AFLP; Cactus; Genetic diversity; Semiarid region; Xiquexique

Amplified fragment length polymorphism (AFLP) analysis was used to evaluate DNA polymorphism in Pilosocereus gounellei with the aim of differentiating samples grown in different Brazilian semiarid regions. Seven primer pairs were used to amplify 703 AFLP markers, of which 700 (99.21%) markers were polymorphic. The percentage of polymorphic markers ranged from 95.3% for the primer ... more

Capparis spinosa L.; Genetic diversity; Inter-simple sequence repeat

Capparis spinosa L. is an important medicinal species in the Xinjiang Province of China. Ten natural populations of C. spinosa from 3 locations in North, Central, and South Xinjiang were studied using morphological trait inter simple sequence repeat (ISSR) molecular markers to assess the genetic diversity and population structure. In this study, the 10 ISSR primers ... more

Atlantic Forest; Bromeliads; Genetic diversity; Inter-simple sequence repeat; Natural populations

Bromeliads are greatly represented in the Atlantic Forest, although many species are threatened with extinction owing to habitat fragmentation and intense extraction for ornamental purposes. Therefore, it is necessary to conduct studies generating knowledge about genetic diversity and the distribution of this diversity among and within natural populations to establish conservation strategies. ... more

Genetic diversity; Hawthorn; Principal component

One hundred and six accessions of hawthorn intraspecific resources, from the National Germplasm Repository at Shenyang, were subjected to genetic diversity and principal component analysis based on evaluation data of 15 fruit traits. Results showed that the genetic diversity of hawthorn fruit traits varied. Among the 15 traits, the fruit shape variable coefficient had the most obvious ... more

Forage crop; Genetic diversity; ISSR markers; Molecular characterization

Cratylia argentea (Desv.) Kuntze (Fabaceae) is a drought-tolerant, perennial legume found primarily in Brazil, Bolivia, and Peru. The shrub is well adapted to acid soils and exhibits high productivity and nutritional value, characteristics that would favor its use as a dry season animal forage supplement in semiarid regions. In plant improvement programs, the production of elite ... more

Bellamya; Genetic diversity; Microsatellite markers; Population genetics

Bellamya is a widely distributed freshwater snail genus in China; however, its genetic diversity is completely unknown. Sixty-five novel microsatellite loci were isolated and characterized from a microsatellite-enriched library of Bellamya aeruginosa genomic DNA. Most of the 65 loci were successfully amplified. We found high polymorphic information content values for these loci, ... more

cluster analysis; Genetic diversity; Gossypium arboreum L.; Simple sequence repeat

Simple sequence repeat techniques were used to identify the genetic diversity of 101 Gossypium arboreum accessions collected from India, Vietnam, and the southwest of China (Guizhou, Guangxi, and Yunnan provinces). Twenty-six pairs of SSR primers produced a total of 103 polymorphic loci with an average of 3.96 polymorphic loci per primer. The average of the effective number of ... more

Gekko japonicus; Genetic diversity; Microsatellite; Polymorphism

Twelve polymorphic microsatellite loci were isolated in the Japanese gecko, Gekko japonicus. We genotyped one population from Wenzhou, Zhejiang Province, China (N = 36). The mean number of observed alleles per locus was 7.3 (range 4 to 13). Observed and expected heterozygosity values ranged from 0.200 to 0.944 and from 0.395 to 0.797, respectively. One locus (GJ20) showed ... more

DNA marker; Genetic diversity; Microsatellite; Syzygium samarangense

Syzygium samarangense (Blume) Merr. & Perry (wax apple) is an important commercial fruit tree in Southeast Asia. Here, microsatellite markers were developed to evaluate genetic diversity and distinguish cultivars in this species. In total, 161 microsatellite loci with sufficient flanking sequences to design primer sets were isolated from wax apple using a magnetic bead- ... more

Genetic diversity; Haplo-block structure; SNPs; Village chickens

This study investigated the haplo-block structure, haplotype sharing, and diversity in extensively raised chicken populations of Southern Africa. Two hundred ninety village chickens from Malawi (N = 30), South Africa (N = 132), and Zimbabwe (N = 128) were included in the study, from which 649, 2104, and 2442 haplo-blocks were observed, respectively. The majority of haplo-blocks were ... more
