Isolation and characterization of 13 polymorphic nuclear microsatellite primers for the widespread Indo-Pacific three-spot damselfish, Dascyllus trimaculatus, and closely related D. auripinnis.

چکیده
A set of 13 simple sequence repeat markers was developed from D. trimaculatus genomic DNA, tested for D. auripinnis and characterized using 40 individuals per species. All the loci were polymorphic with a number of alleles ranging from three to 30. Observed heterozygosities varied from 0.23 to 0.89 for D. trimaculatus and from 0.11 to 0.85 for D. auripinnis. Early results show that these will be powerful markers for the study of ecological and evolutionary mechanism in this coral reef fish species complex.

Isolation and characterization of 16 microsatellite loci in the humbug damselfish, Dascyllus aruanus (family Pomacentridae).
Here we report on 16 microsatellite loci designed for the damselfish Dascyllus aruanus. All loci were tested on 98 individuals and were polymorphic (seven to 35 alleles). Expected heterozygosity ranged from 0.705 to 0.942. Six loci showed Hardy-Weinberg disequilibrium due to the occurrence of null alleles. Cross-species amplifications conducted within the genus Dascyllus (D. carneus, D. strasbu...
متن کاملSpecies boundaries, populations and colour morphs in the coral reef three-spot damselfish (Dascyllus trimaculatus) species complex.
Coloration patterns of tropical reef fishes is commonly used for taxonomic purposes, yet few studies have focused on the relationship between species boundaries and coloration types. The three-spot damselfish (Dascyllus trimaculatus) species complex comprises four species that vary both in geographical ranges and colour patterns making them an ideal model to study these relationships. We analys...
متن کاملAllopatric divergence and speciation in coral reef fish: the three-spot dascyllus, Dascyllus trimaculatus, species complex.
Long pelagic larval phases and the absence of physical barriers impede rapid speciation and contrast the high diversity observed in marine ecosystems such as coral reefs. In this study, we used the three-spot dascyllus (Dascyllus trimaculatus) species complex to evaluate speciation modes at the spatial scale of the Indo-Pacific. The complex includes four recognized species and four main color m...
متن کاملIsolation and characterization of 13 new microsatellite markers in the triangle mussel (Hyriopsis cumingii)
Microsatellite enriched library of Hyriopsis cumingii was constructed according to the strong affinity between biotin and streptavidin. One hundred clones with foreign inserts were sequenced and 65 clones were screened for usable microsatellites, of which 36 were deemed unique, of sufficient length (more than 8 repeats) and possessed adequate flanking regions for primer designment. Among 36 pri...
