13. Mapeamento de genes de lipoxigenases para uso na seleção assistida de soja; : Análise da expressão da glicosiltransferase implicadas na síntese de precursores de aromas de tomate por PCR quantitativa / Análise da expressão da glicosiltransferase implicadas na síntese de precursores de aromas de tomate por PCR quantitativa
Soybean (Glycine max (L. ) Merrill has been considered the main available source of vegetable protein and its culture has a worldwide relevance. Brazil is the second biggest producer and wordwide exporter. The high socioeconomic importace of soybean is mainly attributed to its much favorable combination of high protein and oil contents together with appropri

14. Diversidade genética de etnovariedade de mandioca (Manihot esculenta Crantz) em áreas de Cerrado no Estado do Mato Grosso do Sul e de variedades comerciais por meio de marcadores microssatélites / Genetic diversity of cassava (Manihot esculenta Crantz) landraces in Cerrado areas in Mato Grosso do Sul State and commercial varieties with microsatellites markers
Studies with cassava (Manihot esculenta Crantz) landraces, originated from different regions in Brazil, using microsatellite markers, allows the estimation of genetic diversity and the distribution of this diversity within and among households, geographic communities and regions. The objective of this study was to characterize the genetic diversity of 83 cas

15. Regulação da biossíntese de ácidos graxos insaturados durante a ontogenia de sementes de soja / Regulation of the unsaturated fatty acid biosynthesis during the ontogeny of soybean seeds
The fatty acid composition of soybean seeds has a direct impact on its oxidative stability. High levels of polyunsaturated fatty acids such as linoleic and linolenic acids make the oil more susceptible to hydrolytic and oxidative degradation leading to the formation of volatile compounds which alter the quality and flavor of foods. For this reason, there is

16. Variability among Phaeoisariopsis griseola isolates / Variabilidade entre isolados de Phaeoisariopsis griseola
Common bean (Phaseolus vulgaris L.) angular leaf spot, caused by the fungus Phaeoisariopsis griseola (Sacc.) Ferraris, is responsible for extensive yield losses of common bean in Brazil. Yield loss can reach up to 80% under disease favorable environmental conditions. Breeding for disease resistance is the most effective strategy to control the bean angular l

17. Genetic mapping by molecular markers with gametic and genotypic segregation distortion / Mapeamento genético utilizando marcadores moleculares com distorção de segregação gamética e genotípica
The development of the genetic maps based on DNA markers has been providing remarkable progresses to the genomics of plants and animals. The construction of a genetic map is performed, by using data from the segregant populations, that usually are backcrossing, F2 generation, RILs, double-haploids and others. A mendelian segregation pattern that is typical t

18. Mapeamento de QTLs para reação à doença mancha de Phaeosphaeria em milho. / Mapping QTLs for reaction to Phaeosphaeria leaf spot disease in maize.
Phaeosphaeria leaf spot disease in maize (Zea mays L.) has becoming a concern in Brazil in the last years because of its increase spreading in maize growing areas. Inheritance studies of the reaction of maize genotypes to this foliar disease are necessary to support plant breeding programs. Thus, the objective of this research was to map QTLs to study the in

19. Mapping of QTLs for common bean traits using microsatelites markers / Mapeamento de QTLs para caracteres do feijoeiro por meio de microssatÃlites
The identification of QTLs is the initial step in the application of the selection assisted by molecular markers in breeding programs. The common bean counts on molecular map with good saturation, QTLs identified and SSR markers. However until the moment, there is few QTLs linked to SSR markers, therefore the identification of these markers for the common be

20. Evaluation of the Genetic Structure of Xylella fastidiosa Populations from Different Citrus sinensis Varieties
Xylella fastidiosa was isolated from sweet orange plants (Citrus sinensis) grown in two orchards in the northwest region of the Brazilian state of São Paulo. One orchard was part of a germ plasm field plot used for studies of citrus variegated chlorosis resistance, while the other was an orchard of C. sinensis cv. Pêra clones. These two collections of stra
