摘要:

植物基因的表达决定了植物的表型特征,而基因的表达受启动子的直接调控。启动子作为基因的一个组成部分,控制着基因表达(转录)的起始时间和表达程度。利用基因编辑技术对启动子进行定向编辑之后,会因为基因序列特有的重组排列、顺式表达等因素使得植物中的某个或某些基因的表达模式发生改变,进而影响基因功能。这些改变最终直接或间接地改变了植物的外在表型特征,而一些正向改变会对植物的品质起到优化和改良作用。综合近几年基因编辑技术对启动子的研究,主要从启动子的构成与分类、基因编辑技术和启动子编辑的研究进展这3个方面对启动子的编辑在植物中的应用进行了概述和总结,以期为启动子编辑技术应用于植物改良提供参考。

Abstract:

Plant gene expression determines plant phenotypic characteristics, and gene expression is directly regulated by promoters. As a component of genes, promoters control the initiation time and expression degree of gene expression (transcription). After directed editing of promoters by gene editing technology, the expression pattern of one or some genes in plants would be changed due to the unique recombination and arrangement of gene sequences, cis-expression and other factors, thus affecting the function of genes. These changes ultimately directly or indirectly change the external phenotypic characteristics of plants, and positive changes would help to optimize and improve plant quality. In this paper, the application of promoter editing in plants was summarized from three aspects: the structure and classification of promoters, gene editing technology and the research progress of promoter editing, which was expected to provide reference for plant improving by promoter editing.

Key words: gene editing technology, promoter editing, plant quality improvement
