Field performance of modified switchgrass demonstrates a 'Goldilocks Effect'
This study showed that too high PvMYB4 transgene expression is fatal to plants in the field, whereas too low expression shows no difference from controls; but when optimal expression is achieved the altered switchgrass produces higher biomass and biofuel yields. These gains represent the potential for a doubling of biofuel production per hectare over conventional feedstocks. This is the highest potential gain reported to date from any field-grown modified feedstock.
