Transmission of different isolates of Spiroplasma citri to carrot and citrus by Circulifer tenellus (Hemiptera: Cicadellidae).
Carrot purple leaf disease was first reported in 2006 in the state of Washington and was associated with Spiroplasma citri. The disease also was reported in California in 2008. The objectives of this work were to fulfill Koch's postulates and to determine 1) whether the beet leafhopper, Circulifer tenellus (Baker) (Hemiptera: Cicadellidae), transmits carrot [Daucus carota L. subsp. Sativus (Hof...
متن کاملInvolvement of a Minimal Actin-Binding Region of Spiroplasma citri Phosphoglycerate Kinase in Spiroplasma Transmission by Its Leafhopper Vector
BACKGROUND Spiroplasma citri is a wall-less bacterium that colonizes phloem vessels of a large number of host plants. Leafhopper vectors transmit S. citri in a propagative and circulative manner, involving colonization and multiplication of bacteria in various insect organs. Previously we reported that phosphoglycerate kinase (PGK), the well-known glycolytic enzyme, bound to leafhopper actin an...
متن کاملThe Repetitive Domain of ScARP3d Triggers Entry of Spiroplasma citri into Cultured Cells of the Vector Circulifer haematoceps
Spiroplasma citri is a plant pathogenic mollicute transmitted by the leafhopper vector Circulifer haematoceps. Successful transmission requires the spiroplasmas to cross the intestinal epithelium and salivary gland barriers through endocytosis mediated by receptor-ligand interactions. To characterize these interactions we studied the adhesion and invasion capabilities of a S. citri mutant using...
متن کاملSpiralin is not essential for helicity, motility, or pathogenicity but is required for efficient transmission of Spiroplasma citri by its leafhopper vector Circulifer haematoceps.
Spiralin is the most abundant protein at the surface of the plant pathogenic mollicute Spiroplasma citri and hence might play a role in the interactions of the spiroplasma with its host plant and/or its insect vector. To study spiralin function, mutants were produced by inactivating the spiralin gene through homologous recombination. A spiralin-green fluorescent protein (GFP) translational fusi...
متن کاملnovel isolate of spiroplasma citri from leafhopper circulifer haematoceps from fars province
strains of spiroplasma citri have been classified into five groups based on electrophoretic mobility (em) of spiralin protein and rflp analysis of spiralin gene (foissac et al. 1996). in the present study, two isolates of s. citri qualifying for formation of a sixth group are reported. infection of sesame plants by s. citri has been reported previously (salehi and izadpanah 2002). samples of ve...
