Field study of COMT transgenic switchgrass
The lignin-modified transgenic switchgrass had similar gains in sugar release (up to 34% higher) and biofuel production (up to 28% higher) as observed when comparing transgenic and control plants grown in the greenhouse. The greenhouse-grown experimental plant tissue was live and green, compared with the senesced, brown tissue harvested at the end of the growing season from the field experiments. The COMT2 transgenic event yielded over 50% more liters of ethanol per hectare compared with the control, which demonstrates that transgenic feedstocks could make important improvements in lignocellulosic biofuels.
