Conservation analysis of lincRNAs in the seven studied species. Comparison of lincRNAs exons was performed using BLAST with the native lincRNAs, with the sequences of the lincRNAS with masked repeats and with the longest ORF of all the lincRNAs. A low sequence conservation was observed for lincRNAs in insects. Five hundred ninety three lincRNAs were observed conserved in their nucleotide sequence both with masking and without masking repeats. Furthermore 43 lincRNAs showed signals of conservation in their ORFs and 68 showed indication of conservation only without masking repeats
