Expression of genes and long non-coding RNAs (lncRNAs) in extremely high- and low- backfat pigs based on biological replicate RNA sequencing (RNA-seq). (a) Number of differentially expressed lncRNAs (DELs) and differentially expressed genes (DEGs) between the BH and BL groups; (b) Venn diagram of genes from each group; (c) Venn diagram of lncRNAs from each group; (d) Volcano plot of DEGs; (e) Volcano plot of DELs; (f) Heatmap of DEGs in six samples. The color scale indicates the FPKM values. Orange indicates high expression and purple indicates low expression; (g) Heatmap of DELs in six samples. We have annotated the most significant DEGs and DELs in the volcano.
