Ants are interesting subjects for studies of evolution of altruism. We developed 13 microsatellite loci in a red wood ant Formica (s. str.) yessensis from random amplified polymorphic DNA fragments to study genetic structure within populations and colonies. Five loci bore two to five alleles in both F. (s. str.) yessensis and F. (s. str.) truncorum and two were also polymorphic in a related species, Polyergus samurai. Results suggest that the loci will be useful in evolutionary studies on Formica and Polyergus species. 相似文献

Seven-band grouper (Epinephelus septemfasciatus) is a commercially important fishery species. Sixty-six microsatellite loci were isolated from a dinucleotide-enriched genomic
library of E. septemfasciatus. Twelve of these loci were polymorphic in a test population with alleles per locus ranging from two to five, and observed
and expected heterozygosities per locus from 0.04 to 1.00 and from 0.28 to 0.76, respectively. Three loci significantly deviated
from Hardy–Weinberg equilibrium and no significant linkage disequilibrium was found between pairs of loci after Bonferroni
correction. Cross-species amplification of these polymorphic microsatellite loci was performed in additional two related species.
These polymorphic microsatellite loci would be useful for investigating genetic resource of E. septemfasciatus and other related species.

Black sea bass (Centropristis striata) is an economically important serranid species. A number of 39 microsatellite loci were isolated from two enriched genomic
library of C. striata. Eleven of these loci were polymorphic in a test population with alleles per locus ranging from 3 to 8, and observed and
expected heterozygosities per locus from 0.26 to 1.00 and from 0.61 to 0.84, respectively. Four loci significantly deviated
from Hardy–Weinberg equilibrium after Bonferroni correction and no significant linkage disequilibrium was found between pairs
of loci. Cross-species amplification of these polymorphic microsatellite loci was performed in additional two related species.
These polymorphic microsatellite loci would be useful for investigating genetic resource of C. striata and other related species. 相似文献

We have isolated 14 polymorphic greater horseshoe bat, Rhinolophus ferrumequinum microsatellite loci. The number of alleles varied from two to 12 in 58 individuals. These loci will be used to assign paternity in order to characterize patterns of breeding and reproductive success in a wild R. ferrumequinum population. Loci were also tested in 17 other bat species. Twelve loci cross‐amplified in other species and three loci were polymorphic in all eight Rhinolophus species tested. 相似文献

Twelve microsatellite markers were isolated from Lolium multiflorum. Allelic variability and cross‐species amplification were assessed on 16 individuals of each of the three grassland species L. multiflorum, Lolium perenne and Festuca pratensis. Cross‐species amplification success was 100% for L. perenne and 83% for F. pratensis. The number of alleles detected ranged from one to 14 with an average of 3.4. While three microsatellite loci were polymorphic in all three species, one marker produced species‐specific alleles in all three species. These microsatellite markers provide a valuable tool for population genetic studies within and among species of the Festuca–Lolium complex. 相似文献

The present study reports the isolation and characterization of eight new polymorphic microsatellite loci from the sexually
deceptive orchid Ophrys fusca. Microsatellites were isolated from two partially enriched genomic libraries using FIASCO (Fast Isolation by AFLP of Sequences
COntaining repeats). Seventy-three loci were screened for primer design and primer pairs corresponding to eight different
loci were selected for microsatellite characterization of two Portuguese populations. Total number of alleles per locus ranged
from 10 to 32. All loci showed a high level of observed heterozygosity (H0) ranging from 0.33 to 1 and were possible to amplify in 16 other species of Ophrys using the same primers.

Yellow grouper (Epinephelus awoara) is a commercially important marine fish species. A dinucleotide-enriched genomic library of E. awoara was constructed using the method of FIASCO. Twelve loci were polymorphic in a test population with alleles per locus ranging
from two to eight, and observed and expected heterozygosities per locus from 0.13 to 1.00 and from 0.20 to 0.86, respectively.
Five loci significantly deviated from Hardy–Weinberg equilibrium and no significant linkage disequilibrium was found between
pairs of loci. Cross-species amplification of these polymorphic microsatellite loci was performed in additional two related
species. These polymorphic microsatellite loci would be useful for investigating genetic diversity of E. awoara and related species.

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

Eleven tetranucleotide microsatellite loci were developed for the Del Norte salamander (Plethodon elongatus). The loci were variably polymorphic, ranging from two to 20 alleles per locus, with expected heterozygosities ranging from 0.07 to 0.86. The loci also amplified in a congener, the Siskiyou Mountain salamander (P. stormi). The microsatellite loci will be used to assess the utility of highly polymorphic markers to assay within‐ and between‐species differentiation between these two closely related species. 相似文献

The animal‐mediated pollination and seed‐dispersal mutualisms of Ficus species give them key roles in tropical ecosystems, but may make them vulnerable to habitat fragmentation. The development of highly polymorphic markers is needed to analyse their genetic diversity and investigate the effects of fragmentation on gene flow. Of thirteen microsatellite loci isolated from Ficus insipida, a monoecious species in French Guiana, eleven were polymorphic (two to six alleles each). High levels of variation were found among loci; expected heterozygosities ranged from 0.151 to 0.715. All markers revealed a broad cross‐species affinity when tested in 23 other Ficus species. 相似文献

The house fly, Musca domestica L., is a cosmopolitan species with a capacity to transmit human pathogens. Here, we report on the development of polymorphic microsatellite loci for house flies and present preliminary results from four house fly subpopulations from Manhattan, Kansas. Twenty‐four microsatellite loci were isolated and characterized using DNA enriched for repeat sequences. Forty individuals from four locations in Kansas were assayed to identify for polymorphic loci. Eight loci were polymorphic with the number of alleles ranging from three to six. 相似文献

A total of 45 microsatellite loci from yellow perch, Perca flavescens, were isolated and characterized. Among the 45 microsatellite loci, 32 had more than two alleles. A wild population of P. flavescens (n = 48) was used to examine the allele range of the microsatellite loci. Mendelian inheritance of alleles was confirmed by examining the amplified products in pair‐mated families. The number of alleles for the 32 polymorphic loci varied from two to 16, and observed heterozygosity ranged between 0.024 (YP79) and 0.979 (YP60). Cross‐species polymorphic amplification in four other Percidae species was successful for 22 loci. 相似文献

Brown seaweeds of the genus Fucus occupy a wide variety of temperate coastal habitats. The genus is evolutionary dynamic with recent radiations to form morphologically distinct taxa. In the brackish Baltic Sea, fucoids are the only perennial canopy‐forming macroalgae. The most northern populations of Fucus occur permanently submerged in extremely low salinity (3–5 psu). These are currently referred to as Fucus vesiculosus L. but are morphologically distinct with a narrow frond without bladders. We report here that a population of this unique morphotype is reproductively isolated from a truly sympatric population of common F. vesiculosus and conclude that the northern morphotype represents a previously undescribed species. We describe Fucus radicans sp. nov., which is attached and dioecious with broadly elliptic receptacles, characterized by a richly branched narrow flat frond (2–5 mm), short thallus (<26 cm), and a high capacity for vegetative recruitment of attached plants. Analysis of five highly polymorphic microsatellite DNA loci showed genetic differentiation between sympatric populations of F. radicans and F. vesiculosus, whereas allopatric populations of the same species revealed a coherent pattern of genetic variation. Sequences of the RUBISCO region in F. radicans were identical to or differing at only one to two dinucleotide positions from those of F. vesiculosus, indicating a recent common origin of the two species. 相似文献

We developed nine polymorphic microsatellite loci for the field vole, Microtus agrestis. The number of alleles ranged from five to 15 and observed heterozygosities ranged from 0.40 to 1.00. We also tested the microsatellite loci for amplification and polymorphism in the congeneric species Microtus arvalis. Five of the nine loci were successfully analysed in this species. The microsatellite markers will be employed in studies of reproductive success and fine‐scale spatial genetic structure. 相似文献

Habitat destruction is causing population decline of many hollow dependent species such as gliding marsupials of the Family Petauridae. Three petaurid species are now listed in some Australian states as either threatened, rare or vulnerable, precipitating a need for information on their basic biology and population structure. We isolated and characterized three polymorphic microsatellite loci from the yellow‐bellied glider (Petaurus australis) and six polymorphic microsatellite loci from the sugar glider (P. breviceps). Per‐locus heterozygosities range from 42%–92%, and cross‐species amplification studies show that between five and seven loci are polymorphic in the two target species as well as a related species P. norfolcensis. 相似文献

The two species of yellow catfish, Horabagrus brachysoma and H. nigricollaris are categorized as ‘endangered’ and ‘critically endangered’ respectively in their wild habitat. Proper knowledge of genetic
structure and variability of these endangered species are highly essential for the management, conservation and improvement
of fish stocks. Therefore, genetic variation and phylogenetic relationships between these species of yellow catfish sampled
from Chalakkudy River in the hot spot of biodiversity-Western Ghats region, Kerala, India were analyzed by using Random amplified
polymorphic DNA (RAPD) and microsatellite markers. 85 RAPD and five microsatellites loci were detected to analyze the genetic
variation and phylogenetic relationships among these species. Out of 85 RAPD loci produced only 52.94% were polymorphic whereas
in microsatellite, all 5 loci were polymorphic (100%). Species-specific RAPD bands were found in both species studied. In
microsatellite, the number of alleles across the five loci ranged from 1 to 8. The observed heterozygosities in H. brachysoma and H. nigricollaris were 0.463 and 0.443, respectively. Here, both RAPD and microsatellite methods reported a low degree of gene diversity and
lack of genetic heterogeneity in both species of Horabagrus which strongly emphasize the need of fishery management, conservation and rehabilitation of these species. 相似文献

The spectacled flying fox, Pteropus conspicillatus, is listed as vulnerable in Australia and is under threat from numerous impacts. Primers to amplify eight co-dominant microsatellite
loci were designed for Pteropus conspicillatus, based on an enriched genomic library. Four loci were monomorphic in this species while the remaining four loci were highly
polymorphic with 16–23 alleles. Two of the four monomorphic loci were found to be polymorphic in Pteropus alecto, a closely related congener. All but one of the six polymorphic loci were in Hardy Weinberg equilibrium. Additionally, six
microsatellite loci isolated for Pteropus rodricensis were tested against individuals of P. conspicillatus with all loci amplifying reliably. These loci will be used to investigate population genetic structure in the vulnerable
spectacled flying fox. 相似文献

Fat greenling (Hexagrammos otakii) is an economocally important marine fish species. Thirtyfive microsatellite loci were isolated from two enriched genomic
library of Hexagrammos otakii. Ten of these loci were polymorphic in a test population with alleles per locus ranging from two to six, and observed and
expected heterozygosities per locus from 0.2581 to 1.0000 and from 0.2892 to 0.7726, respectively. Four loci significantly
deviated from Hardy–Weinberg equilibrium after Bonferroni correction and no significant linkage disequilibrium was found between
pairs of loci. These polymorphic microsatellite loci would be useful for investigating genetic diversity of Hexagrammos otakii. 相似文献
