Pseudomonas syringae pv. tabaci in papaya seedlings
The natural occurrence of Pseudomonas syringae pv. tabaci causing leaf spot symptoms in papaya seedlings is reported. The pathogen was identified through biochemical, physiological, serological, and molecular assays and artificial inoculations in papaya plants. It was also shown that the strains were pathogenic to bean and tobacco plants. The restriction patterns obtained with Afa I, Alu I, Dde...
متن کاملEffects of glycosylation on swimming ability and flagellar polymorphic transformation in Pseudomonas syringae pv. tabaci 6605.
The role of flagellin glycosylation on motility was investigated in Pseudomonas syringae pv. tabaci. The swimming activity of glycosylation-defective mutants was prominently decreased in a highly viscous medium. The mutants showed differences in polymorphic transitions and in the bundle formation of flagella, indicating that glycosylation stabilizes the filament structure and lubricates the rot...
متن کاملGenome Sequence of a Pseudomonas syringae pv. tabaci Strain, yuexi-1, Causing Wildfire Disease in Tobacco
We determined the draft genome sequence of the Pseudomonas syringae pv. tabaci strain yuexi-1. It was isolated from tobacco sample of yuexi-1, Sichuan province, China, by our laboratory. The genome contains 6,232,497 bp and has a G+C content of 58.2 mol%.
متن کاملIdentification of glycosylation genes and glycosylated amino acids of flagellin in Pseudomonas syringae pv. tabaci.
A glycosylation island is a genetic region required for glycosylation. The glycosylation island of flagellin in Pseudomonas syringae pv. tabaci 6605 consists of three orfs: orf1, orf2 and orf3. Orf1 and orf2 encode putative glycosyltransferases, and their deletion mutants, Deltaorf1 and Deltaorf2, exhibit deficient flagellin glycosylation or produce partially glycosylated flagellin respectively...
متن کاملOverexpression of rice OsLOL2 gene confers disease resistance in tobacco to Pseudomonas syringae pv. tabaci
LSD1-related proteins of Arabidopsis with LSD1-like zinc finger domains regulate disease resistance and programmed cell death (PCD). We cloned a rice OsLOL2 gene, orthologous to LSD1 of Arabidopsis and expressed it in a tobacco plant. Transgenic tobacco lines displayed enhanced disease resistance to a virulent bacterium Pseudomonas syringae pv. tabaci (Pst). RT-PCR analysis showed that overexpr...
