What type of pathogen can deliver genes to transform normal plant cells?

Options

  1. AAgrobacterium tumifaciens
  2. BE. coli
  3. CBacillus subtilis
  4. DStreptococcus pneumoniae

Correct answer

A. Agrobacterium tumifaciens

Step-by-step solution

You may be surprised to know that we have learnt the lesson of transferring genes into plants and animals from bacteria and viruses which have known this for ages – how to deliver genes to transform eukaryotic cells and force them to do what the bacteria or viruses want. For example, Agrobacterium tumifaciens, a pathogen of several dicot plants is able to deliver a piece of DNA known as ‘T-DNA’ to transform normal plant cells into a tumor and direct these tumor cells to produce the chemicals required by the pathoge
