Optical densities of cultures grown for 24 h at 30°C in the absence and presence of phage 7-7-1. A. sp., Agrobacterium sp. H13-3; A. rhi., A. rhizogenes; A. rub., A. rubi; A. tum., A. tumefaciens; A. vit., A. vitis; R. etl., R. etli; R. gal., R. galegae; R. leg., R. leguminosarum; R. tro., R. tropici. Motile cultures were adjusted to an OD₆₀₀ of 0.03, and phage 7-7-1 was added to an MOI of 1.0. Light and dark gray bars depict cultures grown in the absence and presence of phage, respectively. Each bar represents the average from three independent experiments, and error bars represent standard deviations (Student's t test for Agrobacterium sp. H13-3, P < 0.001).
