There are some short stories by Paolo Bacigalupi[1] set in a dystopian post-oil future where the only fuel is grown from sterile GM crops, any non-GM varieties are killed by various GM pests (introduced by the patent owning companies). Obviously such a world works very differently to our own, with no global movement or trade; everything is hyperlocal, including information flow, and energy storage is done with mechanical springs, not electricity or chemical potential.

At least one story is about someone who reverse engineered the GM/pest resistant crops to be non-sterile again.

I found his full-length novel on the same topic, "The Windup Girl"[1], to be particularly insightful and disturbing.
