1. Comparison of in vitro callus-cultures from transgenic maize AG-5011YG (MON810) and conventional near-isogenic maize AG-5011
Abstract MON810 is a genetically-modified (GM) maize (Zea mays) event commonly employed in insect-resistant GM maize hybrids. GM events obtained by biolistic transformation methods, such as MON810, are generated by insertion of a recombinant gene expression cassette in a random locus of the plant genome, and this process may cause emergent properties besides

2. Transformação de plantas.
ABSTRACT: During centuries mankind plants to obtain cultivars with superior characteristics. However, conventional methods of plant breeding present limitations. The development of transformation methods created possibilities of great progresses in plant breeding because it offers the opportunity to introduce exogenous genes into superior cultivars to obtain

3. Caracterização bioquímica e molecular da ß-Galactosidade durante a maturação de frutos de coffea arabica
ß-galactosidases are a class of glycosyl-hydrolases that act on the plant cell primary walls, hydrolyzing ß-D-galactose at the nonreducing ends of ß-D-galactosides present in several biological molecules. Initially a characterization of the monosaccharides present in the primary wall of the pericarp and endosperm of Coffea arabica fruits at different ripe

4. Análise da via de regulação gênica do miRNA156/SPL na brotação lateral e caracterização molecular do processo de emergência da gema axilar de cana de açucar / Analysis of the role(s) of the miRNA156/SPL pathway on branching/tillering and molecular characterization of sugarcane lateral bud outgrowth
Sugarcane is an economically important biofuel crop that recently has become a target for improvement of sustainable biomaterial production due to its high biomass productivity and built-in containment features. Therefore, studies aiming to improve the production of biomass per area are among the most important issues in sugarcane production. Plant biomass i

5. Acúmulo de ricina em sementes de mamona e silenciamento do gene em plantas geneticamente modificadas
Castor bean (Ricinus communis L.) is an oilseed of great economic and social importance. The oil extracted from its seeds is used in biodiesel production and as raw material for chemicals, cosmetics and lubricants. Besides the oil extracted from the seeds, their production chain generates side-products, which can be used as organic fertilizer of good quality

6. Genetic Transformation of Sugarcane with SspPIP1;1 and SspPIP1;4 genes / Transformação genética de cana-de-açúcar com genes da aquaporina SspTIP1;1 e SspPIP1;4
A cana-de-açúcar vem assumindo um papel de destaque na atual conjuntura nacional, impulsionada principalmente pela produção de etanol, que vai de encontro com a crescente preocupação mundial na busca por fontes de energias renováveis e menos impactantes ao ambiente. Por essa razão, é preciso assegurar o contínuo desenvolvimento técnico-científico

7. RegeneraÃÃo "in vitro", estudos histolÃgicos e transformaÃÃo genÃtica da momoneira (Ricinus communis) / "In vitro" regeneration, histologycal studies and genetic transformation of castor-bean (Ricinus communis)
Castor bean (Ricinus communis) is an oilseed crop with considerable economic value because of the composition of its oil seed. However, there are some constraints in your use for human and animal food because of the presence of toxic and allergenic proteins. This problem could be solved or reduced through genetic engineering. However, this crop is recalcitra

8. Genetic transformation of sugarcane by biolistic and Agrobacterium tumefaciens to study the mechanism of programmed cell death / Transformação genética de cana-de-açúcar por biolística e Agrobacterium tumefaciens visando estudar o mecanismo de morte celular programada
Sugarcane is one of the main crops planted in Brazil and presents significant socioeconomic and agribusiness importance to the country. The world scene is quite favorable as regards the marketing of its two main products, sugar and alcohol, driving the development of the national sugar-alcohol sector. Therefore, the sugarcane genetic breeding appears as the

9. Caracterização de um begomovírus obtido de maracujazeiro (Passiflora edulis f. flavicarpa) e produção de clones infecciosos / Characterization of a begomovirus obtained from yellow passionfruit (Passiflora edulis f. flavicarpa) and production of infectious clones
Begomoviruses (family Geminiviridae) possess a circular, single-stranded DNA genome encapsidate in twinned icosahedral particles. They are vectored by the whitefly Bemisia tabaci and cause economically important diseases in several crops, mainly in tropical and subtropical regions. In Brazil, begomoviruses are major pathogens in common bean and tomato crops,

10. Brachiaria brizantha: caracterização de cDNA de ovários e identificação de explantes para transformação via biobalística
Brachiaria is a forage grass of great economic importance. Widely used as forage for cattle in Brazil, it is cultivated in about 70 million hectares. Its economic value is due to its adaptability to poor and acid soil, spittlebug and dry resistance and high nutritional quality. One limiting factor in Brachiaria breeding is apomixis, an assexual reproduction

11. Genetic transformation of Sorghum bicolor (L. Moench) aiming Al+3 tolerance / TransformaÃÃo genÃtica de Sorghum bicolor (L. Moench) visando tolerÃncia ao AlumÃnio.
The genetic transformation has been frequently associated with conventional genetic breeding programs. This technique allows the introduction of exogenous gene(s) into plant genomes, modifying specific characteristics. It can be an important supplementary tool for sorghum conventional breeding programs. However, most of the genetic transformation protocols r

12. Insertion of pr5k gene in sugar cane to induce resistant plants to rust disease fungi puccinia melanocephala. / Inserção do gene PR5K em cana-de-açúcar visando induzir resistência ao fungo da ferrugem Puccinia melanocephala.
The Sugar cane is very important culture for many countries especially Brazil. This culture however presents many problems with diseases; mainly rust disease that is spread mechanically and caused by Puccinia melanocephala fungi. The aim of this work was to get resistant plants with the gene PR5K , which is related to PR5 resistant proteins. Embriogenic call
