I suppose it's not entirely an accident that in my part of the Midwest, SW Missouri, and I gather a lot of it, maize and sorghum (around here called "milo") are the two most popular things to plant (the milo is fed to animals). My mother, however, grew up on a rice farm in Louisiana. C4 rice would be very welcome as long as there's plenty of hungry mouths to feed. As far as the biology goes, not that I'm paying any attention to the field, this is the most ambitious genetic engineering project I've ever heard of. Hope they can pull it off.
