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 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.
作为新转基因作物安全性评估的一部分，几乎普遍要求对转基因作物与其非转基因对照进行成分等效性研究。本研究旨在比较携带辣椒蛋氨酸亚砜还原酶B2基因的转基因耐旱Agb0103水稻与作为非转基因对照的亲本水稻品种‘Ilmi’之间的近似成分、脂肪酸、氨基酸、矿物质和维生素含量以及抗营养物质的营养概况。转基因水稻和非转基因水稻均在两个不同地点种植和收获。Agb0103水稻的水分、淀粉、蛋白质、脂质和灰分含量等近似成分与亲本非转基因水稻相似。除了少数营养成分存在微小的产地差异外，转基因水稻和非转基因水稻在整体营养成分方面没有差异。具有改良抗旱性的Agb0103水稻在营养上与亲本水稻品种相当。
