The protein interaction frequency of different group genes. Interaction number distribution of each group with whole genome protein interactions in C. elegans. Box plots of each group for protein interaction frequency. The numbers on the right side of the yellow block represent the average interaction frequency of proteins in each group. The P-values were obtained from the Mann-Whitney U test / the Wilcoxon rank sum test after the Levene’s test
