美国研究人员称,他们首次发现转基因作物产生的杀虫用毒素可由根部渗入周围土壤。但他们同时强调说.这一发现是实验室中获得的,转基因作物毒素渗入土壤后对自然环境将产生何种影响需作进一步的田间研究才能得出结论。纽约大学生物系的科学家们介绍说,他们在 US researchers say they first discovered that insecticidal toxins produced by genetically modified crops can penetrate the surrounding soil from the roots. However, they also stressed that this finding was obtained in the laboratory and that the effects of the transgene toxin into the soil after the soil penetrated into the soil required further field studies to be concluded. Scientists at New York University’s Department of Biology said they are there
