a The types of genes overlapping HGT regions. The overlapped Ensembl genes were extracted and Ensembl Source table were searched. The overlapped genes were identified as protein coding, lincRNA, antisense and other (processed transcript, processed pseudogene, etc.). Our pie chart compared the gene type proportions of overlapped genes against whole gene of human as the background. b, c and d Gene enrichment analysis. The gene enrichment results were shown in three aspects, biological processes (Fig. 2b), cellular components (Fig. 2c), and molecular functions (Fig. 2d). Our pie chart compared the gene function term of overlapped genes against whole gene of human as the background
