WRI1调控植物油脂合成的研究进展

Progress on WRI1 regulation of plant oil biosynthesis

油脂是植物主要的储能物质,也是植物质膜的重要组分,同时还参与植物信号传导、气孔开闭、授粉受精、种子萌发、胁迫响应等多个生物学过程。WRINKLED 1(WRI1)是AP2转录因子家族的成员,在油脂合成过程中起重要调控作用。本文综述了近年来WRI1在植物油脂合成中的研究进展,主要包括(1)WRI1的发现、起源和进化特征;(2)WRI1的基因表达特征、基因结构、蛋白质结构和启动子顺式作用元件;(3)WRI1的转录水平和翻译水平调控机制以及下游的靶基因;(4)对WRI1后续的研究思路和应用前景进行展望。本综述内容以期为深入了解WRI1调控植物油脂合成的分子机制提供参考,也为利用WRI1改良油料作物提供理论基础。

Oil is the main energy storage substance and an important membrane component of plant.Oil is also involved in the signal transduction,stomatal opening and closing,pollination and fertilization,seed germination,and stress response.WRINKLED 1(WRI1),a member of the AP2 transcription factor family,is master regulator in transcriptional control of plant oil biosynthesis.This paper reviewed recent advances in regulatory mechanism of WRI1 on plant oil biosynthesis,including(1)the discovery,origin,and evolutionary characteristics of WRI1;(2)gene expression characteristics,gene structure,protein structure,and promoter cis-acting elements of WRI1;(3)regulation mechanism of transcription level and translation level,and downstream target genes of WRI1;(4)the future research direction and application prospects.This review is expected to provide a reference for further understanding the molecular mechanism of WRI1 regulating plant oil synthesis,and also provide a theoretical basis for improving oil crops with WRI1.
