The functional annotations based on different methods. We used three methods to infer the putative function of conserved lncRNAs. Co-expression (blue circle) refers to the lncRNA functions that were suggested according to the co-expression modules and lncRNA-protein interaction prediction. biLncRNA-PCG (pink) refers to the lncRNAs that are divergently transcribed with their adjacent protein-coding genes. Temporal expression (yellow) refers the lncRNAs that have conserved rat lncRNA partners displaying consistently up−/down-regulated expression during rat development
