Ten new polymorphic microsatellites were isolated and characterized in Bactris gasipaes using a microsatellite enrichment protocol and selective hybridization with oligonucleotide probes. The loci are highly polymorphic, with a mean of 14.6 alleles per locus and a mean expected heterozygosity of 0.83 among 62 individuals of the Pampa Hermosa landrace. These microsatellites will be useful for population genetic analysis and germplasm characterization for heart‐of‐palm breeding. 相似文献

A (GA)n microsatellite‐enriched library was constructed and a new set of 18 nuclear simple sequence repeat loci was isolated in Bactris gasipaes var. gasipaes. The loci were found to be highly variable in the target species and readily transferable to related Bactris species as well as to the Astrocaryum and Elaeis genera of the same Cocoeae tribe. These microsatellite resources are made available to study the genetic diversity and gene flow within the Bactris complex for a better understanding of the domestication process of the peach palm and for further Cocoeae genetics. 相似文献

The subfamily Serrasalminae (Characidae, Teleostei) is an endemic Neotropical group of fishes distributed along the Amazon, Paraná‐Paraguay and Orinoco Basins. The pacu (Piaractus mesopotamicus) is found in all major rivers that comprise the Pantanal of Mato Grosso. In order to investigate population genetic structure within the group, an enriched microsatellite library was constructed. Eight polymorphic were loci screened, with an average of 6.5 alleles per locus. Five loci exhibited greater than 60% heterozygosity. Additionally, a high level of cross‐species amplification was obtained. 相似文献

We report the isolation and characterization of polymorphic microsatellite loci for the Siberian flying squirrel Pteromys volans. The seven most useful loci had between six and 11 alleles and expected heterozygosities ranging from 0.477 to 0.866. We also tested the utility of these loci in other squirrel species, northern flying squirrels (Glaucomys sabrinus and G. volans) and the common red squirrel (Sciurus vulgaris). Three of the Siberian flying squirrel loci were polymorphic in other squirrel species, suggesting a limited potential for cross‐species use. 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

We characterized the first microsatellite markers for Gammarus fossarum. Eight loci gave satisfactory amplification patterns in two stream populations (Southern France) with number of alleles ranging from 2 to 10 and expected heterozygosity from 0.076 to 0.857. We performed cross-amplification in two closely related gammarid species, Gammarus pulex and Gammarus orinos. Among the eight tested microsatellite loci, four correctly amplified in G. pulex and three in G. orinos. 相似文献

A total of five polymorphic microsatellites loci from Pseudoplatystoma corruscans were isolated and characterized. A population survey involving 43 specimens resolved a large number of alleles (range seven to eight among loci) and high observed heterozygosity (0.500–0.615), indicating its usefulness in population genetics studies. Cross‐species amplification was successful in four other Pimelodidae species. 相似文献

Solms-laubachia eurycarpa is a medicinal herb endemic to the Hengduan Mountains region of south-central China. We screened a partial genomic library enriched for microsatellites and characterized 10 polymorphic loci for S. eurycarpa. The number of alleles per locus ranged from five to 15, with an average of 9.6. The observed and expected heterozygosities ranged from 0.2 to 0.725 and from 0.585 to 0.871, respectively. Amplification in closely related taxa was successful for most loci. The results indicate significant potential for the utility of these markers in studying the population genetics of S. eurycarpa and related species. 相似文献

We describe isolation and characterization of the first microsatellite loci specifically developed for a very common European passerine bird, the yellowhammer Emberiza citrinella. Nine out of our 10 loci are polymorphic within the species E. citrinella. Number of alleles ranged from two to 21 per locus and observed heterozygosity between 0.20 and 0.91. Four primer pairs also yielded reproducible results in other species of Emberizidae. These loci comprise a set of molecular markers for various applications, from moderately polymorphic loci suitable for population studies to highly polymorphic loci for pedigree analysis in Emberizidae. 相似文献

For studies of population differentiation and range expansion in the seaside goldenrod, Solidago sempervirens, we identified hypervariable molecular markers by screening genomic libraries enriched for microsatellite motifs. We designed primers that reliably amplified nine polymorphic loci. High polymorphism in a population from Delaware Bay, USA suggests that the loci will be useful in population studies. The success of cross‐amplifications in 11 species of Asteraceae varied among loci and did not appear to reflect phylogenetic relationships within Solidago. 相似文献

We developed eight polymorphic nuclear microsatellite markers for the Swiss stone pine (Pinus cembra L.), of which seven may be amplified in a multiplex polymerase chain reaction. Allelic polymorphism across all loci and 40 individuals representing two populations in the Swiss Alps was high (mean = 7.6 alleles). No significant linkage disequlibrium was displayed between pairs of loci. Significant deviation from Hardy–Weinberg equilibrium was revealed at three loci in one population. Cross–amplification was achieved in two related species within the genus (P. sibirica and P. pumila). Thus, the markers may be useful for population genetic studies in these three pine species. They will be applied in ongoing projects on genetic diversity and patterns of gene flow in P. cembra. 相似文献

Ten novel polymorphic microsatellites were isolated from the dace complex (Leuciscus leuciscus), which is a European cyprinid species. Four multiplex polymerase chain reaction sets were optimized in order to genotype 26 polymorphic loci in all, including 16 previously published cyprinid-specific loci. The level of genetic diversity was assessed in 142 dace individuals. We also successfully applied 26 of the microsatellites to 10 related species. These primers thus will be useful to assess population structure of the dace and other cyprinid species, with application for conservation issues and phylogeographical approaches. 相似文献

Isolation and characterization of ten microsatellite loci for Senegal sole (Solea senegalensis Kaup)
VICTORIA FUNES EUGENIA ZUASTI GAETANO CATANESE CARLOS INFANTE MANUEL MANCHADO 《Molecular ecology resources》2004,4(3):339-341
Senegal sole (Solea senegalensis Kaup) is a high‐value marine flatfish exploited in both fisheries and aquaculture. Here we describe the isolation of seven tetranucleotide and three dinucleotide polymorphic microsatellite loci. Characteristics of a captive broodstock and a wild population are described. Three loci displayed a significant departure from Hardy–Weinberg expectations in both populations, suggesting a substantial frequency of null alleles. The remaining seven loci were found to be in equilibrium in the wild population, whereas only four of them were in the cultured population. Cross‐species amplification was successful for three loci in other five flatfishes. 相似文献

We developed a set of di‐ and tetranucleotide microsatellite markers for the Alpine newt, Triturus alpestris. Polymorphism as detected in 39 individuals ranged from 3 to 32 alleles at a locus. Cross‐priming with samples of five other Triturus species showed extremely poor levels of cross‐species utility. Still, these markers are suitable for studies of inter‐ and intrapopulation genetic diversity in the focal species. 相似文献

Here we describe 32 di‐, tri‐ and tetranucleotide microsatellite loci isolated by PIMA, a polymerase chain reaction (PCR)‐based procedure, for the common snook (Centropomus undecimalis). Five loci were monomorphic, and the remaining loci averaged 6.7 alleles per locus in a sample of 45 common snook. For polymorphic loci, expected heterozygosities ranged from 0.02 to 0.91 (mean = 0.538). Significant departures from Hardy–Weinberg equilibrium expectations occurred in two loci. Exact tests for genotype disequilibrium gave evidence for linkage at one pair of loci. Many cross‐species primer assays yielded PCR fragments of the expected size for 11 species of Centropomus and two species of the confamilial genus Lates. 相似文献

We report the development of three new microsatellites and four transferred across‐species for fork‐marked lemurs (Phaner furcifer). Two markers were isolated from Cheirogaleus medius and one from Microcebus murinus. The transferred markers also originate from Cheirogaleus medius and Microcebus murinus. The seven markers were tested on 30 individuals of Phaner furcifer and have proven to be useful for inclusion and exclusion of potential parents. The markers presented here are the first published for application on Phaner furcifer. 相似文献

The Fucaceae is a family of brown seaweeds that dominate and frequently co‐occur on North Atlantic rocky shores. We developed nine polymorphic microsatellite markers for the fucoid seaweeds Fucus vesiculosus, F. serratus and Ascophyllum nodosum using a combined, enriched library. Six of these loci were polymorphic in at least two species, showing from two to eight alleles with heterozygosities ranging from 0.41 to 0.85. Loci were also tested on F. spiralis, revealing five polymorphic microsatellite loci in this species. 相似文献

Seven polymorphic microsatellite loci were identified for woolly monkeys (Lagothrix lagotricha) from an ‘enriched’ genomic library. For a wild population of 66 animals, these markers averaged over 10 alleles per locus and provided a combined probability for excluding a random individual from parentage of over 98%. These loci were screened in up to 13 other genera of New World monkeys, and many were variable in multiple taxa. Few other platyrrhine‐specific microsatellite markers have been identified; thus, these loci should prove valuable for studying the population genetic structure and mating system not just of Lagothrix but also of other neotropical primates. 相似文献

The large bent-wing bat, Miniopterus schreibersii (Kuhl 1819), has a long history of taxonomic uncertainty and many populations are known to be in a state of decline. Microsatellite loci were developed for the taxonomic and population genetic assessment of the Australian complex of this species. Of the 33 primer sets designed for this research, seven (21%) were deemed suitably polymorphic for population-level analyses of the Australian taxa, with five (71%) of these loci revealing moderate to high levels of polymorphism (PIC = 0.56 to 0.91). The cross-taxa utility of the M. schreibersii microsatellite markers was assessed in the microbat (Chiroptera) family Miniopteridae. Sub-species and species covering the Miniopteridae's global distribution (with the exception of the Middle East) were selected, numbering 25 taxa in total. Amplification was successful for 26 loci, of which 20 (77%) were polymorphic. High cross-taxa utility of markers was observed with amplification achieved for all taxa for between four (20%) and 20 (100%) loci, and polymorphism was considered moderate to high (PIC = 0.47-0.91) for 12 (60%) of these loci. The high cross-taxa utility of the microsatellites reported herein reveal versatile and cost-effective molecular markers, contributing an important genetic resource for the research and conservation of Miniopteridae species worldwide. 相似文献
