Application of Agrobacterium-mediated Transformation in Rice Genetic Engineering

With the development of biotechnology, rice genetic engineering is playing more and more important role in rice breeding. There are many methods for foreign genes transformation in plants. Among these methods, the transformation system mediated by Agrobacterium has aroused much attention because of its special advantages. In this paper, we introduced the principles and advantages of Agrobacterium-mediated transformation. At the same time we also introduced the influence on rice transformation mediated by Agrobacterium with the difference of Agrobacterium tumefaciens, transgenic acceptors and medium concentration. In addition, we summarized the progress on the application of this transformation system in insect-resistance genetic engineering of rice, disease-resistance genetic engineering of rice, stress-resistance genetic engineering of rice, good quality genetic engineering of rice, herbicide-resistance genetic engineering of rice, improving photosynthesis rates and delaying age of rice. Finally, we explained the problems in application of Agrobacterium-mediated transformation in rice genetic engineering briefly and discussed its prospect.
