Problem:

I'm wondering if a plant can be programmed (by modifying its genes) to grow into any shape that it's programming instructs.

I understand that a plants genes are its instructions of how to convert the nutrients in the soil into the plant we see. So, instead of producing an apple tree or a giant sequoia, couldn't a plant be programmed to shape itself into a house, desk, or even at a stretch of the imagination, a bioship?

I'm looking for any links, or explanations of why this could/couldn't be done by anyone with more experience than I that could guide my research.

I am hoping that a plant behaves just like any other system. That it has inputs (nutrients, sunlight etc.) a function that describes it (its genes) and an output, the plant that grows. With this in mind, I suppose it would only be a matter of modifying the genes to produce the desired output (with the constraint being the available input).

Does anyone know how to go about this search to explain it.
