| Abstract: | Gene targeting is one of the important tools in reversed genetics and a powerful tool in functional characterization of plant genes.Positive-negative selection system is used to identify correct transformants upon gene targeting.Using selection systems can reduce work load and greatly improve gene targeting efficiency.In recent years,with continuous studies and improvement,the use of positive-negative selection in plant gene targeting has become normal.This paper expounds the principle of the method and sum... |
