Definitions for "Agrobacterium"
Microorganism (bacterium) that produces crown gall disease in the wild; it does so by introducing a part of its genetic material into the plant to direct it to make compounds it needs to live. A small piece of genetic material was isolated from this bact
Bacterial genus noted for crown gall tumor-inducing ability. Oncogenic strains are host to a tumor-inducing (Ti) plasmid which can be transmitted between species. A segment (T) of the Ti plasmid is transmitted to the plant host cell and is the immediate agent of tumor induction.
