Polyadenylation and characterizations of lncRNAs. a Poly(A) + and poly(A)– proportions of TAIR10 and novel lncRNAs. There were 1115 lncRNAs (accounting for over 70 %) classified as poly(A) + lncRNAs, and 112 classified as poly(A)– lncRNAs. bd Comparison of poly(A) + and poly(A)– lncRNAs using exon number, expression level, and conservation. The lncRNAs exhibited lower exon number and conservation than protein-coding transcripts. Poly(A)– lncRNAs showed lower expression levels than poly(A) + lncRNAs. e Validation of poly(A) + and poly(A)– lncRNAs using qRT-PCR. Poly(A) + lncRNAs were much more abundant in poly(A) + than poly(A)– samples; whereas, poly(A)– lncRNAs were mainly expressed in poly(A)– samples
