COI; Genetic diversity; MpnDV; Myzus persicae nicotianae

We previously described a novel densovirus [Myzus persicae nicotianae densovirus (MpnDV)] infecting M. persicae nicotianae (Hemiptera: Aphididae) with 34% prevalence. This single-stranded DNA virus has a 5480-nucleotide ambisense genome and belongs to the Densovirinae subfamily within the family Parvoviridae. In the present study ... more

Genetic diversity; Genetic variation; Mutagenesis; Mutation breeding; Oryza sativa

We studied the genetic variability due to mutation induced by γ-rays (10, 15, and 20 Kr) on various traits of twelve rice genotypes. Mutated and non-mutated seeds were sown in the field between July 2013 and 2014 using a split plot design. Yield and yield-related trait data was recorded, which showed significant (P < 0.05) genotypic and irradiation effects. Gamma radiation exerted non- ... more

Chinese fir; Genetic differentiation; Genetic diversity; Molecular marker; Red-colored heartwood

The present study investigated the genetic characterization of red-colored heartwood Chinese fir [Cunninghamia lanceolata (Lamb.) Hook.] in Guangxi using 21 simple sequence repeat (SSR) markers and analyzes of the genetic variation (N = 149) in samples obtained from five sites in Guangxi Province, China. The number of different alleles and the Shannon’s information index per ... more

Genetic distance; Genetic diversity; Genetic similarity; Genetic structure; Microsatellite; Siniperca chuatsi

In order to provide genetic information for the selective breeding of Siniperca chuatsi, 14 microsatellite DNA loci were used to evaluate the genetic diversity and structure of four farmed populations and one wild population in China. The four cultivated populations were Foshan (FS), Jiangmen (JM), Nanjing (NJ), and Hongze Lake (HZL), and the wild population was collected from the ... 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

Animals; Aphids; Biological evolution; Genetic variation; Hemiptera; Parthenogenesis; Photoperiod; Reproduction, Asexual; RNA; Transcriptome

Chinese galls form on sumac plants (Rhus chinensis) and are used for medicinal and chemical purposes, due to their richness in tannins. The galls are formed by aphids, the most prominent of which is Schlechtendalia chinensis, which forms horn-shaped galls on the winged rachis of R. chinensis. S. chinensis has a complex life cycle, including both R. chinensis and certain mosses as hosts, as ... more

Genetic control; Genetic differentiation; Gerbil; Microsatellites; Population variation

Although gerbils have been widely used in many areas of biological research over many years, there is currently no effective genetic quality control system available. In the present study, we sought to establish a microsatellite marker system for quality control and con­ducted an optimized analysis of 137 microsatellite loci in two labora­tory gerbil populations and one wild population. ... more

Chinese sucker; Conservation; Genetic differentiation; Microsatellite; Population structure

Studies of genetic diversity and genetic population structure are critical for the conservation and management of endangered species. The Chinese sucker Myxocyprinus asiaticus is a vulnerable monotypic species in China, which is at a risk of decline owing to fluctuations in effective population size and other demographic and environmental factors. We screened 11 microsatellite ... more

Conservation strategy; Genetic structure; Inter-simple sequence repeat; Wild soybean

Knowledge of the spatial patterns of genetic variation in wild populations has significant implications for in situ conservation and the determination of conservation order. To study the levels of genetic diversity, spatial genetic structures, and genetic distances in Glycine soja, 11 natural populations in northern China were analyzed by estimating genetic coefficients ... more

Cross-amplification; Genetic structure; Microsatellite loci; Taxus wallichiana var. wallichiana

Nine polymorphic microsatellite loci were isolated and characterized in Taxus wallichiana var. wallichiana, an endangered species in China. The number of alleles per locus ranged from 2 to 20. Observed and expected heterozygosities varied from 0.0260 to 0.5325 and 0.3603 to 0.9231, respectively. Positive cross-amplification of the 9 loci was observed in 2 other varieties ... more
