1. Resistance of maize landraces from Brazil to fall armyworm (Lepidoptera: Noctuidae) in the winter and summer seasons
ABSTRACT The fall armyworm (Spodoptera frugiperda) is a major maize (Zea mays L.) pest in Brazil, whose larvae cause losses from plant emergence to harvesting stage. This pest has been controlled almost exclusively with chemical insecticides and Bt plants (transgenics); however, resistance evolution has been detected to these two control tactics. Therefore,

2. Regulação do desenvolvimento e determinação do fruto de tomateiro (Solanum lycopersicum) pela via microRNA156/ SQUAMOSA Promoter-Binding Protein-Like (SPL) / MiR156targeted Squamosa Promoter-binding proteins (SPLs) regulate fruit development and determinacy
Many plants have indeterminate growth and are capable of producing new organs and tissues throughout their life. This capability is partially due to the highly regulated expression of specific genes such as SQUAMOSA Promoter-Binding Protein-Like (SPL) genes. SPLs encode plant-specific transcription factors that play important roles in development, such as ph

3. Biotecnologia de cana-de-açúcar (Saccharum spp.) para tolerância a estresse hídrico / Biotechnology of sugarcane (Saccharum spp.) for drought stress tolerance
O Brasil é o maior produtor mundial de cana-de-açúcar e no cenário atual, em que o aumento na busca por energia renovável é visível, o aumento na produtividade da cana é de extremo interesse para o setor sucroalcooleiro. Estresses abióticos influenciam grandemente a produtividade de espécies como a cana e, sendo assim, estudos relacionados com a te

5. 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

6. 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

7. 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

8. Antioxidant enzymes response to glyhosate herbicide application in transgenic and nottrangenic soybean "varieties" / Resposta de enzimas antioxidantes à aplicação do herbicida glifosato em variedades de soja transgênica e não transgênica
Herbicides are applied in cultures with the objective to eliminate weeds, but the effects over the plants sometimes are not perceptible or are not widely considered. Plants under stress conditions can react to the elicitor with oxidative manifestations where reactive oxygen species (ROS) are generating. Glyphosate acts as a competitive inhibitor of enolpiruv

9. Enhanced Selenium Tolerance and Accumulation in Transgenic Arabidopsis Expressing a Mouse Selenocysteine Lyase1
Selenium (Se) toxicity is thought to be due to nonspecific incorporation of selenocysteine (Se-Cys) into proteins, replacing Cys. In an attempt to direct Se flow away from incorporation into proteins, a mouse (Mus musculus) Se-Cys lyase (SL) was expressed in the cytosol or chloroplasts of Arabidopsis. This enzyme specifically catalyzes the decomposition of S

10. Enhanced Photosynthetic Performance and Growth as a Consequence of Decreasing Mitochondrial Malate Dehydrogenase Activity in Transgenic Tomato Plants1
Transgenic tomato (Solanum lycopersicum) plants expressing a fragment of the mitochondrial malate dehydrogenase gene in the antisense orientation and exhibiting reduced activity of this isoform of malate dehydrogenase show enhanced photosynthetic activity and aerial growth under atmospheric conditions (360 ppm CO2). In comparison to wild-type plants, carbon

11. Pea DNA helicase 45 overexpression in tobacco confers high salinity tolerance without affecting yield
Salt tolerance is an important trait that is required to overcome salinity-induced reduction in plant productivity. We have reported previously the isolation of a pea DNA helicase 45 (PDH45) that exhibits striking homology with the eukaryotic translation initiation factor eIF-4A. Here, we report that PDH45 mRNA is induced in pea seedlings in response to high

12. Plant nuclear gene knockout reveals a role in plastid division for the homolog of the bacterial cell division protein FtsZ, an ancestral tubulin
Little is known about the division of eukaryotic cell organelles and up to now neither in animals nor in plants has a gene product been shown to mediate this process. A cDNA encoding a homolog of the bacterial cell division protein FtsZ, an ancestral tubulin, was isolated from the eukaryote Physcomitrella patens and used to disrupt efficiently the genomic lo
