摘要/Abstract

摘要： MicroRNA(miRNA)是一类小分子非编码RNA,通过降解靶基因途径在转录后水平调控基因表达,参与植物生长、发育以及逆境胁迫应答等多种细胞代谢活动。种子是植物生长的基础要素,是农业生产的重要资料。与种子发育相关的miRNA已在多种植物中得到鉴定。文章综述了参与植物种子发育过程的miRNA及其在种子发育中的具体调控机制,旨在为利用miRNA提高种子遗传特性提供研究思路。

关键词: 种子, miRNA, 发育, 调控机制, 植物

Abstract: MicroRNA (miRNA), a class of non-coding small RNAs, has been reported to be involved in a broad range of metabolic and physiological processes in plants, such as plant growth, development and responses to stresses. They participate in gene expression by degrading target genes at post-transcriptional levels. Seeds are the basic elements of plant growth and important materials for agriculture. miRNAs have been identified to be involved in seed development in many plants. Herein we review recent progresses on the miRNAs involved in seed development and their regulatory mechanisms, which will help to provide insights into further research to improve seed quality.

Key words: seed, miRNA, development, regulatory mechanism, plant
