Conference Program
 
Plant Cell Walls

July 30 - August 4, 2006
University of New England
Biddeford, ME

Chair:
Nicholas C. Carpita

Vice Chair:
Debra Mohnen

Cell walls constrain the final sizes and shapes of plant cells, and therefore the stature and form of plants. Plants invest over 10% of their genomes in building their cell walls. This conference will address the major advances in our understanding of the composition, synthesis, and architecture of plant cell walls and their dynamics during growth and differentiation. This meeting will bring together international scientists from academia, industry and government labs to share the latest fundamental scientific breakthroughs in plant cell wall biology. As cell walls are an enormously important source of food, feed and fiber for humans and animals, a special session will focus on the advances made in the practical uses of plant cell walls for human society.
