RESUMO
We characterized five isolates of Agrobacterium tumefaciens from naturally occurring galls on Chrysanthemum morifolium. The isolates are similar, possibly identical, members of a single strain of A. tumefaciens that we designate Chry5. The strain is a biotype I, as indicated by its response to both newly described and traditional biotype tests. Chry5 produces tumors on at least 10 plant species. It is unusual in its ability to form efficiently large tumors on soybean (Glycine max), a species normally refractory to transformation. Chry5 is unable to utilize octopine or mannopine as a carbon source. Although Chry5 can catabolize a single isomer each of nopaline and succinamopine, it differs from other known nopaline and succinamopine strains in its insensitivity to agrocin 84. This pattern of opine catabolism is unique among Agrobacterium strains examined to date. All five isolates of Chry5 contain at least two plasmids, one of which shares homology with pTiB6.
