1. Contamination of corn grain for human consumption with transgenic sequences in Paraguay
Abstract Corn is one of the most important economic, social and cultural agricultural products in Paraguay, being the main ingredient of several typical foods. Due to the cross-pollination of this plant, it can be contaminated with transgenic maize pollen found in nearby fields. The general objective of this research was to evaluate the presence of transgeni

2. The role of fetal-maternal microchimerism as a natural-born healer in integrity improvement of maternal damaged kidney
ABSTRACT Purpose: To identify the fetal stem cell (FSC) response to maternal renal injury with emphasis on renal integrity improvement and Y chromosome detection in damaged maternal kidney. Materials and Methods: Eight non-green fluorescent protein (GFP) transgenic Sprague-Dawley rats were mated with GFP-positive transgenic male rats. Renal damage was indu

3. Performance of transgenic and conventional soybean plants subjected to bioassay for detection of glyphosate tolerant seeds
Abstract The adoption of genetically modified soybean cultivars is increasing annually around the world, which indicates the excellence of these genotypes. For soybean breeding, the use of such cultivars in a backcross program relies on the ability to detect the transgenic trait. The germination test in a moistened substrate with glyphosate is effective and

4. Molecular characteristics, recombinant expression and activity detection of OsGSTL1 from rice
The mRNA of OsGSTL1 was detected in the roots and leaves of rice plants at seedling and tillering stages, and their roots, leaves and panicles at the heading stage. The full-length open reading frame of OsGSTL1 cDNA was 732 bp and encoded a putative polypeptide of 243 amino acids with a calculated molecular mass of 27.30 kDa and a theoretical pI of 5.50. The

5. Detection of genetically modified maize events in Brazilian maize-derived food products
The Brazilian government has approved many transgenic maize lines for commercialization and has established a threshold of 1% for food labeling, which underscores need for monitoring programs. Thirty four samples including flours and different types of nacho chips were analyzed by conventional and real-time PCR in 2011 and 2012. The events MON810, Bt11, and

6. Bioassay for detection of transgenic soybean seeds tolerant to glyphosate.
Glyphosate is a systemic, nonselective, postemergence herbicide that inhibits growth of both weeds and crop plants. Once inside the plant, glyphosate interferes with biosynthesis of aromatic amino acids phenylalanine, tyrosine, and tryptophan, by inhibiting the activity of 5-enolpyruvylshikimate-3-phosphate synthase (EPSPS), a key enzyme of the shikimate pat

7. 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

8. Proteomic, enzymatic and metalloproteomic aspects of transgenic and non-transgenic soybean seec / Aspectos proteomicos, enzimaticos e metaloproteomicos em sementes de soja transgenica e não-transgenica
In this work, transgenic and non-transgenic soybean seeds were studied, being the Roundup Ready® (RR) type, the soybean genectically modified, to which the insertion of the gene make the plant resistent to herbicides that present the glifosate as active principle. The proteomic, enzimatic and metal profiles were evaluated in the soybean seeds to contribute

9. Transformação genética de abobrinha-de-moita e melancia para resistência ao Papaya ringspot virus - type Watermelon e ao Zucchini yellow mosaic virus / Genetic transformation of zucchini squash and watermelon for resistance to Papaya ringspot virus - type W and Zucchini yellow mosaic virus
Diseases caused by the potyviruses Papaya ringspot virus - type Watermelon (PRSV-W) and Zucchini yellow mosaic virus (ZYMV) significantly reduce the yield and fruit quality of zucchini squash (Cucurbita pepo), watermelon (Citrullus lanatus), as well as other cucurbit crops in Brazil. The purpose of this work was to obtain zucchini squash and watermelon trans

10. Genic transfer in sperm cells in Mus musculus and Ramdia quelem / Transferência gênica em células espermáticas de Mus musculus e Ramdia quelen
Transgenic animals have been used as biological models in studies of the genes functions and their mechanisms of action, as well as to improve animal production. Researchers are trying to produce transgenic animals that will be organs donors in xenotransplants. Another use of the transgenic animal is in the production of recombinant proteins for pharmaceutic

11. Rastreabilidade de soja Roundup Ready® em produtos agrícolas e derivados: produção de materiais de referência e uso de marcadores AFLP / Roundup Ready® transgenic soybean traceability in agrifood products and derivatives: reference materials production and the use of AFLP markers
The introduction of soybean transgenic cultivars brought several changes in both world trade and regulation rules for producers and consumers, mainly in relation to certification, traceability, biosafety and labeling. Soybean is one of the largest commodities in the world trade and responsible for half of the Brazilian export incomings, present as raw materi

12. Characterization and utilization of genes involved with aluminum tolerance in maize / Caracterização e utilização de genes envolvidos na tolerancia ao aluminio toxico em milho
Acid soils are found worldwide but most of them are located in tropical and subtropical regions. Aluminum (Al), the most abundant metal on the earth surface, becomes soluble in the soil solution as consequence of low pH in acid soils and achieves phytotoxic levels for most of the cultivated plant species. The first symptom of Al toxicity is the inhibition of
