26. Genetic diversity in soybean germplasm identified by SSR and EST-SSR markers.
Abstract ? The objectives of this work were to investigate the genetic variation in 79 soybean (Glycine max) accessions from different regions of the world, to cluster the accessions based on their similarity, and to test the correlation between the two types of markers used. Simple sequence repeat markers present in genomic (SSR) and in expressed regions (E

27. Evaluation of the number and information content of fluorescent-labeled SSR markers for rice germplasm characterization.
The use of fluorescent-labelled simple sequence repeat (SSR) markers allows the simultaneous analysis of diverse loci in multiplex series, providing an enhanced precision of the determination of the allele size when a large number of genotypes is used. Twenty-five fluorescent-labelled SSR markers were used to genotype 242 accessions of the Brazilian Rice Cor

28. Desenvolvimento de marcadores SSR, M-AFLP e SNP visando à integração de mapas genético-moleculares de Passiflora alata Curtis / Development of SSR, M-AFLP and SNP markers for linkage map integration of Passiflora alata Curtis
Embora não exista uma variedade comercial de maracujazeiro-doce (Passiflora alata Curtis), a fruta vem ganhando espaço no mercado brasileiro, justificando o uso de técnicas convencionais e moleculares no melhoramento da cultura. Nas espécies em que ocorre autoincompatibilidade e o cruzamento entre indivíduos é obrigatório, como nos maracujazeiros, nã

29. Genetic diversity in cultivated carioca common beans based on molecular marker analysis
A wide array of molecular markers has been used to investigate the genetic diversity among common bean species. However, the best combination of markers for studying such diversity among common bean cultivars has yet to be determined. Few reports have examined the genetic diversity of the carioca bean, commercially one of the most important common beans in B

30. Mapeamento genético de cana-de-açúcar (Saccharum spp.) por associação empregando marcadores SSR e AFLP / Genetic mapping of sugar cane (Saccharum spp.) by association using SSR and AFLP markers
A cultura da cana-de-açúcar (Saccharum spp.) possui uma importância histórica e econômica para o Brasil. O agronegócio sucroalcooleiro vem experimentando forte expansão na última década não só no Brasil como também em todo o mundo em função, principalmente, da demanda por fontes de energia menos agressivas ao ambiente. Para atender a uma maior

31. Expression analyses of candidate resistance genes in the Rpp4 Asian Soybean Rust resistance locus.
Asian Soybean Rust (ASR), caused Phakopsora pachyrhizi, is considered the most severe soybean disease around the world. Infection of susceptible genotypes leads to early defoliation, incomplete seed development, and yield losses as high as 80%. Five ASR resistance genes have been identified in soybean: Rpp1, Rpp2, Rpp3, Rpp4 and Rpp5. Of particular interest

32. Association mapping for yield and grain quality traits in rice (Oryza sativa L.)
Association analysis was applied to a panel of accessions of Embrapa Rice Core Collection (ERiCC) with 86 SSR and field data from two experiments. A clear subdivision between lowland and upland accessions was apparent, thereby indicating the presence of population structure. Thirty-two accessions with admixed ancestry were identified through structure analys

33. Development of microsatellite markers for identifying Brazilian Coffea arabica varieties
Microsatellite markers, also known as SSRs (Simple Sequence Repeats), have proved to be excellent tools for identifying variety and determining genetic relationships. A set of 127 SSR markers was used to analyze genetic similarity in twenty five Coffea arabica varieties. These were composed of nineteen commercially important Brazilians and six interspecific

34. SSR and AFLP based genetic diversity of soybean germplasm differing in photoperiod sensitivity
Forty-four soybean genotypes with different photoperiod response were selected after screening of 1000 soybean accessions under artificial condition and were profiled using 40 SSR and 5 AFLP primer pairs. The average polymorphism information content (PIC) for SSR and AFLP marker systems was 0.507 and 0.120, respectively. Clustering of genotypes was done usin

35. Mapeamento genético de híbridos intraespecíficos de laranja doce [Citrus sinensis (L.) Osbeck], obtidos por cruzamentos controlados / Genetic mapping of intraspecific hybrids of sweet orange [Citrus sinensis (L.) Osbeck], obtained by controlled breeding
Apesar do destaque do setor citrícola paulista e brasileiro, existe uma séria vulnerabilidade para o cultivo da laranja, que está pautada no uso de poucas variedades comerciais. A instalação de programas de melhoramento de laranjeiras com uso de cruzamentos controlados é dificultada principalmente pelos problemas de poliembrionia nas sementes e pela pr

36. Genetic variability in Brazilian wheat cultivars assessed by microsatellite markers
Wheat (Triticum aestivum) is one of the most important food staples in the south of Brazil. Understanding genetic variability among the assortment of Brazilian wheat is important for breeding. The aim of this work was to molecularly characterize the thirty-six wheat cultivars recommended for various regions of Brazil, and to assess mutual genetic distances,
