摘要: 长链非编码RNA(Long non-coding RNA,lncRNA)长度大于200个核苷酸,大量存在于生物体中并具有多种生物学功能。目前,植物中发现的lncRNA大多由RNA聚合酶Ⅱ转录,并通过目标模仿、转录干扰、组蛋白甲基化和DNA甲基化等多种机制介导基因的表达,在植物开花、雄性不育、营养代谢、生物和非生物胁迫等生物过程中起着调节因子的作用。文章综述了近年来发现的植物lncRNA数据库、预测方法、表达及可能的生物学功能。

Abstract: Long non-coding RNAs (lncRNAs), which are longer than 200 nucleotides in length, widely exist in organisms and function in a variety of biological processes. Currently, most of lncRNAs found in plants are transcribed by RNA polymerase Ⅱ and mediate gene expression through multiple mechanisms, such as target mimicry, transcription interference, histone methylation and DNA methylation, and play important roles in flowering, male sterility, nutrition metabolism, biotic and abiotic stress and other biological processes as regulators in plants. In this review, we summarize the databases, prediction methods, and possible functions of plant lncRNAs discovered in recent years.
