FIGURE 2.

The expansion and contraction of roundworm gene families. (a) Significant increases and decreases in roundworm gene families. The solid circle and the solid triangle represent the top KEGG pathways that are enriched in the expanded gene families of Ascariasis compared with C. elegans or M. hapla, respectively. The open circle and the open triangle represent the top KEGG pathways that are enriched in the contracted gene families of Ascariasis compared with C. elegans or M. hapla, respectively. (b) GO function enrichment and gene copy number of the significantly expanded gene families in roundworms; (c) The proportion of GO functional genes in the gene family with significant expansion (or contraction) in roundworms compared to the total number of expansion (or contraction) genes. The red asterisk represents the p‐value of statistical Sidak's multiple comparisons tests of expansion and contraction of genes comparing with C. elegans or M. hapla (one asterisk represent 10⁻¹)
