| 摘 要： | 随着转基因作物商品化应用的增多，对其进行生态风险性评价尤为重要.国内外对转基因作物中外源基因向野生亲缘物种漂移的可能性、昆虫对抗虫转基因作物的耐受性以及转基因作物对生物多样性的潜在影响等问题进行了广泛的研究.文中从Bt杀虫结晶蛋白在土壤中的残留特性、Bt杀虫晶体蛋白对土壤微生物可培养类群和土壤酶活性的影响等方面对转Bt基因抗虫水稻的潜在生态风险性进行了简要综述，以期为同类研究提供有益的信息.

| Abstract: | With the increasing commercial use of genetically modified crops (GMCs),it is quite important to assess their potential ecological risk.The likelihood of genes dispersal from GMCs to related wild species,the tolerance of insects to insect-resistant GMCs,and the potential impact of GMCs on biodiversity have been extensively investigated.This article reviewed the potential ecological risk assessment of transgenic Bt rice-expressed products,including the persistence characteristics of Bt insecticidal crystal proteins in soil,and their effects on soil culturable microbial flora and soil enzyme activities,which could provide useful information for related researches. |
