Researchers working on sorghum genetics to boost its use for bioenergy
The work was conducted by researchers from the University of Florida in Gainesville, Washington State University in Pullman, the USDA-ARS in Lincoln, Nebraska, and the University of Missouri, Columbia. They highlight disease resistance, flooding tolerance and cell wall composition as key targets for genetically improving sorghum for sustainable production of renewable fuels and chemicals.
Improving disease resistance, especially to the fungal disease anthracnose, would help expand sorghum to low-productivity land in the southeastern United States. By making the crop more flood resistant, it could be grown on land prone to seasonal flooding that is not typically used for food crops. Finally, making changes in sorghum’s cell wall composition could greatly increase the yield of fermentable sugars that can then be converted to fuels such as ethanol. The researchers are using multidisciplinary approaches to make genetic modifications linked with all three traits, with the aim of improving sorghum for renewable energy and chemical production.
