1. First record of Peridroma saucia Hübner (Lepidoptera: Noctuidae) in transgenic soybeans
ABSTRACT The widespread cultivation of transgenic soybeans has caused significant changes in the spectrum of Lepidoptera larvae, both in the number of species as well as on their densities in the field. Transgenic crops producing Bacillus thuringiensis (Bt) insecticidal proteins have successfully reduced the incidence of the most common caterpillars infestin

2. Bioenergetics Potential of RR2 PRO Transgenic Soybean Subjected to Application of Herbicides Isolated and in Combination
ABSTRACT In Brazil, there are several crops producing oil for biofuel production, such as canola, sunflower, peanut, cotton, castor bean, soybean, among others. There are parameters that indicate the energetic and economic viability for the production of biofuels, and that can be applied, for example, in transgenic soybeans. The present study aimed to evalua

3. pGVG: a new Gateway-compatible vector for transformation of sugarcane and other monocot crops
Abstract The successful development of genetically engineered monocots using Agrobacterium-mediated transformation has created an increasing demand for compatible vectors. We have developed a new expression vector, pGVG, for efficient transformation and expression of different constructs for gene overexpression and silencing in sugarcane. The pCAMBIA2300 bin

4. Nutrient Uptake by High-Yielding Cotton Crop in Brazil
ABSTRACT: Determining nutrient uptake and accumulation rates by cotton crops is important to define management strategies, especially for transgenic varieties, which are cultivated using high-technology approaches that require substantial investment to maximize yield. Currently in Brazil, the states of Bahia and Mato Grosso are responsible for 84.4 % of the

5. Isolation and characterization of a promoter responsive to salt, osmotic and dehydration stresses in soybean
Abstract Drought stress is the main limiting factor of soybean yield. Currently, genetic engineering has been one important tool in the development of drought-tolerant cultivars. A widely used strategy is the fusion of genes that confer tolerance under the control of the CaMV35S constitutive promoter; however, stress-responsive promoters would constitute the

6. Does Bt maize cultivation affect the non-target insect community in the agro ecosystem?
ABSTRACT The cultivation of genetically modified crops in Brazil has led to the need to assess the impacts of this technology on non-target species. Under field conditions, the potential effect on insect biodiversity was evaluated by comparing a homogeneous corn field with conventional and transgenic maize, expressing different Bt proteins in seven counties

7. Sistema de inovação em plantas transgênicas no Brasil : estratégias para garantir a competitividade nacional neste setor
The starting idea for the formulation of this thesis was that innovation in the form of transgenic plants has very promising opportunities in the Brazilian agriculture and possibily a high impact in its economic development. The agriculture market has a turnover of billions of dollars in the national economy and Brazil is already the second largest producer

8. Plantas transgênicas e a microbiota do solo.
ABSTRACT: Soil micro-organisms represent a key hole in the nutrient cycle and in the maintenance of the fertility, besides execute another variety of important functions for the plants and the environment. With the possibility of the transgenic crops to cause negative impacts on the soil microbial communities, emerge the necessity to deep evaluate the real e

9. Biossegurança ambiental de OGMs.
ABSTRACT: In 2005, there were 90 million hectares cultivated with GMOs by 8.5 million producers in 21 countries. In 2006, we commemorated 10 years of commercial production of GMOs. Currently there are 10 million farmers planting 100 million hectares. However, several points were raised concerning the environmental impact of GMOs: (1) risk of cultivated or wi

10. Gene flow of genetically modified soybeans, in summer and winter sowings, with isolations of soybean or maize / Fluxo gênico de soja geneticamente modificada, em semeaduras de verão e de inverno, com isolamentos de soja ou milho
Genetically modified soybean, tolerant to glyphosate, expanded its growing area in few years becoming the most sown in the country. The advantages of its use are many compared to the conventional soybean, which has led soybean farmers to prefer it. However, since some markets still prefer conventional soybean and its production occurs in smaller areas, there

11. Análises moleculares das vias de sinalização de morte celular originadas no retículo endoplasmático / Molecular analyses of cell death pathways signalling originated in the endoplasmic reticulum
Abiotic and biotic stresses are responsible for major losses in agricultural productivity world wise. Therefore, the understanding of mechanisms of plant stress response and adaptation to such conditions should provide the foundation for engineering plant stress tolerance and hence maximizing the yield of crops growing under adverse environmental conditions.

12. Impacto do cultivo da soja resistente ao glyphosate sobre artrópodes e componentes de produção da cultura / Impact of soybean crops resistant to glyphosate on arthropods and components of plant yield
The global area planted with transgenic crops was 125 million hectares in 2008. Of this total, 53% was occupied by soybean modified for tolerance to glyphosate. The rapid acceptance of this technology is due to high efficiency, low cost and easy to implement. However, the abuse use of a broad spectrum herbicide can cause direct and indirect impacts. The dire
