Annotation of lncRNAs in Arabidopsis. LncRNAs are classified into two categories based on their genomic locations: NAT-lncRNAs and lincRNAs. NAT-lncRNAs include overlapping NAT-lncRNAs and non-overlapping NAT-lncRNAs. Non-coding and coding transcripts are depicted as gray and black bars, respectively. Arrows indicate the directions of transcription
