Analysis of evolutionary gain and loss events as based on predicted GHs within the Bifidobacteriaceae family. The image displays the core gene-based supertree of the Bifidobacteriaceae family, where each node reports the number of predicted GHs identified for each strain. Furthermore, gain and loss events are indicated by green and orange bars on the edge leading to each node, while the numbers placed at the supertree leaves represent the related bifidobacterial taxa presented in Table 1
