中文摘要：

With the development of genomics and bioinformatics, especially the extensive applications of high-throughput sequencing technology, more transcriptional units with little or no protein-coding potential have been discovered. Such RNA molecules are called nonprotein-coding RNAs(npc RNAs or nc RNAs). Among them, long npc RNAs or nc RNAs(lnpc RNAs or lnc RNAs) represent diverse classes of transcripts longer than 200 nucleotides. In recent years, the lnc RNAs have been considered as important regulators in many essential biological processes. In plants, although a large number of lnc RNA transcripts have been predicted and identified in few species, our current knowledge of their biological functions is still limited.Here, we have summarized recent studies on their identification, characteristics, classification,bioinformatics, resources, and current exploration of their biological functions in plants.
