Isolation and characterization of microsatellite markers for Passiflora contracta.

ABSTRACT: Passiflora contracta Vitta (Passifloraceae) is an endemic species of the Atlantic Rainforest, one of the most species-rich ecoregions in the world, although extremely endangered. We have developed an enriched microsatellite library in order to fine-scale studies of the genetic structure of P. contracta. Twelve pairs of microsatellite primers were designed, and seven loci were successfully amplified and characterized by genotyping two wild populations of P. contracta. All seven loci were polymorphic, with an average number of alleles found being 4.8 and 5 per population. The cross-species transferability was tested using sister species Passiflora ovalis Vell. Ex Roemer. The development of these markers will contribute to the studies of population genetics in P. contracta as well as future studies concerning diversity patterns in the Atlantic Rainforest, and may also help to establish strategies for the conservation of this species.

Isolation and characterization of microsatellite markers in Beilschmiedia roxburghiana (Lauraceae).

Project description:Although there are as many as 250 species in the genus Beilschmiedia, their genetic diversity has been poorly investigated. Our objective was to develop microsatellite markers for B. roxburghiana to study its genetic diversity for the sustainable management of this species. • Using the microsatellite-enriched library and PCR-based screening method, 22 microsatellite markers were developed and 10 showed high polymorphism in a population. The number of alleles per locus for these 10 microsatellites ranged from five to 19. The observed and expected heterozygosities ranged from 0.298 to 1.000 and from 0.314 to 0.878, respectively. • Our results from the 10 highly polymorphic microsatellites indicate that the principal reproductive mode of B. roxburghiana is clonal in the studied population. These microsatellites will facilitate further studies on genetic diversity and structure in B. roxburghiana.

Isolation and characterization of microsatellite markers for Shorea platyclados (Dipterocarpaceae).

Project description:Microsatellite markers were isolated and characterized in Shorea platyclados (Dipterocarpaceae) for DNA profiling and genetic diversity assessment of this tropical timber species. • Fifteen polymorphic microsatellite loci were developed and characterized in S. platyclados using a genomic library enriched for dinucleotide (CT) repeats. The primers amplified dinucleotide repeats with 3-14 alleles per locus across four natural populations. The observed and expected heterozygosities ranged from 0.292 to 1.000 and from 0.301 to 0.894, respectively. No significant deviation from Hardy-Weinberg equilibrium was detected in the 15 loci. Four loci pairs displayed linkage disequilibrium. • These highly polymorphic markers are adequate for DNA profiling and studies of population genetics in S. platyclados.

Isolation and Characterization of Microsatellite Markers for Soybean Looper (Lepidoptera: Noctuidae).

Project description:We constructed 13 microsatellite markers for Chrysodeixis includens (Walker), a serious crop pest in the Americas. All SSR (Simple Sequence Repeat) markers were polymorphic, with no evidence of linkage disequilibrium between any loci in any population. The total number of alleles per locus ranged from 5 for L3, L9, and L11 to 26 for L6; the mean number of alleles per locus in three populations of C. includens ranged from 2.33 for L3 to 14.67 for L6. Hardy-Weinberg equilibrium (HWE) deviation was not observed in four loci for at least one population (L3, L5, L9, L10). Markers L6, L7, L8, L10, L11, L12, and L13 showed a frequency of null alleles > 0.2 for at least one population. STRUCTURE and F-statistics revealed low population structure among the populations (FST = 0.013) and a high degree of inbreeding (FIS = 0.658). The SSR markers developed here will be useful in future studies on the ecology, demography, host dynamics, and gene flow of C. includens. This information is essential to understand the recent status of C. includens as a key pest in South America.

Isolation and characterization of novel microsatellite markers for yellow perch (Perca flavescens).

Project description:To perform whole genome scanning for complex trait analysis, we isolated and characterized a total of 21 novel genomic-SSRs and EST-SSRs for yellow perch (Perca flavescens), using the methods of construction of SSR-enrichment libraries and EST database mining of a related species P. fluviatilis. Of 16 genomic-SSR primer pairs examined, eight successfully amplified scorable products. The number of alleles at these informative loci varied from 3 - 14 with an average of 8.5 alleles per locus. When tested on wild perch from a population in Pennsylvania, observed and expected heterozygosities ranged from 0.07 - 0.81 and from 0.37 - 0.95, respectively. Of 2,226 EST sequences examined, only 110 (4.93%) contained microsatellites and for those, 13 markers were tested, 12 of which exhibited polymorphism. Compared with genomic-SSRs, EST-SSRs exhibited a lower level of genetic variability with the number of alleles of averaging only 2.6 alleles per locus. Cross-species utility indicated that three of the genomic-SSRs and eight of the EST-SSRs successfully cross-amplified in a related species, the walleye (Sander vitreus).

Isolation and characterization of novel microsatellite markers in pomegranate (Punica granatum L.).

Project description:Pomegranate (Punica granatum L.) has been cultivated from ancient times for its economic, ornamental and medicinal properties globally. Here, we report the isolation and characterization of 12 polymorphic microsatellite markers from a repeat-enriched genomic library of Punica granatum L. The genetic diversity of these loci was assessed in 60 genotypes of Punica granatum L. All loci were variable: the number of polymorphic alleles per locus ranged from two to five (average 2.9). The observed and expected heterozygosities ranged from 0.15 to 0.87 and 0.29 to 0.65, respectively. The polymorphic information content ranged from 0.26 to 0.61 (average: 0.43). To the best of our knowledge, this is the first time that polymorphic microsatellite markers have been reported for P. granatum L. These new markers should allow studies of the population structure and genetic diversity of pomegranate to be performed in the future.

Isolation and characterization of microsatellite markers in the Lepisorus clathratus complex (Polypodiaceae).

Project description:Microsatellites were designed and characterized in the Sino-Himalayan fern Lepisorus clathratus complex (Polypodiaceae) to further study the phylogeography and reproductive ecology of this species. From a genomic library obtained by next-generation sequencing, 10 polymorphic and six monomorphic microsatellite loci were developed. In one population of L. clathratus from Taibaishan in central China, the number of alleles observed for these microsatellites ranged from seven to 29, and observed and expected heterozygosity ranged from 0.463 to 0.919 and from 0.797 to 0.947, respectively. Cross-amplification in other taxa within this complex was successful, but cross-amplification was poor for other congeneric species. This set of newly developed microsatellite markers will be useful for assessing genetic diversity, population structure, and mating system, and to infer polyploid origin in the L. clathratus complex.

Sinanodonta woodiana (Mollusca: Bivalvia: Unionidae): isolation and characterization of the first microsatellite markers.

Project description:Sinanodonta woodiana (Lea, 1834) is a large Unionid species with a real invasion success. It colonized Europe, Central America, the Indonesian Islands and recently North America. The species life cycle involves a larval parasitic stage on freshwater fish species which contributes to the spread of the mussel. In this paper we describe, for the first time, eight polymorphic microsatellite loci for the species Sinanodonta woodiana. The genetic screening of individuals confirmed that all loci were highly polymorphic. The number of alleles per locus ranged from 7 to 14 and the observed heterozygosity ranged from 0.650 to 0.950. These loci should prove useful to study the species population genetics which could help to infer important aspects of the invasion process.
