Journal ArticleDOI
'Candidatus Phytoplasma', a taxon for the wall-less, non-helical prokaryotes that colonize plant phloem and insects
Giuseppe Firrao,M. Andersen,Assunta Bertaccini,E. Boudon,Joseph M. Bové,X. Daire,Robert E. Davis,J. Fletcher,Monique Garnier,Karen S. Gibb,Dawn E. Gundersen-Rindal,Nigel A. Harrison,Chuji Hiruki,B. C. Kirpatrick,Phil Jones,C. R. Kuske,I.-M. Lee,Lia W. Liefting,Carmine Marcone,Shigetou Namba,Bernd Schneider,Barbara B. Sears,E. Seemuller,Christine D. Smart,Claire Streten,K. Wang +25 more
TL;DR: The trivial name 'phytoplasma' has been adopted to collectively name wall-less, non-helical prokaryotes that colonize plant phloem and insects, which were formerly known as mycoplasma-like organisms.
Journal ArticleDOI
Phytoplasmas: bacteria that manipulate plants and insects
Saskia A. Hogenhout,Saskia A. Hogenhout,Kenro Oshima,El-Desouky Ammar,Shigeyuki Kakizawa,Heather N. Kingdom,Shigetou Namba +6 more
TL;DR: Phytoplasma can increase fecundity and survival of insect vectors, and may influence flight behaviour and plant host preference of their insect hosts, but generally do not negatively affect the fitness of their major insect vectors.
Journal ArticleDOI
Reductive evolution suggested from the complete genome sequence of a plant-pathogenic phytoplasma
Kenro Oshima,Shigeyuki Kakizawa,Hisashi Nishigawa,Hee-Young Jung,Wei Wei,Shiho Suzuki,Ryo Arashida,Daisuke Nakata,Shin-ichi Miyata,Masashi Ugaki,Shigetou Namba +10 more
TL;DR: The phytoplasma genome encodes even fewer metabolic functions than do mycoplasma genomes, and lacks the pentose phosphate cycle and ATP-synthase subunits, which are thought to be essential for life.
Journal ArticleDOI
The family Closteroviridae revised
Giovanni P. Martelli,Alexey A. Agranovsky,Moshe Bar-Joseph,Donato Boscia,Thierry Candresse,Robert H.A. Coutts,Valerian V. Dolja,Bryce W. Falk,Dennis Gonsalves,Wilhelm Jelkmann,Alexander V. Karasev,Angelantonio Minafra,Shigetou Namba,Heinrich-Josef Vetten,G.C. Wisler,Nobuyuki Yoshikawa +15 more
TL;DR: The mealybug-transmitted species have been separated from the genus Closterovirus and accommodated in a new genus named Ampelovirus (from ampelos, Greek for grapevine), and the family now comprises three genera.
Journal ArticleDOI
A unique virulence factor for proliferation and dwarfism in plants identified from a phytopathogenic bacterium
Ayaka Hoshi,Kenro Oshima,Shigeyuki Kakizawa,Yoshiko Ishii,Johji Ozeki,Masayoshi Hashimoto,Ken Komatsu,Satoshi Kagiwada,Yasuyuki Yamaji,Shigetou Namba +9 more
TL;DR: It is shown that a single virulence factor, tengu-su inducer (TENGU), induces witches' broom and dwarfism and is a small secreted protein of the plant-pathogenic bacterium, phytoplasma.
