Figure 10.Phylogenetic relationships of Longidorus cholevae sp. n. and its closest species for the D2-D3 rDNA. Bayesian Inference strict consensus tree acquired under GTR+G model. Numbers at the nodes indicating posterior probabilities higher that 0.8 and bootstrap values more that 70% for ML and NJ are presented.

Figure 12.Phylogenetic tree of rDNA D2/D3 expansion region sequences of Longidorus carniolensis sp. n. from Slovenia (square mark) and sequences of closely related Longidorus species (NCBI GenBank). Sequences were analysed using Neighbour Joining Method. Bootstrap support values higher than 50% are presented.
