Are there any pharmaceutical companies currently using photosynthesis to manufacture drugs? What are the advantages of such an approach over traditional methods?

Great answers so far everyone! I wondered if there are any common agricultural crops that are notoriously bad / inefficient photosynthesisers? Or have they all been selectively bred to be pretty good? Which crop is the low hanging fruit in terms of evolving their photosynthesising machinery?
