Phylogenetic relationship of Rotylenchulus reniformis Pasteuria (Pr3 and Pr4) to other Pasteuria spp. associated with plant parasitic nematodes (Clade 1), bacterivorous nematodes, and the Cladoceran (Daphnia magna) based on 16s rDNA sequences. The tree was constructed using 1170 bp alignable sequences with a total of 1126 positions in the final data set, and Thermoactinomyces peptonophilus and Paenibacillus polymyxa serving as out groups. The evolutionary history was inferred using the Neighbor-Joining method. The evolutionary distances were computed using the Maximum Composite Likelihood method. All positions containing gaps and missing data were eliminated from the dataset (Complete deletion option). The boot strap consensus tree inferred from 1000 replicates is taken to represent the evolutionary history of the taxa analyzed using MEGA 4.1 (Tamura et al., 2007). Branches corresponding to partitions reproduced in the in less than 50% bootstrap replicates are collapsed.
