Abstract:
... Damage to the plant water transport system through xylem cavitation is known to be a driver of plant death in drought conditions. However, a lack of techniques to continuously monitor xylem embolism in whole plants in vivo has hampered our ability to investigate both how this damage propagates and the possible mechanistic link between xylem damage and tissue death. Using optical and fluorescence s ...

Abstract:
... KEY MESSAGE: A high-risk hydraulic strategy might be linked to embolism recovery in Eucalyptus hybrids, allowing plants to have high hydraulic conductivity regardless of safety. Plants use a variety of strategies to mitigate or reduce drought-induced hydraulic failure. Recovery of hydraulic conductivity after drought stress can be an important mechanism used to avoid drought-induced mortality; how ...

Abstract:
... Determining the relationship between reductions in stomatal conductance (gₛ) and leaf water transport during dehydration is key to understanding plant drought responses. While numerous studies have analysed the hydraulic function of woody species, minimal research has been conducted on grasses. Here, we sought to characterize hydraulic vulnerability in five widely‐occurring pasture grasses (includ ...

Abstract:
... Minimum water potential (Ψₘᵢₙ) is a key variable for characterizing dehydration tolerance and hydraulic safety margins (HSMs) in plants. Ψₘᵢₙ is usually estimated as the absolute minimum tissue Ψ experienced by a species, but this is problematic because sample extremes are affected by sample size and the underlying probability distribution. We compare alternative approaches to estimate Ψₘᵢₙ and as ...

Abstract:
... PREMISE: Phloem tissue allows for sugar transport along the entirety of a plant and, thus, is one of the most important anatomical structures related to growth. It is thought that the sugar‐conducting sieve tube may overwinter and that its cells persist multiple seasons in deciduous trees. One possible overwintering strategy is to build up callose on phloem sieve plates to temporarily cease their ...
