Research Progress in Genetic Transformation and Regeneration System of Soybean

As one of modern biotechnologies, transgenic technology has made important progress in gene function research and transgenic breeding. Soybean functional genomics has developed rapidly since the completion of soybean genome sequencing, and it has attracted wide attentions to excavate genes controlling important characters for transgenic breeding. With the implementation of the major project of new varieties cultivation of genetically modified soybean, China has established the research technology system and supervision system of transgenic breeding including gene cloning, genetic transformation, functional research, safety evaluation of transgenic lines and etc. Among them, the research on technology system of genetic transformation for transgenic soybean has made rapid progress, which was mainly focused on the establishment and optimization of stable and efficient regeneration system of genetic transformation, exploration and optimization of soybean genetic transformation methods and etc. The purpose of this paper is to elaborate the following aspects including genetic transformation system, transgenic methods and transformation efficiency of soybean and to provide reference for the researches on gene functions and the cultivation of genetically modified soybean.
