转Bt基因水稻安全性评价研究进展

Advances on the Safety Researches of Transgenic Bt Rice

转基因技术的发展为利用外源基因培育优良品种提供了新的途径,目前国内外已培育出多个高抗水稻害虫的转基因水稻材料,并获准进入中间试验和环境释放。但是,人们对转基因抗虫水稻潜在的风险尚存在疑问,这是目前转基因水稻未能进一步获准商品化生产的一个重要原因。简要综述了近年来国内外转Bt基因水稻研究现状与安全性评价的最新进展,主要涉及食品安全性、环境生态安全性及昆虫对其产生抗性,并对将来的工作提出几点建议。

The development of transgenic technology provides a new path to breed new varieties with exogenous genes, now many transgenic rice materials resistant to pests have been bred around the world, and some have been approved into median experiment and environment release. However, peoples are worry about the potential risks of the transgenic rice, and this is an important reason that transgenic rice cann't be approved to be commercialized. The recent advances on safety of transgenic Bt rice around the world are reviewed, and it includes food safety, ecological safety, resistance of pests to transgenic Bt rice and etc.
