水稻和玉米是我国重要的粮食作物，既是主食，又是饲料和工业原料。多种因素制约着这两种作物的生产，其中虫害是一个重要因素。鳞翅目害虫每年给农作物造成巨大的产量损失。为了控制这些害虫，中国在作物基因工程（GE）的开发和应用方面发挥了积极作用，已经开发出数十种表达来自土壤细菌苏云金芽孢杆菌（Bt）杀虫蛋白的GE水稻和GE玉米品系。已有多个品系进入环境释放、田间试验和生产前试验阶段，室内和田间试验表明，我国育成的Bt水稻和Bt玉米品系大多对水稻二化螟、三化螟和稻纵卷叶螟等主要鳞翅目害虫有较好的防治效果，具有广阔的应用前景。然而，到2016年为止，这些Bt品系还没有商业化种植。讨论了我国转Bt基因水稻和玉米开发应用面临的挑战和前景。本文介绍了我国Bt作物的研究和开发概况，并对今后的研究工作提出了建议。
Rice and maize are important cereal crops that serve as staple foods, feed, and industrial material in China. Multiple factors constrain the production of both crops, among which insect pests are an important one. Lepidopteran pests cause enormous yield losses for the crops annually. In order to control these pests, China plays an active role in development and application of genetic engineering (GE) to crops, and dozens of GE rice and GE maize lines expressing insecticidal proteins from the soil bacterium Bacillus thuringiensis (Bt) have been developed. Many lines have entered environmental release, field testing, and preproduction testing, and laboratory and field experiments have shown that most of the Bt rice and Bt maize lines developed in China exhibited effective control of major target lepidopteran pests on rice (Chilo suppressalis, Scirpophaga incertulas, and Cnaphalocrocis medinalis) and maize (Ostrinia furnacalis), demonstrating bright prospects for application. However, none of these Bt lines has yet been commercially planted through this writing in 2016. Challenges and perspectives for development and application of Bt rice and maize in China are discussed. This article provides a general context for colleagues to learn about research and development of Bt crops in China, and may shed light on future work in this field.
