A corny turn for biofuels from switchgrass

Introducing a special corn gene into switchgrass was found to significantly boost the viability of the switchgrass biomass as a feedstock crop for advanced biofuels. The gene, a variant of the Corngrass1 gene, holds the switchgrass in a perpetual juvenile state, more than doubling its starch content and making it easier to convert its polysaccharides into fermentable sugars.
