Based on molecular classification and the guidelines established by the IRPCM
Phytoplasma/Spiroplasma Working Team-Phytoplasma Taxonomy Group (IRPCM
, 2004), phytoplasmas have been classified into 43 'Candidatus Phytoplasma' species (Arneodo, et al., 2007; Fernandez, Galdeano, Kornowski, Arneado, & Conci, 2016; Zhao & Davis, 2016; Miyazaki et al., 2017; Naderali et al., 2017).
Although, this level of sequence divergence is higher than the recommended threshold of 2.5% deemed sufficient by the International Research Program on Comparative Mycoplasmology (IRPCM
, 2000) for defining the status of novel "Candidatus" phytoplasma specie, there is not enough supporting evidence that the agent detected in this sample could be recognized as a novel putative specie, and\or belonging to another subgroup of the 16SrXIV group.
