Fig 2. Phylogenetic tree of β-tubulin proteins of Ascaris species, other parasitic nematodes, and C. elegans.

Phylogenies were reconstructed with RAxML and MRBAYES. The topology shown is from RaxML. The node support values are percent bootstraps / posterior probabilities. The ‘-‘ indicates that a node was not present in the MRBAYES tree. The branches are equal length to show topology clearly; a tree with branch lengths showing divergence is available in supplementary materials (S14 Info).
