Systematic Identification and Molecular Characteristics of Long Noncoding RNAs in Pig Tissues
Conservation analysis of pig lncRNAs across species. (a) Cumulative curve of the average conservation score of the exons, introns, and promoter of protein-coding genes and predicted lncRNAs. The conservation was evaluated by phastCons scores. (b) The numbers of pig lncRNAs that can be aligned to multiple species are shown in the Venn diagram. (c) Box plots showing the SNP density of conserved and pig-specific lncRNAs. (d) Box plots showing the expression level of conserved and pig-specific lncRNAs. (e) Box plots showing the GC content of conserved and pig-specific lncRNAs.
