Two Novel Genomospecies in the Agrobacterium tumefaciens Species Complex Associated with Rose Crown Gall [PDF]
Phytopathology®, 2019 In this study, we explored the pathogenicity and phylogenetic position of Agrobacterium spp. strains isolated from crown gall tissues on annual, perennial, and ornamental plants in Iran. Of the 43 strains studied, 10 strains were identified as Allorhizobium vitis (formerly Agrobacterium vitis) using the species-specific primer pair PGF/PGR.

Biological Control of Crown Gall of Grapevine, Rose, and Tomato by NonpathogenicAgrobacterium vitisStrain VAR03-1 [PDF]
Phytopathology®, 2008 A nonpathogenic strain of Agrobacterium vitis VAR03-1 was tested as a biological control agent for crown gall of grapevine (Vitis vinifera). When roots of grapevine, rose (Rose multiflora), and tomato (Lycopersicon esculentum) were soaked in a cell suspension of antagonists before planting in soil infested with tumorigenic A. vitis, A.
