37. Soybean genetic transformation: a valuable tool for the functional study of genes and the production of agronomically improved plants
Transgenic plants represent an invaluable tool for molecular, genetic, biochemical and physiological studies by gene overexpression or silencing, transposon-based mutagenesis, protein sub-cellular localization and/or promoter characterization as well as a breakthrough for breeding programs, allowing the production of novel and genetically diverse genotypes.

38. Avaliação dos lipídeos de membrana e das ORFs dos contratransportadores Na+/H+ e Na+/Ca2+ associados a mecanismos de adaptação à halofilia em Halococcus morrhuae
Soil saliniy is a major factor in reducing plant growth and, consequently, their agricultural productivity. Most of the studies in the literature presents a strategy for reducing the effects of improving salt tolerance in plants for the production of osmolytes and stress proteins, and there are few studies aimed at increasing salt tolerance by restoring ioni

39. Sistema de inovação em plantas transgênicas no Brasil : estratégias para garantir a competitividade nacional neste setor
The starting idea for the formulation of this thesis was that innovation in the form of transgenic plants has very promising opportunities in the Brazilian agriculture and possibily a high impact in its economic development. The agriculture market has a turnover of billions of dollars in the national economy and Brazil is already the second largest producer

40. Efeito do gene CP4 EPSPS na produtividade de óleo em populações de soja / Effect of CP4 EPSPS gene on the oil yield of soybean populations
During the past few years, with the increase of the biodiesel international price and rising demand, there has been a larger interest in increasing the oil content of soybean cultivars. It is known that the high oil production is a function of yield. However, there are many factors that prevent cultivars from expressing their full yield potential, for exampl

41. Caracterização de determinantes genéticos envolvidos na qualidade industrial e nutricional do fruto de tomate / Characterization of genetic determinants involved in industrial and nutritional quality of tomato fruit
This thesis addresses tomato fruit metabolism analysis by using three complementary approaches: i) the identification of candidate genes co-located with QTL previously described from metabolic profiles of S. lycopersicum (cv. M82) and S. pennellii introgressed lines, associated with industrial and nutritional quality traits; ii) the structural analyses of th

42. Transgenic plants of Petunia hybrida harboring the CYP2E1 gene efficiently remove benzene and toluene pollutants and improve resistance to formaldehyde
The CYP2E1 protein belongs to the P450 enzymes family and plays an important role in the metabolism of small molecular and organic pollutants. In this study we generated CYP2E1 transgenic plants of Petunia using Agrobacterium rhizogenes K599. PCR analysis confirmed that the regenerated plants contained the CYP2E1 transgene and the rolB gene of the Ri plasmid

43. A simple and reliable method for the screening of transgenic tobacco plants.
Even though much improvement has been made in plant transformation methods, the screening of transgenic plants is often a laborious work. Most approaches for detecting the transgene in transformed plants are still time-consuming, and can be quite expensive. The objective of this study was to search for a simpler method to screen for transgenic plants. The in

44. Agronomic performance, chromosomal stability and resistance to velvetbean caterpillar of transgenic soybean expressing cry1Ac gene.
The objective of this work was to analyze the agronomic performance and chromosomal stability of transgenic homozygous progenies of soybean [Glycine max (L.) Merrill.], and to confirm the resistance of these plants against Anticarsia gemmatalis. Eleven progenies expressing cry1Ac, hpt and gusA genes were evaluated for agronomic characteristics in relation to

45. Plantas transgênicas e a microbiota do solo.
ABSTRACT: Soil micro-organisms represent a key hole in the nutrient cycle and in the maintenance of the fertility, besides execute another variety of important functions for the plants and the environment. With the possibility of the transgenic crops to cause negative impacts on the soil microbial communities, emerge the necessity to deep evaluate the real e

46. 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

47. Transformação de plantas.
ABSTRACT: During centuries mankind plants to obtain cultivars with superior characteristics. However, conventional methods of plant breeding present limitations. The development of transformation methods created possibilities of great progresses in plant breeding because it offers the opportunity to introduce exogenous genes into superior cultivars to obtain

48. The promoter of a gene encoding an isoflavon reductase-like protein in coffee (Coffea arabica) drives a stress-responsive expression in leaves.
A cDNA clone (designated CaIRL) encoding an isoflavone reductase-like protein from coffee (Coffea arabica) was retrieved during a search for genes showing organ/tissue-specific expression among the expressed sequence tags (EST) of the Brazilian coffee EST database. The CaIRL cDNA contains a single open reading frame of 946 nucleotides (nt) encoding 314 amino
