Amplified fragment length polymorphism markers were used to assess genetic diversity in 10 male sterile wheat crop lines (hetero-cytoplasm with the same nucleus) in relation to a restorer wheat line. These male sterile lines were evaluated using 64 amplified fragment length polymorphism primer combinations, and 13 primers produced polymorphic bands, generating a total 682 fragments. Of ... more

Association analysis; Genetic diversity; Growth traits; Mandarin fish; Microsatellite

Mandarin fish (Siniperca chuatsi) is a traditionally cultured freshwater fish with high commercial value in China. To facilitate marker-assisted selection for genetic improvement of this species, 100 microsatellite markers identified in previous studies were characterized in the 25 largest and 25 smallest individuals. Twenty polymorphic loci were used to genotype 200 individuals ... more

Conservation; Endangered species; Genetic diversity; Simple-sequence repeat; Wild Prunus cerasifera

Simple-sequence repeat (SSR) markers were employed to assess the genetic diversity of wild Prunus cerasifera Ehrhart (wild cherry plum) in China. Fourteen SSR primer pairs generated a total of 94 alleles (90 were polymorphic, accounting for 95.74%), with a mean of 6.71 alleles per locus. The number of alleles detected at each locus ranged from 2 at BPPCT 028 to 13 at BPPCT 002, ... more

Acipenser schrenckii; Genetic diversity; Microsatellite; Next-generation sequencing; Polymorphism

Anthropogenic activities have seriously impacted wild resources of the Amur sturgeon, Acipenser schrenckii, and more infor­mation on local and regional population genetic structure is required to aid the conservation of this species. In this study, we report the develop­ment of 12 novel polymorphic microsatellite loci using next-generation sequencing technology, and the genotyping of ... more

Genetic diversity; Genetic structure; Lonicera macranthoides; SCoT

Lonicera macranthoides is an important traditional Chinese herb. The lack of information regarding the genetic structure and genetic relationships among its cultivars has hindered the conservation and utilization of this resource. This study used start codon targeted markers to assess the genetic diversity and other genetic characteristics of five single-variety L. macranthoides ... more

Eucommia ulmoides Oliver, the only extant species of Eucommiaceae, is a second-category state-protected endangered plant in China. Evaluation of genetic diversity among some intraspecific hybrid populations of E. ulmoides Oliver is vital for breeding programs and further conservation of this rare species. We studied the genetic diversity of 130 accessions from 13 E. ... more

Genetic diversity; Marker-trait association; Population structure; SSR marker; Waxy and normal maize inbred line

Understanding genetic diversity, population structure, and linkage disequilibrium is a prerequisite for the association mapping of complex traits in a target population. In this study, the genetic diversity and population structure of 40 waxy and 40 normal inbred maize lines were investigated using 10 morphological traits and 200 simple sequence repeat (SSR) markers. Based on a population ... more

Endemic species; Genetic diversity; Pinus krempfii; Population structure; SSR markers

Pinus krempfii Lecomte (Pinaceae) is an endemic tree to Vietnam with restricted habitats at higher altitudes in the highlands. In this study, genetic variation of four populations of P. krempfii was assessed using 17 microsatellite markers (single sequence repeats). Of these 17 markers, eight were polymorphic, and among the 42 putative alleles amplified, 32 were polymorphic ( ... more

Chloroplast genome; Genetic diversity; Ginkgo biloba; Microsatellites

Ginkgo biloba is considered to be a living fossil that can be used to understand the ancient evolutionary history of gymnosperms, but little attention has been given to the study of its population genetics, molecular phylogeography, and genetic resources assessment. Chloro­plast simple sequence repeat (cpSSR) markers are powerful tools for genetic studies of plants. In this study ... more

Genetic diversity within Vicia faba L. is key to the ge­netic improvement of this important species. In this study, morphologi­cal traits and RAPD molecular markers were used to assess the levels of polymorphism across 12 Tunisian populations, three major and nine minor from different locations. Analysis of morphological traits indi­cated that the three major ... more
