The introduction of t-DNA into plates involves

Infection of the plant by agrobacterium tumefaciens

Altering the pH of the soil, then heat-shocking the plants

Exposing the plates to cold for a brief period

Allowing the plant roots to stand in water

Solution

Infection of the plant by agrobacterium tumefaciens

Agrobacterium tumefaciens, a pathogen of several dicot plants is able to deliver a piece of DNA known as tDNA to transform normal plant cells into a tumour and direct these tumour cells to produce the chemicals required by the pathogen.
