Association of 'Candidatus Phytoplasma trifolii' related strain with white willow proliferation in Iran
Australasian Plant Disease Notes 13 (17)
Abstract: A phytoplasma was identified in white willow trees exhibiting symptoms of proliferation, growing in urban areas in Hamedan province of Iran. The association of a phytoplasma with this disease was confirmed by nested PCR of the 16S rRNA gene using universal phytoplasma-specific primer pair P1/P7 and R16mF2n/R2. Results of nested-PCR amplified a product of expected size (1.4 Kb). Comparison of the sequencing results with those available in GenBank and phylogenetic analysis allowed classification of the phytoplasma into ' Candidatus phytoplasma trifolii' (16SrVI) taxonomic group. To the best of our knowledge, this is the first report on the molecular detection and identification of a clover proliferation group phytoplasma in willow trees in Iran.
