A New Tool for Improving Switchgrass

Agricultural Research Service (ARS) scientists have developed a new tool for deciphering the genetics of a native prairie grass being widely studied for its potential as a biofuel. The genetic map of switchgrass, published by Christian Tobias, a molecular biologist at the ARS Western Regional Research Center in Albany, Calif., and his colleagues, is expected to speed up the search for genes that will make the perennial plant a more viable source of bioenergy.

Switchgrass is now grown as a cattle feed and to restore depleted soils. But interest in using it as a biofuel has intensified in recent years because it can be burned to produce electricity and, like corn stalks, can be converted to ethanol. It also grows on marginal lands, is adaptable to different regions, and--as a perennial--does not need to be replanted each year, which means lower energy costs and less runoff.
