摘要
总结了转基因棉花在生态安全性方面的研究进展,重点介绍了转基因棉花对土壤生态环境的影响,包括:外源基因表达产物在土壤中的富集;外源基因表达产物对土壤生物的影响;外源基因在土壤生态系统中的水平转移。认为目前对转基因棉花的土壤生态学过程的研究较少,尚难以确定转基因棉花对土壤生态环境的影响程度。并由此介绍了Biolog系统和DNA指纹技术在土壤生态安全性研究中的应用。
Ecosafety of transgenic cotton is reviewed in the paper with emphasis on its influence on soil ecosystem, including enrichment of transgenes in soil, effects of transgenes on soil biology, and horizontal transfer of transgenes in soil ecosystem. It is held that since so far not much research has been done on soil ecology of transgenic cotton, it is now hard to determine how much transgenic cottons would affect soil eco-environment. In addition, a brief introduction is given to the application of the Biolog-system and DNA-fingerprints technology to the research on soil ecological safety and safety evaluation of transgenic cotton.
