Agrobacterium: nature’s genetic engineer
Agrobacterium was identified as the agent causing the plant tumor, crown gall over 100 years ago. Since then, studies have resulted in many surprising observations. Armin Braun demonstrated that Agrobacterium infected cells had unusual nutritional properties, and that the bacterium was necessary to start the infection but not for continued tumor development. He developed the concept of a tumor ...
متن کاملThe genome of the natural genetic engineer Agrobacterium tumefaciens C58.
The 5.67-megabase genome of the plant pathogen Agrobacterium tumefaciens C58 consists of a circular chromosome, a linear chromosome, and two plasmids. Extensive orthology and nucleotide colinearity between the genomes of A. tumefaciens and the plant symbiont Sinorhizobium meliloti suggest a recent evolutionary divergence. Their similarities include metabolic, transport, and regulatory systems t...
متن کاملGenetic transformation of HeLa cells by Agrobacterium.
Agrobacterium tumefaciens is a soil phytopathogen that elicits neoplastic growths on the host plant species. In nature, however, Agrobacterium also may encounter organisms belonging to other kingdoms such as insects and animals that feed on the infected plants. Can Agrobacterium, then, also infect animal cells? Here, we report that Agrobacterium attaches to and genetically transforms several ty...

and the bar gene was transmitted through both male and female gametes and expressed in T1 progeny. Although Agrobacterium tumefaciens has been successfully used Microprojectile bombardment and gene transfer by to transfer genes to a wide range of plant species, it has received litA. tumefaciens are currently the two most common tle attention for transformation of forage grasses. Therefore, the ...
متن کاملAgrobacterium-Mediated Genetic Transformation: History and Progress
Agrobacterium tumefaciens is a Gram-negative soil phytopathogenic bacterium that causes the crown gall disease of dicotyledonous plants, which is characterized by a tumorous phenotype. It induces the tumor by transferring a segment of its Ti plasmid DNA (transferred DNA, or T-DNA) into the host genome and genetically transforming the host. One century has past after A. tumefaciens was firstly i...
