Odyssey of agrobacterium T-DNA.
Agrobacterium tumefaciens, a plant pathogen, is characterized by the unique feature of interkingdom DNA transfer. This soil bacterium is able to transfer a fragment of its DNA, called T-DNA (transferred DNA), to the plant cell where T-DNA is integrated into the plant genome leading to "genetic colonization" of the host. The fate of T-DNA, its processing, transfer and integration, resembles the ...
متن کاملEpigenetic control of Agrobacterium T-DNA integration.
To genetically transform plants, Agrobacterium transfers its T-DNA into the host cell and integrates it into the plant genome, resulting in neoplastic growths. Over the past 2 decades, a great deal has been learned about the molecular mechanism by which Agrobacterium produces T-DNA and transports it into the host nucleus. However, T-DNA integration, which is the limiting, hence, the most critic...
متن کاملAgrobacterium T-DNA integration: molecules and models.
Genetic transformation mediated by Agrobacterium involves the transfer of a DNA molecule (T-DNA) from the bacterium to the eukaryotic host cell, and its integration into the host genome. Whereas extensive work has revealed the biological mechanisms governing the production, Agrobacterium-to-plant cell transport and nuclear import of the Agrobacterium T-DNA, the integration step remains largely ...
متن کاملTransfer of T-DNA from Agrobacterium to the plant cell.
Agrobacterium tumefaciens is the causative agent of crown gall, a disease of dicotyledonous plants characterized by a tumorous phenotype. Earlier in this century, scientific interest in A. tumefaciens was based on the possibility that the study of plant tumors might reveal mechanisms that were also operating in animal neoplasia. In the recent past, the tumorous growth was shown to result from t...
متن کاملTemperature affects the T-DNA transfer machinery of Agrobacterium tumefaciens.
Early studies on Agrobacterium tumefaciens showed that development of tumors on plants following infection by A. tumefaciens was optimal at temperatures around 22 degrees C and did not occur at temperatures above 29 degrees C. To assess whether this inability to induce tumors is due to a defect in the T-DNA transfer machinery, mobilization of an incompatibility group Q (IncQ) plasmid by the T-D...
