The U.S. Department of Energy's Office of Science, Office of Biological and Environmental Research, and the U.S. Department of Agriculture (USDA) Cooperative State Research, Education, and Extension Service, National Research Initiative have jointly selected seven projects for awards totaling $6,320,000 for biobased-fuel research. These awards continue a commitment begun in 2006 to conduct fundamental research in biomass genomics that will establish a scientific foundation to facilitate and accelerate the use of woody plant tissue for bioenergy and biofuel.
In 2009, DOE will provide $4,072,000 in funding over 3 years, while USDA will award $2,248,000 over 3 years.
Project Goal: This project will provide genomic tools and resources for a promising cellulosic biofuel crop, Miscanthus, that will (a) foster innovative strategies for its improvement and (b) develop comparative and bioinformatic approaches to enhance fundamental knowledge of Miscanthus genome structure, function, and organization.
Project Goal: This project will investigate winter survival in switchgrass populations and individual plants specifically selected for greater yields and with known differences in winter survival. Molecular events occurring in the crowns and rhizomes will be studied over two growing seasons and winters. The goal is to make a significant and lasting contribution to the future improvement of switchgrass as a bioenergy crop, and will also directly benefit researchers working on developing other perennial grasses into biomass energy crops.
Project Goal: In this project, high-throughput phenotypic analysis (phenomics) of homozygous T-DNA mutants and natural accessions of the model grass Brachypodium distachyon (Brachypodium) will be conducted to accelerate the understanding of the basic biology underlying traits that control the utility of grasses as energy crops.
Project Goal: This project will characterize genes that regulate the balance of carbon going to cellulosics or lignin, leading to the development of plant materials that are more suitable for biofuel production.
"A Systems Biology Approach to Elucidate Regulation of Root Development in Populus "
Project Goal: This project will identify key regulators of root architecture in relation to nitrogen and water use in the bioenergy crop Populus using an integrated systems biology approach. This research will generate resources and innovations that can enable robust biomass productivity under marginal conditions for sustainable lignocellulosic biomass production.
Project Goal: Biofuel crops must maximize the production of energy, which requires a high yield of biomass with optimum fuel quality. In this project, molecular markers that are associated with optimal biofuel characteristics will be identified in alfalfa and directly integrated into traditional field-oriented alfalfa breeding programs. The long-term goal of this project is to develop biofuel-ready alfalfa cultivars that have improved yield and quality.
"Characterization of Nitrogen Use Efficiency in Sweet Sorghum"
Project Goal: Enhancing the ability of sweet sorghum to utilize nitrogen will increase its potential as a leading and cost-effective bioenergy crop. This project will identify novel nitrogen use efficiency alleles in wild sorghum germplasm that can be used to improve sweet sorghum.
