Maize cell wall genes identified, giving boost to biofuel research
Date:11/19/2009

WEST LAFAYETTE, Ind. - Purdue University scientists have helped identify and group the genes thought to be responsible for cell wall development in maize, an effort that expands their ability to discover ways to produce the biomass best suited for biofuels production.

The Purdue scientists, led by Nicholas Carpita, a professor of plant cell biology, published their findings on the 750 cell wall genes in the journal Plant Physiology on Thursday (Nov. 19). They also were co-authors on a study, published Thursday (Nov. 19) in Science, that for the first time sequenced the genome of maize.

In discovering the some 32,000 genes of maize, scientists can better study the function of individual genes and how each affects all aspects of the plant's development. Purdue's scientists are particularly interested in the genes that regulate cellulose, lignin and other parts of plant's cell walls.

"This gives us an inventory of the genes that could become possible targets for modification in the production of biomass," Carpita said. "We want to be able to control the structure of the cell walls."

Carpita and Maureen McCann, a professor of biology and a co-author on both papers, are part of Purdue's C3Bio research project, which is aimed at using thermal and chemical catalysts to create biofuels that utilize more of a plant's carbon. The team hopes to engineer catalysts or catalytic sites into plants and use heat or chemical catalysts to directly convert the biomass into fuel.

"The grasses, including maize, make a unique kind of cell wall," Carpita said. "Beyond the cell wall genes, having a complete genome will enable us to identify developmental controls, such as genes that delay flowering to continue production of biomass, or alter pathways so that plants accumulate more sugar in the stem."

The annotation of the maize cell wall genes also led to the discovery of more than 80 mutants involved in cell wall prod
