During a survey in 2016, Convolvulus glomeratus showing symptoms resembling those caused by phytoplasmas were observed in Bandar Abbas, Hormozgan province, Iran. These plants were examined for phytoplasma presence by nested-PCR assays using universal primer pair P1/P7 followed by R16F2n/R16R2. All the infected plants indicated positive results using universal primer pairs of P1/P7 followed by R16F2n/R16R2. Results of phylogenetic and virtual RFLP analyses of the 16S rRNA gene sequences revealed that the phytoplasma associated with Convolvulus glomeratus witches' broom (CgWB) was a strain of 'Candidatus Phytoplasma phoenicium'. The phytoplasma was successfully transmitted to healthy plants by leafhopper, Orosius albicinctus (Distant) which account as a vector of this phytoplasma. This is the first report on the presence of ‘Candidatus Phytoplasma phoenicium’ (phytoplasma group 16SrIX-J) in C. glomeratus and its insect vector in Iran.
