Expression level of differentially expressed lncRNAs at all stages in Texel. There were 15 lncRNAs that were identified to be differentially expressed in all stages. The expression levels of lncRNA transcripts were estimated using FPKM. In particular, the expression of TCONS_00006187 increased gradually with development in Texel sheep. In contrast, TCONS_00013201 was expressed only in Texel 120-day-old fetus. Moreover, the expression level of TCONS_00083104 in Texel 85-day-old fetus and neonate was higher than at other stages. Finally, TCONS_00044801, TCONS_00008482 and TCONS_00102859 were expressed steadily at all four stages in Texel sheep. While the 6 lncRNAs we mentioned above show different expressed characters in Ujumqin sheep.
