Role of bacterial cellulose fibrils in Agrobacterium tumefaciens infection.
During the attachment of Agrobacterium tumefaciens to carrot tissue culture cells, the bacteria synthesize cellulose fibrils. We examined the role of these cellulose fibrils in the attachment process by determining the properties of bacterial mutants unable to synthesize cellulose. Such cellulose-minus bacteria attached to the carrot cell surface, but, in contrast to the parent strain, with whi...
متن کاملDivalent Cation Inhibition of 3-Ketodisaccharide Synthesis by Agrobacterium tumefaciens
Zinc and copper ions at 1.0 mM effectively inhibited synthesis of 3-ketodisaccharides (3-KD) by washed cells of Agrobacterium tumefaciens. Cu2+ at 0.1 mM completely inactivated cell·free preparations of the synthetic enzyme, hexopyranoside: cytochrome c oxidoreduc· tase. This ion also inhibited uptake of disaccharides. Since Zn2+ blocked disaccharide uptake but had no effect on the synthetic en...
متن کاملMurine toxicit of Agrobacterium tumefaciens.
Eleven strains of the crown gall organism, Agrobacterium tumefaciens, tested by intraperitoneal injection into mice, were lethal within 48 hr. Five other species had some lethal strains. The lethal effect of A. tumefaciens appeared to be the result of a toxic rather than an infectious process, since histopathological anomalies were not found in mice injected with live cultures and since heat-ki...
متن کاملControl of pantothenate accumulation in Agrobacterium tumefaciens.
Two pantothenate-requiring mutants of Agrobacterium tumefaciens have been isolated. One of them (strain WMP-1) is unusual in that growth levels equivalent to the parent strain are achieved only when the medium is additionally supplemented with aspartate or another compound related to the tricarboxylic acid cycle. Extracts of cells grown on limiting aspartate were found to contain four times mor...
متن کاملPersistence of Agrobacterium tumefaciens in transformed conifers.
Previous studies have shown that the widely used plant transformation vector Agrobacterium tumefaciens can persist in genetically engineered plants in vitro and in transgenic greenhouse-grown plants, despite the use of counter-selective antibiotics. However, little is known regarding Agrobacterium persistence in tree species. To understand the kinetics of A. tumefaciens decline and persistence ...
