Figure 1:

Phylogenetic relationships between Pratylenchus species as inferred from Bayesian analysis of the COI gene sequences using the GTR + I + G model of nucleotide substitution. Posterior probabilities of over 70% are given for appropriate clades. Sequences generated in this study show the haplotype in parenthesis (PPH1, PPH2, PPH3 and PPH4).
