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; Morphological traits; RAPD; Tunisian populations; UPGMA analysis; Vicia faba L.

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

Genetic diversity; Germplasm resources; iPBS molecular markers; Paeonia suffruticosa Andrews

We examined the genetic diversity of 10 wild species (populations) and 55 varieties of tree peony using inter-primer binding site (iPBS) markers. From a total of 36 iPBS primers, 16 were selected based on polymorphic amplification. The number of bands amplified by each primer ranged from 9 to 19, with an average of 12.88 bands per primer. The length of bands ranged from 100 to 2000 bp, ... more

EST-SSR markers; Genetic diversity; Reciprocal recurrent selection; Zea mays

This study aimed to improve grain yield in the full-sib reciprocal recurrent selection program of maize from the North Flumi­nense State University. In the current phase of the program, the goal is to maintain, or even increase, the genetic variability within and among populations, in order to increase heterosis of the 13th cycle of reciprocal recurrent selection. Microsatellite ... more

Cucumber; Cucumis sativus L.; Fruit traits; Genetic diversity; Simple sequence repeat

The cucumber (Cucumis sativus L.) is an important crop grown worldwide. In this study, the genetic diversity of 42 cucumber cultivars in China was analyzed using 51 pairs of simple sequence repeat (SSR) primers. These primers identified 129 polymorphic loci, 95.6% of which were polymorphic. The mean effective number of alleles, mean Nei’s gene diversity, and mean Shannon’s ... more

Genetic diversity; Growth traits; Mandarin fish; Microsatellite

The mandarin fish (Siniperca chuatsi) is a traditionally cultured freshwater fish with high commercial value in China. To facilitate marker-assisted selection in genetic improvement of this species, 120 microsatellite markers from the literature were characterized in the 25 largest and 25 smallest individuals. Eighteen polymorphic loci were then used to genotype 200 individuals, ... more

AFLP; Amorphophallus konjac; Central China; Crop; Genetic diversity

Amorphophallus konjac is an economically important crop. In order to provide baseline information for sustainable development and conservation of the wild plant resources of A. konjac, we studied the genetic diversity and population structure of this species using amplified fragment length polymorphism (AFLP) molecular markers. We sampled 139 individuals from ... more

Genetic diversity; Neotropical fish; RAPD; Sedentary species

Most studies of diversity and genetic structure in neotropical fish have focused on commercial species from large rivers or their reservoirs. However, smaller tributaries have been identified as an important alternative migratory route, with independent pools of genetic diversity. In this context, the present study aimed to evaluate genetic diversity and structure in five neotropical fish ... more

Genetic diversity; Germplasm; ISSR; Morpho-agronomy; Perennial ryegrass; RAPD

Tunisia is rich in diverse forage and pasture species including perennial ryegrass. In order to enhance forage production and improve agronomic performance of this local germplasm, a molecular analysis was undertaken. Random amplified polymorphic DNA (RAPD), inter simple sequence repeats (ISSR) and morpho-agronomical traits markers were used for genetic diversity estimation of ryegrass ... more
