The number of alleles varied from three to 22 in a sample of 22 individuals from one population. Expected heterozygosities ranged from 0.354 to 0.979. These microsatellites allow us to investigate reproductive success of individuals, alternative mating strategies as well as population structure and metapopulation dynamics of this species.     

Eight polymorphic microsatellite markers developed in the Chinese scorpion, Mesobuthus martensii (Scorpiones: Buthidae)

Eight polymorphic di- and trinucleotide microsatellite loci were developed in the Chinese scorpion, Mesobuthus martensii. The expected heterozygosity at these loci ranges from 0.019 to 0.860, with the observed allele numbers varying from two to 25. Overall, there were no deviations from Hardy-Weinberg equilibrium and no observed linkage disequilibrium after Bonferroni correction. Cross-species amplification of these loci in Mesobuthus eupeus revealed that five loci can amplify successfully in this species. The polymorphic microsatellite DNA markers reported here should provide helpful means to address questions concerning phylogeographical patterns and evolutionary history of M. martensii and closely related species.     

Isolation and multiplex genotyping of polymorphic microsatellite DNA markers in the snakehead murrel, Channa striata

Seven polymorphic microsatellite loci were isolated and characterized for the snakehead murrel, Channa striata (Channidae), a valuable tropical freshwater fish species. Among 25 specimens collected from Kedah state in Malaysia, the number of alleles per locus ranged from 2 to 7. Observed and expected heterozygosities ranged from 0.120 to 0.880 and 0.117 to 0.698, respectively. A single locus (CS1-C07) was significantly deviated from Hardy-Weinberg equilibrium after Bonferroni correction. These novel markers would be useful for population genetic studies of the C. striata.     

Development and characterization of novel, polymorphic microsatellite markers for oat crown rust, Puccinia coronata

We report the development of 37 novel and polymorphic microsatellite markers for oat crown rust, Puccinia coronata f.sp. avenae. The allelic diversity ranged from two to 16 alleles per locus. Observed heterozygosity ranged from 0.000 to 0.971, and expected heterozygosity from 0.057 to 0.848. Thirteen of the loci were not in Hardy-Weinberg equilibrium, due to either the presence of null alleles, small sample size, or the effects of population subdivision (Wahlund's effect). All 37 primer pairs were tested with P. graminis and P. triticina showing that they are specific to P. coronata.

The observed genotypic frequencies in five loci were significantly deviated from Hardy–Weinberg expectations. The high variability revealed in this study suggested that these microsatellite loci should provide useful markers for population genetics of A. japonicus.     

Isolation and characterization of polymorphic microsatellite markers in Zabrotes subfasciatus Boheman (Coleoptera: Bruchidae)

Bruchid beetles of the genus Zabrotes (Coleoptera: Bruchidae) are important worldwide pests of legume seeds. Samples of Zabrotes subfasciatus and Z. sylvestris were collected from seeds of two Phaseolus species throughout Mexico to assess the role of host plant variation and plant domestication on the evolution of host use in this species. For this purpose six polymorphic microsatellite loci were isolated and characterized for the bruchid Z. subfasciatus. Cross‐species amplification tests were performed on Z. sylvestris and revealed that three loci amplified successfully and were polymorphic in this closely related species.

We characterized 15 polymorphic microsatellite loci for the giant spiny frog, Paa spinosa. These loci were highly polymorphic when screened in 38 individuals from two different populations, with nine to 23 alleles per locus. The range of observed and expected heterozygosities was 0.231-0.916 and 0.296-0.944, respectively. These polymorphic loci will be useful for assessing genetic diversity, population structure, gene flow, population assignment and determining paternity in the giant spiny frog.     

Novel tetranucleotide microsatellite DNA markers for the wood frog,Rana sylvatica

Fifteen tetranucleotide microsatellite loci were identified and characterized for wood frogs (Rana sylvatica) collected from three vernal pools in the southeastern US. These markers revealed a high degree of genetic diversity (nine to 34 alleles per locus), heterozygosity (30.6–92.3%) and allelic heterogeneity (69% of comparisons were statistically significant). Considerable differentiation among populations was observed as genetic distances (chord) ranged between 0.40 and 0.55 and all F_ST values (0.02–0.05) were statistically significant. Genotypic assignment tests correctly classified 103 of 113 individuals to their respective collection. These markers should prove useful for investigating fine‐scale population structure and metapopulation dynamics.

Eight di‐, tri‐ and tetranucleotide microsatellite markers were developed for the haremic sandperch Parapercis cylindrica using a linker‐ligated, magnetic bead enrichment protocol. Screening of at least 17 individuals showed these markers to be polymorphic with observed heterozygosity ranging from 0.381 to 1.000 (mean = 0.742) and the numbers of alleles ranging from three to 18. The average polymorphic information content for these eight loci was 0.723. These markers may be used for parentage studies aimed at exploring the complex mating strategies employed by this haremic coral reef fish and will be valuable for population genetic studies.
