Global demand for forest products such as pulp for paper, saw timber and wood pellets for fuel is expected to increase in coming years. To meet this need, UMass Amherst plant geneticist Sam Hazen, whose research has led to higher biomass yield in grasses, recently received a grant to demonstrate that his new technology can be translated to grow trees that produce more wood than conventional trees.
The National Science Foundation (NSF) awarded Hazen a three-year, $713,000 grant to study gene regulation of cell wall growth in the model grass species Brachypodium. His experiments will advance understanding of the transcription networks that regulate secondary cell wall biosynthesis in grasses. Understanding the cell wall, which is a complex blend of polysaccharides, proteins and lignin, plus the processes and genes that regulate them, could have a big impact on commercial agriculture, he points out.
