Question

The best way to determine how long a plant must be exposed to Agrobacterium to become infected is to measure the number of tumours formed on plants exposed to Agrobacterium for different lengths of time. This will provide a clear indication of the time required for infection to occur. Option A will provide information about the survival rate of Agrobacterium in response to different concentrations of an antibiotic, which is not relevant to the question at hand. Option B will provide information about the number of tumours formed on plants exposed to various concentrations of Agrobacterium, but not the time required for infection to occur. Option C will provide information about the concentration of Agrobacterium in different soil environments, which could be useful, but not directly relevant to determining the time required for infection to occur.
