摘  要：
长非编码RNA(long non-coding RNA,lnc RNA)是真核生物中广泛存在的一类转录本超过200 nt不编码蛋白质的RNA,参与干细胞维持、胚胎发育、细胞分化、细胞生长、细胞凋亡、代谢、信号传导以及免疫应答等生理或病理过程的调控。本研究结合植物基因组特点以及高通量RNA测序数据,采用生物信息学手段建立并优化了一套植物lnc RNA筛选和鉴定的方法。利用此方法在胡杨异形叶发生的138 845个RNA-Seq测序数据中,筛选并鉴定了2 448个参与胡杨异形叶发生的lnc RNA,并进一步对其功能进行预测和分析,为研究胡杨异形叶生长发育特性及最终揭示叶形发育的分子机制提供资料和理论帮助。

摘  要：
Long non-coding RNA(lnc RNA), widely existing in eukaryote, is a RNA of non-coding proteins with over 200 nt transcripts. lnc RNA participates in some regulation of physiological or pathological processes, such as stem cells, embryonic development, cell differentiation, cell growth, cell apoptosis, metabolism, signal transduction and immune response etc. In this study, according to the characteristics of plant genome and high-throughput sequencing datas, a method to screen and identify lnc RNAs in plant was established and optimized by means of bioinformatics. Utilizing this method, 2 448 lnc RNAs associated with leaf shape development were screened and identified from 138 845 RNA-Seq datas of P. euphratica heterophyll, and their functions were further analyzed. The feasible method can take a help for discovery and identification of lnc RNAs from high-throughput sequencing data, and favor finally revealing the molecular mechanism of leaves morphogenesis.
