The lance‐tailed manakin (Chiroxiphia lanceolata) is a lek‐breeding bird from Central America in which males court females with complex cooperative displays. To resolve detailed patterns of paternity in the wild, we isolated and characterized 12 novel microsatellite loci in this species. Eleven of these loci were polymorphic (five to 14 alleles), with observed heterozygosities ranging from 0.36 to 0.87 (N = 574 individuals). We tested for linkage disequilibrium using randomized subsamples of adults to control for known family structure among long‐lived and sedentary individuals. These loci will be valuable in resolving paternity among many candidate fathers in this species.  相似文献

Microsatellite loci were developed for the giant white‐tailed rat (Uromys caudimaculatus) to aid in assigning paternity and to subsequently investigate their mating system and sex‐biased dispersal characteristics. Twenty‐two primer sets were originally developed and of these, 11 were polymorphic with between five and 10 alleles per locus. In addition, two primer sets designed for Hydromys chyrsogaster also amplified in this species despite an evolutionary divergence of 15 million years (Myr).  相似文献

We designed primers for amplifying 11 polymorphic microsatellite loci in the blue manakin, Chiroxiphia caudata, a neotropical passerine bird which inhabits a critically endangered tropical ecosystem, the Brazilian Atlantic forest. Based on genotypes from 24 individuals from a single population, we detected between four and 22 alleles per locus with observed heterozygosities ranging from 0.54 to 0.92. These highly variable loci will be useful for determining levels of population differentiation and assessing the impact of habitat fragmentation on levels of genetic variation in isolated populations of these birds.  相似文献

Superb starlings (Lamprotornis superbus) are separate nesting plural cooperative breeders endemic to East Africa that show high levels of reproductive conflict and low reproductive skew. I isolated 31 polymorphic microsatellite loci from the superb starling genome and characterized them in approximately 31 individuals. The numbers of alleles per locus ranged from two to 16 and observed heterozygosities ranged from 0.03 to 0.88. Many of these loci amplified in other passerine species including the European starling, Sturnus vulgaris, and a variety of other starlings and mockingbirds.  相似文献

The genus Plantago is particularly interesting for evolutionary studies because of its wide range of mating systems. We have developed primers for five highly polymorphic microsatellite loci isolated from P. lanceolata. All five loci amplified and were polymorphic in the two populations examined, Lowsteads Beach in the United Kingdom and Duke in the United States. These new markers will allow a comparison of population structure between the outcrossing species P. lanceolata, and the highly selfing species P. major.  相似文献

Twenty‐six polymorphic microsatellite markers were isolated from (AC)n and (AG)n microsatellite‐enhanced genomic libraries of the gray, short‐tailed opossum Monodelphis domestica. All 26 loci showed high allelic diversity, with allele numbers ranging from five to 11 in a subset of 35 animals. Normal Mendelian inheritance was confirmed for 24 loci by analysing allelic segregation in 10, two‐generation, families. Non‐amplifying (null) alleles were detected at two loci, which we recommend be used only if pedigree data are available. We conclude that all of these microsatellite markers would be useful for quantitative trait locus mapping and population genetic studies.  相似文献

We report the isolation and characterization of 17 polymorphic microsatellite loci in the North American raccoon (Procyon lotor). These loci exhibit high levels of allelic diversity, with between four and 13 alleles per locus, and heterozygosity, with observed values of 0.500-1.000 in a sample of 20 individuals. All genotypes conformed to Hardy-Weinberg expectations and there were no instances of linkage disequilibrium detected.  相似文献

We isolated 10 microsatellite loci for Jacaranda copaia for direct measurement of seed and pollen movement within the 50 ha Forest Dynamics Plot on Barro Colorado Island, Panama, and for studies of population genetic structure and gene flow across the Isthmus of Panama. Enriched repeat libraries were screened for microsatellite repeats and polymorphic primer pairs were developed. A total of 110 adult individuals were screened for allelic diversity and loci showed high levels of heterozygosity. These loci show both high maternal and paternal exclusion probabilities.  相似文献

Tuber spp. are fungi that establish symbiosis with several trees and shrubs. Some of these fungal species produce edible ascomata, also known as truffles, which are highly appreciated for their taste and odour. We isolated and characterized eight polymorphic microsatellite loci from Tuber magnatum, the finest white truffle species, and assessed their variability in 370 individuals collected from all over the species range of distribution. Although two to 18 alleles per locus were found, no heterozygous individuals were observed. The availability of simple sequence repeat loci provides valuable tools for assessment of the genetic structure and population dynamics in this species.  相似文献

To investigate the mating system of northern flickers (Colaptes auratus), we developed primers for 14 microsatellite loci and screened them in 68 unrelated adults and their offspring. All markers were highly polymorphic with 9 to +36 alleles per locus. One marker was Z‐chromosome linked; one marker exceeded the size standard range and could not be analysed further. We checked the other 12 markers for Mendelian inheritance in 36 broods for which the social parents were known. Seven markers showed evidence for the presence of null alleles, and three of those showed significant deviation from Hardy–Weinberg equilibrium. Markers were generally unlinked.  相似文献

We report on the development of nine polymorphic microsatellite loci in nurse shark (Ginglymostoma cirratum) using a combination of enriched and unenriched subgenomic libraries. Based on the small percentage of positive clones in the unenriched library (0.4%) it appears that microsatellites are very scarce in nurse shark genomes. Numbers of alleles at polymorphic loci ranged from two to 15; observed heterozygosity ranged from 0.17 to 0.90. We expect these loci to be useful for studies of breeding structure and paternity.  相似文献

Wilsonia backhousei is a clonal saltmarsh plant restricted to the southern latitudes of Australasia and threatened in New South Wales. We have identified eight informative microsatellite loci in the species from (AG)n‐ and (AC)n‐enriched libraries. In 48 samples from two populations we detected an average of five alleles per locus (range 2–8, average HE = 0.45), of which 72% were unique to one population or the other. Six of the eight loci were also amplifiable in Wilsonia rotundifolia under the same reaction conditions. The markers will be excellent tools for use in the management and conservation of both species.  相似文献

We describe seven polymorphic microsatellite loci for the mallard (Anas platyrhynchos). The microsatellites presented here are highly polymorphic, with on average 12 alleles in a sample of 15 presumably unrelated individuals. Therefore, they enable detailed parentage analysis in wild mallard populations, and can be used to answer many intriguing questions in behavioural ecology and evolutionary biology.  相似文献

Laelia speciosa is an endangered epiphytic orchid endemic to central Mexico. Here, we report on the development of 14 perfect and imperfect microsatellite repeat loci for this species. Numbers of alleles ranged from two to 16 and levels of observed heterozygosities among the 14 loci ranged from 0.28 to 1.00 across two widely divergent populations. All loci were also tested for cross-amplification in four other Laelia species and other selected genera of the subtribe Laeliinae.  相似文献

Microsatellite flanking region sequences may provide phylogenetically useful information. We isolated 13 polymorphic microsatellite loci from two species, Clusia minor (five loci) and Clusia nemorosa (eight loci), to aid in the determination of phylogenetic relationships within the genus Clusia. Eleven loci amplified across all 17 Clusia species tested, while two loci amplified in 10 out of 17 species. The extensive cross‐species amplification suggests that these loci may be useful for an examination of phylogenetic relationships in this genus.  相似文献

Studies of tropical plant population structure and gene flow are needed to estimate genetic repercussions of tropical deforestation. Twelve microsatellite loci were isolated for Corythophora alta (Lecythidaceae), a canopy tree at the Biological Dynamics of Forest Fragments Project, near Manaus, Brazil. These microsatellites will be used to estimate population structure and infer seed paternity. Loci were isolated with a subtractive hybridization method. Loci averaged 10.7 alleles per locus with high levels of heterozygosity. Four loci had significant deficits and one locus had a significant excess of heterozygotes compared to Hardy–Weinberg expectations. Many loci had high average probabilities of paternity exclusion.  相似文献

Quantifying genetic kinship and parentage is critical to understanding the adaptive consequences of sociality. To measure fitness in a species with variable group structure, we isolated 14 microsatellite loci from Octodon degus, a semi-fossorial rodent endemic to Chile. The number of alleles per locus ranged from four to 14. Thirteen loci were in Hardy-Weinberg proportions, with values of observed heterozygosity ranging from 0.550 to 0.950. These markers provide the basis for future studies of the direct fitness consequences of sociality in O. degus.  相似文献

Six dinucleotide, three trinucleotide and seven tetranucleotide microsatellite loci developed for the great tit Parus major are presented. Thirty individual birds were screened at each locus. Loci were polymorphic (four to 19 alleles per locus). These markers provide a system to study paternity, genetic diversity in natural populations, gene flow, dispersal and inbreeding.  相似文献

We describe 18 microsatellite markers isolated in the cooperatively breeding chestnut‐crowned babbler (Pomatostomus ruficeps). The number of alleles ranged from seven to 16 per locus (mean Na = 10.4 ± 0.54 SE) and the expected heterozygosity ranged from 0.732 to 0.889 (mean HE = 0.836 ± 0.01 SE). Three of the 18 loci exhibited significant heterozygote deficiency, but the remaining 15 will be used to analyse population genetic structure and the mating system of this highly social species.  相似文献
