Xylem conduit deformation across vascular plants: an evolutionary spandrel or protective valve?
Abstract
The hydraulic system of vascular plants and its integrity is essential for plant survival. To transport water under tension, the walls of xylem conduits must approximate rigid pipes. Against this expectation, conduit deformation has been reported in the leaves of a few species and hypothesized to function as a ‘circuit breaker’ against embolism. Experimental evidence is lacking, and its generality is unknown.
