Figure 4.

Phylogeny and gene families of B. mucronatus and related species. The phylogenetic relationship was inferred by RAxML, based on orthologous proteins of the 497 single-copy gene families. The circle size represents gene number, and the different colors indicate different gene types showed in the right top of the figure. The numbers above (red) and below (blue) indicate number of expansed and contracted gene families, respectively. The colors of the strips within the phylogenetic tree indicate different classes of the nematodes.
