植物长链非编码RNA研究进展

Advances in Research of Plant Long Non -coding RNAs

长链非编码RNA（lncRNA）被定义为长度大于200nt，没有明显编码潜力的RNA。lncRNA已经在各种生物调节过程中发挥重要作用，并且以比mRNA更多的组织特异性方式表达。在植物中，虽然大量的lncRNA转录物已在少数物种中预测和鉴定，但我们目前对其生物功能的了解仍然有限。本文将主要从lncRNA在植物中对生物和非生物胁迫的作用进行总结，并简要介绍近些年来建立的与lncRNA相关的数据库。

Long non -coding RNA （lncRNA） is defined as RNA with a length greater icant coding than 200 nt and no signifpotential, lncRNAs have played an important role in various biological regulation processes and are expressed in a more tissue - specific manner than mRNA. In plants, although a large number of lncRNA transcripts have been predicted and identified in a few species, our current understanding of their biological function is still limited. This article will summarize the role of lncRNAs in biotic and abiotic stresses in plants, and briefly describe the lncRNA- related databases established in recent years.
