FIG. 2.

Phylogenetic position of the spiroplasma of D. hydei (shaded) in the genus Spiroplasma. (A) One of the four most parsimonious trees inferred from 16S rRNA gene sequences (1,447 aligned nucleotide sites), which has the same topology as the neighbor-joining tree. S., Spiroplasma. (B) The most parsimonious tree inferred from P58 gene sequences (787 sites). (C) The most parsimonious tree inferred from spoT gene sequences (513 sites). (D) The most parsimonious tree inferred from dnaA gene sequences (474 sites). Bootstrap probabilities are shown at the nodes. Branches supported by bootstrap probabilities of less than 50% were collapsed.
