Summary of high-throughput sequencing data for the Debao pony (DP) and Mongolian horse (MH). a Schematic of the DP and MH groups. b Numbers of genes up/downregulated in the two breeds of horses at the two developmental stages (JS vs AS, juvenile stage vs adult stage). c Cluster analysis of the different developmental stages of DPs and MHs. The overall hierarchical clustering map based on FPKM values was generated with the log10 (FPKM+ 1) values. Red indicates strongly expressed genes, and blue indicates weakly expressed genes. The colors from red to blue indicated log10 (FPKM + 1) values from large to small. d GO and KEGG enrichment results for the DEGs in the MHPA vs DPPA and MHLBJ vs DPLBJ comparisons. MHPJ, juvenile Mongolian horse pituitary; MHPA, adult Mongolian horse pituitary; MHLBJ, juvenile Mongolian horse long bone; MHLBA, adult Debao pony long bone; DPPJ, juvenile Debao pony pituitary; DPPA, adult Debao pony pituitary; DPLBJ, juvenile Debao pony long bone; DPLBA, adult Debao pony long bone
