MSU's discovery of plant protein holds promise for biofuel productionAugust 18, 2008EAST LANSING, Mich. - Scientists at Michigan State University have identified a new protein necessary for chloroplast development. The discovery could ultimately lead to plant varieties tailored specifically for biofuel production. Chloroplasts, which are specialized compartments in plant cells, convert sunlight, carbon dioxide and water into sugars and oxygen ("fuel" for the plant) during photosynthesis. The newly discovered protein, trigalactosyldiacylglycerol 4, or TGD4, offers insight into how the process works. "Nobody knew how this mechanism worked before we described this protein," said Christoph Benning, MSU professor of biochemistry and molecular biology. "This protein directly affects photosynthesis and how plants create biomass (stems, leaves and stalks) and oils."
Benning also is a member of the Great Lakes Bioenergy Research Center, a partnership between MSU and the University of Wisconsin-Madison funded by the U.S. Department of Energy to conduct basic research aimed at solving some of the most complex problems in converting natural materials to energy. The research, published in the August 2008 issue of journal The Plant Cell, shows how TGD4 is essential for the plant to make chloroplasts. Plants that don't have the protein die before they can develop beyond the embryonic stage. Understanding how TGD4 works may allow scientists to create plants that would be used exclusively to produce biofuels, possibly making the process more cost-effective. Most plants that are used to produce oils - corn, soybeans and canola, for example - accumulate the oil in their seeds. "We've found that if the TGD4 protein is malfunctioning, the plant then accumulates oil in its leaves," Benning said. "If the plant is storing oil in its leaves, there could be more oil per plant, which could make production of biofuels such as biodiesel more efficient. More research is needed so we can completely understand the mechanism of operation." Other members of the MSU research team are: Changcheng Xu, research assistant professor of biochemistry and molecular biology; Jilian Fan, research technician; and Adam Cornish, biochemistry undergraduate student at the time of the research and current graduate student. The research was funded by the Energy Department and the National Science Foundation. Benning's research also is supported by the Michigan Agricultural Experiment Station.

Related Biofuel Current Events and Biofuel News Articles Thinking it through: Scientists call for policy to guide biofuels industry toward sustainability As the United States and other nations commit to the path of biofuels production, a group of scientists is calling for sustainable practices in an industry that will, as MBL scientist Jerry Mellilo says, "reshape the Earth's landscape in a significant way." Mandate for biofuels production requires science-based policy and global perspective In his State of the Union Address on January 23, 2007, President Bush stated that, in order to substantially lower foreign oil imports, "We must increase the supply of alternative fuels, by setting a mandatory fuels standard to require 35 billion gallons of renewable and alternative fuels in 2017." Mustard seed meal suppresses weeds in container-grown ornamentals Mustard is one of the most widely used condiments on the planet. Prized for its oils, mustard plants grow wild in North Africa, the Middle East, and the Mediterranean, and is grown commercially in the United Kingdom, Canada, and the United States. From Sugar to Gasoline Following independent paths of investigation, two research teams are announcing this month that they have successfully converted sugar-potentially derived from agricultural waste and non-food plants-into gasoline, diesel, jet fuel and a range of other valuable chemicals. Future for clean energy lies in 'big bang' of evolution Amid mounting agreement that future clean, "carbon-neutral", energy will rely on efficient conversion of the sun's light energy into fuels and electric power, attention is focusing on one of the most ancient groups of organism, the cyanobacteria. Can biofuels be sustainable? With oil prices skyrocketing, the search is on for efficient and sustainable biofuels. Research published this month in Agronomy Journal examines one biofuel crop contender: corn stover. Novel fungus helps beetles to digest hard wood A little known fungus tucked away in the gut of Asian longhorned beetles helps the insect munch through the hardest of woods according to a team of entomologists and biochemists. Researchers say the discovery could lead to innovative methods of controlling the invasive pest, and potentially offer more efficient ways of breaking down plant biomass for generating biofuels. Turning Waste Material into Ethanol Say the word "biofuels" and most people think of grain ethanol and biodiesel. But there's another, older technology called gasification that's getting a new look from researchers at the U.S. Department of Energy's Ames Laboratory and Iowa State University. By combining gasification with high-tech nanoscale porous catalysts, they hope to create ethanol from a wide range of biomass, including distiller's grain left over from ethanol production, corn stover from the field, grass, wood pulp, animal waste, and garbage.
