a Categories in biological process (BP), cellular components (CC) and molecular functions (MF) that only existed in either the transplantation group or the original group. Detailed gene numbers of each tissue dataset can be found in Additional file 1: Table S7. b KO ID under essential metabolism and transduction pathways that are positively influenced after transplantation by Fisher’s exact test. The histogram shows KEGG annotation hits, and the gene number in the bracket indicates the amount of influenced KO in a specific pathway
