摘要/Abstract

摘要：

植物microRNA(miRNA)是一类小分子非编码RNA,对植物的生长发育发挥着重要调控作用。种子发育、休眠与萌发是植物生命进程中的重要阶段。在这一阶段内,种子受各种环境因子及内源激素调控,并且不同植物种子具有不同发育及休眠特性。随着人们对种子发育、休眠及萌发机理的探究,越来越多miRNA被鉴定,它们能够基于植物激素信号传导、抗氧化作用、关键转录因子调控等途径参与种子形态建成、物质代谢及各种胁迫响应。本文主要综述了近年来植物miRNA的形成及调控机理,以及在种子发育、休眠及萌发过程中发挥的调控作用,旨在为今后的研究方向提供参考。

Abstract:

In plants, microRNAs (miRNAs) are a class of non-coding small RNAs that play important roles in various biological processes, such as seed development, dormancy and germination. In these stages, seeds are regulated by various extrinsic environmental factors and intrinsic hormones. Different species of seeds have distinct development and dormancy characteristics. Recent investigations have identified more and more miRNAs to regulate seed morphogenesis, material metabolism and stress response capacities through hormonal signal transduction, antioxidant effects and transcription factors, etc. In this review, we summarize recent progresses on regulatory mechanisms of miRNAs, and also complex multilevel regulation of miRNAs in the process of seed development, dormancy and germination. We hope to provide insights into further research.

Key words: seed, development, dormancy, germination, miRNA
