Other claims from this paper (7)
- Intervention effect Transfer of pTi extended strain 1D1109 host range beyond grapevine.
- Observation Two transconjugants induced tumors on the same 28 plant species as the donor.
- Observation pRK2 promoted transfer of the pTi plasmid.
- Mechanism The authors infer that pTi rather than the chromosome determined host range.
- Intervention effect Insertion of pRK2 alone did not extend host range.
- Intervention effect Insertion of pS-a into strain 1D1 caused loss of pTi.
- Mechanism The authors infer incompatibility between pTi and pS-a.
