Long noncoding RNAs (lncRNAs) are increasingly recognized as functional regulatory components in eukaryotic gene regulation. Distinct classes of lncRNAs have been identified in eukaryotes and they play roles in various regulatory networks. Previously characterized lncRNAs include primary transcripts for small regulatory RNAs. In the era of deep sequencing, new classes of lncRNAs have emerged as potent regulatory components in gene regulation. Recent studies showed that many lncRNAs are potent cis- and trans-regulators of gene activity and they can function as scaffolds for chromatin-modifying complexes. Furthermore, differential expressions of lncRNAs suggest that transcription of lncRNAs can modulate gene activity during development and in response to external stimuli. Here, we summarize our current understanding on potential roles of lncRNAs in plants.
