Genetic diversity among ‘Candidatus Phytoplasma phoenicium’-related strains infecting almond, peach and nectarine plants in diverse geographic regions of Lebanon was investigated by virtual restriction fragment length polymorphism (RFLP) analysis of 16S rDNA nucleotide sequences. Calculation of virtual restriction similarity coefficients indicates the presence of two new subgroups, -F and -G, in group 16SrIX. Obtained results open new opportunities for in-depth studies on the distribution of ‘Ca. P. phoenicium’ strains in plant hosts and insect vector populations from different geographic areas of Lebanon.

Abstract
Genetic diversity among ‘Candidatus Phytoplasma phoenicium’-related strains infecting almond, peach and nectarine plants in diverse geographic regions of Lebanon was investigated by virtual restriction fragment length polymorphism (RFLP) analysis of 16S rDNA nucleotide sequences. Calculation of virtual restriction similarity coefficients indicates the presence of two new subgroups, -F and -G, in group 16SrIX. Obtained results open new opportunities for in-depth studies on the distribution of ‘Ca. P. phoenicium’ strains in plant hosts and insect vector populations from different geographic areas of Lebanon.
