Brookhaven National Laboratory researchers breed new ultra-productive energycane

August 31, 2021 |

In Illinois, a team from the U.S. Department of Energy’s Brookhaven National Laboratory (BNL) has bred a plant that produces more oil by manipulating the availability of sugar for oil synthesis. The team, led by BNL’s John Shanklin, achieved these results in using leaves of the fast-growing plant Arabidopsis, to mimic stem cells of plants like energycane and Miscanthus.

The work is part of a University of Illinois-led biosystems design project called Renewable Oil Generated with Ultra-productive Energycane (ROGUE) to engineer two of the most productive American biomass crops—energycane and Miscanthus—to accumulate an abundant and sustainable supply of oil that can be used to produce biodiesel, biojet fuel, and bioproducts.

The current project, “Mobilizing vacuolar sugar increases vegetative triacylglycerol accumulation,” builds on earlier work the Shanklin group published in 2017. That work showed that simultaneously impairing the export of sugar from leaves while blocking starch synthesis diverts sugars produced by photosynthesis towards fatty acid and oil synthesis.
