Figure 3. Maximum likelihood tree based on 952 positions of the F2n/R2 fragment of the 16S rRNA gene obtained from 6 samples of the present study (in bold), 20 phytoplasma strains from GenBank (used as references) and Acholeplasma palmae (outgroup). Bootstrap values (> 63%) are shown above or below the branches. Branch lengths are proportional based on the scale indicated. GenBank accession numbers and details of the reference phytoplasma strains are listed in Supplementary Table S2. The names at the tip of the tree include the following: the phytoplasma strain (acronym or Candidatus species name), the 16Sr phytoplasma group in parenthesis or the name of the insect species host, and the Country Code where the strain was detected (AU, Australia; BR, Brazil; CN, China; EG, Egypt; FR, France; IT, Italy; IN, India; KE, Kenya; KG, Kyrgyzstan; MM, Myanmar; MX, Mexico; PL, Poland; RS, Serbia; TH, Thailand; US, United States; ZA, South Africa). lab: laboratory-maintained strain. A, B and C indicate the clusters that include the samples from this study.
