Bayes Theorem; Bertholletia; Gene flow; Genotype; Inbreeding; Microsatellite Repeats; Polymorphism, Genetic

The present study was carried out in a native Brazil nut tree population (Bertholletia excelsa Bonpl., Lecythidaceae) to assess its genetic diversity and structure. Ten microsatellite markers were used to genotype 198 adult trees (B. excelsa). The population presented high genetic diversity and inbreeding absence rates. The empirical Bayesian method showed three distinct groups in the ... more

Eucalyptus; Gene frequency; Genotype; Linkage disequilibrium; Microsatellite Repeats; Polymorphism, Genetic

Eucalyptus urophylla is an important species in the Brazilian forest sector due to its rapid growth rates and resistance to disease. The aim of this study was to verify Mendelian inheritance, genetic linkage, and genotypic disequilibrium for 15 microsatellite loci, with the goal of producing a robust set of genetic markers. Mendelian inheritance and genetic linkage analyses were carried out ... more

Alleles; Cucurbitaceae; Genotype; Heterozygote; Microsatellite Repeats; Polymorphism, Genetic

Taking into account the scenario of melon production (Cucumis melo L.) in Brazil, it is notable the importance of the culture in the fruit market. The preference of the national market is concentrated in the fruits of the yellow type. Therefore, it is possible that the genetic base of the commercial cultivars is relatively narrow due to the loss of important genes in the breeding process, and ... more

Anacardiaceae; Evolution, Molecular; Genotype; Heterozygote; Inbreeding; Microsatellite Repeats; Polymorphism, Genetic

Anacardium humile Saint Hilaire is a tropical shrub native to the Cerrado biome. It is a fruiting species with biological, medicinal, and socioeconomic significance. Thus, knowing how the genetic variability of natural populations is organized allows for the establishment of strategies for conservation and the sustainable use of the species and its biome. Six microsatellite loci previously ... more

Acute coronary syndrome (ACS) is considered one of the main causes of death worldwide. Contradictory findings concerning the impact of the angiotensin-converting enzyme (ACE) gene on cardiovascular diseases have been reported. Previous conclusions point out that the variability in results depends on ethnicity and genetic polymorphisms to determine the association of rs4340 polymorphisms of the ... more

Brazil; Coffea; Genotype; Multivariate analysis; Polymorphism, Genetic

For the selection of coffee plants that have favorable characteristics, it is necessary to evaluate variables related to production. Knowledge of the genetic divergence of arabica coffee is of extreme importance, as this knowledge can be associated with plant breeding programs in order to combine genetic divergence with good productive performance. The objective of this study was to evaluate ... more

Arachis; Genotype; Plant Leaves; Plant Proteins; Resveratrol; RNA, Messenger; Stilbenes; Tetraploidy; Transcriptional activation; Ultraviolet Rays

Resveratrol is an antioxidant that is a promising antitumoral, cardioprotective and neuroprotective agent. It has been found in a restricted number of plants including peanut (Arachis hypogaea L.) and its wild relatives. The objective of this study was to understand the relationship between resveratrol content and the expression of putative resveratrol synthase genes in four Arachis genotypes ... more

Chronic heart failure; Genotype; Glu298Asp; NOS3 gene; Polymorphism

The eNOS Glu298Asp (rs1799983) polymorphism of the NOS3 gene has been implicated as a risk factor for cardiovascular diseases; however, not all studies find significant associations. We examined this possibility in a Russian (Siberian) population. One hundred patients with chronic heart failure and 40 controls were investigated. PCR analysis was performed ... more

Endometriosis; eNOS; Genotype; Infertility; Polymorphism

Endometriosis is a chronic disease with adverse implications for fertility. We investigated the G894T polymorphism in the endothelial nitric oxide synthase gene in fertile and infertile women with endometriosis. This prospective study included a group of 52 women with a laparoscopic diagnosis of endometriosis. DNA was extracted from blood obtained from 47 patients ... more
