Which of the following vectors is naturally disarmed and modified to deliver genes of interest into a variety of dicotyledonous plants?

  1. Retroviral vector
  2. Bacteriophage lambda
  3. Ti plasmid of Agrobacterium tumefaciens
  4. ColE1 plasmid

Correct answer · Option 3

Ti plasmid of Agrobacterium tumefaciens

Explanation

The tumor-inducing (Ti) plasmid of Agrobacterium tumefaciens has been modified into an effective cloning vector that delivers desirable genes into plant cells without inducing disease.
