As researchers the world over search for alternative energy sources, many have looked to biology to power the world. One staple crop that has already been used as a source of bioethanol, and may be able to inform other work into biofuels, is sugarcane.
Sugarcane is a highly productive plant, says the University of Queensland's Robert Henry. "I think we are all trying to understand why sugarcane is so productive," he says, adding that it's "probably related to its high ploidy. We are all looking to see what can learn for wider application."
