Phylogenetic relationships within Meloidogyne species: Bayesian 50% majority rule consensus trees from two runs as inferred from analysis of the D2–D3 of 28S rRNA gene sequence alignment under the GTR + G model. Posterior probabilities equivalent to or exceeding 70% are given for appropriate clades. New sequence is indicated in bold.
