title: Comparison of nutritional quality between Chinese indica rice with sck and cry1Ac genes and its nontransgenic counterpart.
abstract: Nutritional assessment of transgenic crops used for human food and animal feed is an important aspect of safety evaluations. An insect-resistant rice (IRR) was generated by the stable insertion of sck, a modified cowpea trypsin inhibitor gene, and cry1Ac, encoding a crystal protein from Bacillus thuringiensis into the genome of a common variety of Chinese indica rice. The composition of the brown and milled rice grain from the resulted IRR line designated Liangyou Kefeng No. 6 was compared with that of the parental rice cultivar Liangyou 2186. Nutrients, including the proximates, amino acids, fatty acids, minerals, and vitamins, were measured. The antinutritive components such as phytic acid, lectin, and trypsin inhibitors were also examined. The data demonstrated that the nutritional quality of both the brown and milled rice grains from the transgenic line was substantially equivalent to that of the nontransgenic counterpart, and measured amounts of nutritional components fell within the range of values reported for other commercial lines.
