Comparison of frequencies of NRSs in cold-resistant pigs and heat-resistant pigs. A Distribution of NRSs with significant high frequencies in cold-resistant pigs and heat-resistant pigs. The horizontal lines in the chromosome represent NRSs, with the red color indicating a higher significant difference of the NRS between cold-resistant pigs and heat-resistant pigs. The blue circles next to the NRS indicate a higher frequency of the NRS in the cold-resistant pigs, while the red triangles indicate a higher frequency of the NRS in the heat-resistant pigs. B Graph structure of a 665 bp NRS in TNFRSF1 that may contribute to the heat tolerance of pigs. C Overexpression of TNFRSF1 in skin in human GTEx data, produced through GTExPortal (https://gtexportal.org/). D Comparison of read coverage on the 665 bp NRS of cold-resistant pigs (Min), heat-resistant pigs (Bamaxiang) and three other pigs (Erhualian, Landrace and Bamei). The sample IDs on the left side of the figure are the BioSample IDs of these sample in NCBI. The sample IDs in red font represent Bamaxiang pigs, while the sample IDs in blue font represent Min pigs. The sample IDs in black font are from other pig breeds
