Q.
Which of the following statements is incorrect about Agrobacterium tumefaciens [2023]

1 It is used to deliver gene of interest in both prokaryotic as well as eukaryotic host cells.

2 ‘Ti’ plasmid from Agrobacterium tumefaciens used for gene transfer is not pathogenic to plant cell.

3 It transforms normal plant cells into tumor cells.

4 It delivers ‘T-DNA’ into plant cell.

Ans.
(1)

Ti plasmid (tumour inducing) from the soil bacterium Agrobacterium tumefaciens is effectively used as vector for gene transfer to eukaryotic (plant) cells. The part of Ti plasmid transferred into plant cell DNA is called the T-DNA.
