1. Fruit quality and genetic diversity of Spondias dulcis accessions
ABSTRACT Among the less exploited Brazilian native fruit trees, the Spondias dulcis (cajá-manga) has many uses, being their fruits appreciated in fresh consumption and its pulp used in popsicles, ice-creams, and jellies production. However, there is a lack of research on this species, being necessary more studies. This work aimed to characterize the physica

2. Selection in segregating populations of ornamental pepper plants (Capsicum annuum L.) using multidimensional scaling
ABSTRACT Multidimensional scaling is a multivariate analysis technique that can be used to exploit genetic diversity, aiming at the selection of Capsicum genotypes with desirable characteristics for in-pot ornamental purposes. This work aimed to select genotypes with ornamental potential within F4 populations of ornamental pepper plants. Three F4 families we

3. Genetic diversity in F3 population of ornamental peppers (Capsicum annuum L.)
ABSTRACT Peppers belong to the Solanaceae family and present a wide genetic variability that may be accessed through phenotypic and genotypic traits. This work aimed to study the genetic divergence in an ornamental pepper F3 population by multivariate methods based on the individual and simultaneous analyses of qualitative, quantitative, and molecular data.

4. Evaluation of production and quality traits in interspecific hybrids of ornamental pepper
RESUMO O cultivo de pimentas em vaso como planta ornamental tem aumentado consideravelmente em todo o planeta. No Brasil, esse cultivo é mais recente e ainda carece de cultivares. Para ampliar a variabilidade disponível e obter novas cultivares, a hibridação interespecífica é muito útil como forma de inserir um atributo desejável que ocorre em uma es

6. ENDOPHYTIC FUNGI FROM THE BRAZILIAN FLORA AND THEIR EMPLOYMENT IN BIOTRANSFORMATION REACTIONS
The biotransformation reactions are used as a successful alternative to derivatization by the traditional chemistry because they conduct to uncommon reactions, which would hardly be carried out by chemical synthesis. A wide diversity of compounds may be metabolized by fungi, leading to chemical derivatives through selective reactions that work under ecofrien

7. Genetic evidence of multiple reproductive strategies in a microendemic and threatened cactus (Cactaceae: Discocactus Pfeiff) in Bahia, Brazil
ABSTRACT Discocactus zehntneri subsp. petr-halfari, an endangered taxon, is represented by a single population in an anthropized area of Bahia, Brazil, where it is suffering due to extreme extractivism. Thus, information about this cactus, such as its reproductive patterns, is urgently needed to support conservation strategies. A population genetics approach

8. Genetic diversity among red mombin fruits in the Southwest of Goiás
ABSTRACT The identification of productive plants with fruits of desirable characteristics contributes to the optimization of commercial crops of red mombin fruits. The aim of this work was to evaluate the genetic diversity among the provenance of red mombin of two municipalities of the state of Goiás. The fruits were harvested at ripening stage 3 and transp

9. From ecosystems to human welfare: the role and conservation of biodiversity
RESUMO: A biodiversidade desempenha um papel fundamental no bem-estar humano, proporcionando benefícios agrícolas, econômicos e de saúde. No entanto, após a revolução industrial, a rápida expansão da população humana e as subsequentes atividades econômicas provocaram uma perda drástica na biodiversidade global, resultando em perturbações sign

10. Biometry and genetic diversity of paradise nut genotypes (Lecythidaceae)
Resumo: O objetivo deste trabalho foi avaliar a biometria de frutos e sementes e a diversidade de genótipos de sapucaia (Lecythis pisonis). Frutos de 12 genótipos de sapucaia foram coletados de plantas na região norte do Estado do Espírito Santo e leste do Estado de Minas Gerais. Os dados foram submetidos à análise de variância, e as médias dos difer

11. Molecular characterization of a phytoplasma associated with a commercial variety of Momordica charantia
ABSTRACT: Momordica charantia (bitter melon) presents two distinct types or varieties, known as wild type and commercial type. Plants of the wild type are hosts of a phytoplasma of the group 16SrIII-J, which is associated with a disease known as witches’ broom. However, this disease has not yet been reported in commercial bitter melon. Thus, symptomatic pl

12. Can the reproductive system of a rare and narrowly endemic plant species explain its high genetic diversity?
ABSTRACT The reproductive system of flowering plants can be highly variable, affecting their biology, gene flow and genetic variability among populations. Petunia secreta is a rare annual endemic species of Pedra do Segredo, located in the municipality of Caçapava do Sul, state of Rio Grande do Sul, Brazil. Although rare, the species possesses a high level
