| ABSTRACT Among the options to control Alabama argillacea (Hübner, 1818) and Heliothis virescens (Fabricius, 1781) on cotton, insecticide spraying and biological control have been extensively used. The GM'Bt' cotton has been introduced as an extremely viable alternative, but it is yet not known how transgenic plants affect populations of organisms that are interrelated in an agroecosystem. For this reason, it is important to know how the spatial arrangement of pests and beneficial insect are affected, which may call for changes in the methods used for sampling these species. This study was conducted with the goal to investigate the pattern of spatial distribution of eggs of A. argillacea and H. virescens in DeltaOpalTM (non-Bt) and DP90BTMBt cotton... |

| 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 TC1507 were detected in most of the samples, and NK603 was present only in the samples analyzed in 2012. The authorized lines GA21, T25, and the unauthorized Bt176 were not detected. All positive samples in the qualitative tests collected in 2011 showed a transgenic content higher than 1%, and none of them was correctly labeled. Regarding the samples collected in 2012, all positive samples were... |

| The increasing presence of products derived from genetically modified (GM) plants in human and animal diets has led to the development of detection methods to distinguish biotechnology-derived foods from conventional ones. The conventional and real-time PCR have been used, respectively, to detect and quantify GM residues in highly processed foods. DNA extraction is a critical step during the analysis process. Some factors such as DNA degradation, matrix effects, and the presence of PCR inhibitors imply that a detection or quantification limit, established for a given method, is restricted to a matrix used during validation and cannot be projected to any other matrix outside the scope of the method. In Brazil, sausage samples were the main class of... |

| Abstract This paper draws on the importance of science-based agriculture in order to throw light on the way scientific achievements are at the basis of modern civilization. An overview of literature on plant biotechnology innovations and the need to steer agriculture towards sustainability introduces a series of perspectives on how plant biotech can contribute to the major challenge of feeding our super population with enough nutritious food without further compromise of the environment. The paper argues that science alone will not solve problems. Three major forces - science, the economy and society - shape our modern world. There is a need for a new social contract to harmonize these forces. The deployment of the technologies must be done on the basis of... |

| The coat protein (CP) gene of the potato virus Y strain "o" (PVY O) was introduced into potato, cultivar Achat, via Agrobacterium tumefaciens-mediated transformation. Sixty three putative transgenic lines were challenged against the Brazilian strains PVY-OBR and PVY-NBR. An extremely resistant phenotype, against the two strains, was observed in one line, denominated 1P. No symptoms or positive ELISA results were observed in 16 challenged plants from this line. Another clone, named as 63P, showed a lower level of resistance. Southern blot analysis showed five copies of the CP gene in the extremely resistant line and at least three copies in the other resistant line. The stability of the integrated transgenes in the extreme resistant line was examined during... |

| Two transgenic potato clones of cv. Achat, denominated 1P and 63P were challenged with two Potato virus Y strains (PVY O and PVY N), under greenhouse conditions, to be evaluated for resistance to these strains. Optical density values of the Elisa readings of samples from the transgenic plants were compared to readings from samples of the inoculated non-transformed plants. Clone 1P was extremely resistant to both PVY strains, reflected by not being systemically infected. Clone 63P, however, presented partial resistance to both PVY strains as local or systemic infection was delayed in some days. These results confirm the previously reported extreme resistance to PVY of clone 1P. |

| A bibliographic database of scientific papers published by authors affiliated to research institutions worldwide, especially focused in Europe and in the European Atlantic Area, and containing the keywords “microalga(e)” or “phytoplankton” was built. A corpus of 79,020 publications was obtained and analyzed using the Orbit Intellixir software to characterize the research trends related to microalgae markets, markets opportunities and technologies that could have important impacts on markets evolution. Six major markets opportunities, the production of biofuels, bioplastics, biofertilizers, nutraceuticals, pharmaceuticals and cosmetics, and two fast-evolving technological domains driving markets evolution, microalgae harvesting and extraction technologies... |

| Polyploids can be defined as organisms with one or more additional chromosome sets with respect to the number most frequently found in nature for a given species. Triploids, organisms with three sets of homologous chromosomes, are found spontaneously in both wild and cultured populations and can be easily induced in many commercially relevant species of fish and shellfish. The major consequence of triploidy is gonadal sterility, which is of advantage in the aquaculture of molluscs since it can result in superior growth. In fish, the induction of triploidy is mainly used to avoid problems associated with sexual maturation such as lower growth rates, increased incidence of diseases and deterioration of the organoleptic properties. Triploidy can also be used... |

| Measures are being developed and implemented enabling the co-existence of conventional, genetically modified (GM) and organic cropping systems. In order to segregate GM from conventional crops in the entire supply chain, a food or feed company has to reorganise its production. This may involve for dedication of the production line to non-GM, or production can be organised on the same plant, using spatial or temporal segregation. In practice, only the latter method is used in the feed industry, as no investments in new machinery are necessary in the case. The segregation and identity preservation of GM and non-GM crops has to be well organised. An important tools used to proof the identity of the imported raw materials is the batch or product declaration... |

| Seit der ersten Aussaat 1996 in den USA nimmt die Anbaufläche transgener Pflanzen jährlich stetig zu und 2005 wurden weltweit auf 90 Mio. ha transgene Pflanzen angebaut. In der EU wurden in den letzten Jahren umfangreiche gesetzliche Regelungen erlassen, welche die Zulassung, die Kennzeichnung und das Monitoring gentechnisch veränderter Organismen (GVO) regeln. In der vorliegenden Studie wurde untersucht, welche Konsequenzen der weltweite Anbau gentechnisch veränderter Pflanzen, unter Beachtung der europäischen Gentechnikgesetzgebung, für die Lebens- und Futtermittelindustrie in Deutschland hat. Empirische Grundlage ist eine umfassende schriftliche Befragung, die 2005 durchgeführt wurde. Das Ergebnis dieser Studie zeigt, dass vor allem Rohstoffimporte aus... |

| Until there is a successful challenge at the WTO, the EU policy on LLP is likely to remain in place. Under this policy, there is a zero tolerance level for GM material that has not received EU authorization. Zero tolerance, however, has to be operationalized – what does an exporting country have to do to prove it is in compliance with zero tolerance? The Protocol on Triffid flax was formally proposed by the Canadian flax industry, not the Canadian government, and accepted by the European Commission. It entails an extensive and costly testing regime all along the flaxseed supply chain. Canadian exports of flaxseed have resumed to the EU. The Protocol provides sufficient transparency for firms to be willing to engage in international transactions. This... |
