1. [PROVISIONAL] Low cytomolecular diversification in the genus Stylosanthes Sw. (Papilionoideae, Leguminosae)
Abstract Stylosanthes (Papilionoideae, Leguminosae) is a predominantly neotropical genus with ~ 48 species that includes worldwide important forage species. This study presents the chromosome number and morphology of eight species of the genus Stylosanthes (S. acuminata, S. gracilis, S. grandifolia, S. guianensis, S. hippocampoides, S. pilosa, S. macrocephal

2. The importance of integrons for development and propagation of resistance in Shigella: the case of Latin America
Abstract In Latin America, the disease burden of shigellosis is found to coexist with the rapid and rampant spread of resistance to commonly used antibiotics. The molecular basis of antibiotic resistance lies within genetic elements such as plasmids, transposons, integrons, genomic islands, etc., which are found in the bacterial genome. Integrons are known t

3. Seleção genômica ampla e novos métodos de melhoramento do milho / Genome wide selection and new methods of maize breeding
The evaluation for nutrient efficiency use (UE) generally use destructive methods of the plant, not allowing, depending on the population genetic structure, using those identified as superior in hybridizations. Consequently, there is a reduction in the potential gains with selection. Additionally, some conventional breeding methods, such as the recurrent sel

4. Genomic imbalances in esophageal squamous cell carcinoma identified by molecular cytogenetic techniques
This review summarizes the chromosomal changes detected by molecular cytogenetic approaches in esophageal squamous cell carcinoma (ESCC), the ninth most common malignancy in the world. Whole genome analyses of ESCC cell lines and tumors indicated that the most frequent genomic gains occurred at 1, 2q, 3q, 5p, 6p, 7, 8q, 9q, 11q, 12p, 14q, 15q, 16, 17, 18p, 1

5. Genetic control of common bean resistance to white mold and backcross assisted by microsatellite markers / GENÃTICA DA RESISTÃNCIA DO FEIJOEIRO AO MOFO BRANCO E USO DO RETROCRUZAMENTO ASSISTIDO POR MARCADORES MICROSSATÃLITES.
The identification of sources of resistance to the white mold in common bean, and the study of its inheritance is primordial for the success of breeding programs aiming at resistant cultivars. The present research had the objectives: 1) to study the nature and the magnitude of genetic effects of resistance to white mold 2) use microsatellite (SSR) markers to

6. Citogenética evolutiva en Leguminosas americanas
ABSTRACT Chromosomic features described so far for Americans legumes are reviewed and analyzed, simultaneously with morphological and molecular characters. This is an invaluable opportunity to propose hypotheses about chromosome changes during the family divergence and speciation processes. The chromosome studies showed wide inter-generic, inter and intra-sp

7. Retrocruzamentos visando à obtenção de resistência do maracujazeiro-azedo à virose do endurecimento dos frutos, auxiliados por marcadores moleculares / Backcrossing aiming the resistance of sour passion fruit to woodiness passion fruit virusis resistance assisted by molecular markers
Brazil is an expoent in passion fruit production, however, the average productivity is quite below its potential. Among the reasons for low productivity are the phytosanitary problems, that compromise the production and the quality of the fruit. Breeding programs that use intra and interspecific crossings have been conducted to overcome these problems. The o

8. VariaÃÃes transcricionais dos genes AR, SRD5A2, KLK2, PCA3, KLK3 e PSMA e implicaÃÃes no diagnÃstico molecular do cÃncer de prÃstata
CHAPTER I - Prostate cancer is a common disease in the world and in some countries it is one of the main causes of male population mortality. Some molecular markers have been associated with prostate carcinogenesis. To observe changes in transcript levels of the AR, SRD5A2, KLK2, PSMA and PCA3 genes, the mRNA was analyzed in tissues with prostatic adenocarci

9. Microsatellite-assisted backcross selection in maize
A microsatellite marker (SSR) was chosen to simulate a target allele and three criteria (02, 04 and 06 markers per chromosome) were tested to evaluate the most efficient parameters for performing marker-assisted backcross (MAB) selection. We used 53 polymorphic SSRs to genotype 186 BC1 maize (Zea mays L.) plants produced by crossing the inbred maize lines L-

10. Conversion of elite inbred lines into Quality Protein Maize (QPM). 2003. / ConversÃo de linhagens elites em milho de alta qualidade protÃica (QPM).
The current study was developed to evaluate the potential of the modified backcross procedure proposed by GuimarÃes et al. (2000), and the molecular markers to increase the efficiency in conversion projects of elite inbred lines into Quality Protein Maize. First, it was evaluated the association of the SSR markers umc1066, phi057 and phi112 with the opaque-

12. Genome-Wide High-Resolution Mapping by Recurrent Intermating Using Arabidopsis Thaliana as a Model
We demonstrate a method for developing populations suitable for genome-wide high-resolution genetic linkage mapping, by recurrent intermating among F(2) individuals derived from crosses between homozygous parents. Comparison of intermated progenies to F(2) and ``recombinant inbred'' (RI) populations from the same pedigree corroborate theoretical expectations
