Re: [DIYbio] Blue orchids

Not all anthocyanins are Ph dependent, I think. After all, there are plenty of blue acidic fruits? Though I don't know if the pathways for these have been well-studied.

So I want to dabble in plant genetics and have already gotten orchids from tissue cultures. I now want to turn them blue. I was going to take a pink Phalaenopsis equestris and try to alter it's genes to make more anthocyanin but it won't turn blue without a more basic pH. Is this correct and what can be altered genetically to change the pH and not kill the plant?
