Abstract: Using polymorphic loci of allozyme as genetic marker and horizontal sliceable gel electrophoresis as method to examine the genotypes of 4 Bruguiera gymnorrhiza populations in Fugong of Fujian (24°24′), Futian of Guangdong (22°32′), Shankou of Guangxi (21°28′) and Dongzhai Harbor of Hainan (19°51′), China. The mating system was also decided by Multi Locus Testing. The polymorphic loci ...

the crustacean paramysis intermedia is one of the most important zooplanktons which is used as food by aquatic animals in estuaries and marine environments. regarding the existence of this zooplankton stocks in the persian gulf and oman sea, knowledge on genetic structure of this species is necessary for conservation of its biological diversity and gene pool. in present study, genetic diversity...

The sea cucumber Holothuria scabra is an endangered species. In this study, nine new polymorphic microsatellite loci were developed and tested in 30 individuals. The number of alleles ranged from 2 to 5, and the observed and expected heterozygosities ranged from 0.1200 to 0.7391 and from 0.2408 to 0.5983, respectively. No loci significantly deviated from the Hardy-Weinberg equilibrium af-ter a ...

Three Iranian native strains and three Japanese commercial lines of the silkworm Bombyx mori were analyzed using amplified fragment length polymorphism (AFLP) markers. A set of ten PstI/TaqI primer combinations amplified a total of 322 bands out of which 251 (%78) were polymorphic. Estimates of Nei’s gene diversity for all loci in individual strains and commercial lines indicated a higher degre...

UNLABELLED PREMISE OF THE STUDY Nine polymorphic and 12 monomorphic microsatellite loci (simple sequence repeats [SSRs]) were isolated and characterized for the gynodioecious grassland perennial Saxifraga granulata. • METHODS AND RESULTS Based on genomic screening of leaf material of four individuals from four populations, a total of 21 microsatellite primer pairs were designed for S. gran...

Ulmus pumila is an elm species, non-native to the USA that hybridizes with Ulmus rubra. In order to study the genetic structure and hybridization patterns between these two elm species, we developed 15 primer pairs for microsatellite loci in U. rubra and tested their cross-amplification in U. pumila. All 15 primers amplified in both species, 11 of which possessed species-specific alleles. Eight...

We have summarized the frequency and distribution of the rare variants encountered during the screening of 258,815 allele products, the products of 51 different loci, in 3242 predominantly Caucasian (88%) newborns. Seventy-nine different rare variants, representing 187 occurrences, were identified. Almost 60% (46 of 79) of the rare variants occurred as singletons while another 20% were seen in ...

This study was conducted in order to investigate genetic diversity and population structure of pike-perch in the Northern part of Iran. For this purpose, 207 adult pike-perches from four regions of the Caspian Sea watershed (Talesh Coasts, Anzali Wetland, Chaboksar Coasts and Aras Dam) were collected. DNA was extracted and by using 15 pairs of microsatellite primers, Polymerase Chain Reaction (...

Seven polymorphic microsatellite markers were developed and validated for Bertholletia excelsa (Brazil nut tree) population genetic studies. This species is a widespread monotypic Amazonian tree with high non-timber economic value. Unfortunately, Brazil nut production is currently less than 25% of historical production levels, because of extensive deforestation. All pairs of primers produced cl...

Eleven novel polymorphic microsatellite loci were developed and characterized for the recently validated roundscale spearfish Tetrapturus georgii. Characterization of these markers, based on 35 roundscale spearfish from the western North Atlantic, revealed two to 21 alleles per locus with an average expected heterozygosity (H(E) ) of 0·09-0·94, and all loci conformed to Hardy-Weinberg expectati...
