1. Agrobacterium tumefaciens
Agrobacterium tumefaciens is a Gram-negative bacterium found in soil which causes crown gall disease in plants (which causes tumor s to form at the crown and at the junction of the root and stem). The tumors are caused by the Ti plasmid in the bacterium; this plasmid is being heavily researched by plant genetic engineers because it is a useful way to introduce new genes into a plant cell.

2. Crown gall plasmids
A plasmid , or type of circular DNA , found in the bacteria Agrobacterium tumefaciens which infects dicot plants. Part of the plasmid inserts itself into the plant genome and causes tumors to form in the roots or in the stems nearest the roots. The plasmid has been used by geneticists, minus the tumor-causing parts, as a vector towards the genetic engineering of plants.

3. Crown gall tumor
A disease which afflicts dicot plants, caused by the bacteria Agrobacterium tumefaciens. The disease causes large tumors to form in the roots or in the stems nearest the roots, deforming the plant along its base (where it meets the ground).
