Molecular identification, phylogeny and geographic distribution of Brazilian mangrove oysters (Crassostrea)

Oysters (Ostreidae) manifest a high degree of phenotypic plasticity, whereby morphology is of limited value for species identification and taxonomy. By using molecular data, the aim was to genetically characterize the species of Crassostrea occurring along the Brazilian coast, and phylogenetically relate these to other Crassostrea from different parts of the world. Sequencing of the partial cytochrome oxidase c subunit I gene (COI), revealed a total of three species of Crassostrea at 16 locations along the Brazilian coast. C. gasar was found from Curuçá (Pará state) to Santos (São Paulo state), and C. rhizophorae from Fortim (Ceará state) to Florianópolis (Santa Catarina state), although small individuals of the latter species were also found at Ajuruteua...

Comparison of the effectiveness of microsatellites and SNP panels for genetic identification, traceability and assessment of parentage in an inbred Angus herd
Provedor de dados: 74
Autores: Fernández,María E.; Goszczynski,Daniel E.; Lirón,Juan P.; Villegas-Castagnasso,Egle E.; Carino,Mónica H.; Ripoli,María V.; Rogberg-Muñoz,Andrés; Posik,Diego M.; Peral-García,Pilar; Giovambattista,Guillermo.
During the last decade, microsatellites (short tandem repeats or STRs) have been successfully used for animal genetic identification, traceability and paternity, although in recent year single nucleotide polymorphisms (SNPs) have been increasingly used for this purpose. An efficient SNP identification system requires a marker set with enough power to identify individuals and their parents. Genetic diagnostics generally include the analysis of related animals. In this work, the degree of information provided by SNPs for a consanguineous herd of cattle was compared with that provided by STRs. Thirty-six closely related Angus cattle were genotyped for 18 STRs and 116 SNPs. Cumulative SNPs exclusion power values (Q) for paternity and sample matching...

The molecular phylogeny of oysters based on a satellite DNA related to transposons
Provedor de dados: 5
Autores: Lopez Flores, Inmaculada; De La Herran, R; Garrido Ramos, M; Boudry, Pierre; Ruiz Rejon, C; Ruiz Rejon, M.
We have analysed a centromeric satellite DNA family that is conserved in several commercial and non-commercial oyster species (Ostrea edulis, O. stentina, Crassostrea angulata, C gigas, C gasar, C ariakensis, C virginica and C sikamea). This satellite DNA family is composed of AT-rich repeat sequences of 166+/-2 bp and presents a 9-bp motif similar to the mammalian CENP-B box. The homology of oyster HindIII satellite DNA with satellite DNAs from other bivalves and its relation to a part of a mobile element suggest the existence of an ancient transposable element as a generating unit of satellite DNA in bivalve molluscs. Taking advantage of its degree of conservation in oyster species, we have used this element as a taxonomic marker. This marker clearly...
