Interesting: scientists find the enzyme that codes for cold tolerance in C4 plants, which normally only grow in warm climates:
C4 plants are far more photosynthetically efficient than C3 plants. C4 = sugarcane, sorghum, corn, etc... tropical plants. C3 plants = wheat, rice, etc...
Now Miscanthus x giganteus is a C4 plant, but it has an exceptional cold tolerance, setting it apart from other C4 crops. The scientists analysed why this is so, found the enzyme, copied the trigger, introduced it into corn, and voila, now they have a corn plant that can grow for longer periods of time in existing areas, or in entirely new, higher latitudes with colder temperatures.
The same technique can be applied to other crops like sugarcane and sorghum and lotsa tropical grass species. Cool!

Oh yes, by the way, last week other scientists announced they had made drought-tolerant corn varieties. Already commercially available. None of the two breeding techniques require genetic modification. They're both based on traditional cross breeding (but nowadays that's done with some nice genetic and molecular information tools and with fast computers).
I'm not saying that this kind of breakthroughs, individually, are going to solve peak oil or the current food crisis. But if you repeat them enough, for enough crops and for enough processes, then surely they will make a difference.
There are now more brains and supercomputers involved in biotechnology and plant biology, than ever before in the history of mankind. And the number just keeps growing. The number of breakthroughs, the amount of knowledge and number of applications grows *exponentially*.
I predict that before the year 2015 scientists will have developed at least 5 entirely safe, non-GM grain crops, capable of yielding 5 tons of grain with minimal inputs, in the vast expanse of land known as Siberia. Mark my words. The Beginning is Near!
