中文摘要:T1C-19是新开发的有效抵抗鳞翅目害虫的转基因水稻,其由玉米泛素启动子驱动来表达cry1C基因。褐飞虱是水稻主要非靶标害虫之一,青翅蚁形隐翅虫是褐飞虱的捕食者。青翅蚁形隐翅虫可通过捕食褐飞虱而获得Cry1C蛋白,这在评估转cry1C基因水稻对捕食者的潜在影响中至关重要。本文通过两个实验,来进行转Cry1C基因水稻对青翅蚁形隐翅虫生态风险评估研究。研究发现,在两组试验中青翅蚁形隐翅虫的生长发育、存活量、雌虫比例和体重没有显着的负面影响。研究结果表明,转Cry1C基因水稻对青翅蚁形隐翅虫没有有害的影响。本文用青翅蚁形隐翅虫作为指示物种来评估转基因作物对非靶标节肢动物的潜在影响是可行的。
外文摘要:T1C-19 is newly developed transgenic rice active against lepidopteran pests, and expresses a synthesized cry1C gene driven by the maize ubiquitin promoter. The brown planthopper, Nilaparvata lugens, is a major non-target pest of rice, and the rove beetle (Paederus fuscipes) is a generalist predator of N. lugens nymphs. As P. fuscipes may be exposed to the Cry1C protein through preying on N. lugens, it is essential to assess the potential effects of transgenic cry1C rice on this predator. In this study, two experiments (a direct feeding experiment and a tritrophic experiment) were conducted to evaluate the ecological risk of cry1C rice to P. fuscipes. No significant negative effects were observed in the development, survival, female ratio and body weight of P. fuscipes in both treatments of direct exposure to elevated doses of Cry1C protein and prey-mediated exposure to realistic doses of the protein. This indicated that cry1C rice had no detrimental effects on P. fuscipes. This work represents the first study of an assessment continuum for the effects of transgenic cry1C rice on P. fuscipes. Use of the rove beetle as an indicator species to assess potential effects of genetically modified crops on nontarget arthropods is feasible.
