From a secondary tumor in a bean stem we have isolated a Gram‐negative bacteria, named by us T.2. These bean stems had crown gall tumors induced by the ATV strain of Agrobacterium tumefaciens . This bacterium was classified as belonging to the genus Aeromonas and possesses the capacity of inducing overgrowths in plants, synthesizing indole acetic acid (IAA). The codified phenotypic characteristics of bacterium T.2. via the Ti‐plasmid of A. tumefaciens , such as opine utilization and sensitivity to agrocin 84, have been studied. Neither octopine nor nopaline is utilized by T.2. and it is resistant to agrocin 84, whereas the strain ATV of A. tumefaciens utilizes nopaline, and is sensitive to agrocin 84.
