Long ago and far away I had an idea for a short story that touched on these issues of seeds gene-modified to be one-yield-only and multi-cropping. I fizzled on the story but not so hard that I shouldn't be able to pick it up again.

I'm glad for the research I did 15 years ago; I still encounter situations where it becomes relevant, e.g. this discussion here and why certain water pipes are colored purple [or other colors, but at this time I remember only what purple means].
