摘要/Abstract

摘要： 水稻是世界主要的粮食作物之一,同时也是重要的饲料原料.近年来国内外研究机构培育出数种转苏云金芽孢杆菌(Bacillus thuringiensis,Bt)基因水稻,可有效杀灭二化螟、三化螟、稻纵卷叶螟等虫害,减少水稻种植过程中农药的使用,提高水稻产量.由于水稻是人类主要的粮食作物,转Bt基因水稻的安全性受到广泛的关注.截至目前尚未有确切证据证实转基因水稻存在饲用安全性问题,但仍需对其长期饲用结果进行持续监控.作者现就转Bt基因水稻的发展、潜在风险和安全评价方法,营养价值、毒理性,对动物生长、免疫、肠道微生物的影响,以及外源基因和外源蛋白的残留等方面进行简要综述.

Abstract: Rice is one of the major food crops for humans.It is also an important feed source of animals.In recent years,several transgenic Bacillus thuringiensis (Bt) rice were bred by domestic and international research institutes.These varieties of transgenic Bt rice can kill insect pests such as rice stem borer,yellow rice borer and rice leaf roller.They can also reduce the use of pesticides and boost rice yields.People pay much attention to safety of transgenic Bt rice as it is one of the major food crops.As yet there is no definite evidence that the transgenic Bt rice has safety issues.But we still need to monitor the results of long-term consumption of the rice continuously.This article mainly reviews the development,potential risk and safety assessment method,nutritional value and toxicity of transgenic Bt rice,the impact of growth and immune of animals,the foreign gene and the foreign protein in vivo residual.

Key words: transgenic Bt rice; nutritional value; growth; immune; foreign gene; residual
