13. Evaluation of SRAP markers for mapping of Pisum sativum L.
Abstract Linkage maps have become important tools for genetic studies. With the aim of evaluating the SRAP (sequence-related amplified polymorphism) technique for linkage mapping in Pisum sativum L., a F2 mapping population derived from an initial cross between cvs. DDR11 and Zav25 were generated. A total of 25 SRAP primer combinations were evaluated in 45 F

14. Genome selection in fruit breeding: application to table grapes
ABSTRACT Genomic selection (GS) has recently been proposed as a new selection strategy which represents an innovative paradigm in crop improvement, now widely adopted in animal breeding. Genomic selection relies on phenotyping and high-density genotyping of a sufficiently large and representative sample of the target breeding population, so that the majority

15. Molecular characterization of Mycobacterium tuberculosis isolates from Tehran, Iran by restriction fragment length polymorphism analysis and spoligotyping
Abstract: INTRODUCTION Characterization of Mycobacterium tuberculosis (MTB) isolates by DNA fingerprinting has contributed to tuberculosis (TB) control. The aim of this study was to determine the genetic diversity of MTB isolates from Tehran province in Iran. METHODS MTB isolates from 60 Iranian and 10 Afghan TB patients were fingerprinted by standard IS

16. Molecular characterisation of the NSP4 gene of group A human rotavirus G2P[4] strains circulating in São Paulo, Brazil, from 1994 and 2006 to 2010
Group A human rotaviruses (HuRVA) are causative agents of acute gastroenteritis. Six viral structural proteins (VPs) and six nonstructural proteins (NSPs) are produced in RV-infected cells. NSP4 is a diarrhoea-inducing viral enterotoxin and NSP4 gene analysis revealed at least 15 (E1-E15) genotypes. This study analysed the NSP4 genetic diversity of HuRVA G2P

17. Characterization of the complete mitochondrial genome and a set of polymorphic microsatellite markers through next-generation sequencing for the brown brocket deer Mazama gouazoubira
The complete mitochondrial genome of the brown brocket deer Mazama gouazoubira and a set of polymorphic microsatellite markers were identified by 454-pyrosequencing. De novo genome assembly recovered 98% of the mitochondrial genome with a mean coverage of 9-fold. The mitogenome consisted of 16,356 base pairs that included 13 protein-coding genes, two ribosom

18. Genetic divergence among maize hybrids by morphological descriptors
Two experiments with 25 maize commercial hybrids were carried out in a direct sowing system in Southern Brazil in the harvests of 2009/2010 and 2010/2011. Quantitative descriptors were used with the objective of determining the genetic divergence and the relative contributions of traits among hybrids for extraction of inbred lines. This study was carried out

19. Chromosomal localization of microsatellite loci in Drosophila mediopunctata
Drosophila mediopunctata has been used as a model organism for genetics and evolutionary studies in the last three decades. A linkage map with 48 microsatellite loci recently published for this species showed five syntenic groups, which had their homology determined to Drosophila melanogaster chromosomes. Then, by inference, each of the groups was associated

20. First characterization of a Providencia stuartii clinical isolate from a Tunisian intensive care unit coproducing VEB-1-a, OXA-2, qnrA6 and aac(6')-Ib-cr determinants
A clinical Providencia stuartii isolate SM662 was recovered from a patient hospitalized in the intensive care unit at the Military hospital, Tunisia. This isolate was resistant to penicillins, cephalosporins, aminoglycosides and fluoroquinolones. A marked in vitro synergy between ceftazidime or cefotaxime and amoxicillin-clavulanic acid on Mueller-Hinton aga

21. Desenvolvimento de um modelo para construção de mapas genéticos em autopoliploides, com aplicações em cana-de-açúcar / Development of a model to build genetic maps in autopolyploides, with applications in sugarcane
Autopolyploid species are extremely important in agriculture. However, the complex structure of their genomes is not well understood. Despite all advances in genetic mapping of autotetraploids, the vast majority of the models used for autopolyploid species with high ploidy level, such as sugarcane, are approximations of those used in diploid organisms. Thus,

22. Mapa genético-molecular para Hevea brasiliensis e mapeamento de QTL s para características de impotância econômica / Genetic linkage map for H. brasiliensis and QTL s mapping for important economic traits
A seringueira é uma espécie de cruzamento misto e com um longo ciclo de vida, o que dificulta a geração de linhagens endogâmicas e, por consequência, a construção e integração de mapas de ligação usando as metodologias convencionais. A exemplo do que tem sido feito em outras espécies vegetais que apresentam limitações para a obtenção de linh

23. Análise do desequilíbrio de ligação e da estrutura populacional do germoplasma brasileiro de cana-de-açúcar / Analysis of linkage disequilibrium and population structure from the sugarcane Brazilian germplasm
A cana-de-açúcar (Saccharum spp.) é uma cultura muito importante para a produção de açúcar e álcool no Brasil. Um importante avanço a respeito do seu genoma tem surgido com o emprego de marcadores moleculares, os quais têm sido extensamente utilizados para diversas finalidades, como o mapeamento de QTLs a partir de cruzamentos bi-parentais.

24. Método de Haseman-Elston e suas modificações no estudo de genes controladores de característica quantitativa / Haseman-Elston methodology and modifications on the study genes underlining quantitative trait loci
QTL mapping allows to study loci that play a role in complex traits, as well to determine their chromosomal locations. For this purpose, a set of methods useful for the study of quantitative traits are those based on Haseman-EIston regression, that is quite used in human genetics. These are robustness regression methods for linkage analysis that can be used
