“…So far, eleven different groups (16SrI, 16SrII, 16SrIII, 16SrV, 16SrVI, 16SrVII, 16SrIX, 16SrX, 16SrXII, 16SrXIII, and 16SrXIV) of phytoplasmas were identified in ornamental plants in the world (Chaturvedi et al 2010; Madhupriya 2016). Out of these eleven groups, the 16Sr I group is the most dominant group infecting major ornamental species in India (Chaturvedi et al 2009; Madhupriya 2016).…”

“…Phytoplasma diseases are the major constraint in commercial ornamental plant production by lowering the quantum and quality gaining international importance. Phytoplasma causes different symptoms of general yellowing and stunting of plants, proliferation of shoots, phyllody, virescence, reduced size of flowers in many ornamental plants which affects their economic value (Chaturvedi et al 2010; Bertaccini 2015). The ‘ Ca.…”

Suspected phytoplasma symptoms of little leaf, yellowing, chlorosis, phyllody, witches’ broom, and stunting were observed on ten different ornamental plant species at New Delhi, Andhra Pradesh, Haryana, Bengaluru, and Pune, India, during March to July 2016. To investigate the possibility of phytoplasma etiology, PCR assays were performed using universal primer pairs (P1/P7 followed by 3Far/3Rev) specific to the phytoplasma 16Sr RNA gene. First round PCR amplification with primer pair P1/P7 did not yield expected 1.8 kb product of 16S rRNA region from any of the 17 symptomatic samples. However, 1.3 Kb amplicons were observed in nested PCR assays with 3Far/3Rev primer pair in symptomatic leaf samples of Hibiscus rosa-sinensis L. (Pune isolate), Saponaria officinalis L. (Pune isolate), and Allamanda cathartica L. (Delhi isolate). No amplifications were observed in any of the other tested symptomatic and non-symptomatic plant samples either in first round or second round of nested PCR assays with phytoplasma specific primer pairs. Pairwise sequence comparison of 16S rDNA sequences of the five positive phytoplasma strains of A. catharica, H. rosa-sinensis, and S. officinalis in the present study revealed 99–100% sequence identities with strains of ‘clover proliferation’ (16SrVI) group. Phylogenetic and virtual RFLP analysis of 16S rDNA sequences of the five identified phytoplasma strains belonging to three ornamental species further confirmed their clustering and grouping with member strains of ‘clover proliferation’ subgroup D. This is the first record of the phytoplasma association of ‘clover proliferation’ subgroup D with H. rosa-sinensis, S. officinalis, and A. cathartica in the world.

“…Epidemics of these diseases have compelled withdrawal of many ornamental plant varieties from cultivation. symptoms of general yellowing and stunting of plants, proliferation of shoots, phyllody, virescence and reduced size of flowers as well as reddening of leaves are commonly observed on ornamental plants and their occurrence often results in high economic losses (Chaturvedi et al 2010).…”

In 2017 growing season numerous examinations of Cosmos bipinnatus in Hormozgan province, Iran revealed the disease symptoms similar to those associated with phytoplasmas. Phytoplasmas were detected from all symptomatic plants by the specific polymerase chain reaction (PCR) utilizing phytoplasma universal primer pairs. Amplification, sequencing and BlAst analysis of 16s rDNA fragment (ca. 1.2 kb) demonstrated that C. bipinnatus plants were infected by a phytoplasma belonging to the 16srII group. This is the first report of association of a 'Candidatus Phytoplasma aurantifolia'-related strain with C. bipinnatus phyllody in Iran.
