摘要: 转基因大豆种植后其外源基因表达产物会以叶片残体等形式暴露于土壤生态系统中,并对土壤动物存在潜在风险.本文利用我国自主研制的转hrpZm基因抗疫霉根腐病大豆B4J8049、转Cry1C基因抗食叶性害虫大豆A2A8001、转Cry1Iem基因抗食心虫大豆C802及非转基因对照亲本大豆Williams82,采用直接喂饲试验,通过60 d喂饲调查白符跳的存活率、繁殖率、体长变化等,研究3种转基因大豆材料对非靶标生物白符跳的影响.结果表明: 转基因大豆B4J8049、A2A8001和C802残体对环境指示生物白符跳的存活率、繁殖率及生长发育均无显著不良影响.初步确认转基因大豆B4J8049、A2A8001和C802在短时期内对环境无安全性风险,为其推广提供了生态安全基础数据.

Abstract: When the genetically modified soybean is planted in the field, the expression product of exogenous gene could be exposed in the soil ecosystem and bring potential risk to the soil fauna, with the form of leaves and other debris. A few of genetically modified soybeans developed by China independently were used in our study as materials. They were Phytophthora-resistant soybean harboring hrpZm gene (B4J8049), leaf-feeding insect-resistant soybean harboring Cry1C gene (A2A8001) and Leguminivora glycinivorella-resistant soybean harboring Cry1Iem gene (C802). By feeding Folsomia candida with the three genetically modified soybeans for continuous 60 days, the surviving rate, reproductive rate and changes on the body length of F. candida were studied. The results showed that all the three genetically modified soybeans of B4J8049, A2A8001 and C802 had no significant adverse effects on the growth of F. candida, as an environmental indicator organism. It was initially inferred that they were environmentally safe under short-term exposure, which provided basic data of ecological safety for their wide cultivation.
