[6] Grapevines that have been affected by crown gall disease produce fewer grapes than unaffected plants.

[9] The two species have overlapping host ranges, and both A. vitis and A. tumefaciens may reduce the yield of infected crops.

[9] The presence of A. vitis has been confirmed in Germany, France, Austria, Hungary, South Africa, and the United States.

[6] Crown gall disease outbreaks in Europe and North America in the mid-1980s have been linked to A. vitis, and the species has continued to survive in those regions.

[6] Additionally, a survey conducted in China from 2003 to 2009 identified strains of A. vitis on blighted banana plants.

[4] A 1999 study suggested that A. vitis is more closely related to Rhizobium galegae than to other Agrobacterium species, based on genetic sequence comparison.

[11] A. vitis may also infect tomato plants, and has been shown to cause leaf panel collapse in tobacco.

[6] Virulence genes encoded by the Ti plasmid generate single-strand T-DNA molecules, which in turn are transferred to healthy hosts.

[5] Disorganized cell division occurs in infected hosts, leading to gall development instead of the formation of healthy vascular tissue.

[7] Injuries to a grapevine caused by cutting or freezing may also make the plant more susceptible to crown gall infection.

[7] Reducing other grapevine stressors, such as nutrient deprivation and low soil pH, also limits susceptibility.

Vitis vinifera is generally susceptible to crown gall disease, but resistant grape species can be planted preferentially.

[7] Grape necrosis is a common symptom of A. vitis infection, caused by both tumorigenic and non-tumorigenic bacteria strains.

[9][12] Several ACC deaminase-producing species found in the rhizosphere inhibit A. vitis tumor production in tomato plants.
