Study finds link between sugar signaling, regulation of oil production in plants
Even plants have to live on an energy budget. While they’re known for converting solar energy into chemical energy in the form of sugars, plants have sophisticated biochemical mechanisms for regulating how they spend that energy. Making oils costs a lot. By exploring the details of this delicate energy balance, a group of scientists has identified a previously unknown link between a protein that maintains plant sugar balance and one that turns on oil production.

Knowing that healthy plants that produce enough sugar for them to thrive can help the plants produce more oil. I do not think they need to "Trick' the plants in producing more oil in as so much as keep the plants well fed and nourished so they naturally increase the oil production. I think this is good research and I bet more will come out of it.
