We present polymorphic microsatellite markers isolated for genetic studies of the sugarcane borer, Diatraea saccharalis (Fabricius). We isolated 16 microsatellite loci through an enriched genomic library protocol. After characterization, 12 markers showed polymorphic information expressed in the observed number of alleles (ranging from 2 to 7; 5 on average) and in the ... more
Wild Dipsacus chinensis plants in China have become endangered owing to over-harvesting and habitat fragmentation. We examined the genetic diversity and genetic structure of 90 individuals from three populations using inter-simple sequence repeat markers and found that 106 of 173 bands amplified by 22 informative and reliable primers were polymorphic. These findings correspond to ... more
Genetic diversity and structure were analyzed in 10 accessions belonging to Banco Ativo de Germoplasma de Capsicum located at Federal University of Piauí in northwestern Brazil that receives pepper samples grown in community gardens in various regions and Brazilian states. Selections were made from seeds of C. chinense (4 accessions), C. annuum (5 accessions), ... more
We analyzed population structure and genetic diversity in Blanco Orejinegro Creole cattle with 12 microsatellite markers, genotyping 138 individuals belonging to 7 commercial and 3 conservation herds. These markers showed a high level of polymorphism; 171 alleles were identified. The mean number of alleles per locus was 5.63 (3.82-6.58). The total number of alleles per marker was 14.2 and ... more
Dahurian larch (Larix gmelinii), a deciduous conifer, is the northernmost tree, native to eastern Siberia and nearby regions of China. We used growth traits and molecular markers to assess genetic variation in different L. gmelinii growing regions; 105 individual samples were collected from seven regions of the Qingshan Forestry Centre, Heilongjiang Province, China. The ... more
Researchers have classified the Heliconia genus as a group of highly variable and diverse plants. Species and cultivars are visually differentiated primarily on the basis of the color and size of inflorescence bracts. At taxonomic level, flower type (parabolic, sigmoid, or erect) and size are taken into account. The vast morphological diversity of heliconias at intra-specific, ... more
Phytophthora capsici is a plant pathogenic oomycete that damages numerous crops worldwide. Consequently, interest in research on the genetic structure of this species has grown in recent decades. However, there is little information about P. capsici in eastern China. We investigated the genetic diversity of P. capsici isolates from three large regions of Anhui ... more
The black locust (Robinia pseudoacacia) is a forest legume that is highly valued as a honey plant and for its wood. We explored the effect of short-term spaceflight on development of R. pseudoacacia seedlings derived from seeds that endured a 15-day flight; the genetic diversity and variation of plants sampled from space-mutagenized seeds were compared to plants from ... more
We used complex hypervariable repeats to evaluate the genetic diversity and structure of Prochilodus costatus (Characiformes), an ecologically and economically important species endemic to the São Francisco River basin. Hydroelectric dams along the river have led to population fragmentation, which can limit gene flow. Restocking from hatcheries has been used to repopulate ... more
Populations of the Pacific abalone, Haliotis discus hannai, have been severely overexploited over the past few decades in Korea. Information regarding the levels of genetic variability and structure within populations is insufficient for the development of effective strategies for conservation of genetic diversity of this species. To assess the genetic status of this species, we ... more
