1. AFLP marker analysis revealing genetic structure of the tree Parapiptadenia rigida (Benth.) Brenan (Leguminosae-Mimosoideae) in the southern Brazilian Tropical Rainforest
Parapiptadenia rigida is a tropical early secondary succession tree characteristic of the Tropical Atlantic Rainforest. This species is of great ecological importance in the recovery of degraded areas. In this study we investigated the variability and population genetic structure of eight populations of P. rigida. Five AFLP primer combinations were used in a

2. Extended genetic analysis of Brazilian isolates of Bacillus cereus and Bacillus thuringiensis
Multiple locus sequence typing (MLST) was undertaken to extend the genetic characterization of 29 isolates of Bacillus cereus and Bacillus thuringiensis previously characterized in terms of presence/absence of sequences encoding virulence factors and via variable number tandem repeat (VNTR). Additional analysis involved polymerase chain reaction for the pres

3. Endogamy and genetic variability in selective mating using distribution of extremes
The objective of this study was to evaluate selective mating using distribution of extremes, among other mating strategies, on its ability to decrease the endogamy and the loss of genetic variability. The genetic simulation system (Genesys) was used to simulate two genomes (each one with a single characteristic whose distinction was the value of heritability

4. Genetic approaches for studying transgene inheritance and genetic recombination in three successive generations of transformed tobacco
Transgene integration into plant genomes is a complex process accompanied by molecular rearrangements. Classic methods that are normally used to study transgenic population genetics are generally inadequate for assessing such integration. Two major characteristics of transgenic populations are that a transgenic genome may harbor many copies of the transgene

6. Tuning of multivariable decentralized controllers through the ultimate-point method
A successful method for tuning single-loop PID controllers is the ultimate-point method. This method is based on the identification of the ultimate point of the process’ frequency response followed by its shifting, through appropriate choices of the controller’s parameters, to a specified location of the complex plane. This paper presents an extension of

7. Genome re-assignment of Arachis trinitensis (Sect. Arachis, Leguminosae) and its implications for the genetic origin of cultivated peanut
The karyotype structure of Arachis trinitensis was studied by conventional Feulgen staining, CMA/DAPI banding and rDNA loci detection by fluorescence in situ hybridization (FISH) in order to establish its genome status and test the hypothesis that this species is a genome donor of cultivated peanut. Conventional staining revealed that the karyotype lacked th

8. Análise de expressão e splicing alternativo do gene Mdh-1 de Apis mellifera L. (Hymenoptera: Apidae)
Mdh-1 enzyme locus coding for cytoplasmic malate dehydrogenase has three common alleles Mdh-1100 (F), Mdh-180 (M) e Mdh-165 (S) and it has been extensively used as racial marker in populational studies of Apis mellifera. Additional isoforms are detected by electrophoretic analysis during ontogenetic development of A. mellifera, indicating differential expres

9. THE FORMATION TRAJECTORIES AND THE UNIVERSE OF WORK OF ENVIRONMENTAL EDUCATORS: A DIALOG WITH THE MEMORIAL TEXTS / A FORMAÇÃO E O TRABALHO DOS EDUCADORES AMBIENTAIS: UM DIÁLOGO COM AS MEMÓRIAS
This piece of research endeavors to shed light on the formation trajectories and the universe of work of a professional category identified as environmental educators. To that purpose, an introductory discussion brings up present problems in the realm of Environmental Education (EE), its institutionalization, and the professionalization of its agents against

10. Avaliação da funcionalidade do locus acessory gene regulator (agr) em cepas de «Staphylococcus aureus» brasileiras com suscetibilidade reduzida aos glicopeptídeos / Characterisation of the accessory gene regulator in Brazilian Staphylococcus aureus strains with reduced susceptibility to vancomycin.
The treatment of staphylococcal infections has lately been a strenuous undertaking due to the resistance of Staphylococcus aureus to multiple antibiotics. The antimicrobial drug of choice for the treatment of methicillin resistant S. aureus (MRSA) is the glycopeptide vancomycin. Since the first isolation of S. aureus with reduced susceptibility to vancomycin

11. Analysis of the genetic diversity using molecular markers is characteristic cytomorfological in Colletotrichum gloeosporioides / AnÃlise da diversidade genÃtica atravÃs de marcadores moleculares e caracterÃsticas citomorfolÃgicas de Colletotrichum gloeosporioides
Foram analisadas 20 linhagens de C. gloeosporioides quanto Ãs caracterÃsticas genÃticas e citomorfolÃgicas. Os marcadores moleculares, RAPD, microssatÃlites, Intron Spice Site Primer e regiÃo ITS do DNA ribossomal, foram utilizados para avaliar a diversidade genÃtica entre as linhagens. A anÃlise de agrupamento atravÃs do mÃtodo UPGMA confirmou a d

12. GENUS THREE CURVES IN CHARACTERISTIC TWO / CURVAS DE GENÊRO TRÊS EM CARACTERÍSTICA DOIS
We study the variety M3 of curves of genus three in characteristic two. For each of the curves we compute the possible number of Weierstrass points, their weights, normalizations of many loci in the moduli space, and so on. We also deal with the concept of a Galois point.
