25. Aperfeiçoamento da fermentação de sacarose através da modificação da expressão dos genes SUC2 e AGT1 em linhagens diploides de Saccharomyces cerevisiae. / Improvement of sucrose fermentation by modifying the expression of SUC2 and AGT1 genes in diploid Saccharomyces cerevisiae strains.
Currently, the S. cerevisiae strains used in industrial production of fuel alcohol in Brazil are diploid yeasts that of metabolize sucrose through its extracellular hydrolysis by the periplasmic invertase, followed by the transport of the formed glucose and fructose into the cells, and further metabolism through glycolysis. In this study, utilizing genetic e

27. Multidisciplinary Design Optimization of Sounding Rocket Fins Shape Using a Tool Called MDO-SONDA
Abstract: Multidisciplinary design optimization is a promising field in aerospace engineering. However, advances in this field have not been applied yet to improve Brazilian sounding rockets, such as the VS-40. Therefore, to give a perspective of the multidisciplinary design optimization in this context, this work presented a case study of this rocket, which

28. Development and characterization of hybrids from native wine yeasts
For commercial purposes, the winemaking industry is constantly searching for new yeast strains. Historically, this has been achieved by collecting wild strains and selecting the best for industrial use through an enological evaluation. Furthermore, the increasing consumer demands have forced the industry to incorporate new strategies such as genetic engineer

30. Bacillus thuringiensis monogenic strains: screening and interactions with insecticides used against rice pests
The screening of Bacillus thuringiensis (Bt) Cry proteins with high potential to control insect pests has been the goal of numerous research groups. In this study, we evaluated six monogenic Bt strains (Bt dendrolimus HD-37, Bt kurstaki HD-1, Bt kurstaki HD-73, Bt thuringiensis 4412, Bt kurstaki NRD-12 and Bt entomocidus 60.5, which codify the cry1Aa, cry1Ab

31. Genetic architecture of purple pigmentation and tagging of some loci to SSR markers in pearl millet, Pennisetum glaucum (L.) R. Br.
This report describes the construction of integrated genetic maps in pearl millet involving certain purple phenotype and simple sequence repeat (SSR) markers. These maps provide a direct means of implementing DNA marker-assisted selection and of facilitating "map-based cloning" for engineering novel traits. The purple pigmentation of leaf sheath, midrib and

32. Protection of genetic heritage in the era of cloning
Research on human beings has expanded greatly due to progress and the evolution of society as well as customs. Not only the unceasing development of research on human beings, but also interference in the beginning and end of life with homologous and heterogonous human reproduction, surrogate motherhood, cloning, gene therapies, eugenics,euthanasia, dysthanas

33. Desenvolvimento de estratégia para extrusão de lipídios por engenharia genética, subsequente à análise genética da via exocítica da microalga Neochloris oleoabundans / Development of genetic engineering atrategy of lipids extrusior following the genetic analysis of exocytic pathway from micralga Neochloris oleoabudans
Há no mundo um consenso sobre a necessidade de se encontrar fontes de carbono renováveis para a substituição do petróleo. O cultivo de microalgas tem sido considerado uma alternativa promissora para suprir essas cadeias carbônicas e biocombustíveis, visto que são microorganismos fotossintetizantes que podem acumular grandes quantidades de triacilglic

36. Caracterização de determinantes genéticos envolvidos na qualidade industrial e nutricional do fruto de tomate / Characterization of genetic determinants involved in industrial and nutritional quality of tomato fruit
This thesis addresses tomato fruit metabolism analysis by using three complementary approaches: i) the identification of candidate genes co-located with QTL previously described from metabolic profiles of S. lycopersicum (cv. M82) and S. pennellii introgressed lines, associated with industrial and nutritional quality traits; ii) the structural analyses of th
