1. Optimized protocol to isolate high quality genomic DNA from different tissues of a palm species
RESUMO A aplicação de técnicas moleculares para lidar com questões ecológicas e evolutivas requer DNA genômico de boa qualidade e quantidade. A qualidade do DNA isolado, no entanto, pode ser influenciada pelo tipo de tecido e pela maneira como a amostra foi conservada e manipulada. Portanto, personalizar protocolos para melhorar o isolamento do DNA e a

2. Cross-genera SSR transferability in cacti revealed by a case study using Cereus (Cereeae, Cactaceae)
Abstract The study of transferability of simple sequence repeats (SSR) among closely related species is a well-known strategy in population genetics, however transferability among distinct genera is less common. We tested cross-genera SSR amplification in the family Cactaceae using a total of 20 heterologous primers previously developed for the genera Arioca

3. New microsatellite loci for annatto (Bixa orellana), a source of natural dyes from Brazilian Amazonia
Abstract Annatto (Bixa orellana) is a tropical crop native to the Americas with Amazonia as the likely center of origin of domestication. Annatto is important because it produces the dye bixin, which is widely used in the pharmaceutical, food, cosmetic and textile industries. A total of 32 microsatellite loci were isolated from a microsatellite-enriched geno

4. DNA sampling from eggshells and microsatellite genotyping in rare tropical birds: Case study on Brazilian Merganser
Abstract This study shows that sampling maternal DNA from hatched and abandoned eggshells is a viable noninvasive strategy for studying the genetics of rare or endangered tropical birds, as exemplified here by the Brazilian Merganser (Mergus octosetaceus). Eighteen microsatellites were isolated from enriched libraries and nine heterologous loci from related

5. Music genetics research: Association with musicality of a polymorphism in the AVPR1A gene
Abstract Musicality is defined as a natural tendency, sensibility, knowledge, or talent to create, perceive, and play music. Musical abilities involve a great range of social and cognitive behaviors, which are influenced by both environmental and genetic factors. Although a number of studies have yielded insights into music genetics research, genes and biolo

6. The use of microsatellite markers in Neotropical studies of wild birds: a literature review
ABSTRACT Despite extensive habitat fragmentation, the Neotropical region possesses 30% of the world´s bird species. Microsatellites have remained one of the most popular genetic markers and have been used in ecological and conservation studies since the 1990’s. We conducted a literature review comparing the number of papers published from January 1990 to

7. Microsatellite markers: what they mean and why they are so useful
Abstract Microsatellites or Single Sequence Repeats (SSRs) are extensively employed in plant genetics studies, using both low and high throughput genotyping approaches. Motivated by the importance of these sequences over the last decades this review aims to address some theoretical aspects of SSRs, including definition, characterization and biological functi

8. Gene variation and genetic differentiation among populations of the solitary mud dauber wasp Trypoxylon (Trypargilum) albitarse Fabricius 1804 (Hymenoptera, Crabronidae)
Abstract Trypoxylon is a genus of solitary crabronid wasps whose population genetics is poorly known. The purpose of the present study was to investigate the genetic variation and differentiation among five populations of Trypoxylon albitarse, a species widely distributed throughout the Neotropics, with records from Panama to northern Argentina. Eight specie

9. Chromosomal localization of microsatellite loci in Drosophila mediopunctata
Drosophila mediopunctata has been used as a model organism for genetics and evolutionary studies in the last three decades. A linkage map with 48 microsatellite loci recently published for this species showed five syntenic groups, which had their homology determined to Drosophila melanogaster chromosomes. Then, by inference, each of the groups was associated

10. Cross-species amplification of microsatellite loci developed for Passiflora edulis Sims. in related Passiflora Species
The aim of this study was to evaluate the selected 41 SSR markers developed for yellow passion fruit (Passiflora edulis f. flavicarpa Sims.) for their transferability to 11 different Passiflora species. Twenty-one SSR were successfully amplified in 10 wild species of passion fruit producing 101 bands. All the markers were amplifiable for at least one species

11. Mantel test in population genetics
The comparison of genetic divergence or genetic distances, estimated by pairwise F ST and related statistics, with geographical distances by Mantel test is one of the most popular approaches to evaluate spatial processes driving population structure. There have been, however, recent criticisms and discussions on the statistical performance of the Mantel test

12. Mapa genético-molecular para Hevea brasiliensis e mapeamento de QTL s para características de impotância econômica / Genetic linkage map for H. brasiliensis and QTL s mapping for important economic traits
A seringueira é uma espécie de cruzamento misto e com um longo ciclo de vida, o que dificulta a geração de linhagens endogâmicas e, por consequência, a construção e integração de mapas de ligação usando as metodologias convencionais. A exemplo do que tem sido feito em outras espécies vegetais que apresentam limitações para a obtenção de linh
