We tested cross-species amplification of 68 existing microsatellite loci in 6 species of the Sparidae family: Acanthopagrus butcheri, Sparus aurata, Pagrus auratus, Chrysophrys major, Pagellus bogaraveo, Pagellus erythrinus and one species of Bothidae, Paralichthys olivaceus. Of the 68 loci screened, sixteen were found to be polymorphic when tested in 20 individual black sea bream, Acanthopagrus schlegeli. The number of alleles per locus ranged from 2 to 9, and the observed and expected heterozygosity ranged from 0.55 to 0.95, and from 0.58 to 0.87, respectively. Our results show that cross-species amplification of known microsatellite loci in closely related species is a highly promising source of microsatellite markers for A. schlegeli.
Résumé
Nous testons l'amplification interspécifique de 68 locus de microsatellites existants de six espèces de Sparidés : Acanthopagrus butcheri, Sparus aurata, Pagrus auratus, Chrysophrys major, Pagellus bogaraveo, Pagellus erythrinus et une espèce de Bothidé, Paralichthys olivaceus. Des 68 locus étudiés, seize sont polymorphes lorsqu'ils sont testés chez 20 individus de Acanthopagrus schlegeli. Le nombre d'allèles par locus varie de 2 à 9, et l'hétérozygosité (la diversité génétique) s'étend de 0,55 à 0,95, et de 0,58 à 0,87, respectivement. Nos résultats montrent que l'amplification interspécifique de locus de microsatellites chez des espèces proches est une source prometteuse de marqueurs de microsatellites pour A. schlegeli.
