In this file photo released by the University of Florida’s Institute of Food and Agricultural Sciences, Matias Kirst poses in his laboratory on the UF main campus in Gainesville. Kirst leads a research team that received a federal grant for $643,000 to study a gene they discovered, which appears to control wood composition in poplar trees. The gene may lead to more efficient production of fuel ethanol, wood pulp and paper.
