Biophysics of xylem embolism repair
Water stress caused embolism in plants is responsible for dramatic loss of hydraulic transport capacity and loss of
productivity or death. Thus refilling of embolized conduits is a basic physiological process that can assure competitive
edge, and plantís longevity. However, process of refilling may have to occur while majority of water in the plant remains
under tension and it seems to defy principles of thermodynamics. Experimental studying of the process remains very
difficult and it is scatted across multiple disciplines such as physics, physiology and molecular biology, while a
comprehensive understanding of the process is still at large. In my lab, we study xylem refilling under
tension using biological and physical approaches that has a potential to solve this physiological mystery.
