Agrobacterium tumefaciens Site Attachment as a Necessary Prerequisite for Crown Gall Tumor Formation on Potato Discs.
The infectivity of Agrobacterium tumefaciens strain B6 was inhibited about 50% when these bacteria were inoculated on potato discs with equal viable cell counts of a weakly virulent strain of A. tumefaciens (B-48) or autoclaved strains of B6 or B-48. Inhibition by B-48 or autoclaved B6 could still be obtained when these cells were added up to a maximum of 10 minutes after the addition of viable...
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 کاملProteomics of a plant pathogen: Agrobacterium tumefaciens.
Agrobacterium tumefaciens is an important plant pathogen which belongs to the α-proteobacteria. In addition, it has served as the main tool for plant molecular genetics. Here we focus on three major aspects: (i) proteomic mapping, (ii) the use of proteomics for the understanding of the response of A. tumefaciens to changes in environmental conditions and (iii) the analysis of the changes in gen...
متن کاملAgrobacterium tumefaciens-mediated transformation of potato and analysis of genomic instability by RAPD
In order to enhance the system of potato transformation and further regeneration, four potato cultivars were transformed using the Agrobacterium tumefaciens harboring â-glucuronidase (GUS) gene.The results revealed that the highest percentages of shoot formation obtained were for Spunta cv. Stem explants resulted in more callus and regeneration after transformation and selection than leaf expla...
متن کاملThe Oncogenes of Agrobacterium Tumefaciens and Agrobacterium Rhizogenes
The common soil bacteria Agrobacterium tumefaciens and Agrobacterium rhizogenes are unique genetic pathogens capable of fundamentally redirecting plant metabolism in order to generate macroscopic tissue masses (crown galls and hairy roots, respectively) which support the growth of large populations of Agrobacteria. Central to pathogenesis is the horizontal transfer of a suite of oncogenes from ...
