Experiments in Plant BioHacking

This is a little exploratory excursion away from the world of microbes, which challenges the way that we perceive familiar life forms. The pigments that give flowers and vegetables their striking colours are generally exquisitely sensitive to the environment around them so that small changes in pH (acidity or alkalinity),or the presence or absence of metal ions dramatically affects their colour. In essence then, you can take a naturally coloured flower or vegetable, and dramatically change its colour simply by changing environmental conditions within the plant in situ. No paints or dyes were used here, just subtle and induced alterations in plant biochemistry.
