We report the development of 14 polymorphic microsatellite markers for the black‐tailed prairie dog, Cynomys ludovicianus. The number of alleles per locus ranges from three to 11, and the observed heterozygosity ranges from 0.37500 to 1.0000. These markers will benefit studies of landscape effects on prairie dog migration, disease dynamics, and conservation efforts. 相似文献

We developed a set of nine polymorphic microsatellite loci for black‐breasted wood‐quail, Odontophorus leucolaemus. We screened 50 individuals from Monteverde, Puntarenas Province, Costa Rica and found that locus‐specific allelic diversity ranges from two to 15 alleles (mean 10.2) and observed heterozygosity ranges from 0.24 to 0.96 (mean 0.78). These markers appear to be useful in other members of the Odontophorus genus. 相似文献

Eriocheir sinensis has higher commercial value as food source than any other species of Eriocheir in China. To protect its germplasm resources and evaluate impact on local ecology, molecular tools to characterize the population structure and identify kinships from different water systems are highly needed. We have newly identified a set of 18 microsatellite markers with the observed number of alleles at each locus ranges from 8 to 30, the observed heterozygosity ranges from 0.140 to 0.900. These newly isolated markers increase the available molecular resources that can be used to analyse population structure of Chinese mitten crab. 相似文献

We describe primer sequences for five microsatellite markers in Cardiocondyla elegans, an ant species with ergatoid males. Polymorphism of these loci was investigated using 236 individuals from 22 colonies from four locations. The microsatellites are dinucleotide repeats with four to 16 alleles, and the observed heterozygosity ranges from 0.244 to 0.720. We characterized these markers for the study of the population as well as the social structure of colonies. 相似文献

We have isolated 16 polymorphic microsatellite markers for the green‐eyed tree frog, Litoria genimaculata, from genomic libraries enriched for (AAGG)n and (AAAG)n repetitive elements. The number of alleles ranges from four to 14 per locus with the observed heterozygosity ranging from 0.36 to 1.00. These markers will be useful for analysis of questions concerning population genetic structure and speciation. 相似文献

We isolated 12 polymorphic microsatellite markers for the grey‐headed robin Poecilodryas albispecularis from genomic libraries enriched for (AAGG)n and (AACC)n repetitive elements and characterized them in 12 individuals. The number of alleles ranges from three to nine per locus with the observed heterozygosity ranging from 0.33 to 0.90. These markers will be useful for analysis of questions concerning population genetic structure and testing models of speciation. 相似文献

Fusarium poae is a pathogen of increasing importance within the disease complex Fusarium head blight (FHB). Eleven microsatellite markers were developed, and 72 F. poae strains from Switzerland and other countries were used to assess the level of marker polymorphism. The number of alleles for each of the markers ranged from 4 to 15, and the average gene diversity was 0.62, ranging from 0.25 to 0.84. Using these novel markers, 44 genotypes could be differentiated among all F. poae strains. Two genotypes were represented by nine and ten strains, respectively, deriving from distinct geographic areas within Switzerland and indicating a potential selection advantage. Four markers were F. poae‐specific, whereas seven markers also yielded amplification products in one to four strains of five other Fusarium species. Of the latter, five markers revealed F. poae‐specific allele size ranges. Hence, these microsatellite markers could be used both for FHB species differentiation and for intra‐specific distinction of F. poae strains. 相似文献

Microsatellites are codominant and highly polymorphic genetic markers. They are widely used in studying parentage and reproductive success in many insect species. We developed six microsatellite markers in Pissodes storbi. The number of alleles per locus ranges from 5 to 16 alleles, with a mean number of 10. The high allelic diversity observed in this study showed that they could be useful in the study of parentage and reproductive success in P. strobi. 相似文献

Anopheles culicifacies, an important vector in the Indian subcontinent is a complex of five sibling species of which four are vectors. We describe the isolation of 31 microsatellite markers from the recently recognized isomorphic species A of which 13 were characterized in sympatric populations of Anopheles culicifacies isomorphic species A and B. The allele frequencies ranges from two to 12 in species A and two to seven in species B. Species A being a vector, and that these markers can be used in closely related species, makes the isolation of these markers important to study population structure of all sibling species in this complex. 相似文献

Eighteen polymorphic microsatellite markers were developed for the greater long-tailed hamster (Tscherskia triton), a species of interest across northern China. The expected heterozygosity at these loci ranges from 0.6444 to 0.9196, with
the observed allele numbers varying from 6 to 23. All loci conformed to Hardy–Weinberg equilibrium and no pair displayed linkage
disequilibrium after a Bonferroni correction. These markers should prove useful for studies of population structure, kinship,
social structure and other interesting issues of this important species. 相似文献

The five recognized endemic pamphagid species (Orthoptera) of the Canary Islands have restricted and fragmented ranges due to habitat decline. Seven polymorphic microsatellite markers have been developed for Acrostira tamarani, and the performance of primer pairs amplifying these loci in related taxa has been tested. The number of alleles in A. tamarani samples taken from two distant localities in the island of Gran Canaria ranged from two to eight per locus. Observed heterozygosities were from 0.151 to 0.559. Up to four primer pairs amplified in related species with moderate heterozigosities (maximum of 0.687 and 10 alleles for Ata67 locus in Purpuraria erna). These markers could be useful tools to study the population structure and management of endemic threatened pamphagids of the Canary archipelago. 相似文献

The role of geography and ecology in shaping repeated patterns of morphological and genetic differentiation between European minnows (Phoxinus phoxinus) from the Pyrenees and the Alps 下载免费PDF全文

Neutral and selective processes can drive repeated patterns of evolution in different groups of populations experiencing similar ecological gradients. In this paper, we used a combination of nuclear and mitochondrial DNA markers, as well as geometric morphometrics, to investigate repeated patterns of morphological and genetic divergence of European minnows in two mountain ranges: the Pyrenees and the Alps. European minnows (Phoxinus phoxinus) are cyprinid fish inhabiting most freshwater bodies in Europe, including those in different mountain ranges that could act as major geographical barriers to gene flow. We explored patterns of P. phoxinus phenotypic and genetic diversification along a gradient of altitude common to the two mountain ranges, and tested for isolation by distance (IBD), isolation by environment (IBE) and isolation by adaptation (IBA). The results indicated that populations from the Pyrenees and the Alps belong to two well differentiated, reciprocally monophyletic mtDNA lineages. Substantial genetic differentiation due to geographical isolation within and between populations from the Pyrenees and the Alps was also found using rapidly evolving AFLPs markers (isolation by distance or IBD), as well as morphological differences between mountain ranges. Also, morphology varied strongly with elevation and so did genetic differentiation to a lower extent. Despite moderate evidence for IBE and IBA, and therefore of repeated evolution, substantial population heterogeneity was found at the genetic level, suggesting that selection and population specific genetic drift act in concert to affect genetic divergence. 相似文献

Based on biochemical markers, we studied the nutrition ranges of populations of Dreissena polymorpha and Dreissena bugensis mussels that inhabit the Volga reach of the Rybinsk reservoir and differ in the long-term population dynamics. Features of the nutrition ranges of mussels are regarded as the probable cause of changes in the number of mollusca. 相似文献

The Humboldt penguin (Spheniscus humboldti) was once very common throughout its range along the coast of Peru and Chile. Today, listed as endangered, it is crucial to gain an understanding of gene flow and levels of genetic variation between breeding colonies to protect this species effectively. We developed seven microsatellite primers to investigate gene flow and population structure among four colonies. Locus‐specific allelic diversity ranges from five to 11 alleles and observed heterozygosity ranges from 0.50 to 0.88. These markers cross‐amplify in eight penguin species over five genera. 相似文献

Twelve polymorphic microsatellite loci were isolated and characterized from an AC‐enriched genomic library of Nothotsuga longibracteata. The average allele number of these microsatellites was 8.3 per locus, ranging from two to 13. The ranges of observed and expected heterozygosities were 0.03–0.97 and 0.09–0.88, respectively. These polymorphic markers provide useful tools for the study of evolutionary history and conservation genetics of N. longibracteata. 相似文献

We have isolated 18 polymorphic microsatellite loci for Cophixalus ornatus from genomic libraries enriched for (AAAG)n, (AACC)n and (AAGG)n repetitive elements. The number of alleles ranges from five to 22 per locus with the observed heterozygosity ranging from 0.10 to 0.92. These markers will be useful for the analysis of population structure in C. ornatus and testing alternative models of speciation. 相似文献

We have developed seven microsatellite primers for the solitary wasp Ancistrocerus adiabatus. The number of alleles per locus ranged from three to 14. The markers were developed to study population structure, inbreeding and sex determination of A. adiabatus. For each locus, we genotyped 30 female wasps collected from Southwest Michigan. The observed heterozygosity ranges from 0.067 to 0.933. We have also determined that primers for these microsatellite loci amplify in three other species in the genus: Ancistrocerus antilope, Ancistrocerus catskill, and Ancistrocerus campesterus. 相似文献

Ipecac (Psychotria ipecacuanha) is a perennial, medicinal herb that grows in the understory of semi-deciduous tropical forests in the Neotropics. Ipecacs
present a widely disjunct distribution, with two of its three ranges occurring in Brazil. The Amazonian populations are at
least 1600 km from the nearest Atlantic populations. This work used ISSR markers to compare the genetic diversity and structure
of populations from the two Brazilian ranges. Lower genetic diversity in Amazon populations (P = 60.11%, Hs = 0.18) and higher
genetic diversity in Atlantic populations (P = 73.94%, Hs = 0.20) were detected. Differentiation between ranges were high
(θ
B = 0.6838, GST-B = 0.6665). AMOVA revealed that 65.3% of the total molecular variance can be attributed to regional differences between
the two ranges. Principal coordinate analyses and cluster analyses organized ipecacs at either individual or population level
into two exclusive groups that correspond each to one of the two disjunct ranges, without exception. The results do not support
a scenario that postulates human-mediated, long-distance dispersal events as a plausible origin for the distribution of the
Brazilian ipecacs, but indicate geographic isolation as a long-standing barrier to genetic exchange and connectivity among
populations from different ranges. Conservation implications are discussed. 相似文献

Callipepla californica and C. gambelii are sibling species of quail that hybridize throughout Southern California where their ranges overlap. We developed seven highly polymorphic microsatellite markers that will be used to assess introgression between these species. Numbers of alleles ranged in C. californica from seven to 24 and in C. gambelii from five to 18, with high expected levels of heterozygosity in both species. Alleles exclusive to each species are present at most loci. 相似文献

RAPD (Random Amplified Polymorphic DNA) markers were used to identify genets within a weed infestation of Arrhenatherum elatius ssp bulbosum (“onion couch”). Three selected primers could discriminate between 18 sexually-derived plants of A. elatius ssp. elatius. Using these primers, RAPD phenotypes were obtained for ramets of ssp. bulbosum from a population of unknown sexual derivation, i.e. predominantly sexual or vegetative. Thirty three RAPD phenotypes were observed amongst 65 plants. Ramets with identical RAPD phenotypes were termed “genets”. Some genets of ssp. bulbosum were found in localised patches, whereas others had much wider ranges, indicating long-distance dispersal by farm machinery. RAPD markers provide a useful tool for discriminating between genets within an established plant population. 相似文献
