Abstract:

Glyphosate is a broad-spectrum, inner-absorption conducting herbicide that has been widely used in maize production. With development of plant genetic engineering technology and continuously expansion of genetically modified crops planting area, the research and development of glyphosate-resistant transgenic maize have become an important part of maize breeding. In this paper, we introduced the function mechanism of glyphosate, analyzed in detail the strategy of glyphosate-resistant plant genetic engineering. The paper also systematically reviewed the internal and external progress made in research and development of glyphosate-resistant transgenic maize, and its commercial application. It put forward strategy for studying and developing glyphosate-resistant transgenic maize in China, so as to provide relevant references for enhancing glyphosate-resistant transgenic maize research in China.

Key words: glyphosate, genetic transformation, transgenic breeding, commercialization

摘要：

草甘膦是广谱灭生性、内吸传导型除草剂,广泛应用于玉米生产,随着植物基因工程技术的发展以及全球转 基因作物种植面积的不断增加,抗草甘膦转基因玉米研发已成为玉米育种的重要内容。介绍了草甘膦的作 用机理,详细分析了抗草甘膦转基因植物基因工程策略。较为系统地分析了当前国内外抗草甘膦转基因玉 米研发及商品化应用进展,进而提出了针对我国抗草甘膦转基因玉米研发的策略。以期为我国抗草甘膦转 基因玉米研究提供参考。
