Eleven novel polymorphic microsatellite Loci for oval squid Sepioteuthis lessoniana (Shiro-Ika type).

ABSTRACT: The oval squid Sepioteuthis lessoniana is one of the most economically important squid species in Japan; however, its population structure is poorly understood due to the lack of hypervariable markers. Such information is critical for managing sustainable fisheries, as well as for ensuring the existence of wild S. lessoniana stocks. Eleven candidate microsatellite loci were isolated from a small insert genomic DNA library. Polymorphisms in these 11 loci were screened in 24 wild individuals. The number of alleles per locus was found to range from 5 to 19 alleles, and the observed heterozygosity ranged from 0.292 to 0.958. No evidence for linkage disequilibrium was detected among all the loci. The genotypic proportions conformed to Hardy-Weinberg equilibrium, except at one locus. In conclusion, these polymorphic microsatellite loci may be used to develop a genetic framework to manage S. lessoniana in the future.

Isolation and characterization of eleven polymorphic microsatellite loci for the valuable medicinal plant Dendrobium huoshanense and cross-species amplification.

Project description:Dendrobium huoshanense (Orchidaceae) is a perennial herb and a widely used medicinal plant in Traditional Chinese medicine (TCM) endemic to Huoshan County town in Anhui province in Southeast China. A microsatellite-enriched genomic DNA library of D. huoshanense was developed and screened to identify marker loci. Eleven polymorphic loci were isolated and analyzed by screening 25 individuals collected from a natural population. The number of alleles per locus ranged from 2 to 5. The observed and expected heterozygosities ranged from 0.227 to 0.818 and from 0.317 to 0.757, respectively. Two loci showed significant deviations from Hardy-Weinberg equilibrium and four of the pairwise comparisons of loci revealed linkage disequilibrium (p < 0.05). These microsatellite loci were cross-amplified for five congeneric species and seven loci can be amplified in all species. These simple sequence repeats (SSR) markers are useful in genetic studies of D. huoshanense and other related species and in conservation decision-making.

Eleven microsatellite loci isolated from the banded wren (Thryothorus pleurostictus).

Project description:We describe 11 microsatellite loci isolated from the Banded Wren (Thryothorus pleurostictus), a Neotropical species for which understanding the genetic mating system is important for testing questions about the species' unusual vocal behavior. Screening of these loci revealed extremely low allelic variation in a Costa Rican population. Allelic variation at these and other previously developed loci is substantially higher in two other wren species, the southern house wren (Troglodytes aedon bonariae) and rufous-and-white wren (Thryothorus rufalbus), suggesting that the low allelic diversity in the banded wren results from demographic bottlenecks rather than locus-sampling artifacts.

Development of 14 polymorphic microsatellite loci for Ficus tikoua (Moraceae).

Project description:Polymorphic microsatellite markers were developed to facilitate studies on the fine-scale population genetic structure of Ficus tikoua (Moraceae), a prostrate shrub known to have highly restricted gene flow. Microsatellite primers were developed using the biotin-streptavidin capture method and scanned for polymorphism within 76 individuals sampled from three natural F. tikoua populations. Fourteen loci were shown to be polymorphic, with allele numbers ranging from three to 16. The observed and expected heterozygosity in the three populations ranged from 0 to 1 and from 0 to 0.87, respectively. Substantial divergence was found among the populations at some loci. All loci can be successfully amplified in at least eight other Ficus species, indicating good transferability within the genus. The 14 microsatellite loci will be a helpful tool for assessing the fine-scale genetic structure of F. tikoua.

Characterization of polymorphic microsatellite loci in the Antarctic krill Euphausia superba.

Project description:BACKGROUND: The Antarctic krill, Euphausia superba is a pelagic crustacean, abundant in high-density swarms (10,000 - 30,000 ind/m2) with a circumpolar distribution and a key role in the food web of the Southern Ocean. Only three EST derived microsatellite markers have been used in previous genetic studies, hence we developed additional highly polymorphic microsatellite markers to allow robust studies of the genetic variability and population differentiation within this species. FINDINGS: The microsatellite markers described here were obtained through an enriched genomic library, followed by 454 pyrosequencing. A total of 10 microsatellite markers were tested in 32 individuals from the Antarctic Peninsula. One of the tested loci was fixed for one allele while the other was variable. Of the remaining nine markers, seven showed no departure from Hardy-Weinberg equilibrium. The mean number of alleles was 14.9. CONCLUSIONS: These markers open perspectives for population genetic studies of this species to unravel genetic structure, dispersal and population biology, vital information for future conservation.

Isolation and characterization of polymorphic microsatellite loci in Spondias radlkoferi (Anacardiaceae).

Project description:UNLABELLED: PREMISE OF THE STUDY:Microsatellite markers were developed for Spondias radlkoferi to assess the impact of primate seed dispersal on the genetic diversity and structure of this important tree species of Anacardiaceae. • METHODS AND RESULTS:Fourteen polymorphic loci were isolated from S. radlkoferi through 454 GS-FLX Titanium pyrosequencing of genomic DNA. The number of alleles ranged from three to 12. The observed and expected heterozygosities ranged from 0.382 to 1.00 and from 0.353 to 0.733, respectively. The amplification was also successful in S. mombin and two genera of Anacardiaceae: Rhus aromatica and Toxicodendron radicans. • CONCLUSIONS:These microsatellite loci will be useful to assess the genetic diversity and population structure of S. radlkoferi and related species, and will allow us to investigate the effects of seed dispersal by spider monkeys (Ateles geoffroyi) on the genetic structure and diversity of S. radlkoferi populations in a fragmented rainforest.

Development and characterization of polymorphic microsatellite loci for Saxifraga egregia (Saxifragaceae).

Project description:Saxifraga egregia (Saxifragaceae) is a perennial herb that is endemic to the Qinghai-Tibet Plateau. We developed 12 polymorphic microsatellite loci for S. egregia to investigate its population genetics. Forty-eight pairs of microsatellite primers (including 36 monomorphic loci) were isolated and characterized by magnetic bead enrichment. Twelve of these markers showed polymorphism, and the number of alleles per locus ranged from four to 14 across 50 individuals from three populations of S. egregia. No linkage disequilibrium was detected in any pair of loci. These polymorphic markers are expected to be helpful in further studies on the systematics and phylogeography of S. egregia in the Qinghai-Tibet Plateau.

Isolation and characterization of polymorphic microsatellite loci in Selliera radicans (Goodeniaceae).

Project description:Microsatellite markers were developed for species in the genus Selliera (Goodeniaceae) for future investigations of population genetic structure and interspecific hybridization within the genus. Using 454 pyrosequencing, 15 new markers were developed from microsatellite loci isolated from S. radicans. Primers for the new markers amplify di- and trinucleotide repeat loci from the three Selliera species screened. Ten of the new markers are polymorphic in S. radicans and six of those 10 loci were found to be polymorphic within each congener. For the focal species, S. radicans, the average number of alleles per locus is 3.7 (SE = 0.60) and the average observed and expected heterozygosities are 0.23 (SE = 0.07) and 0.47 (SE = 0.08), respectively. The new markers provide an important resource for future investigations in the genus Selliera for both population genetics and research into hybridization between species.

Polymorphic microsatellite loci isolated from the Squalidus argentatus using PCR-Based Isolation of Microsatellite Arrays (PIMA).

Project description:Squalidus argentatus (Sauvage and Dabry de Thiersant 1874) is a small-sized freshwater fish which is distributed in Mainland China, Hainan Island and Taiwan. The populations of S. argentatus have dropped sharply probably due to overharvesting and water pollution recently. Eleven polymorphic microsatellite markers were developed for the cyprinid fish S. argentatus. These new markers were tested on 43 individuals collected from Yangtze River and Qiantang River. The number of alleles, observed and expected heterozygosity per locus, in two populations ranged from 3 to 14, from 0.333 to 0.954 and from 0.480 to 0.928, respectively. Only two loci are significantly deviated from Hardy-Weinberg expectations due to the heterozygote deficiency. No significant linkage disequilibrium was detected between the pairwise comparisons of these loci. These polymorphic microsatellite loci will enable us to study the genetic variation, population structure, and conservation genetics of this species in the future.

Polymorphic microsatellite loci for Haumania danckelmaniana and transferability to H. liebrechtsiana (Marantaceae).

Project description:PREMISE OF THE STUDY:Microsatellite markers were developed for the species Haumania danckelmaniana (Marantaceae) from central tropical Africa. METHODS AND RESULTS:Microsatellite isolation was performed simultaneously on three different species of Marantaceae through a procedure that combines multiplex microsatellite enrichment and next-generation sequencing. From 80 primers selected for initial screening, 20 markers positively amplified in H. danckelmaniana, of which 10 presented unambiguous amplification products within the expected size range and eight were polymorphic with four to nine alleles per locus. Positive transferability with the related species H. liebrechtsiana was observed for the same 10 markers. CONCLUSIONS:The polymorphic microsatellite markers are suitable for studies in genetic diversity and structure, mating system, and gene flow in H. danckelmaniana and the closely related species H. liebrechtsiana.
