摘要:

顺式调控元件是具有调控功能的非编码DNA序列,确保植物在不同生长发育阶段和环境应答时相关基因正确的时空表达。目前,植物顺式调控元件的功能研究落后于动物,然而依托较完善的基因组注释信息和开放染色质技术,植物顺式调控元件研究取得了重要进展。文章综述了植物顺式调控元件的相关研究,发现活性顺式调控元件与染色质活性相关联,转录因子和顺式调控元件之间的相互作用决定了基因转录水平,高通量测序技术提供的不同分子层面的组学数据能高效鉴定到顺式调控元件,由转座子衍生的顺式调控元件调控农艺性状基因转录。精准鉴定和深入功能解析顺式调控元件是未来重要的研究方向。植物顺式调控元件的挖掘与功能解析有助于系统阐明农作物重要农艺性状基因的调控机制,更好助力于培育高产、优质、高抗、高效的优良新品种。

Abstract:

Cis-regulatory elements are non-coding DNA sequences serving the key regulatory function, which ensure the proper spatiotemporal patterns of gene expression necessary for responses to development and environmental cues. Currently, the functional study of cis-regulatory elements in plants lags behind that of animals. However, relying on the improvement of genome annotation and open chromatin profiling methods in plants, great progress has been made in the research of plant cis-regulatory elements. This paper summarizes the latest research findings of plant cis-regulatory elements: active cis-regulatory elements correlate with chromatin activity, the interactions between transcription factors and cis-regulatory elements determine the level of gene transcription, the high-throughput sequencing technology provides omics data at different molecular levels to efficiently identify cis-regulatory elements, cis-regulatory elements derived from transposons regulate the transcription of agronomic trait genes. Accurate identification and in-depth functional analysis of cis-regulatory elements are important research directions in the future. The exploration and functional analysis of plant cis-regulatory elements are helpful to systematically elucidate the regulatory mechanism of important agronomic traits genes in crops, thereby better facilitating the cultivation of new varieties that are high-yield, high-quality, highly-resistance and high efficiency.

Key words: cis-regulatory element, open chromatin, transcription factor, chromatin activity
