| 摘 要： | 综述了转Bt基因作物的Bt毒素在土壤中的环境去向及其生态效应的研究进展。重点阐述了：①Bt毒素与土壤表面活性颗粒结合及其与土壤理化性质的关系；②Bt毒素微生物利用与降解；③Bt毒素的杀虫活性；④后茬作物和土壤动物对Bt毒素的吸收与利用；⑤Bt毒素的垂直运移；⑥Bt毒素对土壤生物和生态过程的影响。转Bt基因作物的Bt毒素对土壤生态系统的影响急需在生态系统水平进行深入细致的长期定位研究。

| Abstract: | There is controversy about the means of environmental risk assessment and management of transgenic crops because of the speed and quantity of these cr ops being planted, particularly those containing genes to produce the insecticid al toxin from Bacillus thuringiensis (Bt). Most research on Bt crops has foc used on invasiveness, gene flow to indigenous organisms, development of resistance i n target pests, and direct or indirect effects on non-target organisms and ecos y stems. However, after the commerci... |
