Abstract：Glyphosate is the dominant herbicide worldwide. Herbicide tolerance is the most important agronomic traits of biotech crops. This article briefly stated the mechanism of action of glyphosate and its tolerant gene, and introduced the current status of excavation the glyphosate-tolerant gene and the relative patents in China. Until the end of 2012, there are 15 patent applications of domestic units and individuals in glyphosate-resistant have been patented in China, and another 22 applications are under review. It is clearly that the domestic exploring new glyphosate-tolerant gene and getting the independent intellectual property made great strides since 2007. By the authentication glyphosate resistance in transgenic plants, some resistance genes have appeared the potential value of commercial applications.
