Ti plasmid used for tumerogenesis in making transgenic plants belong to Agrobacterium tumificiens.

Agrobacterium tumefaciens is widely used in genetic engineering as a natural vector to transfer foreign DNA into plant cells.

Plasmids are essential in genetic engineering because they possess an origin of replication, allowing them to replicate independently within a host cell.

Agrobacterium is the most common bacterium used in plant genetic engineering due to its natural ability to transfer DNA into plant genomes.

The Ti (Tumour-inducing) plasmid is found in Agrobacterium tumefaciens and is used to transfer genes into plants.

In plant genetic engineering, the Ti plasmid can be used to carry foreign genes into plant cells. The Ti plasmid is the disease-causing agent of the soil-borne bacteria Agrobacterium tumefaciens. The Ti plasmid was then used to transform petunia cells in culture. So, the correct option is "D" (T1 plasmid transforms cells of plants).

The Ti plasmid is naturally evolved to transfer its T-DNA into the genome of host plant cells.

A vector is a DNA molecule used as a vehicle to artificially carry foreign genetic material into another cell.

Agrobacterium tumefaciens is often called a natural genetic engineer because it naturally transfers its own DNA into plant cells.
