Molecular Farming: Possible Future For Vaccines.

Using genetic engineering and synthetic biology, scientists can introduce brand new biochemical pathways into plant cells—or even whole plants—essentially turning them into single-use bioreactors.

The whole idea has a retro-futuristic science fiction vibe. First conceived of in 1986, molecular farming got its boost three decades later, when the FDA approved the first—and only—plant-derived therapeutic protein for humans to treat Gaucher disease, a genetic disorder that prevents people from breaking down fats.
