植物长链非编码RNA的研究进展

The Research Progress of Long Non-coding RNA in Plants

长链非编码RNA(long non-coding RNAs,lnc RNAs)是真核生物中一类长度大于200个核苷酸、无蛋白编码能力或编码能力极低的RNA转录本。lnc RNA种类和功能的多样性导致了对其进行研究的复杂性,特别是对植物中lnc RNA的认识相当有限。该文就近年来植物中已发现的lnc RNA的种类、相关转录酶、参与的生物学过程、发挥功能的分子机制以及其相关的研究策略等方面进行综述和展望,以期为深入认识植物lnc RNA提供借鉴。

Long non-coding RNAs（lnc RNAs）, widely found in eukaryotes, are tentatively defined as a class of RNA transcripts, which are greater than 200 nt in length and have extremely low protein-coding ability or without protein-coding ability. The type and function diversity of lnc RNAs make them difficult to be understood. Especially, the knowledge about lnc RNAs in plants is still quite limited. In this review, the types of characterized lnc RNAs, the RNA polymerases involved in lnc RNAs transcription, the associated biological functions and the corresponding molecular mechanisms, as well as the methods and strategies for lnc RNAs research were introduced and discussed.
