Unrooted evolutionary tree of AroQγ chorismate mutases (CMs) constructed with paup* 4.0. Nucleotide sequences were selected using TBLASTN searches with HsCM1 as query. gi|77799300 (Meloidogyne arenaria) was not included in the phylogenetic analysis as the corresponding protein lacked most active site residues, indicating that it is deduced from a pseudogene accumulating random mutations. Bootstrap values > 80 are indicated at each node; they were calculated from 1000 repetitions. The monophyletic cluster of nematode sequences is shaded in grey. Accession numbers and species names are listed as appearing in the tree (clockwise starting from the nematode sequences). Sequences derived from different species of one genus are listed by their accession number, otherwise the species name is given.
