Identification of microsatellite loci from Epimedium koreanum and cross‐species amplification in four species of Epimedium (Berberidaceae)

Nineteen polymorphic microsatellite markers were isolated and characterized from a trinucleotide enriched partial genomic library of Epimedium koreanum. The average allele number of these microsatellites was 5.9 per locus, ranging from two to 11. The observed heterozygosity (H_O) and expected heterozygosity (H_E) at the population level were 0.00–0.90 and 0.12–0.90, respectively. In addition, the results of cross‐species amplification of this set of microsatellite markers in four closely related Epimedium species, E. brevicornum, E. sagittatum, E. pubescens and E. wushanense, revealed that these microsatellite markers were useful for population genetic structure evaluation and genotype analysis of major Epimedium species that have been used as traditional Chinese medicines.     

Characterization of microsatellite loci in longnose dace (Rhinichthys cataractae) and interspecific amplification in five other Leuciscinae species

The longnose dace (Rhinichthys cataractae) appears as a relevant model to address environmental and ecological issues in an evolutionary perspective. Eleven microsatellite markers were characterized for this species. Eight of these loci were highly polymorphic for populations of this species. Between four to 10 loci were also successfully amplified in five closely related species. These markers are believed to be valuable tools for genetic analysis of populations of longnose dace and other Leuciscinae species.     

Characterization of microsatellite loci in Humboldt penguin (Spheniscus humboldti) and cross‐amplification in other penguin species

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.     

Characterization of microsatellite loci in silver carp (Hypophthalmichthys molitrix), and cross‐amplification in other cyprinid species

Captive populations of silver carp (Hypophthalmichthys molitrix), a major aquaculture species in Asia, would undoubtedly benefit from genetic monitoring and improvement programs. We report the isolation and preliminary characterization of 16 microsatellite loci derived from both conventional and microsatellite‐enriched libraries. Inheritance studies confirmed the allelic nature of observed polymorphisms at all loci, while identifying null alleles at two loci. These loci, having varying degrees of polymorphism, should provide useful markers for applied genetic studies. A high degree of cross‐amplification among 10 other cyprinid species suggests that these loci may have more widespread utility.     

Characterization of microsatellite loci in the Jamaican fruit‐eating bat Artibeus jamaicensis and cross‐species amplification

Artibeus jamaicensis is one of the most common bat species in the neotropics, with a well‐defined polygynous social structure in caves. In order to study behaviour and to examine patterns of paternity and relatedness between different harem groups, we developed 14 microsatellite loci from two different enriched genomic libraries. We screened 125 individuals from two different bat colonies and found that polymorphism ranged from five to 13 alleles. Heterozygosity ranged from 63 to 95%. The primers amplified across 14 bat species, indicating their potential utility for population‐level studies in several closely related bat species.     

New microsatellite loci for Carcharhinid sharks (Carcharhinus tilstoni and C. sorrah) and their cross‐amplification in other shark species

Twelve microsatellite DNA markers were isolated in the spot‐tail shark (Carcharhinus sorrah) and nine were isolated in Australian black‐tip shark (Carcharhinus tilstoni). These loci plus 18 others developed for sharks from the genera Negaprion, Ginglymostoma, Carcharodon and Isurus were tested for amplification success on four species of Carcharhinus (including C. sorrah and C. tilstoni) and four other species representing three diverse families. Cross‐amplification was most common within families. Five loci were subsequently tested for polymorphism on 50 C. sorrah and 60 C. tilstoni. The number of alleles per locus was two to 24 and the average heterozygosity was 0.54 (range 0.16–0.87) for C. sorrah and 0.64 (range 0.44–0.78) for C. tilstoni. These loci may be useful tools for genetic analyses of the Carcharhinidae.     

Isolation and characterization of polymorphic microsatellite loci from an EST library of turbot (Scophthalmus maximus) and cross‐species amplification

In the present study, we report 12 polymorphic microsatellite loci developed from a cDNA library from the turbot, Scophthalmus maximus. Observed and expected heterozygosities varied from 0.20 to 1.00 and from 0.18 to 0.78, respectively. No significant linkage disequilibrium between pairs of loci was found, but two loci significantly deviated from Hardy–Weinberg equilibrium after Bonferroni correction. Cross‐species amplifications of these microsatellites in five additional fish species revealed between five and 11 positive amplifications and between zero and four polymorphic loci per species.     

Characterization and cross‐species amplification of microsatellite loci in a Cyprinodon species flock

In this study, two new microsatellite loci from a library of Cyprinodon beltrani from Laguna Chichancanab, Mexico, were characterized. Additionally, cross‐species amplification with primer pairs developed for other Cyprinodon species was performed. The 11 markers show moderate to high levels of polymorphism (two to 33 alleles) in six species of the Cyprinodon flock from Laguna Chichancanab and in their sister species Cyprinodon artifrons. These loci were characterized for population genetic study to detect gene flow between the different endemic pupfish species.     

Isolation and characterization of polymorphic microsatellite loci from an EST‐library of red sea bream (Chrysophrys major) and cross‐species amplification

Microsatellite markers have been developed from a complementary DNA (cDNA) library of red sea bream, Chrysophrys major. Twenty‐eight microsatellites were selected for designing microsatellite primers, of which 11 gave working primer pairs. Observed and expected heterozygosities varied from 0.33 to 1.00 and from 0.38 to 0.83, respectively. Five additional fish species assessed for cross‐species amplification revealed between one and six positive amplifications and between 0 and 6 polymorphic loci per species.     

Ten novel dinucleotide microsatellite loci cloned from the Galápagos sea lion (Zalophus californianus wollebaeki) are polymorphic in other pinniped species

We isolated and characterized 10 novel dinucleotide microsatellite loci from the Galápagos sea lion (Zalophus californianus wollebaeki) and tested their amplification utility in four further otariid species (Zalophus californianus californianus, Arctocephalus gazella, Arctocephalus australis and Eumetopias jubatus) and three phocid species (Hydrurga leptonyx, Halichoerus grypus and Phoca vitulina). All of the loci amplified polymorphic polymerase chain reaction (PCR) products in at least three species other than the Galápagos sea lion. These markers will be useful for studies of pinniped mating systems, genetic structure and genetic diversity.     

Isolation of polymorphic microsatellite loci from Eurasian woodcock (Scolopax rusticola) and their cross‐utility in related species

We isolated one trinucleotide and seven tetranucleotide microsatellite loci for the Eurasian woodcock (Scolopax rusticola). We describe polymerase chain reaction conditions and primers for the successful amplification of these loci and report the results obtained from their use in 42 specimens from two populations in Europe. The number of alleles per locus ranged from three to 15, observed heterozygosity was comprised between 0.11 and 1.00 and expected heterozygosity ranged between 0.10 and 0.91. Cross‐specific amplification experiments highlighted the potential usefulness of these molecular markers for the study of three related scolopacid waders.     

Identification of 15 polymorphic microsatellite loci in the Príncipe seedeater (Serinus rufobrunneus) and assessment of their utility in nine other Serinus species (Fringillidae,Aves)

We tested 74 passerine microsatellite loci for cross‐amplification in the Príncipe seedeater (Serinus rufobrunneus), and identified 15 loci that were both polymorphic and easy to score. In a sample of 113 individuals, the number of alleles ranged between three and 71. Three loci deviated from Hardy–Weinberg equilibrium after correcting for multiple tests, and one locus had high estimated null allele frequency. These 15 loci were highly successful in amplifying polymorphic products also in nine other Serinus species.

Five polymorphic microsatellite loci have been isolated and characterized from random amplified polymorphic DNA product in turbot, Scophthalmus maximus. Twelve microsatellites were selected for designing microsatellite primers, of which five gave working primer pairs. They had between four and nine alleles. Observed and expected heterozygosities varied from 0.76 to 0.90 and from 0.63 to 0.83, respectively. Five additional fish species assessed for cross‐species amplification revealed between one and three positive amplifications and between zero and two polymorphic loci per species.     

Characterization of microsatellite loci isolated in Mountain Plover (Charadrius montanus)

Primers for 15 microsatellite loci were developed for Mountain Plover, a species whose distribution and abundance have been reduced drastically in the past 30 years. In a screen of 126 individuals collected from four breeding locales across the species’ range, levels of polymorphism ranged from two to 13 alleles per locus. No two loci were found to be linked, although one locus revealed significant departures from Hardy–Weinberg equilibrium. These microsatellite loci can be used in population genetic studies, ultimately aiding in management efforts for Mountain Plover. Additionally, these markers can potentially be used in studies investigating the mating system of Mountain Plover.     

Isolation and characterization of microsatellite markers in the gecko Gekko swinhonis and cross‐species amplification in other gekkonid species

Gekko swinhonis is a gekkonid lizard endemic to China, inhabiting Loess Plateau, Huabei Plain, Huanghuai Plain and areas north of the Yangtze River. We characterized 21 dinucleotide microsatellite loci from an AC/AG‐enriched genomic library of G. swinhonis. The number of alleles per locus ranged from eight to 24 and the observed and expected heterozygosities ranged from 0.160 to 0.834 and from 0.584 to 0.917, respectively. We also tested the utility of these loci in other Gekko and Hemidactylus species; many of these loci can be cross‐amplified.     

Isolation and characterization of microsatellite loci in wheat stem sawfly Cephus cinctus and cross‐species amplification in related species

The wheat stem sawfly is an important insect pest of wheat that can cause significant damage to yield and grain quality. Five microsatellite loci were isolated and characterized in wheat stem sawfly, Cephus cinctus, to facilitate future population genetic studies and help delineate their geographical origin. These loci were found to be polymorphic with an expected heterozygosity ranging from 0.304 to 0.937 and an observed heterozygosity ranging from 0.05 to 0.65. Successful cross‐species amplification demonstrates the potential for these markers to provide a valuable tool for future population studies among related Cephus species.     

Isolation and identification of 21 microsatellite loci in the Copper redhorse (Moxostoma hubbsi; Catostomidae) and their variability in other catostomids

Catostomidae represent an important family of freshwater fishes mainly distributed in North America, but also found in Eurasia. This paper describes the development of microsatellite DNA markers for a highly threatened member of this family, the Copper redhorse (Moxostoma hubbsi), as well as cross‐catostomids amplifications. 168 tetra‐nucleotide loci were screened to develop 21 polymorphic markers, with an average number of 8.5 alleles per locus and observed heterozygosity ranging between 0.52 and 1.00. Successful amplification was obtained for 12 other members of the family at between seven to 19 loci, with between two to 18 loci being polymorphic per species.     

Eighteen microsatellite loci in Salix arbutifolia (Salicaceae) and cross-species amplification in Salix and Populus species

Salix arbutifolia is a riparian dioecious tree species that is of conservation concern in Japan because of its highly restricted distribution. Eighteen polymorphic loci of dinucleotide microsatellites were isolated and characterized. Among these, estimates of the expected heterozygosity ranged from 0.350 to 0.879. Cross-species amplification was successful at 9-13 loci among six Salix species and at three loci in one Populus species.     

Isolation and characterization of microsatellite loci from yellowtail Seriola quinqueradiata and cross‐species amplification within the genus Seriola

We developed five microsatellite primer pairs for the yellowtail Seriola quinqueradiata. The loci were highly polymorphic, with eight to 14 alleles per locus, and can be used to study kinship and/or population structure. Many of these primer pairs amplified polymorphic loci in cross‐species amplification tests for two other Seriola species (S. lalandi and S. dumerili).
