13. Identification and characterization of genes differentially expressed during arbuscular mycorrhiza development in sugarcane / Identificação e caracterização de genes com expressão diferencial durante o desenvolvimento de micorrizas arbusculares em cana-de-açúcar
Arbuscular mycorrhizae (AM) are mutualistic symbiotic associations between fungi of the order Glomales and most of the terrestrial plants. The molecular mechanisms regulating AM development and efficiency are not well understood so that agricultural large scale application is so difficult. Although so many approaches are being used to the identification of d

14. ObtenÃÃo e CaracterizaÃÃo de calos e plÃntulas a partir de embriÃes zigÃticos imaturos de Coffea arabica L. e anÃlise in silico do Gene Serk / Obtaining and characterization of calluses and plantules starting from immature zygotic embryos of Coffea arabica L. and gene SERK in silico analysis
It was intended in this work be obtained alternatives to the explant to foliate and nodal seeking the micropropagation of you cultivate of coffee plants related to the quality of the drink, like âBourbon Amareloâ and to the productivity as the âRubiâ for the south area of Minas Gerais. A main plant of Bourbon Amarelo was used for obtaining of the fruits

15. Seleção de cafeeiros arábicos resistentes à mancha aureolada (Pseudomonas Syringae pv. Garcea)
A cafeicultura brasileira tem sofrido severos danos pela doença mancha aureolada causada pela bactéria Pseudomonas syringae pv. garcae, principalmente em regiões cafeeiras mais frias e expostas a ventos. É possível o controle químico desta doença, porém, em lavouras adultas, na maioria das vezes, o controle é antieconômico. O objetivo deste trabalh

16. Expressão recombinante da canacistatina em células de inseto.
Due to the great economic importance of sugarcane crop in Brazil, the occurrence of infections by phytopathogens leading to decreased productivity and quality remains a serious problem. As the plants have natural mechanisms of defense against the attack of fungi and insects, amongst which the inhibitors of proteases are distinguished, the use of these substa

17. Avaliação da citotoxicidade, genotoxicidade e dos efeitos protetores do extrato de Anacardium occidentale L. in vitro
The use of vegetable species in order to treat and cure diseases leads us back to the beginning of our civilization, to the moment in which man started a long journey of handling, adaptation and modification of these natural resources for his own benefit. Among the plants that continue to be a great source of medicine to the humanity is the Anacardium occide

18. Caracterização fenotípica e tentativa de obtenção de fase sexuada em Colletotrichum sublineolum
A antracnose do sorgo (Sorghum bicolor L.), causada pelo patógeno Colletotrichum sublineolum P. Henn, é uma das mais importantes doenças que afetam a cultura no Brasil, estando presente em todas as regiões de plantio. O presente trabalho teve como objetivos: (I) caracterizar linhagens selvagens e mutantes para o gene da nitrato redutase em relação à m

19. Diversidade genética em populações de Aechmea fulgens Brongn. (Bromeliaceae) em fragmentos de Mata Atlântica em Pernambuco.
Habitats fragmentation is the greatest cause of biodiversity erosion in tropical forests among the anthropic action. Due to the high degree of fragmentation and the isolation of the remaining Atlantic forest, many populations are being extinguished locally while others are suffering losses of its genetic variability. The Bromeliaceae family has a great varie

20. 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

21. Avaliação in vitro do potencial mutagênico de bidens pilosa Liné (picão - preto) e de Mikania glomerata Sprengel (guaco), por meio de ensaio do cometa e teste de micronúcleo
O consumo de Bidens pilosa Line (picao-preto) e de Mikania glomerata Sprengel (guaco) na forma de chas ocorre com freqüência na sociedade, principalmente em casos de ictericia e de afeccoes de vias aereas superiores, respectivamente. Para verificar a possível capacidade destas duas plantas de induzir danos ao DNA, foram utilizados o ensaio do cometa (SCGE

22. FMNL1 : caracterização de um novo gene humano relacionado com a familia das forminas
Formins are proteins that are involved in processes such as morphogenesis, embryonic differentiation, cytokinesis, cell polarity and survival. The formins are multidomain proteins that are conserved from plants to fungi and vertebrates. A search of the ORESTES database, generated from the Human Cancer Genome Project, identified 2 ESTs that were similar to th

24. Mechanisms of sugarcane response to herbivory
Deciphering plant-insect interactions at the molecular level is one of the major topics of interest in contemporary plant biology research. In the last few years, various aspects of the plant response to insect damage have been investigated, including the characterization of direct and indirect responses, the regulation of gene expression resulting from inse
