Agrobacterium are Gram-negative, motile, soil-dwelling plant pathogens with the species name given based on the disease phenotype associated with the bacteria. They invade the crown, roots and stems of a great variety of plants via wounds causing tumors. The diseases are crown gall, hairy root, and cane gall. Some strains possess a wide host range, whereas other possess a very limited host range. The tumor is correlated with the presence of a large tumor-inducing plasmid (Ti plasmid) in the bacteria. Thus A.tumefaciens causes crown gall on many dicotyledonous plants; A.rubi causes crown gall on raspberries; A.vitis gall formation on grapes; A.rhizogenes causes hairy roots; A.radiobacter is avirulent. However the ability to cause disease is associated with transmissible plasmids, and this grouping is easily disrupted when plasmids move from one strain to another. More recently Agrobacterium have been classified into 3 biovars based on physiological and biochemical phenotypes without consideration of disease; the 2 classification systems are not compatible. There is now a fully sequenced representative of each biovar publicly available.

Strain C58 is a representative of biovar I, which has also been extensively modified for biotechnological uses.
