Involvement 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 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...
متن کاملجدایه جدید Spiroplasma citri جدا شده از زنجرک Circulifer haematoceps در استان فارس
جدایه‌های Spiroplasma citri براساس تحرک الکتروفورزی پروتئین و RFLP ژن اسپیرالین به پنج گروه تقسیم شده‌اند (Foissac et al. 1996). در این گزارش دو جدایه جدید S. citri که واجدشرایط برای پایه‌گذاری گروه ششم هستند معرفی می‌گردد....
متن کاملDisruption of a gene predicted to encode a solute binding protein of an ABC transporter reduces transmission of Spiroplasma citri by the leafhopper Circulifer haematoceps.
Spiroplasma citri is transmitted from plant to plant by phloem-feeding leafhoppers. In an attempt to identify mechanisms involved in transmission, mutants of S. citri affected in their transmission must be available. For this purpose, transposon (Tn4001) mutagenesis was used to produce mutants which have been screened for their ability to be transmitted by the leafhopper vector Circulifer haema...
