The bases of crown gall tumorigenesis.
The nine decades since Smith and Townsend demonstrated that Agrobacterium tumefaciens causes plant tumors (95) have been marked by a series of surprises. Among the most important of these was the report in 1958 that these tumors could be excised and propagated in vitro without exogenous plant hormones (7). Equally important were a series of reports beginning about the same time that tumors rele...
متن کاملRNAi-mediated oncogene silencing confers resistance to crown gall tumorigenesis.
Crown gall disease, caused by the soil bacterium Agrobacterium tumefaciens, results in significant economic losses in perennial crops worldwide. A. tumefaciens is one of the few organisms with a well characterized horizontal gene transfer system, possessing a suite of oncogenes that, when integrated into the plant genome, orchestrate de novo auxin and cytokinin biosynthesis to generate tumors. ...
متن کاملStrain-dependent temperature-sensitive phase in crown gall tumorigenesis.
The effect of high temperature treatments on the early stages of crown gall tumorigenesis in sunflowers was investigated. Treatments of 32 C initiated at various times during the first ten days after infection had a similar effect on tumors induced by Agrobacterium tumefaciens strains B(6) and C58. Tumor growth was sensitive to 32 C until 60 to 72 hours after infection and was stimulated by 32 ...
متن کاملHistorical account on gaining insights on the mechanism of crown gall tumorigenesis induced by Agrobacterium tumefaciens
The plant tumor disease known as crown gall was not called by that name until more recent times. Galls on plants were described by Malpighi (1679) who believed that these extraordinary growth are spontaneously produced. Agrobacterium was first isolated from tumors in 1897 by Fridiano Cavara in Napoli, Italy. After this bacterium was recognized to be the cause of crown gall disease, questions we...
متن کاملCrown gall tumorigenesis. II. Relations between wound healing and the tumorigenic response.
have demonstrated that: (a) the time required for the 1st cell division as a result of wounding is linearly dependent upon tem perature; (6) jilants maintained at higher temperatures reach a peak of sensitivity to the tumor-inducing principle more rapidly than those plants maintained at lower temperatures; (c) the plateau of maximum sensitivity is temporally shorter at the higher temperatures; ...
