来自转基因玉米植株中的杀虫毒素可以渗入到土壤中 ,并可持续存留数周。这是纽约大学研究人员发现的 ,随之而来的问题是对土壤生态学的冲击。试验材料是在室内种植的转基因Ｂｔ玉米植株。该玉米可免受钻心虫的危害。此种玉米根系周围土壤提取物中仍含有Ｂｔ毒素 ,并同样可以杀
Pesticidal toxins from transgenic corn plants can penetrate the soil and persist for weeks. This is what New York University researchers discovered, and the ensuing problem is the impact on soil ecology. The test material is a transgenic Bt corn plant grown indoors. The corn is free from diamond worms. The Bt toxin is still contained in the soil extract around the roots of this corn and can be killed as well
