1. Cytogenetic characterization of Angelonia integerrima Sprengel, a native species with ornamental potential
Abstract Angelonia integerrima Sprengel is a native species of the state of Mato Grosso do Sul and the Southern region (Paraná, Santa Catarina and Rio Grande do Sul) of Brazil, with features such as an unusual appearance and color of the flowers, indicating an ornamental use. To optimize the use of this species and to fill in gaps regarding its cytogenetic

2. Relationships between land use and water quality obtained for the evaluation of genotoxic effects in plant bioindicators
Resumo As atividades antrópicas bem como o uso e ocupação da terra estão intimamente ligadas à qualidade da água e do solo. Uma alternativa para avaliar suas influências na qualidade da água em corpos hídricos é através do biomonitoramento utilizando Allium cepa como organismo bioindicador. Esta técnica permite detectar anormalidades citogenétic

3. Phenotypic, cytogenetic and spike fertility characterization of a population of male-sterile triticale
Triticale (X Triticosecale Wittmack) is a good cereal for production of flour and feed. A segregating population of triticale was developed from a male-sterile (MS) plant. To determine whether this new source of male sterility in triticale is appropriate for use in breeding programs the expression of the male sterility phenotype was characterized through spi

4. Mining plant genome browsers as a means for efficient connection of physical, genetic and cytogenetic mapping: an example using soybean
Physical maps are important tools to uncover general chromosome structure as well as to compare different plant lineages and species, helping to elucidate genome structure, evolution and possibilities regarding synteny and colinearity. The increasing production of sequence data has opened an opportunity to link information from mapping studies to the underly

6. Cytogenetic data for Paspalum notatum Flügge accessions / Dados citogenéticos para acessos de Paspalum notatum Flügge
Muitas espécies do genus Paspalum L. são importantes forragens, devido à qualidade, produtividade e tolerância para o stress ambiental. Números cromossômicos, configurações meióticas e fertilidade do pólen foram analisados em uma coleção de 85 acessos de Paspalum notatum Flügge e sete acessos de Pensacola (P. notatum var saurae). Todos os acesso

7. Caracterização cromossomica em cana-de-açucar (Saccharum spp., Poaceae) / Sugarcane chromosomal characterization (Saccharum spp., Poaceae)
A cana-de-açúcar assumiu grande importância no cenário econômico mundial, não só pela produção de açúcar, mas também de etanol. Variedades modernas de cana-de-açúcar são essencialmente derivadas de hibridações feitas no início do século XX entre duas spécies de Saccharum, S. officinarum (2n = 80) e S. spontaneum (2n = 40-128), seguidas de

8. Avaliação in silico do transcriptoma do café : identificação de SNPs e inferência de mecanismos de regulação da expressão gênica / In silico analysis of the coffee transcriptome : identification of SNPs and inference of mechanisms of gene expression regulation
Coffee is one of the most important crops in the world, being worldwide consumed and having significant participation in under development economies. Coffea arabica and Coffea canephora are responsible for 70% and 30% of commercial production, respectively. Cytogenetic analysis established that C. arabica is an autogamous alotetraploid formed by a recent (1

9. Estudos evolutivos em Myrtaceae : aspectos citotaxonomicos e filogeneticos em Myrteae, enfatizando Psidium e generos relacionados
Myrtaceae is one of the most diverse families in Neotropical region; principally belong to Mata Atlântica and Cerrado, reaching 10 to 15% of biodiversity of these biomes. Myrteae is the most generically tribe (73 genera and 2375 species) in this family. Generally, South-American taxa are considered a complex group and biosystematic studies are necessary to

11. Efficacy of HUMN criteria for scoring the micronucleus assay in human lymphocytes exposed to a low concentration of p,p'-DDT
The cytokinesis-block micronucleus (CBMN) assay is one of the standard cytogenetic tools employed to assess chromosomal damage subsequent to exposure to genotoxic/cytotoxic agents, and is widely applicable to plant, animal and human cells. In the present study, the CBMN assay was used to assess the baseline damage in binuclear human peripheral blood lymphocy

12. Utilização de técnicas citogenéticas, de citometria de fluxo e de imagem para caracterização do genoma de Coffea canephora e C. arabica / Utilization of cytogenetic, flow and image cytometric techniques for genome characterization of Coffea canephora and C. arabica
The application of cytogenetic, flow and image cytometric techniques has been enabling the genome characterization of Coffea arabica L. and Coffea canephora Pierre ex Froehner. These approaches have been providing relevant information for evolutionary studies and breeding programs. Considering the need of increasing the information available on the genomes o
