摘要: 转座子是基因组的重要组分, 影响基因组的结构与稳定。长链非编码RNA (lncRNA)在转录及转录后水平调控多个生物学过程。转座子与lncRNA是物种进化的重要驱动力。含有转座子序列的lncRNA在自然界广泛存在。该文对植物lncRNA的发掘策略和功能研究进行概述, 围绕植物转座子来源lncRNA (TE-lncRNA)的分布和功能展开综述, 并对植物TE-lncRNA的调控机制、表观修饰及育种潜势等进行探讨与展望。

Abstract: Transposable element (TE), core component of the genome, influences genome structure and stability. Long noncoding RNA (lncRNA) modulates diverse biological events at transcriptional and post-transcriptional levels. TE and lncRNA are major driving forces of evolution. Emerging evidence has revealed the wide distribution of lncRNA that harbors TE. In this review, we first briefly introduce the methodologies of identification and functional analysis of plant lncRNA. We focus on the distribution and function of transposable element-derived lncRNA (TE-lncRNA). Finally, we discuss the regulatory mechanism, epigenetic modification, and breeding potential of TE-lncRNA in plants.

Key words: transposable element, long noncoding RNA, transposon-derived lncRNA, plant
