    • Evolution of Xylem Lignification and Hydrogel Transport Regulation 

      Boyce, C. Kevin; Zwieniecki, Maciej A.; Cody, George D.; Jacobsen, Chris; Wirick, Sue; Knoll, Andrew; Holbrook, N. Michele (National Academy of Sciences, 2004)
      In vascular plants, the polysaccharide-based walls of water-conducting cells are strengthened by impregnation with the polyphenolic polymer lignin. The fine-scale patterning of lignin deposition in water-conducting cells ...
    • Understanding the Hydraulics of Porous Pipes: Tradeoffs Between Water Uptake and Root Length Utilization 

      Zwieniecki, Maciej; Thompson, Matthew; Holbrook, Noel (Springer Verlag, 2003)
      The water uptake region in roots is several hundred times longer than the root diameter. The distributed nature of the uptake zone requires that the hydraulic design of roots be understood by analogy to flow through a ...
