1. Grain productivity and soybean answer standard to the environmental variations at Minas Gerais state / Produtividade de grãos e padrão de resposta da soja às variações ambientais no estado de Minas Gerais
This work was aimed of following objectives: made a report of Centroid method and suggest new ideotypes for analyze, to evaluate the productivity and to determine the adaptability and stability of grains productivity of lineages and cultivars of soybean of the different maturation cycles, for the Centroid and Annicchiarico methods, identifying the genotypes

2. Mapping of functional RFLP derived markers in sugarcane (Saccharum sp.) / Mapeamento funcional em cana-de-açucar utilizando ESTs como marcadores moleculares
Sugarcane (Saccharum spp.) is the species that has the greatest economic importance in the world, as it is one of the main sources of sugar and alcohol production. Although Brazil is the biggest producer of this crop - participating with 25% of world production, the productivity levels are considered low. The acquisition of new sugarcane varieties, which are

3. Determinação da pureza varietal em lotes de sementes de milho através de marcadores morfológicos e microssatélites. / Determination of varietal purity in maize seed lots using morphological and microsatellites markers.
Maize inbred lines seed production has been conducted to avoid the presence of varietal contamination since it compromises the subsequent multiplication phases within the commercial seed program. Contaminant seeds are detected through varietal and/or genetic purity determination tests which are usually based on morphological and biochemical markers, dependin

4. Natural selection and the breederâs decision about the best moment to extract families in common bean. / SeleÃÃo natural e a decisÃo do melhorista sobre o melhor momento de abrir o Bulk na cultura do feijoeiro
The âbulkâ method presents some advantages, including the versatility in extracting families at any moment. Theoretically there is no justification in delaying line extraction beyond the F5 generation, but if there is action of natural selection in the direction required by the breeders, a question of whether delaying line extraction would increase the cha

5. Localization of RNAs to the Mitochondrial Cloud in Xenopus Oocytes through Entrapment and Association with Endoplasmic ReticulumV⃞
The germ cell lineage in Xenopus is specified by the inheritance of germ plasm, which originates within a distinct “mitochondrial cloud” (MC) in previtellogenic oocytes. Germ plasm contains localized RNAs implicated in germ cell development, including Xcat2 and Xdazl. To understand the mechanism of the early pathway through which RNAs localize to the MC,

6. Neural Induction in Xenopus: Requirement for Ectodermal and Endomesodermal Signals via Chordin, Noggin, β-Catenin, and Cerberus
The origin of the signals that induce the differentiation of the central nervous system (CNS) is a long-standing question in vertebrate embryology. Here we show that Xenopus neural induction starts earlier than previously thought, at the blastula stage, and requires the combined activity of two distinct signaling centers. One is the well-known Nieuwkoop cent
