Arabidopsis may seem like a simple plant, but at the University of Missouri, plant biochemist Jay Thelen is using it as a powerful model to explore ways to boost oil production — an important step toward creating more sustainable, plant-based energy sources.
To meet the increasing global demand for biofuels, scientists are already modifying plant genes to boost the amount of plant oil being produced. That’s because inside the plant, a complex network of metabolic pathways turns sunlight, carbon dioxide (or atmospheric carbon), water and nutrients into vital compounds including oil, the foundational ingredient of biofuel.
Genes give instructions to enzymes, and, in turn, those enzymes help control the plant’s metabolic pathways. But we are only beginning to understand how modifying these genes to produce more oil affects the plant’s other metabolic pathways, which are all interconnected.
In their new study, Thelen and his colleagues have charted how plant metabolism responds to these genetic changes. Their findings will provide fellow scientists with clues for how to tweak a plant’s oil production to create the maximum amount of biofuel.
