Solution
The uptake of foreign DNA or transgenes by plant cells is called transformation. A variety of techniques have been used to introduce transgenes into plant cells, these can be grouped into the following two categories-(i) Agrobacterium-mediated and (ii) direct gene transfers.
Agrobacterium tumefaciens mediated transformation eliminates the need for regeneration from tissue explants.
