A new method of RNAi vector construction and its application of secondary metabolism regulation of plants / 中草药

ABSTRACT

RNA interference (RNAi) technology has strong specificity, high inhibitory efficiency, large-scale operation application, and good repeatability, and it can perform Mendelian mode of inheritance in plants, which is widely used in the validation of gene function and metabolic regulation. In plant metabolic engineering, the RNAi method can inhibit the synthesis of product, change the distribution of metabolic flux, and regulate the synthesis of the target product. This review summarized the current progress and study strategy of RNAi in plant metabolic regulation. RNAi mechanism and characteristics, optimal strategy of vector structure, efficient RNAi vector construction method, and application progress in the regulation of metabolism were reviewed, in order to lay the theoretical foundation and technical reference of RNAi technology of metabolic engineering control.
