Results of pan-genomic analysis. (a) Presence of different genes in the pan-genome analysis. The total number of genes is 12,461, which contains the Core gene (n = 3,604), Soft-core gene (n = 467), Shell gene (n = 893), and Cloud gene (n = 7,497). (b) The Salmonella enterica serovar Gallinarum phylogenetic tree constructed based on the Pan-genome is shown on the left. The colours in the heat map on the right indicate the presence or absence of genes, with dark blue meaning gene present and blank meaning absent.
