Genetic diversity among plants of non-transgenic and transgenic versions of a single cross maize hybrid
(Elsevier Science, 2015-05)
Previous studies have documented that transgene introduction may alter the phenotypic expression of several traits (e.g., biomass production, grain yield). We hypothesized that genetic diversity could influence the phenotypic ...
Effect of Bt zygosity in transgenic maize hybrids to the non-target pest Dalbulus maidis
The corn leafhopper Dalbulus maidis causes corn production losses mainly by acting as vector of pathogenic mollicutes and virus. Transgenic technologies that encode insecticidal proteins from Bacillus thuringiensis (Bt) ...
Sequence similarity between the viral cp gene and the transgene in transgenic papayas.
(Pesquisa Agropecuária Brasileira, Brasília, v.40, n. 5, p.479-486, maio 2005., 2005)
Detecting adventitious transgenic events in a maize center of diversity
(Pontificia Universidad Católica de ValparaísoChile, 2011-07-15)
Background: The genetic diversity of maize in Peru includes several landraces (within race clusters) and modern open pollinated and hybrid cultivars that are grown by farmers across various regions, thereby making this ...
Expressão de Cry1F, controle de Spodoptera frugiperda (Lepidoptera: Noctuidae) e produtividade de grãos em híbridos de milho homozigotos e hemizigotos transgênicos
(Universidade Estadual Paulista (Unesp), 2017-02-20)
Os híbridos de milho transgênicos, em geral, apresentam o locus transgênico em hemizigose. O objetivo do trabalho foi avaliar o efeito do número de alelos transgênicos em híbridos de milho em relação à expressão de Cry1F ...
Homozygosis of Bt locus increases Bt protein expression and the control of Spodoptera frugiperda (Lepidoptera: Noctuidae) in maize hybrids
Spodoptera frugiperda (J.E. Smith) is the main pest of maize in Brazil and its control has been targeted by Bt maize hybrids. Generally, Bt maize hybrids possess the transgenic locus in a hemizygous condition, that is, ...
Evidence of gene flow between transgenic and non-transgenic maize in Colombia
(Universidad Nacional de Colombia, 2015-09-01)
Maize (Zea mays) is an important crop worldwide and is essential for industry. Many transgenic cultivars of maize have been developed over the years from this species, producing cultivars resistant to herbicides and insects, ...
Transgene escape and persistence in an agroecosystem: the case of glyphosate-resistant Brassica rapa L. in central Argentina
Brassica rapa L. is an annual Brassicaceae species cultivated for oil and food production, whose wild form is a weed of crops worldwide. In temperate regions of South America and especially in the Argentine Pampas region, ...
DAMAGES CAUSED BY Dichelops melacanthus (Heteroptera: Pentatomidae) IN CONVENTIONAL AND TRANSGENIC CORN HYBRIDS
(Univ Federal Uberlandia, 2015-07-01)
This study evaluated the symptoms of attack by the green belly stink bug, Dichelops melacanthus (Dallas, 1851), in conventional and transgenic commercial corn (Zea mays) hybrids, the seeds of which were either treated using ...
