Phylogenetic trees inferred from ‘Ca. P. phoenicium’ strain nucleotide sequences of genes tufB (a), groEL (b), and inmp (c). Minimum evolution analysis was carried out using the neighbor-joining method and bootstrap replicated 1,000 times. List of ‘Ca. P. phoenicium’ strains is reported in Table 1. ‘Ca. P. phoenicium’ strains identified in almond, peach and nectarine are written in bold red, blue and green color, respectively. Names of other phytoplasmas included in phylogenetic analysis are written on the tree image. Acronyms of phytoplasma names are in the legend of Fig. 1. GenBank accession number of each sequence is given in parenthesis
