorio, M.; Zardoya, RafaelVenoms are deadly weapons to subdue prey or deter predators that have evolved independently in many animal lineages. The genomes of venomous animals are essential to understand the evolutionary mechanisms involved in the origin and diversification of venoms.
Mitogenomic phylogeny of mud snails of the mostly Atlantic/Mediterranean genus ...
Yang, Yi; Abalde, Samuel; Afonso, Carlos L. M.; Tenorio, Manuel J.; Puillandre, Nicolas; Templado, Jose; Zardoya, RafaelThe mud snails endemic to the East Atlantic/Mediterranean region (genus Tritia; subfamily Nassariinae) account for the second highest diversity within the family Nassariidae (Gastropoda: Buccinoidea). In order to understand how the diversity of species, shell morphologies and ecological traits evolved within this genus, a robust phylogenetic framework is needed, yet still unavailable due to high levels of homop...
Comparative transcriptomics of the venoms of continental and insular radiations...
Abalde, Samuel; Tenorio, Manuel J.; Afonso, Carlos; Zardoya, RafaelThe transcriptomes of the venom glands of 13 closely related species of vermivorous cones endemic to West Africa from generaAfriconusandVarioconuswere sequenced and venom repertoires compared within a phylogenetic framework using oneKalloconusspecies as outgroup. The total number of conotoxin precursors per species varied between 108 and 221. Individuals of the same species shared about one-fourth of the total ...
Conotoxin diversity in Chelyconus ermineus (Born, 1778) and the convergent orig...
Abalde, Samuel; Tenorio, Manuel J.; Afonso, Carlos; Zardoya, RafaelThe transcriptome of the venom duct of the Atlantic piscivorous cone species Chelyconus ermineus (Born, 1778) was determined. The venom repertoire of this species includes at least 378 conotoxin precursors, which could be ascribed to 33 known and 22 new (unassigned) protein superfamilies, respectively. Most abundant superfamilies were T, W, O1, M, O2, and Z, accounting for 57% of all detected diversity. A total...
Mitogenomic phylogeny of cone snails endemic to Senegal
Abalde, Samuel; Tenorio, Manuel J.; Afonso, Carlos; Zardoya, RafaelCone snails attain in Senegal one of their highest peaks of species diversity throughout the continental coast of Western Africa. A total of 15 endemic species have been described, all placed in the genus Lautoconus. While there is ample data regarding the morphology of the shell and the radular tooth of these species, virtually nothing is known regarding the genetic diversity and phylogenetic relationships of ...
Phylogenetic relationships of cone snails endemic to Cabo Verde based on mitoch...
Abalde, Samuel; Tenorio, Manuel J.; Afonso, Carlos; Uribe, Juan E.; Echeverry, Ana M.; Zardoya, RafaelBackground: Due to their great species and ecological diversity as well as their capacity to produce hundreds of different toxins, cone snails are of interest to evolutionary biologists, pharmacologists and amateur naturalists alike. Taxonomic identification of cone snails still relies mostly on the shape, color, and banding patterns of the shell. However, these phenotypic traits are prone to homoplasy. Therefo...
