Eleven polymorphic microsatellite loci were obtained from a GA enriched genomic library, constructed from DNA of buck’s‐horn plantain (Plantago coronopus). The microsatellite loci were tested on 24 genotypes. These plants were collected from meadows along the coast, located on 11 sites ranging from the southwest to the northeast of the Netherlands. In this set of plants the isolated microsatellites were highly polymorphic with 3–24 alleles per locus and a maximum observed heterozygosity of 0.91. Some of the microsatellite loci also showed amplification in two other plantain species (P. lanceolata and P. maritima). 相似文献

Five microsatellite loci of Helicoverpa armigera were isolated from a partial genomic library screened by oligonucleotide probes. Primers were designed to detect allelic variability and heterozygosity in 60 individuals collected from different host species. All loci were found to be polymorphic, have 8–11 alleles with expected heterozygosity ranging from 0.81 to 0.88. Our results indicate that the five microsatellite loci could provide valuable markers for population genetic and ecological studies of the cotton bollworm. 相似文献

The endangered vermilion darter (Etheostoma chermocki) is endemic to the Black Warrior River system in the Mobile Basin in Alabama. Restoration and conservation of this species require an understanding of its population genetic structure, which can be characterized using microsatellite DNA. Nine microsatellite loci were developed; eight loci were polymorphic. Although observed heterozygosity was lower than expected heterozygosity in most polymorphic loci, only one locus showed significant deviation from Hardy–Weinberg equilibrium. These nine markers were tested in an additional 24 species of Etheostoma and appear to have sufficient allelic variation to be useful in studies of population genetic structure. 相似文献

This paper reports the development of microsatellite primers for Nelumbo nucifera Gaerten. By screening genomic libraries enriched with 10 kinds of probes, Seventeen polymorphic loci were isolated and primers
were designed. Polymorphism of these 17 loci was assessed in 24 individuals. All the 17 loci are polymorphic and the number
of alleles ranged from two to seven. Observed heterozygosity and expected heterozygosity ranged from 0.0000 to 0.9176 and
from 0.2837 to 0.7917 respectively. These microsatellite loci should be useful for studying the genetic diversity of N. nucifera. 相似文献

We report ten microsatellite loci in the Emei moustache toads, Leptobrachium boringii. Markers were obtained by screening a genomic library enriched for microsatellite motifs. Twenty-four individuals from one
breeding site were examined and ten loci were polymorphic. The number of alleles per locus ranged from 3–9 with an average
of 6.3/locus. The expected heterozygosity and observed heterozygosity ranged from 0.3874 to 0.8432, and from 0.4583 to 0.9167,
respectively. Cross-species amplification was tested in a closely related species L. leishanensis. These markers will be useful in future studies on characterizing the mating system of the species. 相似文献

Eleven polymorphic microsatellite loci were characterized for the endangered conifer Taxus yunnanensis. Eight loci were isolated through SSR-anchored PCR, one locus was developed by cross-species amplification tests, while the
last two loci were obtained from cross-species microsatellite sequences available in GenBank. Variability of these markers
was tested in 48 individuals collected from its main distribution range in Southwest China. The number of alleles per locus
ranged from 2 to 9, and the observed and expected heterozygosity varied from 0.000 to 0.625 and from 0.062 to 0.853, respectively.
Ten of these eleven loci were significantly deviated from Hardy–Weinberg expectation, except TS07 which showed a distinct
heterozygote excess. The availability of these new polymorphic microsatellite markers will provide an ideal marker system
for detailed population genetics studies in T. yunnanensis and potentially also for closely related species. 相似文献

The kakerori (Pomarea dimidiata) is an endangered forest bird in the Cook Islands, South Pacific. We have developed 10 microsatellite markers using kakerori
feathers as the DNA source. Seven of these loci were found to be polymorphic in 42 individuals examined. The number of alleles
per locus in the polymorphic loci varied from 3 to 5. Observed and expected heterozygosity ranges were 0.57–0.74 and 0.50–0.74,
respectively. All loci isolated conformed to Hardy–Weinberg equilibrium expectations. We believe these loci will be useful
in studying kakerori conservation genetics, and our success in developing microsatellite markers from feather samples will
encourage the use of less invasive sample sources in microsatellite isolation studies. 相似文献

Seven single locus microsatellite markers were characterized in Malaysian giant freshwater prawn, Macrobrachium rosenbergii from an enriched genomic library Primer pairs were designed to flank the repeat sequences and the loci characterized for
this species. The bands resulting from the PCR amplifications of these eight microsatellite loci were polymorphic with the
number of alleles ranging from 8 to 26 alleles per locus, whereas the observed heterozygosity ranged from 0.0641 to 0.6564.
These newly developed microsatellite markers should prove to be useful for population studies and in the management of genetic
variations in broodstocks of freshwater prawn, M. rosenbergii. 相似文献

We developed microsatellite loci for the southern pine beetle (Dendroctonus frontalis). Twelve microsatellite loci were identified. Eight loci were polymorphic and sufficiently variable in 62 individuals (expected heterozygosity ranged from 0.707 to 0.880) to investigate population structure. All loci conformed to HWE except Dfr‐14, which showed heterozygote excess, and no two loci deviated from linkage equilibrium. The loci were tested for cross‐species amplification in four species of Dendroctonus (D. valens, D. terebrans, D. brevicomis, and D. ponderosae). Seven loci were polymorphic in at least one of the species tested. 相似文献

Since the number and range of Asiatic black bear (Ursus thibetanus) are declining due to habitat loss and illegal trade, it is essential to take effective actions to reinforce the conservation
of the remaining bear populations. In order to aid such conservation efforts, we developed 12 novel polymorphic microsatellite
loci of Asiatic black bear from genomic DNA-enriched libraries in this paper. The number of alleles per locus in 24 individuals
ranged from 3 to 10, the average observed heterozygosity per locus from 0.214 to 0.950, and the average expected heterozygosity
per locus from 0.243 to 0.891. Eight loci followed Hardy–Weinberg expectations after Bonferroni correction for multiple comparisons.
No significant linkage association was found among all these loci. The 12 polymorphic microsatellite loci will be helpful
to the conservation of the Asiatic black bear. 相似文献

The blue mussel Mytilus trossulus occurs in the Pacific and in the North Atlantic. We developed and characterized six microsatellite loci for Baltic M. trossulus. Seventeen microsatellite loci were screened, of which six were polymorphic. The number of alleles among 50 individuals ranged
from 3 to 13 and the observed and expected heterozygosity were 0.09–0.46 and 0.34–0.86, respectively. The loci were also tested
for cross amplification in M. edulis, in which four of the six microsatellite loci were successfully amplified. 相似文献

Here we report development and characterization of 14 polymorphic microsatellite loci from Sebastes schlegel. Polymorphism at these loci revealed from 3 to 23 alleles. The observed heterozygosity ranged from 0.34 to 1.00, and the
expected heterozygosity ranged from 0.31 to 0.95. No linkage disequibrium was found. Two loci were significantly deviated
from HWE (P < 0.01). The 14 loci were also surveyed in four other Sebastes species and 12 loci successfully amplified, where allelic diversity ranged from highly polymorphic to monomorphic. These
results demonstrate these microsatellite markers can be used for the study of intra- and inter-specific genetic diversity. 相似文献

Nine polymorphic microsatellite loci were identified in the tropical plant Vasconcellea ×heilbornii and used to estimate allelic diversity in two populations of southern Ecuador. Allelic richness ranged from two to five alleles, observed heterozygosity ranged from 0.150 to 0.947 and expected heterozygosity ranged from 0.186 to 0.701. Most of these markers also amplified microsatellite loci in two other Vasconcellea species (Vasconcellea stipulata and Vasconcellea cundinamarcensis). Hence, these markers will be useful for population genetic analysis and the evaluation of genetic diversity and gene flow in these species. 相似文献

Fourteen polymorphic microsatellite markers were isolated from the entomopathogenic fungus, Metarhizium anisopliae, based on enriched genomic libraries. In order to assess allelic variability, the microsatellite loci were analysed in a collection of 34 isolates sampled from across Switzerland. The number of detected alleles in 14 loci ranged from two to eight and expected heterozygosity from 0.265 to 0.808. Because of the high expected heterozygosity, the 14 microsatellite loci are very useful for ecological studies and analysis of population diversity, and to identifying, monitoring, and tracking M. anisopliae strains applied as biological control agents. 相似文献

Forty microsatellite markers were developed from a (CA)n enrichment library created from the DNA of southern catfish (Silurus meriaionalis). Also, the population structure of northern sheatfish (Silurus soldatovi) was examined by 24 microsatellite loci. They are polymorphic in at least one of the two geographically distant populations sampled from the Heilongjiang River and the Songhuajiang River in North China, respectively. Unbiased expected heterozygosity levels varied from 0.435 to 0.946 and number of alleles per locus varied from three to 20. Results indicated that these microsatellite loci were highly polymorphic and could be used as genetic markers. 相似文献

Sixteen polymorphic microsatellite loci were isolated from an enriched genomic library of Ussuri cisco, Coregonus usssruensi. The polymorphism of these loci was tested on a population of 30 individuals captured from Heilongjiang River. The number
of observed alleles per locus ranged from 3 to 18. The expected and observed heterozygosity values ranged from 0.126 to 0.919
and 0.133 to 0.833, respectively. Five loci significantly deviated from Hardy–Weinberg equilibrium after Bonferroni correction.
No significant linkage disequilibrium was detected. These polymorphic markers will be used to assess population structure
in Ussuri cisco. 相似文献

Eight polymorphic di‐ and trinucleotide microsatellite loci suitable for population genetic analysis were developed in Locusta migratoria from a partial phagemid genomic library enriched for microsatellite inserts. The expected heterozygosity at these loci ranges from 0.45 to 0.97, with the observed allele numbers varying between nine and 45. The overall microsatellite cloning efficiency in L. migratoria is 14%, suggesting that in migratory locusts, microsatellite sequences are abundant and should provide a valuable and easily accessible source of nuclear markers for genetic studies. These microsatellite loci were highly Locusta‐specific, with only very limited cross‐species applicability. 相似文献

Five new polymorphic microsatellite loci were developed for the coral reef damselfish Pomacentrus amboinensis. Twenty-four individuals from two Great Barrier Reef populations were genotyped at the five loci, with numbers of alleles
per locus ranging from 6–23 and observed heterozygosity between 0.42–0.92. In addition, the cross-species testing of six primers
developed for Stegastes partitus revealed one primer (SpGATA40) that was also polymorphic for P. amboinensis. Due to high levels of polymorphism (≥14 alleles) in at least four of the six loci and a high proportion of tetranucleotide
repeats, these microsatellite markers should be useful for parentage assignment as well as other investigations of individual
relatedness. 相似文献

Black locust (Robinia pseudoacacia) is an economically and ecologically important tree species in the world. We isolated seven polymorphic microsatellite loci from R. pseudoacacia using a dual‐suppression‐PCR technique. These loci provided microsatellite markers with high polymorphism ranging from three to 12 alleles per locus and expected heterozygosity between 0.538 and 0.944. The markers are now available for more detailed investigation of population genetic structure and pollen and seed dispersal. 相似文献

In this study we characterized 10 polymorphic microsatellite markers for the land snail Cylindrus obtusus, an endemism of the Austrian Alps with a distribution in isolated populations above approximately 1,600 m. The microsatellite
loci were analyzed in 44 individuals from two populations. Number of alleles per locus ranged between two and eight. Observed
heterozygosity ranged between 0.00 and 1.00, and expected heterozygosity between 0.09 and 0.72. No significant linkage disequilibrium
was found between pairs of loci. One of the sampled populations (Dachstein) showed no deviation from Hardy–Weinberg equilibrium
and no presence of null alleles, whereas the other one (Schneeberg) did. These diverging results probably reflect differences
in population structure rather than characteristics of the microsatellite loci and underline the usefulness of these markers
for studying genetic diversity, population structure and differentiation in C. obtusus. 相似文献
