基因修饰(GM)作物常被用来增加食物产量,如抗虫抗除草剂作物已商业化或接近市场化。在许多情况下,用细菌基因转换的GM作物转位基因的特有蛋白表达水平是很低的,接近宿主作物总蛋白的0.01%-0.1%。这些GM作物的安全是用科学概念“实质等同性”来评估的。“实质等同性”是1993年由经济合作 Genetically modified (GM) crops are often used to increase food production, as insect-resistant and herbicide-resistant crops are already commercially available or near market-based. In many cases, peculiar protein expression levels of bacterial transposable GM crop transposable genes are very low, approaching 0.01% -0.1% of the total protein in the host crop. The safety of these GM crops is assessed using the scientific concept of “substantial equivalence.” “Substantive equivalence” was established in 1993 by economic cooperation
