OOS 4 - Plant Regulation of Xylem Hydraulic Conductivity at Multiple Scales: Recent Advances, Future Directions and Ecological Implications

Monday, August 3, 2009: 1:30 PM-5:00 PM
Galisteo, Albuquerque Convention Center
Organizer:
Juliana S. Medeiros
Co-organizer:
William T. Pockman
Moderator:
Juliana S. Medeiros
This session seeks to bring together leaders and emerging scientists in the field of plant hydraulics to synthesize advances and suggest new directions for research. Speakers will present the results of original research with a focus on the ecological implications of their work in plant regulation of xylem hydraulic conductivity. The session will address regulation of xylem hydraulic conductivity at the molecular level, cellular and tissue levels, whole plant coordination of water transport and comparisons across populations, species and environments.
