Journal ArticleDOI
Defects in flagellin glycosylation affect the virulence of Pseudomonas syringae pv. tabaci 6605.
Fumiko Taguchi,Masanobu Yamamoto,Mayumi Ohnishi-Kameyama,Masako Iwaki,Mitsuru Yoshida,Tadashi Ishii,Tomoyuki Konishi,Yuki Ichinose +7 more
TL;DR: The results supported the previous finding that glycosylation of the most externally located sites on the surface of the flagellin molecule, such as S176 and S183, is required for virulence in P. syringae pv.
Journal ArticleDOI
Genetic analysis of genes involved in synthesis of modified 4-amino-4,6-dideoxyglucose in flagellin of Pseudomonas syringae pv. tabaci
Linh Chi Nguyen,Masanobu Yamamoto,Mayumi Ohnishi-Kameyama,Salamah Andi,Fumiko Taguchi,Masako Iwaki,Mitsuru Yoshida,Tadashi Ishii,Tomoyuki Konishi,Kazuhiko Tsunemi,Yuki Ichinose +10 more
TL;DR: The results suggest that the genes vioA, vioB, and vioT are essential for glycosylation of flagellin, and accordingly are required for bacterial virulence.
Journal ArticleDOI
Flagellin glycosylation is ubiquitous in a broad range of phytopathogenic bacteria
Yuki Ichinose,Fumiko Taguchi,Masanobu Yamamoto,Mayumi Ohnishi-Kameyama,Tatsuo Atsumi,Tatsuo Atsumi,Masako Iwaki,Hiromi Manabe,Mio Kumagai,Quan Thanh Nguyen,Chi Linh Nguyen,Yoshishige Inagaki,Hiroshi Ono,Kazuhiro Chiku,Tadashi Ishii,Mitsuru Yoshida +15 more
TL;DR: The results suggest that flagellin glycosylation is ubiquitous in most phytopathogenic bacteria and that flagescence is required for virulence in Xcc.
Journal ArticleDOI
Defects in D-rhamnosyl residue biosynthetic genes affect lipopolysaccharide structure, motility, and cell-surface hydrophobicity in Pseudomonas syringae pathovar glycinea race 4.
Kazuhiro Chiku,Kazuhiko Tsunemi,Masanobu Yamamoto,Mayumi Ohnishi-Kameyama,Mitsuru Yoshida,Tadashi Ishii,Fumiko Taguchi,Masako Iwaki,Yuki Ichinose,Hiroshi Ono +9 more
TL;DR: Although the mutants had truncated O-antigen polysaccharides, and altered surface properties, they showed virulence to soybean, as WT did, and the swarming motility of the Δgmd, Δrmd, and ΔwbpZ mutant strains decreased and hydrophobicity and adhesion ability increased as compared with WT.
Journal ArticleDOI
Structural characterization of an O-linked tetrasaccharide from Pseudomonas syringae pv. tabaci flagellin.
Tomoyuki Konishi,Fumiko Taguchi,Masako Iwaki,Mayumi Ohnishi-Kameyama,Masanobu Yamamoto,Ikuko Maeda,Yoshihiro Nishida,Yuki Ichinose,Mitsuru Yoshida,Tadashi Ishii +9 more
TL;DR: The flagellin of Pseudomonas syringae pv.
