Gene expression is one of the major applications in plant molecular biology, which plays important role in theoretical and agricultural application researches. Due to the weak foundation and lack of tools, most of the early studies used constitutive promoters, such as the most commonly used 35S promoter of cauliflower mosaic virus, to overexpress. With the further researches, people have more understanding of the molecular biology of gene expression, and then derived better and more tools. In order to have spatiotemporal and quantitative fine-tune expression, several inducible gene expression systems have been developed. Classified according to different inducers, the commonly used expression systems are as such, the tetracycline induced, the steroid induced, the ethanol induced, the insecticide induced, and the copper induced. These systems have different working principles because of the different factors and components used; at the same time, there are also commonalities in each of them, they are usually composed of two elements, the activation element and the response element. In this paper, several plant inducible expression systems are reviewed, and their characteristics are analyzed, reviewed and prospected.
