摘要：

During a serious epidemic of crown and cane gall on the blackberry-raspberry (Rubus occidentalis-Rubus idaeus) hybrid Lockness in a specialized crop in the province of Treviso (northern Italy) Gram-negative bacteria were found associated with tumours. Following experimental inoculation these bacteria caused tumours on tomato stems and on pot-grown hybrid canes in the greenhouse. These bacteria were found to possess a Ti plasmid, common to Agrobacterium. The resulting fatty acid profile did not correspond to any known Agrobacterium species, but did indicate an affinity with the genus Agrobacterium. Partial 16S rRNA sequencing revealed that the bacteria were closely related to three strains of Agrobacterium rhizogenes, in particular with a strain isolated from a peach tumour.
