    • Chemical Evidence for Cell Wall Lignification and the Evolution of Tracheids in Early Devonian Plants 

      Boyce, C. Kevin; Cody, George D.; Fogel, Marilyn L.; Hazen, Robert M.; Alexander, Conel M. O'D.; Knoll, Andrew (University of Chicago Press, 2003)
      Anatomically preserved land plant fossils from the Lower Devonian Rhynie Chert contain conducting tissues with cells that range from dark-colored, elongated cells without secondary wall thickenings to tracheids similar to ...

    • Ion Induced Changes in the Structure of Bordered Pit Membranes 

      Lee, Jinkee; Holbrook, Noel Michele; Zwieniecki, Maciej A. (Frontiers Research Foundation, 2012)
      Ion-mediated changes in xylem hydraulic resistance are hypothesized to result from hydrogel like properties of pectins located in the bordered pit membranes separating adjacent xylem vessels. Although the kinetics of the ...
