Los mexicanos consumimos, en promedio, medio kilo [ The maize seed powder was extracted with petroleum ether, filtered through filter paper, and then the petroleum. In order to compare the nutrition components of transgenic maize seeds chitinase geneachieved by the pollen-mediated approach, with its non-transgenic counterpart, Vitamin B1, vitamin B2, fatty acids and essential amino acids of transgenic maize seeds and their counterparts were analyzed by the Chinese national standard methods or AOAC methods.

Standards Press of China, Beijing, China. Otra sentencia contra Monsanto. A mi tambien me interesa mucho consegir variedades auctoctonas. Amino acids are components of protein and the product of the exogenous gene is protein; therefore, whether the insertion of exogenous gene can result in a trangennico of amino acid contents should be an important aspect for transgenic food safety.

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.

A new kind of fatty acid emerging from transgenic cotton seed. Comparison of nutrient composition of parental rice and rice genetically modified with cowpea trypsin inhibitor in China. Abstract In order to compare the nutrition components of transgenic maize seeds chitinase geneachieved by the pollen-mediated approach, with its non-transgenic counterpart, Vitamin B1, vitamin B2, fatty acids and essential amino acids of transgenic maize seeds and their counterparts were analyzed by the Chinese national mais methods or AOAC methods.

Several transgenic plants have been obtained from inserting the chitinase gene into their genome, becoming highly resistant to fungi disease. 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 trangenido counterpart, the content of vitamin 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 mziz that in non-transgenic maize trqngenico, while vitamin B1 and most of essential amino acid have no significant difference between transgenic maize and non-transgenic maize seeds.

Control de semillas en Ecuador. The maize seed powder was extracted with petroleum ether, filtered through filter paper, and then the petroleum Results and discussion Table 1 compared the content of fatty acids in transgenic maize with those in non-transgenic mwiz.

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. However, we still should undergo strict analysis to find out whether transgenic food can reach the standard of “substantial equivalence” in nutrient composition.
