  1. Escherichia coli

  2. Bacillus thuringiensis

  3. Staphylococcus aureus

  4. Agrobacterium tumefaciens

Show answer
Correct Option: D
Explanation:

Plant transformation mediated by the soil-plant pathogen Agrobacterium tumefaciens has become the most used method for plant transformation. A. tumefaciens naturally infects the wound sites in dicotyledonous plant causing the formation of the crown gall tumours. A. tumefaciensis is capable of transferring a particular DNA segment (T-DNA) of the tumour-inducing (Ti) plasmid into the nucleus of infected cells where it is subsequently integrated into the host genome and transcribed, causing the crown gall disease.
