The soybean product MON 87701 × MON 89788 expresses both the cry1Ac gene derived from Bacillus thuringiensis and the cp4 epsps (5-enolpyruvylshikimate-3-phosphate synthase) gene derived from Agrobacterium sp. strain CP4. Each biotechnology-derived trait confers specific benefits of insect resistance and glyphosate tolerance, respectively. The purpose of this study was to compare the composition of seed and forage from this combined-trait product to those of conventional soybean grown in geographically and climatically distinct regions. Field trials were conducted in the United States during the 2007 growing season, in Argentina during the 2007-2008 growing season, and in the northern and southern soybean regions of Brazil during the 2007-2008 and 2008-2009 growing seasons. Results demonstrated that the compositional equivalence of MON 87701 × MON 89788 to the conventional soybean extended across all regions and growing seasons. Further evaluation of the data showed that natural variation (region and growing season) contributed more to compositional variability in soybean, particularly for such components as isoflavones, fatty acids, and vitamin E, than transgene insertion.
MON 87701×MON 89788 大豆产品表达了来自苏云金芽孢杆菌的 cry1Ac 基因和来自土壤农杆菌 CP4 菌株的 cp4 epsps（5-烯醇丙酮酰莽草酸-3-磷酸合酶）基因。每种生物技术衍生的特性分别赋予了抗虫性和草甘膦耐受性的特定益处。本研究的目的是比较这种组合特性产品的种子和饲料与在地理位置和气候上不同的地区种植的常规大豆的成分。田间试验于 2007 年在美国进行，于 2007-2008 年在阿根廷进行，于 2007-2008 年和 2008-2009 年在巴西的北部和南部大豆种植区进行。结果表明，MON 87701×MON 89788 与常规大豆的成分等效性扩展到所有地区和生长季节。对数据的进一步评估表明，自然变异（地区和生长季节）对大豆的成分变异性的贡献大于转基因插入，特别是对于异黄酮、脂肪酸和维生素 E 等成分。
