1. Genetic diversity of eight wild populations of Pampus argenteus along the coast of China inferred from fifteen polymorphic microsatellite markers
Abstract Pampus argenteus (Perciformes: Stromateidae) is widely distributed along the coast of China, Indian Ocean, Arabian Gulf and North Sea. Due to overfishing and environmental degradation, its resources reduced year after year. Thus, new management strategies are urgently needed for the sustainable growth and utilization of this species. Characterizatio

2. Microsatellites for detecting inconsistencies in Capsicum cultivars registration in Brazilian database: more than meets the eye
RESUMO No Brasil, o registro de cultivares é feito com cadastramento no Registro Nacional de Cultivares (RNC), o qual, além de habilitar a comercialização do material propagativo da cultivar, garante ao produtor pureza e identidade genética dos propágulos. Mas, é possível que as informações fornecidas para o registro e comercialização das cultiva

3. Inferring mating system parameters in forage peanut, Arachis pintoi, for Brazilian Amazon conditions
RESUMO A busca por alternativas para aumentar a produtividade e a sustentabilidade da pecuária na região Amazônica sem aumentar o desmatamento é desafiadora. Pastagens consorciadas de gramíneas com amendoim forrageiro (Arachis pintoi) têm mostrado impactos econômicos positivos. Porém, lacunas no conhecimento da biologia reprodutiva do amendoim forrag

4. Genetic diversity in Calibrachoa pygmaea (Solanaceae): A hawkmoth-pollinated nightshade from the Pampas
ABSTRACT Calibrachoa pygmaea is a unique species of Calibrachoa, especially concerning its flower morphology and the environment where it occurs. The species is self-incompatible and is narrowly distributed in wet and flooded fields of the Pampas region. We characterize the genetic diversity of the species based on traditional plastid markers and newly devel

5. Liaisons dangereuses: cross-border gene flow and dispersal of insecticide resistance-associated genes in the mosquito Aedes aegypti from Brazil and French Guiana
BACKGROUND In recent years, South America has suffered the burden of continuous high impact outbreaks of dengue, chikungunya and Zika. Aedes aegypti is the main mosquito vector of these arboviruses and its control is the only solution to reduce transmission. OBJECTIVES In order to improve vector control it is essential to study mosquito population geneti

6. 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

7. Development and characterization of 20 polymorphic microsatellite markers for Epinephelus marginatus (Lowe, 1834) (Perciformes: Epinephelidae) using 454 pyrosequencing
Abstract The dusky grouper, Epinephelus marginatus, is a well-known and widespread marine fish assessed as endangered by the International Union for the Conservation of Nature. Analyzing the genetic diversity of this species is, therefore, of utmost importance and necessary for conservation purposes. Microsatellites are molecular tools with advantages that a

8. Molecular marker assisted selection for increasing inbreeding in S1 populations of cassava
Abstract The objective of the present work was to use MAS in self-pollinated cassava populations for obtaining individuals with high inbreeding (f) aimed at rapid development of partial inbred lines. Three progenies (F0222, F1378 and F1662) were self-pollinated, generating a total of 233 S1 individuals. The progenies and the S1 individuals were evaluated in

9. Genetic diversity in oil palm (Elaeis guineensis Jacq) using RAM (Random Amplified Microsatellites)
ABSTRACT The oil palm (Elaeis guineensis Jacq) plays an important role in the economy of some tropical countries; Colombia ranks first for production in Latin America and fifth in the world. The aim of this research was to characterize the genetic variability of 51 oil palm genotypes from the Congo with seven randomly amplified microsatellite markers RAM. As

10. Quantity, organization, and distribution of chloroplast microsatellites in all species of Eucalyptus with available plastome sequence
Abstract In this study, we quantify and document the distribution and organization of cpSSRs in the chloroplast genome of 31 Eucalyptus species. Our sample included all previously sequenced plastomes of Eucalyptus species available from the NCBI online database. We processed the complete cpDNA sequences and identified mono-, di-, tri-, tetra-, penta-, and he

11. Repetitive DNAs and shrink genomes: A chromosomal analysis in nine Columbidae species (Aves, Columbiformes)
Abstract An extensive karyotype variation is found among species belonging to the Columbidae family of birds (Columbiformes), both in diploid number and chromosomal morphology. Although clusters of repetitive DNA sequences play an important role in chromosomal instability, and therefore in chromosomal rearrangements, little is known about their distribution

12. 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
