1. Resistance of cocoa to Moniliophthora perniciosa – progenitors and progenies selection
ABSTRACT Witches' broom, caused by Moniliophthora perniciosa, is the most important cacao disease in Brazil, and the final objective of this study is increasing the level and durability of resistance to this fungus, through the association of different alleles or genes favorable to the character, for the generation of new cocoa varieties. It was conducted, f

2. Selection strategies in a segregating passion fruit population aided by classic and molecular techniques
ABSTRACT Combining the use of agronomic, disease-resistance, and molecular informationcan greatly contribute to genetic progress in breeding programs. This study was developed to estimate the genetic distance between genotypes derived from backcrosses and their parents using morphoagronomic and molecular information and information pertaining to resistance t

3. 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

4. THE INFLUENCE OF ACE I/D GENE POLYMORPHISM IN AMATEUR AMERICAN FOOTBALL ATHLETES IN BRAZIL
RESUMO Introdução O desempenho físico depende de uma série de propriedades biológicas e mecânicas. Esses diferentes fenótipos são relacionados através da complexa interação entre o ambiente e o perfil genético individual. A hipótese é que existe um componente hereditário que interfere na aptidão física. O gene da ECA destaca-se entre os ge

6. Genetic variability of tambaqui broodstocks in the Brazilian state of Pará
ABSTRACT The present study evaluated the genetic variability of the broodstocks of tambaqui hatcheries in the Brazilian state of Pará. Samples were obtained from the caudal fin of 110 broodstocks from one hatchery in each of four municipalities (Santarém, Peixe-Boi, Breu-Branco, and Ulianópolis), representing all the individuals of each hatchery stock.

7. Diversidade e estrutura genética de populações de Podocarpus lambertii Klotzsch ex Endl. na floresta ombrófila mista em Santa Catarina
Resumo Podocarpus lambertii (Podocarpaceae) é conhecido popularmente como pinheiro-bravo. Ocorre em várias formações florestais da Mata Atlântica, principalmente na Floresta Ombrófila Mista. Devido à intensa exploração madeireira sofrida pela espécie, ela está presente na categoria “Quase ameaçada” da Lista Vermelha das Espécies Ameaçadas d

8. Association between MBL2 haplotypes and dengue severity in children from Rio de Janeiro, Brazil
BACKGROUND Dengue is an arthropod-borne viral disease with a majority of asymptomatic individuals and clinical manifestations varying from mild fever to severe and potentially lethal forms. An increasing number of genetic studies have outlined the association between host genetic variations and dengue severity. Genes associated to viral recognition and ent

9. Discovery and characterization of SSR markers in Eugenia uniflora L. (Myrtaceae) using low coverage genome sequencing
Abstract: Eugenia uniflora L. (Myrtaceae) is a tree species widely distributed in South America suffering the effects of the exploitation of natural populations. In this study, we employed low coverage sequencing of the E. uniflora genome for mining of SSR markers. The de novo assembly generated 2,601 contigs with an average length of 1139 bp and spans 3.15

10. Evaluation of insecticide resistance in Aedes aegypti populations connected by roads and rivers: the case of Tocantins state in Brazil
BACKGROUND The longstanding application of insecticides for vector control without periodic monitoring of the population response to these chemicals can directly drive the selection of resistant populations of vector mosquitoes. Tocantins is the newest state of the Brazilian Federation. Despite a historically high number of dengue cases, studies and monito

11. 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

12. Lack of quadruple and quintuple mutant alleles associated with sulfadoxine-pyrimethamine resistance in Plasmodium vivax isolates from Brazilian endemic areas
BACKGROUND AND OBJECTIVE Brazil is responsible for a large number of Plasmodium vivax cases in America. Given the emergence of P. vivax parasites resistant to chloroquine and the effectiveness of antifolates in vivax malaria treatment together with a correlation between mutations in P. vivax dhfr and dhps genes and SP treatment failure, the point mutations
