A School of Biological Sciences research lab, the Cousins Lab, was part of a multi-institutional team awarded a $16 million, five-year grant from The U.S. Department of Energy. The grant was lead by PIs in the Donald Danforth Plant Science Center with the aim to enhance sorghum for bioenergy.
The research teams are hoping to answer if sorghum (a drought and heat resistant grass) that can be further enhanced to increase photosynthesis and water use efficiency. The project aims to deliver stress-tolerant sorghum lines, addressing the DOE’s mission of renewable energy sources.
Dr. Asaph Cousins’ team will be focusing on biochemistry and detailed leaf level physiology. The team’s research will begin with screening for natural diversity in photosynthetic water use efficiency using stable carbon isotopes. They are trying to identify genetic controls of water use efficiency by screening populations of sorghum and mapping these traits to identify their genetic control. They are also taking a focused look on how enzyme activity and kinetics control rates and efficiencies of photosynthesis, and how they may be influencing differences in photosynthetic water use.
Dr. Cousins and his team at WSU are one of six multi-disciplinary teams. The other teams are from the Donald Danforth Center, the Carnegie Institution of Science, University of Rhode Island, University of Illinois, University of Minnesota, and the United States Department of Agriculture. The teams bring together a range of specialties from plant physiology, genetics, molecular biology, informatics, computational biology, and genetic engineering. The WSU includes one graduate student and one postgraduate student, and they are looking to add one more graduate student.
“It’s exciting to have five years of funding and to be able to pursue questions that we might not be able to otherwise in a short time frame. It also provides opportunities to collaborate with other areas of plant sciences and address these research questions from multiple perspectives and angles. This is a very interdisciplinary project”, said Dr. Cousins.
Large research grants like these are furthering WSU’s goal of drive to 25, to become one of the top research institutes in the nation by 2030.
