Genetically engineer starchy plants for biofuel

[mattw]

For a biofuel solution (no pun intended) how about genetically engineering starchy plants that grow in poor soil. I'm thinking developing a type of switchgrass with big fruit, or maybe something with a starchy root.
Is it fairly easy to break down starch into sugar and from there into ethanol?

Roots would not be wise idea, because you!ve need to get them from the soil, clean them etc. Too much extra work.
