Attachment, Chemotaxis, and Multiplication of Agrobacterium tumefaciens Biovar 1 and Biovar 3 on Grapevine and Pea.
Tumorigenic (CG49) and nontumorigenic (CG484) strains of Agrobacterium tumefaciens bv. 3 attached to grape roots at a higher level than did a nonpectinolytic mutant of CG49 (CG50) or a tumorigenic strain of A. tumefaciens bv. 1 (CG628). Strains attached equally well to wounded and unwounded grape roots. Strains responded differently to pea plants in that biovar 3 strains consistently attached t...
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 ...
متن کاملCharacterization of Agrobacterium rhizogenes Isolated from the Nodules of Some Leguminous Plants
Agrobacterium strains were isolated from five different leguminous plants viz., Pisum sativum, Sesbania rostrata, Vigna mungo, V. radita and V. ungiculata. The isolated bacteria was characterized and identified as Agrobacterium rhizogenes based on their morphological, biochemical, cultural and pathogenicity tests. Antibiogram and protein profile of isolates were also studied by disc diffusion a...
متن کاملDraft Genome Sequence of Agrobacterium tumefaciens Biovar 1 Strain 186, Isolated from Walnut
Agrobacterium tumefaciens biovar 1 strain 186 was isolated from a walnut tree expressing crown gall symptoms. The draft genome sequence of this strain harbored genes for crown gall formation and will be useful for understanding its virulence on Paradox, the predominant hybrid rootstock used for the cultivation of English walnut in California.
متن کاملCharacterization of Agrobacterium tumefaciens strains isolated from grapevine tumors in China.
Thirteen strains of Agrobacterium tumefaciens isolated from grapevine tumors in northern China were surveyed. These strains varied in their host range properties, although all were tumorigenic on grapevines. Twelve of these strains belonged to Agrobacterium sp. biotype 3, and 11 strains resulted in the synthesis of the opine octopine in tumor tissue. Interestingly, one strain resulted in accumu...
