New discovery will enhance yield and quality of cerial and bio energy crops

New discovery will enhance yield and quality of cerial and bio energy crops

A team of scientists led by Thomas Brutnell, Ph.D., director of the Enterprise Rent-A-Car Institute for Renewable Fuels at the Donald Danforth Plant Science Center have developed a new way of identifying genes that are important for photosynthesis in maize, and in rice.
Their research helps to prioritize candidate genes that can be used for crop improvement and revealed new pathways and information about how plants fix carbon. The findings, published in "Comparative analyses of C4 and C3 photosynthesis in developing leaves of maize and rice," on October 12, 2014 in Nature Biotechnology,
C4 crops including maize, sorghum, switchgrass and sugarcane are able to withstand drought, heat, nitrogen and carbon dioxide limitations better than C3 crops, such as rice, wheat, barley and oats, due to their ability to efficiently make use of carbon dioxide and water that make carbohydrates we eat and cell wall polysaccharides; the sugars that are important to producing next-generation biofuels.
"Our research focuses on understanding complex network interactions in grasses with a goal of engineering C4 traits into C3 grasses which can be translated into crops that impact the supply of food and fuel," said Brutnell.
The Danforth Center has expanded their portfolio over the years by studying model C4 grasses to improve the quality, yield and biomass of emerging bioenergy feedstocks such as miscanthus and switchgrass and that can be applied to improve food security and major cereal crops.
