Fig. 4

Protein interaction network (a) and GO enrichment analysis (b) between PkorARF genes. The internal yellow and orange circles represent the core members of PkorARFs in Fig. 4A, while the external green circles indicate other members of PkorARFs. Gray lines represent the interaction relationship between all members of the PkorARFs gene family. The horizontal scale indicates the ratio of the number of genes in the pathway to the number of PkorARF gene family members, and the vertical scale indicates the functions of PkorARFs, including cellular components, molecular functions, and biological processes in Fig. 4b. The color of the circle indicates the significance of the proportion of genes in the pathway to the total genes (P < 0.05 is considered significant). The size of the black circle indicates the number of PkorARF genes in the pathway
