How can this be done? The technique involved are the following:

1. Agrobacterium tumefaciens mediated transformation.
2. Plant tissue culture.

1: Agrobacterium tumefaciens mediated transformation.
The Agrobacterium tumefaciens is a naturally occuring bacterium, commonly found in ordinary soil.

This bacterium has the ability to infect plant, and inject some of its DNA into a cell of the plant. The visible product of the bacterium is the well-known crown-galls.

A.tumefaciens can be seen as a kind of 'parcel-delivery service', that transports a specific part of its DNA into the cell of plants.

It is possible to change that specific part of the bacteria's DNA, which then will be transported into the plant cell.

This method is a standard procedure and is used on a daily basis in plant biotech labs around the world.

2: Plant-tissue culture.
Plant-tissue culture is plant breed and propagation on a very small scale, it is basically gardening inside test tubes.

Plant cells are totipotent, each plant cell has the ability to become any other plant cell.

For example, it is possible, to grow a new plant from some leave cells.

So, 1. we introduce DNA into the plant via A.tumefaciens. and 2. we grow new plants.

The goal of Biopresence is to introduce human characteristics to a plant, without changing the genes of the resulting plant.

How is it possible to introduce a 'new characteristic', without changing the genes of the plant? Surely this must be impossible!!!

A. sequence a piece of the plant's DNA (a plant gene) this will be, where our information will be located.

B. encode the human DNA using DNA manifolds within this plant gene, and make the new plant gene. The function of this gene is not changed.

C. re-introduce the transhuman-plant gene into the organism.

Voila!
