It is a mystery how these bacteria use the sugar-rich phloem sap in which they live and how they interact with the host. Virtual RFLP analysis of 16S rDNA sequences identifies new subgroups in the clover proliferation phytoplasma group. DOI:10.1016/S0944-5013(97)80041-9. New Disease Reports, 32, 5. doi: 10.5197/j.2044-0588.2015.032.005, Jacobs, K. A., Lee, I. M., Griffiths, H. M., Miller, F. D. Jr., Bottner, K. D., 2003. Incidence of the beet leafhopper-transmitted virescence agent phytoplasma in local populations of the beet leafhopper, Circulifer tenellus, in Washington State. First report of 'Candidatus Phytoplasma trifolii'-related strain presence in Juniperus procubens witches' broom in Iran. Faggioli F, Pasquini G, Lumia V, Campobasso G, Widmer T L, Quimby P C Jr, 2004. Other potential vectors include Aphrodes bicinctus, Batracomorphus punctatus, Ceratagallia nitidula, Circulifer haematoceps [Neoaliturus haematoceps], Empoasca abrupta, Euscelis incisa, Hishimonus phycitis, Orosius albicinctus [Orosius orientalis] and O. argentatus (Weintraub and Beanland, 2006; Salehi et al., 2007; Girsova et al., 2017; Kumar et al., 2017; Salehi et al., 2017; Gopala et al., 2018; Hemmati et al., 2018; Salas-Muñoz et al., 2018). Flower C E, Hayes-Plazolles N, Slavicek J M, Rosa C, 2018. Phytoplasmas have sizes variablefrom 200 to 800 nm, they are polymorphic because of the lack of cell wall (Figure 1), and survive and multiply in the isotonic environments provided by plant phloem and insect hemolymph. phloem. Hiruki, C., Wang Keri, 2004. In India, where phytoplasmas of the subgroup 16SrVI-D are prevalent, leafhopper Hishimonus phycitis has been identified as a potential vector (Kumar et al., 2017; Gopala et al., 2018). Phytoplasma trifolii’ infection can also induce profound physiological changes in host plants. (Fig.9 9). Journal of Microbiological Methods. The phytoplasma 16S rDNA RFLP analysis also evolved from the original actual enzymatic approach to DNA sequence-based computational simulation (Wei et al., 2007; Zhao et al., 2009; Zhao and Davis, 2016).
