qRT-PCR array results for the PPAR signaling pathway in two pig breeds. (A) A heatmap of all qRT-PCR array genes in the PPAR signaling pathway. The colors (blue, black, and red) represent the gene expression level in the LD of two pig breeds (Min and Large White). (B) Colored map of the PPAR signaling pathway. Upregulated and downregulated genes are colored in red and blue, respectively.
