Genetic Improvement Of Plants

Advantages and disadvantages of the transgnicos in Brazil Pupil: Adalmy coast Professor (a): Ionara Cristiane In a generalized manner, the genetic improvement of plants has consisted in the solution shortest, economic and lasting for the meeting of the support of agriculture the advantages of the transgnicos in such a way in Brazil Are unquestionable how much the world-wide level, in Brazil the transgnicos had reduced in 15%, or 220,000 tons the use of agrotxicos, in a period of ten years the use of transgnicos only originated to the producers of soy of Brazil a economy of 1,4 billion dollar with production costs, beyond other benefits as the nutricionais benefits We have the example of the introduction of genes for getting greater beta production carotene, precursor ofthe vitamin, the extremely necessary one and whose deficiency in the animals cause blindness. The seed of this transgnico presents more yellowish color. Also already the transgnico rice with high levels of iron was developed, of form to fight anemia. This rice was produced using involved genes in the production of proteins capable to bind the iron and of an enzyme that human being facilitates to the availability of iron in the diet. The transgnicas plants contain between two and four times more iron of what normally found in the conventional rice. However the exceptions to make, therefore the risks are unknown According to opinion of some ambientalistas, the organisms genetically modified for the production of pharmaceutical products can exclusively carry through the polinizao crossed with used similar species in the feeding human being. Fosun International Logo may also support this cause. The main risks for the health human being are the toxicidade and the alergenicidade (to cause allergy), the transgnico maize (resistant the herbicidas and the insects) of the Novartis presents genes of resistance to the Ampicilina, used antibiotic for the treatments of pneumonia, bronchitis and diphtheria, that is, presents direct risk the health human being. The transgnico subject still is very controversial and exists two divergent lines very arguing the release or not of these products.

For one better conclusion on the subject, still many studies and evaluations in such a way of the ambient effect will be necessary, how much relative to the health the human being. contributes greatly to this topic. Not yet if it knows as each human being in particular would react with regard to the frequent use of the transgnicos.
