1. Molecular assessment of Gymnotus spp. (Gymnotiformes: Gymnotidae) fishing used as live baitfish in the Tietê River, Brazil
RESUMO A captura de iscas-vivas para a pesca esportiva constitui uma atividade importante em comunidades de pescadores. As principais espécies utilizadas para este propósito pertencem ao gênero Gymnotus, o qual compreende inúmeras espécies de natureza críptica que dificulta a identificação baseada na morfologia externa. Os objetivos deste trabalho fo

2. Morphological affinities of Homo naledi with other Plio-Pleistocene hominins: a phenetic approach
ABSTRACT Recent fossil material found in Dinaledi Chamber, South Africa, was initially described as a new species of genus Homo, namely Homo naledi. The original study of this new material has pointed to a close proximity with Homo erectus. More recent investigations have, to some extent, confirmed this assignment. Here we present a phenetic analysis based o

3. Cuticular n-alkane in leaves of seven Neotropical species of the family Lecythidaceae: a contribution to chemotaxonomy
ABSTRACT Biosynthesized from very long-chain fatty acid wax precursors, n-alkanes make a valuable contribution to the taxonomy of plants. The alkane components of foliar epicuticles of seven Neotropical species of Lecythidaceae were investigated: Bertholletia excelsa, Cariniana legalis, Couroupita guianensis, Eschweilera alvimii, Eschweilera ovata, Gustavia

4. Functional characterization of sugarcane mustang domesticated transposases and comparative diversity in sugarcane, rice, maize and sorghum
Transposable elements (TEs) account for a large portion of plant genomes, particularly in grasses, in which they correspond to 50%-80% of the genomic content. TEs have recently been shown to be a source of new genes and new regulatory networks. The most striking contribution of TEs is referred as “molecular domestication”, by which the element coding seq

5. Comparative karyotypic analysis in the Alstroemeria hookeri Lodd. (Alstroemeriaceae) complex sensu Bayer (1987)
Alstroemeria L. (Alstroemeriaceae) is an American genus of monocots with two principal distribution centers in Chile and Brazil. In Chile, it is represented by about 32 species, most of them in central Chile, an area known for its high level of endemism. The "complex" Alstroemeria hookeri is endemic to Chile, where it is distributed from the Coquimbo to the

6. Simultaneous infection of human host with genetically distinct isolates of Paracoccidioides brasiliensis
This study is the first report on genetic differences between isolates of Paracoccidioides brasiliensis from a single patient. We describe a simultaneous infection with genetically distinct isolates of P. brasiliensis in a patient with chronic paracoccidioidomycosis. The clinical isolates were obtained from lesions in different anatomical sites and were char

7. The enigmatic monotypic crab plover Dromas ardeola is closely related to pratincoles and coursers (Aves, Charadriiformes, Glareolidae)
The phylogenetic placement of the monotypic crab plover Dromas ardeola (Aves, Charadriiformes) remains controversial. Phylogenetic analysis of anatomical and behavioral traits using phenetic and cladistic methods of tree inference have resulted in conflicting tree topologies, suggesting a close association of Dromas to members of different suborders and line

8. Phenetic analysis of Panstrongylus megistus Burmeister, 1835 (Hemiptera: Reduviidae: Triatominae) in the State of Paraná-Brazil
Panstrongylus megistus é um importante vetor da Doença de Chagas e é apontado como uma das espécies com potencial para substituir Triatoma infestans como principal vetor desta doença no Brasil. Os diferentes graus de domiciliação por P. megistus - no Brasil - e sua importância epidemiológica evocam a necessidade de estudos com bases genéticas que p

9. Cariótipo molecular: uma ferramenta para o estudo analítico e evolutivo do genoma de Trypanosoma cruzi / Molecular karyotype: a tool for the analytical and evolutionary study of Trypanosoma cruzi genome.
Different typing methods and phylogenetic inference based on the nucleotide sequence of few nuclear genes indicate that Trypanosoma cruzi can be divided into two major groups named as T. cruzi I and T. cruzi II. Additional subgroups of isolates have been described, such as group of rDNA 1/2 and zymodeme 3 (Z3), whose phylogenetic relationships with the T. cr

10. Arbuscular mycorrhizal community in a permanent pasture and development of species-specific primers for detection and quantification of two AM fungi
Arbuscular mycorrhizal (AM) fungi are a group of symbionts that occupy different niches during their life cycle in roots and in the rhizosphere. They occur in soil as spores, hyphae and other propagules such as colonised root fragments. During the interaction with the plant roots a bidirectional transfer of mineral nutrients and carbon occurs, frequently ens

11. RESISTÊNCIA GENÉTICA DO FEIJÃO (Phaseolus vulgaris L.) AO Colletotrichum lindemuthianum / GENETIC RESISTANCE OF BEANS (Phaseolus vulgaris L.) TO Colletotrichum lindemuthianum
One hundred and twenty eight genotypes of common bean (Phaseolus vulgaris L.) divided into local varieties, cultivars and lines both from meso-america and andean gene pool, were evaluated in 2003 and 2004. Several experiments were conducted at Universidade Federal de Santa Maria, State of Rio Grande do Sul, Brazil. Host genetic structure was studied based on

12. Análise genômica e sequenciamento automático de rDNA em populações de fusarium oxysporum
Fusarium oxysporum complex causes wilt disease in a wide variety of plants and are grouped into formae speciales based on their host range. Twenty-one isolates of the complex which represented F. oxysporum, f. sp. cubense, f. sp. lycopersici, f. sp. passiflorae, and f. sp. capsici were assessed for genetic diversity using RFLPs of the IGS region, RAPD-PCR, a
