1. EVALUATION OF DIVERSITY AND GENETIC STRUCTURE AS STRATEGIES FOR CONSERVATION OF NATURAL POPULATIONS OF Dalbergia nigra (Vell.) Allemão ex Benth.
ABSTRACT: The evaluation of diversity and genetic structure allows us to verify with precision the effect of evolutionary and anthropic processes on species. The objective of this research was to evaluate the divergence and the genetic structure of two natural populations of Dalbergia nigra, using molecular markers Inter Simple Sequence Repeats (ISSR).

3. Genotyping and molecular analysis of transgenic sequences in chrysanthemum (Chrysanthemum X morifolium Ramat)
Abstract Genotypes of the chrysanthemum cultivars Harman and Indianapolis were transformed using Agrobacterium tumefaciens strain LBA4404, which carries the binary plasmid pBIN19::Rd29A::ScTPS1TPS2::nos and pBIN19::35S::ScTPS1TPS2::nos, respectively. ISSR markers were used to discriminate two cultivars from each other, and independent transgenic plants gener

4. AGRONOMIC POTENTIAL AND GENETIC DIVERSITY OF LANDRACES OF COWPEA OF THE STATE OF CEARÁ
RESUMO Variedades tradicionais são fontes de variabilidade genética, principalmente no que se refere a alelos que conferem tolerância a fatores bióticos e abióticos e, portanto, podem auxiliar os programas de melhoramento no desenvolvimento de cultivares promissoras. Contudo, torna-se necessário conhecer esse patrimônio genético em nível que permita

5. Genetic diversity and nonparametric statistics to identify possible ISSR marker association with fiber quality of pineapple
Abstract: Due to the increasing search for renewable resources, plant fibers have become an alternative when creating new products. Studies demonstrate the potential use of pineapple fibers in composites. The objective of this work was to evaluate the genetic diversity and verify any association between ISSR (Inter Simple Sequence Repeats) bands and quality

6. Diagnostic fingerprints ISSR/SSR for tropical leguminous species Stylosanthes capitata and Stylosanthes macrocephala
ABSTRACT: Stylosanthes capitata Vogel and Stylosanthes macrocephala M.B.Ferreira & Sousa Costa are two forage leguminous species of agronomic importance for animal husbandry in tropical environments. The physical mixture of both species (80 % S. capitata and 20 % S. macrocephala) comprises the commercial cultivar “Estilosantes Campo Grande”. However, pro

7. Genetic variability among cashew hybrids and prediction of superior combinations based on agronomic performance
Resumo: O objetivo deste trabalho foi avaliar o uso de marcadores moleculares RAPD e ISSR para determinar a variabilidade genética entre genótipos de cajueiro (Anacardium spp.) e indicar possíveis cruzamentos promissores com base na variabilidade genética e no desempenho fenotípico do cajueiro. Foram avaliados, em nível molecular, dez híbridos - origi

9. Micropropagation, plantlets production estimation and ISSR marker-based genetic fidelity analysis of Guadua magna and G. angustifólia
RESUMO Os bambus Guadua magna e G. angustifolia têm sido propagados vegetativamente quase que exclusivamente por técnicas convencionais de propagação. Objetivou-se micropropagar, estimar a produção de mudas e analisar a fidelidade genética de G. magna e G. angustifolia por marcadores moleculares ISSR. Plantas matrizes de ambas as espécies foram culti

10. Morphometric and molecular differences among Calvertius tuberosus (Coleoptera: Curculionidae) populations associated with Andean and coastal populations of Araucaria araucana in the La Araucanía Region, Chile
Abstract Calvertius tuberosus (Curculionidae) lives exclusively on Araucaria araucana trees (commonly known as pehuen) in southern Chile. In this study, morphometric and molecular genetic analyses of Andean and coastal populations of C. tuberosus were performed to evaluate evolutionary divergence associated with the discontinuity of the Araucaria forest betw

11. Molecular characterization of arabica and Conilon coffee plants genotypes by SSR and ISSR markers
The molecular characterization of ten genotypes of the Coffea arabica plants and of seven genotypes of C. canephora having interesting features for coffee breeding programs was carried to select the parents for breeding. A total of 40 SSR and 29 ISSR primers were used. The primers generated a total of 331 (307 polymorphic and 24 monomorphic) bands. Analysis

12. Diversity and genetic structure of jenipapo (Genipa americana L.) Brazilian accessions
Usually known as jenipapo, Genipa americana L. is a Rubiaceae Brazilian native species. It is an important species in the restoration of Brazilian riparian forests and is one of the most promising fruit trees for sustainable harvesting programs. In this study we provide the first data on the genetic diversity and structure of a Jenipapo Germplasm Bank using
