Polymorphic microsatellite loci in the European subterranean termite,Reticulitermes santonensis Feytaud

We report on the identification and characterization of two dinucleotide, two trinucleotide and eight tetranucleotide microsatellite DNA loci isolated from the European subterranean termite Reticulitermes santonensis. We tested the loci on 51–92 individuals from 46 colonies from different regions of France. Eleven loci were polymorphic with 2–8 alleles per locus and low observed heterozygosities (0.10–0.48). We also tested the loci on 17–20 individuals from 10 colonies in the closely related North American species R. flavipes and found significantly more alleles (2–9 alleles per locus) and higher observed heterozygosities (0.15–0.80) than in R. santonensis. The lower observed heterozygosities in R. santonensis are consistent with higher levels of inbreeding in these colonies due to the presence of numerous inbred replacement reproductives.     

Isolation and characterization of the first microsatellite loci from the order Psocoptera in the economically important pest insect Liposcelis decolor (Pearman) and cross‐species amplification

A total of 11 microsatellite loci from the invasive insect pest Liposcelis decolor were isolated and characterized of which six loci were polymorphic. A population survey involving a total of 30–192 individuals per locus from five populations revealed a range of four to seven alleles per locus and moderate observed heterozygosities (0.183–0.565), highlighting the utility of these loci in further population genetic studies. Cross‐species amplifications were successful for two to 11 loci in five other Liposcelis species also of international economic importance.     

Isolation of microsatellite loci from the endangered plant Galium catalinense subspecies acrispum (Rubiaceae)

Galium catalinense subspecies acrispum (Rubiaceae) is a state‐endangered perennial shrub endemic to San Clemente Island. Eight polymorphic microsatellite loci were isolated from G. catalinense ssp. acrispum. These loci show high levels of variability, averaging 6.5 alleles per locus and an expected heterozygosity of 0.550. One locus exhibited significant deviations from Hardy–Weinberg equilibrium (P < 0.01) and one pair of loci exhibited significant linkage disequilibrium.     

Isolation of microsatellites from two species of scleractinian coral

Microsatellites were isolated from two broadcast‐spawning species of scleractinian coral (Platygyra daedalea and Goniastrea favulus) from Australia's Great Barrier Reef. We found 27 microsatellites across both species, although only five loci were polymorphic in each species. Microsatellite loci displayed a wide range of diversity levels with four to 11 alleles per locus (H_O = 0.26–0.91) in P. daedalea and two to seven alleles per locus (H_O = 0.16–0.96) in G. favulus. Most loci showed departures from Hardy–Weinberg equilibrium which may reflect nonrandom mating but may also be related to difficulties associated with coral DNA.     

New microsatellite markers for the snow crab Chionoecetes opilio (Brachyura: Majidae)

Nine novel microsatellite loci were isolated from Chionoecetes opilio by screening an enriched genomic library using nonradioactive polymerase chain reaction techniques, and the polymorphisms were examined to estimate genetic variability. The genetic variabilities varied depending on the locus. All loci were found to be polymorphic with an average of 9.7 alleles per locus (range 3–25). The observed and expected heterozygosities ranged from 0.80 to 0.98 and from 0.56 to 0.95, respectively. Five loci showed significant Hardy–Weinberg disequilibrium at the P < 0.05 level. The high variabilities revealed in this study suggest that these microsatellite loci should provide useful markers for genetic variation monitoring of C. opilio.     

Isolation and characterization of microsatellite markers for Viola mirabilis (Violaceae) using a next‐generation sequencing platform

We isolated and characterized microsatellite loci in Viola mirabilis (Violaceae), an endangered species from South Korea. Twenty‐three polymorphic microsatellite loci were developed and tested in Korean, Chinese and Japanese populations. The number of alleles per locus varied from two to eight. The observed and expected heterozygosities within the three populations were 0.000–0.625 and 0.469–0.695, respectively. A total of six loci in the Korean population, one locus in the Chinese population and seven loci in the Japanese population deviated from Hardy–Weinberg equilibrium. We expect that these newly developed microsatellite markers will contribute to understanding the phylogeography and population genetics of V. mirabilis, which will aid in developing conservation strategies for this species.     

Microsatellite loci in the Japanese subterranean termite,Reticulitermes speratus

Reticulitermes termites have such a cryptic life style and complex colony structure that polymorphic microsatellite markers are desired to investigate their population and colony structures. We successfully isolated seven microsatellite loci in R. speratus , the Japanese subterranean termite, five of which were polymorphic. These polymorphic loci had 2–8 alleles per locus and their observed heterozygosities ranged from 0.059 to 0.438. These five loci were also polymorphic in R . kanmonensis , distributed sympatrically with R. speratus in the Kanmon Region, western Japan; the number of alleles per locus was 2–5, and observed heterozygosity was 0.176–0.625.     

Microsatellite DNA loci in the rock bream Oplegnathus fasciatus

Nine novel microsatellite loci were isolated from Oplegnathus fasciatus by screening an enriched genomic library using nonradioactive PCR (polymerase chain reaction) techniques. All loci were found to be polymorphic with an average of 8.1 alleles per locus (range 3–15). The mean observed and expected heterozygosities were 0.71 (range 0.40–1.00) and 0.74 (range 0.50–0.90), respectively. Two loci showed significant Hardy–Weinberg disequilibrium at the P < 0.05 level. The high variabilities revealed in this study suggest that these microsatellite loci should provide useful markers for genetic variation monitoring of O. fasciatus.     

Microsatellite loci for behavioural studies of Eclectus parrot (Eclectus roratus: Aves)

Ten polymorphic microsatellite loci were isolated from the cooperatively breeding and sexually dichromatic Eclectus parrot (Eclectus roratus). Nine loci were in Hardy–Weinberg equilibrium and unlinked. One locus, Ero1, was presumed to be sex‐linked since females, the heterogametic sex, were all homozygous, whereas 72% of males were heterozygous. A DNA database search revealed that Ero8 is probably an independent isolation of the microsatellite locus AgGT83 of the parrot Amozona guildingii. With high heterozygosity (0.41–0.89) and number of alleles (two to 13), these loci should prove useful for investigating the mating system of these unusual Australasian parrots.     

PERMANENT GENETIC RESOURCES: Identification and characterization of 14 polymorphic microsatellite loci in the argasid tick Ornithodoros coriaceus

Fourteen polymorphic microsatellite loci (di, tetra and di‐tetra complexes) were developed for the argasid tick Ornithodoros coriaceus. Polymorphism was assessed for 56 individuals from two populations separated by ~95 km. All loci were polymorphic (X = 7, range 3–17 alleles). All loci were in Hardy–Weinberg equilibrium except for one locus (OrC 8) in a single population (P < 0.00119, after Bonferroni correction for multiple tests).     

Polymorphic tetranucleotide microsatellite markers in the Caribbean spiny lobster,Panulirus argus

Ten tetranucleotide microsatellite loci are described for the Caribbean spiny lobster Panulirus argus. Loci were polymorphic (4–15 alleles per locus) and exhibited high levels of expected (0.553–0.921) and observed heterozygosity (0.469–0.906) from samples caught off Belize and Puerto Rico coasts. No significant departure from Hardy–Weinberg equilibrium conditions were observed for any locus. All microsatellite loci should be useful for assessing population discrimination for this valuable marine animal currently subjected to excessive fishing efforts.     

Characterization of 24 microsatellite loci in delta smelt, Hypomesus transpacificus, and their cross-species amplification in two other smelt species of the Osmeridae family

We characterized 24 polymorphic tetranucleotide microsatellite loci for delta smelt (Hypomesus transpacificus) endemic to the San Francisco Bay Estuary, CA, USA. Screening of samples (n = 30) yielded two to 26 alleles per locus with observed levels of heterozygosity ranging from 0.17 to 1.0. Only one locus deviated from Hardy–Weinberg equilibrium, suggesting these individuals originate from a single panmictic population. Linkage disequilibrium was found in two pairs of loci after excluding the locus out of Hardy–Weinberg equilibrium. Twenty‐two primer pairs cross‐amplified in wakasagi smelt (Hypomesus nipponensis), and 15 primer pairs cross‐amplified in longfin smelt (Spirinchus thaleichthys).     

Polymorphic tetranucleotide microsatellite loci in the Hwamei (Garrulax canorus canorus) (Timaliidae)

Eight polymorphic tetrarepeat (GATA)_n, microsatellite loci were isolated from a babbler, Hwamei (Garrulax canorus canorus). We evaluated the polymorphism of these microsatellite loci by genotyping 36–48 individuals from the Asian mainland. The number of alleles for each locus ranged from eight to 29. The heterozygosity was between 0.587 and 0.978. Except for one locus, genotype frequencies of these microsatellites did not significantly deviate from the Hardy–Weinberg expectation. These markers should be useful for monitoring potential hybridization between different Hwamei subspecies and provide new insights into the mating system and geographical differentiation of these birds.     

Cross‐species amplification among peromyscines of new microsatellite DNA loci from the oldfield mouse (Peromyscus polionotus subgriseus)

We describe polymerase chain reaction (PCR) primers and conditions to amplify 11 microsatellite DNA loci isolated from the oldfield mouse (Peromyscus polionotus subgriseus). These were tested for amplification using nine species and subspecies maintained at the Peromyscus Genetic Stock Center, with an average success rate of 65% and two loci amplifying in all species. Polymorphism was tested within the P. polionotus subgriseus and the recently obtained P. maniculatus sonorensis colonies. P. p. subgriseus had modest numbers of alleles per locus (1–4), whereas P. m. sonorensis had many alleles per locus (5–10) and high expected heterozygosities (0.625–0.878).     

Nine new polymorphic microsatellite loci for the amplification of archived otolith DNA of Atlantic cod,Gadus morhua L.

Nine out of 22 microsatellite primers tested were successfully amplified on three samples of cod Gadus morhua L. (two contemporary and one archived otolith samples). All loci were polymorphic (5–23 alleles/locus). The average observed heterozygosity across loci and samples was 0.625, ranging from 0.294 to 0.895 at each locus. All loci were under Hardy–Weinberg equilibrium, except PGmo56 that showed significant excess of heterozygotes in all studied samples. The isolated loci were suitable for degraded DNA and therefore useful for conducting a long‐term temporal study with DNA obtained from archived otoliths of cod.     

Microsatellite markers in Fijian crested iguanas (Brachylophus vitiensis) also amplify Fijian banded iguanas (B. fasciatus)

Five microsatellite markers were isolated from the Fijian crested iguana (Brachylophus vitiensis) using an enrichment technique. These loci also amplified the Fijian banded iguana (B. fasciatus). All five loci were polymorphic with between 2–7 and 4–7 alleles per locus in B. vitiensis and B. fasciatus, respectively. Heterozygosity (H_O) values ranged from 0.069 to 0.875. These markers were useful in resolving kinship relationships and will aid future endeavours by the captive management program to conserve genetic diversity.     

Development and characterization of polymorphic microsatellite DNA loci for the endangered dusky gopher frog,Rana sevosa,and two closely related species,Rana capito and Rana areolata

A microsatellite library was developed using genomic DNA of the endangered dusky gopher frog, Rana sevosa. Polymerase chain reaction (PCR) primers and conditions are presented for R. sevosa (eight loci) and two sister taxa — other gopher frogs, Rana capito (seven loci) and crawfish frogs, Rana areolata (three loci). Polymorphism of each microsatellite locus was evaluated for each species. All loci have moderate to high genetic variation in terms of allelic richness (four to 10 alleles per locus), observed heterozygosity (0.595–0.946), and expected heterozygosity (0.531–0.856).     

Development and cross-species testing of western bluebird (Sialia mexicana) microsatellite primers

Western and eastern bluebirds (Sialia mexicana and S. sialis) are socially monogamous passerines that engage in extra‐pair copulations. We obtained microsatellites from S. mexicana and optimized and characterized 15 microsatellite DNA loci in 60 individuals of this species. Primer pairs yielded an average of 13 alleles per locus in western bluebirds (range 3–35 alleles) with an average observed heterozygosity of 0.68 (range 0.27–0.88). All 15 loci also successfully amplified in S. sialis (n = 24), with an average of 11.5 alleles per locus (range 4–26) and an average observed heterozygosity of 0.59 (range 0.22–0.90).     

Cloning and characterization of novel microsatellite DNA markers for the grass rockfish,Sebastes rastrelliger,and cross‐species amplification in 10 related Sebastes spp

Here we report development and characterization of seven polymorphic loci derived from grass rockfish (Sebastes rastrelliger) genomic DNA phagemid libraries enriched for microsatellite motifs. Within grass rockfish, average allelic diversity was 11.3 alleles per locus and average heterozygosity was 0.73. The seven loci also were surveyed in 10 related species of Sebastes, where allelic diversity ranged from highly polymorphic to monomorphic. Deviations from Hardy–Weinberg were nonsignificant in all but one species/locus combination suggesting low occurrence of null alleles. Significant linkage disequilibrium was detected among three loci, but these events were limited to a single species in each case.     

Isolation and characterization of microsatellite loci in the flat‐headed bat (Tylonycteris pachypus)

Microsatellite loci were developed in the flat‐headed bat (Tylonycteris pachypus) from genomic DNA using an enriched library method. Nine loci were tested on 48 individuals sampled from Guangxi Province, China. The mean number of observed alleles per locus was 6.4 (range 4–12). Observed and expected heterozygosity values ranged from 0.24 to 0.83 and from 0.30 to 0.89, respectively. One locus revealed significant departure from Hardy–Weinberg equilibrium and no significant linkage disequilibrium was detected between loci pairs. These markers will be used to examine genetic structure and parentage analysis in this species.
