摘　要：摘　要：植物长链非编码RNA(long noncoding RNA， lncRNA) 是调节植物生长发育的一类分布广泛和种类丰富，且作用机制多样的非编码RNA。虽然植物lncRNA 还处于研究的起步阶段，很多相关信息还不清楚，但近期的研究显示，它们在植物的发育，尤其是生殖发育中具有重要功能。植物的生殖发育不仅是植物生长中最重要的环节之一，也是作物育种中最关键的步骤，因此，发掘植物生殖发育相关的lncRNA 具有重要的意义。现总结了已有的植物lncRNA 的鉴定和特征分析，着重介绍调节植物开花和有性生殖相关的lncRNA 及功能，以及lncRNA 是通过何种作用方式参与到植物生殖调控中的。

Abstract: Abstract: Plant long noncoding RNAs (lncRNAs) play important roles in a wide range of biological processes through various mechanisms. Although the lncRNAs related researches are limited， recent progresses have shown that lncRNAs are crucial in regulating plant development especially in regulating reproductive growth. Plant reproductive growth is one of the most fundamental development processes， and is the critical step in crop breeding， thus it is important to explore reproductive development related lncRNAs in plants. In this review， we summarized the current knowledge of lncRNAs discoveries in plants including their feature analysis， with an emphasizing on the plant flowering and sexual reproduction related lncRNAs and the regulatory mechanisms by which lncRNAs regulating plant reproduction.
