Comparisons of transcript length, exon number and ORF length. (a) Comparison of transcript length. The novel lncRNAs show shorter length (∼1.2kb) on average than either RefSeq protein-coding (∼3.1kb) or non-coding transcripts (∼1.9kb); (b) Comparison of exon number. The lncRNAs represent fewer exons (∼2.8) than the other two categories of transcripts (∼10.0 and ∼3.3, respectively) on average; (c) Comparison of ORF length. The novel lncRNAs show shorter putative ORF length (∼0.17kb) than either of the two RefSeq gene categories (∼1.6kb and ∼0.3kb, respectively) on average. All means are marked by red points
