14. Agrobacterium-mediated genetic transformation of 'Hamlin' sweet orange.
The development and optimization of efficient transformation protocols is essential in new citrus breeding programs, not only for rootstock, but also for scion improvement. Transgenic 'Hamlin' sweet orange (Citrus sinensis (L.) Osbeck) plants were obtained by Agrobacterium tumefaciens-mediated transformation of epicotyl segments collected from seedlings germ

15. 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

16. Avaliação qualitativa e quantitativa da microbiota do solo e da fixação biológica do nitrogênio pela soja.
O objetivo deste trabalho foi definir, para as condições edafoclimáticas do Brasil, níveis aceitáveis de dispersão de alguns parâmetros biológicos, utilizados em estudos de impacto ambiental de novas tecnologias usadas na cultura da soja. Dois ensaios com soja convencional e transgênica foram conduzidos em 11 municípios de seis estados e no Distrit

17. Biossegurança de alimentos transgênicos.
ABSTRACT: The use of transgenic plants on the human diet is a matter of great concern for the scientific community and the public in general. However, it is important to consider that before the release for human consumption, transgenic foods are submitted to an extensive series of rigorous tests. These tests includes the characterization of the expressed pr

18. Transgenia agrícola e modernidade : um estudo sobre o processo de inserção comercial de sementes transgênicas nas sociedades brasileira e argentina a partir dos anos 1990 / Transgenics in agriculture and modernity : a study of the commercial introduction of transgenic seeds into the Brazilian and Argentinean societies since 1990
The commercial use of transgenic seeds in agriculture since the end of the 20th century and its disseminated use in the beginning of the 21st century lead not only to radical changes in the world s agriculture sector, now technologized in all spheres of the productive process, but also to radical changes into the concepts of seeds and life, with economic, so

19. Biotecnologias agrícolas e sociedade: disputas sociais e regulamentação dos transgênicos no Brasil (19852005)
In this dissertation we present an historical panorama of the introduction of genetically modified organisms (transgenics) in Brazil, its repercussion and the social debate about several controverse aspects of this new technological product. In front of every groups view, we argued regarding the ambiguous centrality of technology at the contemporaneous world

20. Ciência e risco : as controvérsias como procedimento da comunicação pública num contexto democrático
This work investigates the consolidation of the scientific controversy as a subject of news in the democratic context, under the point of view of a public research organization. Based on the existing concepts of risk communication and organizational communication, this research defends that the traditional models of communication with society - focused primo

21. Segurança alimentar e governança para transgenicos : um estudo sobre o ativismo transnacional / Food safety and governance : a study on transnational activism
Global governance can be described as a series of arrangements among actors of the international system, which take on the form of a "web" of control mechanisms. It verifies that an objective of large non-government organizations is to influence international politics through the implementation of actions in this plan. However, access to the most effective s

22. Adaptabilidade de híbridos entre Gossypium barbadense E G. hirsutum N contendo o gene cry1Ac
Hybrids among transgenic plants and related species are expected to occur if they are sympatric and when there are not crossing barriers; as is the case, in Brazil, of cry1Ac transgenic cotton and Gossypium barbadense. This species has been maintained as dooryard plants, and should be preserved as a genetic resource. Hybrids were evaluated about traits relat

24. Controle genético de mosquitos Culex quinquefasciatus / Genetic control of Culex quinquefasciatus mosquitoes
The Culex quinquefasciatus mosquitoes are considered urban plague and are able to grown in polluted water achieving high density. This specie are important vectors in the transmission of parasites and arbovirus. Chemical control methods shown to be ineffective and highly hazards to the environment. In this way, new technologies of control have been developed
