Genetic variability; Microsatellites; Molecular characterization; Musa spp

Microsatellite markers have been widely used in the quantification of genetic variability and for genetic breeding in Musa spp. The objective of the present study was to evaluate the discriminatory power of microsatellite markers derived from ‘Calcutta 4’ and ‘Ouro’ genomic libraries, and to analyze the genetic variability among 30 banana accessions. Thirty-eight markers were ... more

Genetic control; Phaseolus vulgaris L.; Plant architecture; Repeatability

Cultivars of common bean with more erect plant architecture and greater tolerance to degree of lodging are required by producers. Thus, to evaluate the potential of hypocotyl diameter (HD) in family selection for plant architecture improvement of common bean, the HDs of 32 F2 plants were measured in 3 distinct populations, and the characteristics related to plant architecture ... more

Genetic control; Hybrid combination; OCC; SCC; Vigna unguiculata

The purpose of this study was to identify parents and obtain segregating populations of cowpea (Vigna unguiculata L. Walp.) with the potential for tolerance to water deficit. A full diallel was performed with six cowpea genotypes, and two experiments were conducted in Teresina, PI, Brazil in 2011 to evaluate 30 F2 populations and their parents, one under water deficit ... more

Expressiveness; Genetic control; Glycine max; Hilum aspect; Seed coat

Focusing on the genetic traits, seed coat and hilum pigmentation, in soybeans destined for human consumption is necessary due to the relevance of these traits for product acceptability by the consumer market. We investigated the traits seed coat, hilum color and bleeding hilum, in F2:3 populations originating from crosses between the soybean grain type ... 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 differentiation; Genetic diversity; Genetic structure; Myzus persicae nicotianae; Parthenogenesis

The tobacco aphid, Myzus persicae nicotianae (Hemiptera: Aphididae), is an important agricultural pest that feeds on host plants and transmits plant viruses in China. To effectively control this pest, we investigated the genetic variation and genetic structure of 54 populations of tobacco aphids collected in China, using five microsatellite loci. An average of 7 alleles with effective ... 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

Large yellow croaker; Larimichthys crocea; Microsatellites; Polymorphism

The large yellow croaker (Larimichthys crocea) is one of the largest marine net-cage cultured species in the oceans around China. In the present study, we isolated and characterized 13 polymorphic microsatellite markers from genomic libraries of L. crocea. Loci were screened for 10 wild specimens from 2 sites in southeast of China. All loci were polymorphic. The number of ... 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

The wrinkled frog, Rana rugosa, is a species complex that inhabits plains and mountains near freshwater bodies throughout East Asia, encompassing China, Korea, Japan, and the Russian Primorye region. Although extensive efforts are required to estimate cryptic diversity in the R. rugosa complex, no specifically designed microsatellite loci are available. Here, novel and ... more
