- Abstract
- As a part of a safety assessment of new transgenic crops, compositional equivalence studies between transgenic crops with non-transgenic comparators are almost universally required. This study was conducted to compare nutritional profiles of proximate composition, and fatty acid, amino acid, mineral, and vitamin contents, and anti-nutrients, between transgenic drought-tolerant Agb0103 rice harboring the pepper methionine sulfoxide reductase B2 gene CaMsrB2 and the parental rice cultivar, 'Ilmi' as a non-transgenic control. Both transgenic and non-transgenic rice were grown and harvested in 2 different locations. Proximate compositions of moisture, starch, protein, lipid, and ash content of Agb0103 rice were similar to parental non-transgenic rice. There were no differences between transgenic and non-transgenic rice with respect to the whole nutritional composition, except for minor locality differences for a few nutritional components. Agb0103 rice with improved resistance to drought is nutritionally equivalent to the parental rice cultivar.
