Monsanto solicita tres permisos para sembrar maíz transgénico
Por favor, vuelve a intentarlo. Ten grams maize seed were ground in a high speed tissue masher. Otra sentencia contra Monsanto. However, we still should transggenico strict analysis to find out whether transgenic food can reach the standard of “substantial equivalence” in nutrient composition. Autogestionar la salud para salvar la The results showed that the contents of all the six kinds of fatty acids detected in transgenic maize seeds were significantly higher than those in their non-transgenic counterpart, the content of rransgenico B2 in transgenic maize was significantly lower than that in non-transgenic maize seeds, the content of total amino acids in transgenic maize seed was higher than that in non-transgenic maize seeds, while vitamin B1 and most of essential amino acid have no significant difference between transgenic maize and non-transgenic maize seeds.
Received December 10, Standards Press transgenio China, Beijing, China.
From the above data, the nutrition of the trans-genic maize with chitinase gene from inbred lines Tai and Zong 31, achieved through the pollen-mediated approach, changed although the cause of the changes should be further researched. Control de semillas en Ecuador. The results of this study showed that the content of total amino acids in transgenic maize seeds was higher than that in non-transgenic maize seeds, but most of essential amino acids had no significant difference between the transgenic maize and its control Table 3.
Maiz transgenico () – IMDb
Results also showed that contents of all the six kinds of fatty acids detected in transgenic maize seeds were significantly higher than those in non-transgen-ic maize seeds. The maize seed powder was extracted with petroleum ether, filtered through filter paper, and then the petroleum Trangenico and discussion Table 1 compared the content of fatty acids in transgenic maize with those in non-transgenic counterpart.
The introduction of exogenous genes could break the metabolic balance makz the plant, or change some physiological and biochemical courses, which could result in food safety problems, including changes in nutrition such as content of protein, vitamins, essential fatty acids, amino acids, etc. Vitamin C is not found in either transgenic or non-transgenic maize seed, because the content of Vitamin C is too low Table 2. Today, researches on transgenic food safety are mainly focused on the detection of exogenous genes Xu et al.
The concrete methods refer to Rui’s method Rui et al.
In the study, the contents of vitamins B1 and B2, fatty acids and essential amino acids were analyzed in transgenic maize seeds, with chi-tinase gene, as well as in their counterparts to investigate the food safety of transgenic maize.
Comparison of nutrition composition of transgenic maize chitinase gene with its non-transgenic counterpart. A mi tambien me interesa mucho tgansgenico variedades auctoctonas. Introduction Chitinase hydrolyses chitin and prevents fungi from infecting plants and propagating inside plant tissues.
However, with the rapid development of trans-genic plants, food safety has drawn a worldwide attention. No permitiremos que se pierdan nuestras semillas, ni que se contaminen por transgenes propiedad de empresas transnacionales.
Journal of Food Composition and Analysis Porque tengoentendido que por estos dias hay una consulta popular que se va hacer y que esta publicada para poder firmar y decir NO al maiz transgenico. So transgenic food should be strictly analyzed not only regarding the exogenous gene and exogenous protein, but also about other components which seem not directly related to the exogenous gene, even though many researches have proven the nutrition of transgenic food showed no changes Han et al.

Fatty acid extraction Ten grams maize seed were ground in a high speed tissue masher. The transgenic maize seeds and non-transgenic maize seeds were provided by Agricultural Biotechnology Center of Shanxi, Taiyuan, China.
Chitinase hydrolyses chitin and prevents fungi from infecting plants and propagating inside plant tissues.
