“…Because phytoplasmas have strict insect host ranges 73–76) and are generally not transmitted transovarially (with a few exceptions), 77) the presence or absence of insect hosts is a critical determinant of their survival in the natural environment. In insects, phytoplasmas establish systemic infection by spreading from the gut to hemocoel, then to the salivary gland, each of which presents a barrier to insect transmissibility (Fig.…”

Phytoplasmas, a large group of plant-pathogenic, phloem-inhabiting bacteria were discovered by Japanese scientists in 1967. They are transmitted from plant to plant by phloemfeeding insect hosts and cause a variety of symptoms and considerable damage in more than 1,000 plant species. In the first quarter century following the discovery of phytoplasmas, their tiny cell size and the difficulty in culturing them hampered their biological classification and restricted research to ecological studies such as detection by electron microscopy and identification of insect vectors. In the 1990s, however, tremendous advances in molecular biology and related technologies encouraged investigation of phytoplasmas at the molecular level. In the last quarter century, molecular biology has revealed important properties of phytoplasmas. This review summarizes the history and current status of phytoplasma research, focusing on their discovery, molecular classification, diagnosis of phytoplasma diseases, reductive evolution of their genomes, characteristic features of their plasmids, molecular mechanisms of insect transmission, virulence factors, and chemotherapy.

“…To examine the positive selection acting on the phytoplasma antigenic membrane protein (Amp), we used 14 phytoplasmas: three strains of onion yellows phytoplasmas (OY-W, OY-M, and OY-NIM) (15,23) and, porcelain vine witches' broom phytoplasma (PvWB) (8) were previously described; plant tissues infected with mulberry dwarf phytoplasma (MD), eggplant dwarf phytoplasma (ED), tomato yellows phytoplasma (TY), lettuce yellows phytoplasma (LeY), Iceland poppy yellows phytoplasma (IPY), marguerite yellows phytoplasma (MarY), sumac witches' broom phytoplasma (SWB), and paulownia witches' broom phytoplasma (PaWB) were kindly provided by T. Shiomi, T. Usugi, N. Nishimura, and T. Tsuchizaki (20); DNA samples extracted from Bermuda grass white leaf phytoplasma (AYBG) and potato purple top phytoplasma (PPT) were kindly provided by A. Bertaccini (24). Total DNA was extracted as described previously (17) and used for PCR templates.…”

“…Some species of Hishimonus are known to be of economic importance because of their transmission of plant pathogens such as phytoplasmas: Hishimonus sellatus vectors jujube witches’ broom, Mulberry dwarf [27], Crptotaenia japonica witches’ broom and Onion yellows [28], Rhus Yellows, and Hovenia witches’ broom [29]; Hishimonus phycitis transmits lime witches’ broom [30], sesame phyllody phytoplasma [31], and brinjal little-leaf phytoplasma [32,33]; Hishimonus concavus Knight transmits loofah witches’ broom [34].…”

Hishimonus Ishihara is a large genus of leafhoppers widely distributed in Asia, Africa, and Australia. Its greatest diversity appears to be in the Oriental region where recent investigations on Hishimonus suggest much of the diversity remains undocumented. In the present study, twenty-eight species of the leafhopper genus Hishimonus Ishihara from China are reviewed based on comparative morphological study, including ten new species: H. fletcheri sp. nov., H. lii sp. nov., H. dietrichi sp. nov., H. kuohi sp. nov., H. tenuis sp. nov., H. hamuleus sp. nov., H. triangulus sp. nov., H. virakatmathiellus sp. nov., H. paraphycitis sp. nov., and H. yuanmouensis sp. nov. Two additional species (Hishimonus knightiellus Virktamath & Murthy and Hishimonus subtilis Knight) are recorded from China for the first time. Furthermore, three new synonymies are proposed: Hishimonus reflexus Kuoh, 1976 syn. nov. and Hishimonus biuncinatus Li, 1988 syn. nov. are reduced to synonymy with Hishimonus bucephalus Emeljanov, 1969; Hishimonus lamellatus Cai & Kuoh, 1995 syn. nov. is a junior synonym of Hishimonus expansivus Li, 1988. All the taxa are described and illustrated based on observations of specimens from China. The first study of the female genitalia of Chinese Hishimonus reveals considerable similarity among the Hishimonus species studied. A key and list of all Chinese Hishimonus species are also provided.
