Sipunculus nudus, the peanut worm, is the best known species in its genus. This unsegmented subtidal marine worm is consumed in some parts of Asia and is also used as fish bait. We found 20 microsatellite DNA markers for S. nudus. The number of alleles per polymorphic locus ranged from two to seven in a sample of 39 individual.. Read More»

The marbled rockfish, Sebastiscus marmoratus, is an important commercially near-shore fish that inhabits the beach rocky bottom from Japan to the South China Sea. Eleven polymorphic microsatellite loci were developed from S. marmoratus and were used to identify polymorphisms in 30 samples from a wild population. The allele locus number ranged from 2 to 7. Po..

The fragments of the Atlantic Forest of southern Bahia have a long history of intense logging and selective cutting. Some tree species, such as jequitibá rosa (Cariniana legalis), have experienced a reduction in their populations with respect to both area and density. To evaluate the possible effects of selective loggin.. Read More»

Many species are expected to suffer strong shifts in their geographic ranges due to climate changes in the next 50 years, with severe consequences for biodiversity patterns and population structure. We used here an ensemble forecast approach for obtaining species’ range in which multiple species distribution models and c.. Read More»

The aim of the present article was to study the population structure and genetic diversity of Nelore cattle and genetic relationships between Nelore and different taurine and zebu breeds raised in Brazil. DNA polymorphism analysis was carried out with 1976 animals of 16 zebu, taurine and synthetic breeds raised in Brazil. A higher genetic differentiation .. Read More»

In this study, we analyzed the genetic diversity and structure of remnants of mangaba populations in states of northeastern Brazil by applying 9 microsatellite markers previously developed to establish conservation strategies for germplasm and species preservation. Six to 20 individuals per population were analyzed, with a total of 94 individuals and 6 po.. Read More»

The main objective of a maize breeding program is to generate hybrid combinations that are more productive than those pre-existing in the market. However, the number of parents, and consequently the number of crosses, increases so rapidly that the phenotypic evaluation of all the possible combinations becomes economically and technically infeasible. In th.. Read More»

We isolated and characterized 22 polymorphic microsatellite loci in the crimson snapper (Lutjanus erythropterus) using a (GT)13-enriched genomic library. We found three to 15 alleles per locus, with a mean of 6.68. The observed and expected heterozygosities ranged from 0.087 to 0.978 and from 0.125 to 0.904, respectively, with averages of 0.576 and 0.650,.. Read More»

Microsatellite primers were developed and optimized for Lippia alba to characterize the L. alba germplasm bank of Universidade de S?£o Paulo. A genomic library enabled the design of 9 microsatellite primers. Six of the 9 primers yielded polymorphic products, which defined 2 groups in the bank. The data provide support to characterize germplasm banks, genet.. Read More»

We described five novel microsatellite loci for the piracema fish species Prochilodus lineatus (Characiformes), endemic to South America and of extreme importance to both commercial and artisanal fisheries across its occurrence area. A primary, unenriched genomic library was constructed and radioactively screened for repetitiv.. Read More»
