Agrobacterium tumefaciens is a soil living bacteria with the capacity to take control of plant cells and to reprogram them for its own ends. To do so, bacteria create a “syringe”-like channel and inject a DNA code into plants to cause diseases. This code will make the plant a welcoming place for A. tumefaciens, providing unlimited food and a stable environment. The same channel is used by notable human pathogens causing peptic ulcers, Legionnaires’ disease, whooping cough, brucellosis and typhus fever.
Another interesting aspect of A. tumefaciens biology that has been discovered recently is its unique way to grow. In contrast to most bacteria that grow uniformly along their entire lengths, A. tumefaciens use another mechanism and grow only at one pole.
