The highly polymorphic microsatellite markers for the greater long‐tailed hamster (Tscherskia triton)

We isolated 25 dinucleotide microsatellite loci from the greater long‐tailed hamster (Tscherskia triton) populations in North China. We developed the amplification conditions of polymerase chain reaction for producing high‐resolution genetic markers for each locus. We found 10 microsatellite loci were highly polymorphic in 90 individual hamsters from three areas of North China, and the number of alleles in each locus varied from three to 11. These markers are potential tools for studying the genetic variation of the natural populations of this species.     

Development and characterization of novel tetra‐ and dinucleotide microsatellite markers for the French Polynesia black‐lipped pearl oyster,Pinctada margaritifera

Ten microsatellite loci were developed for the black‐lipped pearl oyster Pinctada margaritifera with a magnetic bead enrichment protocol. These tetra‐ and dinucleotide markers were polymorphic, with 10 to 43 alleles observed in 97 individuals from two Tuamotu atoll populations. Most loci revealed significant genic differentiation between the two populations and also exhibited some degree of heterozygote deficiencies, probably due to the presence of null alleles. These loci should be very useful to describe genetic structure, genetic variability and reproductive success in the various aquaculture and wild populations of pearl oyster in French Polynesia.     

Characterization of highly polymorphic nuclear microsatellite loci from the ascidian Ciona intestinalis

Eight nuclear polymorphic microsatellite markers were characterized from the ascidian Ciona intestinalis whole genome sequence. The behaviour of these loci was investigated against two geographically distinct populations: one from Plymouth, UK the other from the Fusaro Lagoon, Italy, both belonging to the type A Ciona cryptic species. The markers exhibited six to 29 alleles and average observed heterozygosity ranging from 0.06 to 0.73. These new microsatellite loci demonstrated to be valuable tools for both population genetic analysis at different scales and genetic identification of mutant phenotypes frequently encountered in Mediterranean populations of C. intestinalis.     

Development of compound microsatellite markers in the marine phytoplankton Alexandrium tamiyavanichii (Dinophyceae)

We isolated 24 polymorphic microsatellite markers from the toxic dinoflagellate A. tamiyavanichii. These loci provide a class of highly variable genetic markers, as the number of alleles ranged from 2 to 6, and the estimate of gene diversity was from 0.269 to 0.739 across the 24 microsatellites. We consider that these loci have a potentially to reveal the genetic structure and gene flow among A. tamiyavanichii populations.     

Isolation and characterization of eleven microsatellite loci in small abalone, Haliotis diversicolor Reeve

Eleven novel microsatellite markers were isolated from small abalone, Haliotis diversicolor Reeve. These loci were tested on 22 individuals from two different geographic populations. We identified a total of 162 alleles from the 11 microsatellite loci. All of the loci were highly polymorphic. Polymorphism information content (PIC) is ranging from 0.7276 to 0.9163. Observed and expected heterozygosities ranged from 0.2727 to 1.0000 and from 0.7738 to 0.9429, respectively. Three loci deviated significantly from Hardy–Weinberg equilibrium. No pairs of loci displayed linkage disequilibrium. These polymorphic markers will be used to analyze population structure, genetic diversity and construct a genetic linkage map. Xin Zhan and Hai-Yan Hu contribute equally to this study.     

Development of microsatellite markers for the tropical moss,Acanthorrhynchium papillatum

We isolated and characterized microsatellite loci for the palaeotropic moss, Acanthorrhynchium papillatum. Eight loci tested on 98 gametophytic samples generated four to 26 alleles per locus with genetic diversities ranging from 0.578 to 0.936. These microsatellite loci are now being used as genetic markers for studies on the effects of deforestation on moss populations in South‐East Asia.     

Development of microsatellite markers in the toxic dinoflagellate Alexandrium tamarense (Dinophyceae)

Outbreaks of paralytic shellfish poisoning caused by the toxic dinoflagellate Alexandrium tamarense (Dinophyceae) are currently a serious problem from an economic and food hygiene point of view throughout the world. We isolated 13 polymorphic microsatellite loci from this species. These loci provided microsatellite markers with high polymorphism ranging from four to 15 alleles per locus and gene diversity between 0.632 and 0.974. The markers are available for more detailed investigations of genetic structure and gene flow of A. tamarense populations.     

Isolation and characterization of 12 microsatellite loci for cross-species amplification in the cyprinid gudgeons Squalidus chankaensis and S. japonicus

Twelve dinucleotide markers were successfully isolated and characterized from a microsatellite‐enriched genomic library obtained for the gudgeon Squalidus chankaensis biwae. These markers were also available for the congeners S. c. tsuchigae and S. japonicus from Japan, which had five to 46 alleles and an expected heterozygosity ranging from zero to 0.946. Linkage equilibrium was observed at all loci, and most loci did not show significant deviation from Hardy–Weinberg equilibrium. The isolated microsatellite markers will be useful for genetic diversity studies of Squalidus populations.     

Polymorphic microsatellite loci in the sponge Crambe crambe (Porifera: Poecilosclerida) and their variation in two distant populations

Seven polymorphic microsatellite loci were characterized in the marine encrusting sponge Crambe crambe from a partial genomic DNA‐enriched library. Preliminary data on allelic variation of these loci in two distant populations of C. crambe are presented to assess their potential utility as high‐resolution genetic markers for this species. The number of alleles per locus ranged between three and 16 and the distributions of allele frequencies differed considerably between the two populations, indicating a marked genetic differentiation between them. These are the first microsatellite loci reported from any species in the phylum.

We isolated 15 polymorphic microsatellites from one of the most noxious red tide‐causing dinoflagellate species, Heterocapsa circularisquama. These loci provide one class of highly variable genetic markers, as the number of alleles ranged from two to six, and the estimate of gene diversity was from 0.205 to 0.684 across the 15 microsatellites. These loci have the potential to reveal genetic structure and gene flow among H. circularisquama populations.

Isolation and characterization of microsatellite loci in the endangered perennial Eleocharis parvula (Cyperaceae), emerging in the 2011 tsunami inundation areas

Using 454 pyrosequencing, we designed primers for 12 microsatellite loci in the endangered perennial herb Eleocharis parvula, which has established many new populations in areas disturbed by the huge tsunami following the Great East Japan Earthquake in 2011. Polymorphism of these 12 loci was assessed in 25 individuals from two newly established populations in the tsunami disaster area. The number of alleles ranged from two to five, and the ranges of observed and expected heterozygosity were 0.167–0.833 and 0.219–0.727, respectively. These loci were not linked to each other and had no null alleles. These markers will be useful in studies of the genetic diversity, population dynamics and conservation of E. parvula.     

Isolation and characterization of microsatellite loci of Lycopodium fordii Bak. (Lycopodiaceae, Pteridophyta)

Lycopodium fordii Bak. (Lycopodiaceae, Pteridophyta) is a gardening plant with a native, fragmentary distribution in Taiwan. In this study, we described the development of eleven microsatellite loci in L. fordii for genetic studies. These new markers were tested in 16 individuals of three populations. The number of alleles ranged from 1 to 5 and the expected heterozygosity from 0.41746 to 0.72222. Four of the nine polymorphic loci were significantly deviated from Hardy-Weinberg expectations due to the heterozygote deficiency. The microsatellite markers have also been proved as informative genetic markers for other 15 Lycopodium species.     

Isolation and characterization of microsatellite markers for Pinellia ternata and cross-species amplification

In this study, we isolated and characterized 12 microsatellite loci for Pinellia ternata. Polymorphism of these 12 loci was assessed in 46 individuals collected from two wild populations. All the loci were polymorphic with four to 13 alleles per locus and the observed and expected heterozygosities ranged from 0.312 to 0.680 and from 0.506 to 0.734, respectively. None of the loci showed significant deviation from Hardy–Weinberg equilibrium (P < 0.05). No significant linkage disequilibrium was observed between pairs of studied loci. In addition, most markers amplified successfully in three closely related taxa that are Pinellia cordata, P. peltata and P. pedatisecta. These microsatellite markers could provide a useful tool for genetic structure studies of the Pinellia species.     

Ten new microsatellite loci for analysis of genetic diversity in isolated populations of the Alpine land snail <Emphasis Type="Italic">Cylindrus obtusus</Emphasis>

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.     

Characterization of microsatellite loci in Brachyderes rugatus,the Canary Islands pine weevil (Coleoptera: Curculionidae)

The Canary Island pine weevil Brachyderes rugatus (Wollaston) consists of four allopatric subspecies that are thought to have arisen from several historic colonization events within the archipelago. We have isolated and optimized seven microsatellite loci from Brachyderes rugatus calvus from Gran Canaria. Six of these loci are polymorphic within B. rugatus (11–22 alleles per locus; heterozygosity between 0.43 and 0.84). There is no evidence for heterozygote deficit within populations or for linkage disequilibrium between pairs of loci. These molecular markers are likely to prove useful tools for quantifying the genetic variability of bottlenecked island populations.     

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.     

Development of compound microsatellite markers in the harmful dinoflagellate Cochlodinium polykrikoides (Dinophyceae)

We isolated 15 polymorphic microsatellites from Cochlodinium polykrikoides. These loci provide a class of highly variable genetic markers, as the number of alleles ranged from two to 15, and the estimate of gene diversity was from 0.083 to 0.880 across the 15 microsatellites. We consider that these loci have a potential to reveal the genetic structure and gene flow among C. polykrikoides populations.     

Microsatellite markers developed for a Swedish population of sand lizard (<Emphasis Type="Italic">Lacerta agilis</Emphasis>)

Populations of sand lizards (Lacerta agilis) are declining throughout its north-western range. Here we characterize fifteen new microsatellite markers developed specifically for parentage analysis in a small Swedish population of sand lizards. These loci were screened in the Asketunnan population and a much larger and genetically diverse Hungarian population, with heterozygosities ranging from (0.217–0.875) and (0.400–0.974), respectively. All loci were in Hardy-Weinberg Equilibrium in the Swedish population but eight loci had significant heterozygote deficiencies in the Hungarian population. Two loci were significantly linked in both populations. These microsatellite loci are likely to be applicable in research on other sand lizard populations throughout Europe.
